Re: OT2: The 'realness' of languages
in this situation I would ask to show a portfolio CD or examples of software created by the person - the most important thing being experience and ability to complete a product in whatever language the person feels most comfortable. I guess it would be also fair to say that GUI will be created using Revolution RAD and definitely one can expand it with modules written in C++/C. BTW correct me please, this may be wrong impression, but it looks like C++/C adoration is something specific to the USA, isn't it? I know many IT companies in my country and elsewhere in Europe who do not do C and deliver their products (accounting systems, research software, etc...) in Delphi, Java, Abap and the fact that they do not do C seems having zero impact on their successful businesses...

Re: OT2: The 'realness' of languages
once Revolution collects the critical mass of developers and well known cross platform software products created with it, the transition should happen automagically. In general the situation is such that we have more than 50 other languages standing in front of Revolution if we sort them by popularity (www.tiobe.com), so the statistics is not on our side unless Revolution Ltd introduces something so valuable, so efficient, so universal (see list below) that everyone would not resist getting a copy of Rev... I guess some people who explore potential of Revolution for their projects might dislike the following issues: 1) lack of hardware accelerated 3D engine (what if I wish to add a decent 3D visualization feature into my software, I will be stuck if I use Revolution..) 2) objects limited to GUI (I will not be able to create my own invisible object with its properties and use it in consistent manner like other objects of Revolution. e.g. set the height of object myCube or get the mass of object Planet). I am not speaking about complicated OOP here, just about lacking possibility to create simple non-GUI objects, not resorting to workarounds. 3) pixel by pixel image manipulation is slow, in Java one can create smooth animations by manipulating individual pixels in real-time, in Revolution it is still too slow. 4) can I easily use library written in C/C++ ? No... I need to hire a C/C++ programmer to write a wrapper. Or C/C++/Revolution programmer which is yet more difficult to find. This inhibits the spread of Revolution. For example REXX language has The Generic Call Interface (GCI, http://rexx-gci.sourceforge.net/) which allows a REXX-only solution for calling external function packages without a wrapper library. Many would like a thing like this for Revolution. 5) syntax, well, at least Director folks say that popularity of Lingo increased once they introduced alternative dot syntax which requires less typing. So, they might consider choosing Revolution if they are 100% sure they will never ever need smooth 3D graphics, direct image manipulation, own objects, external libraries and feel comfortable with its syntax. I still believe we will have those things in 5 years or so... All the best! Viktoras George C Brackett wrote: I'm wondering if this has happened to you: I recently was talking with a prospective client about extending a program I wrote in Revolution for one school (the charter high school I helped found) to work with a group of schools sharing common interests. My program has worked well on two platforms for four years (we're OS-agnostic), storing data on student behavior on a MySQL database accessed via internet, and displaying the data in a variety of ways (numeric, graphical, on the web) for teachers, students, families, and administrators. Rev made it easy to write the program initially and to modify it as the requirements became clearer with use. While demonstrating the program, the prospective client (who had made it clear to me that she had been involved with many software development projects before) asked what the program was written in. After I told her I used Revolution for its rapid-development and cross-platform capabilities, a subtle change occurred in the conversation. She began talking about how I might help with the design, but that of course when the design was finished a software firm would take over the development (presumably in some 'real' language like C). I didn't bother to tell her I COULD write in C, Java, PERL, PHP and so on, because it would be extraord inarily painful to do so. Has anyone else run into this issue? Do you dodge the 'what is it written in' question? How can we raise the profile of Revolution as a 'real' language? (Never mind what religion it might resemble!)

Re: [OT] If programming languages were religions...
h Revolution is like Jehovah Witnesses. Made up of a relatively small albeit stable and friendly community of followers and controlled by a small company Revolution somehow resists the power of mainstream beliefs with large evil corporations behind. Although well known for its pacifistic attitudes, it cherishes a hope since the very establishment that this evil World is moving to the end, and the Revolution is going to dominate the New World soon. Believing the God's name has to be written and pronounced using rules of the English language, its followers read and interpret the Scripts literally. However this might have raised some doubts about the trustworthiness of the word about Revolution because of experiences caused by diverse national, linguistic and religious identities. The partisans of Revolution strongly believe that many dogmas and assumptions of mainstream religions are incorrect interpretations, bad habits and even superstitions. Meanwhile adherents of the mainstream religions usually look at revolutionists from above. However the later tend to became converted after just a few days of hands on experience with Revolution. --- sorry, I could not resist to write one more, as it was also missing from the original list of languages :-) --- Assembly - the language in which the Universe has been created.

Re: Sqlite remotely
there is one trick to make it working like a multiuser database. The same trick was frequently used in all flat-file based multiuser environments (mostly websites). I did not try it with Revolution yet, but did many times in Perl (CGI) and it works. It is not lightning fast, but multiuser. A verbal simplified description of this ancient recipe is: (1) Before updating database check if file sem.txt is present. (2) If it is present - wait a few milliseconds and check (1) again. (3) Otherwise if it is not present, create sem.txt and start updating the database. (4) When the job is finished, delete sem.txt, so that another process won't see it. one implementation of sqlite that is able to access remote sqlite database is Apache modsqlite module.

MetaCard engine is neither free nor open source, because it is Revolution engine. MetaCard IDE is free and open source, but it is just an IDE. One can also freely choose to use Revolution demo... In both cases users need to buy a license to have a full featured IDE, otherwise, I guess, scriptlimits will show their power. The only product it theoretically can compete with, as far as I understand, is Galaxy IDE. But new users of Revolution usually start with what they can get with no additional payment and only later try or upgrade to Galaxy if they like it more than any of the free alternatives they already have (Native Rev IDE or MetaCard).

Re: [Heads Up:] OLED Buttons
Oh, they have finally released this! Some time ago Art. Lebedev studio offered to pre-order their keyboards when the final product was just in a stage of concept. Its good to see they have succeeded.

One could even get real 3D buttons with a lenticular or parallax barrier screen and a feeling of click feedback via vibration on touch.

Re: Semi-automatic Index generation?
Hi David, you might wish to discard the 1000 most frequently used words from your list: English: http://web1.d25.k12.id.us/home/curriculum/fuw.pdf German: http://german.about.com/library/blwfreq01.htm Another approach is statistical - take the whole text, sort words by their frequency (count) of appearance in the text. If you put them on a graph you would notice characteristic 'power law' distribution. Set the absolute or relative frequency or count value at which to cut the tail. This tail is what holds all the rare or interesting words of the text. For example if the text is large you may discard the first 500-1000 words in the list sorted by word count. All words that remain should be the ones that are more-less interesting. The easy way produce such a frequency list is by using arrays. The principle is like this: local arrayWords repeat for each word myWord in theText add 1 to arrayWords[myWord] end repeat now the keys are words and values are word counts in arrayWords.

Both options are very attractive to all sorts of visualizers like architects, engineers, CAD and GIS people, scientists or game developers because at the moment they mostly make a potential but not yet (fully) realized ecological niche of RR's customers.

If before loading your image you do this: set the paintcompression to RLE (which is the default in standalones) the same color replacement handler takes just 77 milliseconds, which is ~ 9 times faster! Now if only we'd know what exactly rle format is used by RR, then we should be able to do: put the text of img im1 into myData replace myColor1 with myColor2 in myData set the text of img im1 to myData unfortunately now this damages the image but otherwise it would take only ~25 milliseconds.

Re: PNG with No Alpha Channel?
Hi Trevor, if you export image as paint, then it is exported in ppm (portable pixelmap) format (uncompressed RGB without alpha channel). You can load ppm files with Rev too. Viktoras Trevor DeVore wrote: I need to export a PNG image from a Revolution image control that has no alpha channel information whatsoever. The 'export' command seems to always include the alpha channel even if there are no transparent areas in the image. I've also tried loading an image file into an image control an transferring the imageData to another image and then storing the text of the second image in a file (paintCompression set to png). The file still appears to have an alpha channel though. qrtPDF says the file does and Preview on OS X gives me the option of whether or not to include the Alpha channel if I try to export the resulting image from Preview.

ask file with filter/type - how to read the selected type ?
is there any way to know what file type user selects in ask file with filter dialog ? I need to specify different handlers for file Save as, and now am first asking user to select the type of a desired output (i.e. raw binary, ascii text, png image or ppm image) and next opening ask file dialog to get the path for saving the data. But I know this is not good, because users are used to a single dialog for file saving where they choose save as type and the data is processed without any additional disturbances... The problem is that the selection of ask file dialog is returned in 'it' variable but the selected type of file in the dropdown list of that dialog is not returned in any readable way, or is it?..

Re: ask file with filter/type - how to read the selected type ?
Jacqueline, Thanks for the suggestion, still 'the result' after execution is empty. It would probably contain something if path selection failed. The other 'result' (path stored in 'it') does not always contain an extension. If user types it in, or chooses from a list of existing file names, then it is there. But otherwise if user provides file name without an extension, script has to check what was the file type selected, appends correct extension and directs output to a necessary processing handler. It knows file type just because it asked about it before asking for the path. Now I guess if I wish to avoid displaying a chain of dialogs, I have to design own custom askFile() function or handler. The only role of ask file with type or ask file with filter that is described in the dictionary seems to be limited to displaying existing filenames whose types match the one selected in the file type list...

Re: Is RR too easy? Or too hard? (was) Is RunRev marketed to developers mainly?
Thats why it would be nice to have Revolution name mentioned regularly in the big IT magazines. Once it gets there the snowball effect will start working as local national magazines tend to replicate news printed in the greater ones. These news in turn get replicated by IT columns in local newspapers. For the old school we can probably say that indeed, you can enjoy coding by writing your own externals in C++. B.t.w, now as we know how to do it in C++ it would be also nice to have tutorials on writing externals (if possible) in C, Visual Basic, Pascal, D, Ada (check the tiobe programming language ranking at http://www.tiobe.com/ to see why). Learning by example is the most efficient (and likely the only) approach to learn new things. The old school is actually now being replaced by folks that do php, perl, python, rubby. And finally there is a growing community of javascript/ajax, xml, flash/flex/actionscript programmers and database people. The situation now is that more and more software is being written in interpreted languages then in compiled ones. But if Revolution remains unprinted (=unheard), then it can't reach people efficiently. V. -- Computer programming is a fluid situation. There is a momentum that must be hit for a language to be accepted within the old school programming community. And frankly I don't ever see RR hitting those folks. Which is ok with me, lets move forward instead of trying to convert a bunch of old ways are best programmers. In the end, whatever tool you use to accomplish the task at hand is the one you want to use.

Re: Getting things the wrong way round . . .
Well, I do not insist anyone looking through all the world languages for possible associations of the new worlds we create to be used in marketing, but by chance it just happened so that the correct pronunciation of Myrie [mirai] at least in Lithuanian (now one of the official languages of the EU) looks like it is directly associated with death [mirti, mire, mirei]... But due to nature of our language most people will tend to pronounce it as [Miri:e], which sounds different. B.t.w. this is just a funny fact, not a complaint. Lithuanian market is comparatively very small - there are more people living in Athens then speaking our language. I know of only 2 programmers using Revolution here (though likely there are more), and we do not pay too much attention to funny associations in names of foreign companies and products unless it is a direct match :-).

Re: Table Fields
As far as I know table fields are reliable now. A while ago some nasty bugs were reported (e.g. in compiled apps modifying a cell in a table did not in fact updated the underlying table in some cases) and now they are fixed. However, I already got used to using ordinary text fields with table gridlines switched on and a bunch of scripts to make these fields behave more like tables. I think given enough motivation (stress, fun, money ;-) ) someone should be able to create such a perfect generic standard reusable table object using combination of existing text fields and other objects in rev. And I know a few examples that can be reused. Nevertheless, for most tasks gridded text field with a few scripts is more than sufficient (displaying database contents, calculations, etc...)... However, a few default features that would be nice to have in those text fields would be possibility to resize the cells by dragging vertical gridlines with mouse. This is based on feedback from my own clients - they usually ask why in my apps they can not contract or expand table collumns by dragging column borders with mouse, or make cell resize to match its contents on left-doubleclick... I know this is possible to script, however, somehow did not try yet to create such a useful script myself :-). Also cell addressing with commands like answer the cell A3 of fld myTable or get the cells A1:B10 of fld myTable or put the cells A1:Z1 of field myTable into fld myHeader would be very useful for any text field, not just tables...

Lots of talks about metadata standards, formats and profiles (ISO 19115, ISO 19139, netcdf, etc...), data semantics and ontologies, as well as various combinations of GIS and relational databases. Current trends in information systems were discussed and many examples of working systems and technologies in use were presented during both talks and poster sessions. It was interesting to observe a noticeable increase of Apple macosx and linux pc laptops brought by participants :-). Fortran is still in wide use, Adobes' Flex is on the rise. Lots of posters about use of google maps, mashups, a noticeable boost of different open source and related technologies (postgresql, mysql) in use. Increasing interest in near-real-time monitoring systems. Revolution (logo, brief description and url in the tools section) was exposed in 2 posters. However no participant, or at least those that I had an opportunity to talk to, have heard anything about it before and I had to explain what it is.

OOP in Rev...
I would like to define a class, an object (the both with their properties) and methods that are not a part of graphical user interface or Revolution engine... Let's say I need an object City having properties: minLatitude, maxLatitude, minLongitude, maxLongitude, area, populationSize, growthRate, dateFounded, currentDate so it can be handled using specific handlers and functions (e.g. its methods). Or, well, it would be more correct to start with creation of a class City or templateCity and then use it to create new city objects (NewYork, Paris, etc...) that can be processed by their functions like populationGrowth(Paris, start_year, end_year) and so on... The three approaches that I can imagine are somehow inter-tangled: (1) creating an object as a custom property set of a stack or (2) creating it as an array or (3) creating it as an invisible control with custom properties. But all these have their drawbacks. The (1) and (3) approach allows attaching handlers to custom properties and allows accessing object (e.g. a custom property set) properties using both an array notation (somehow an equivalent to an array-like behavior of objects in javascript) and in a way consistent with handling of properties in Rev e.g. set the .. of .. to ... or get .. the .. of Unfortunately (1) allows only a single object to be active and thus accessible. The (3) is a dirty one, because object is created using empty controls with their own additional properties and methods. The (2) looks promising, one can create a class, write a constructor function that would create new objects from the class, etc... But it lacks consistency with the existing OOP style in Rev - e.g. you can not get or set an element of an array using get the element/property of array/object or set the element/property of array/object to value. Besides you can not use getProp or setProp handlers with array's elements. Did anyone try doing something like this kind of OOP in Rev? I would appreciate if you can share your thoughts, warnings, tricks and approaches :-). I am not looking for a complex C++ like style of OOP in Rev. Anything simpler like the OOP model of javascript would be OK. In general, I think, it would be nice if one could treat and access Revolution arrays as objects with custom properties, with all the getProp, setProp and templateObject stuff...

Re: OOP in Rev...
Hi, me too like rOOP, but I feel it is a little incomplete, just one more step. The ones that you call real objects are limited to user interface controls only. The thing I was curious about is a possibility to create an independent data object which is nor control neither a gui element. Which in this case may simply mean enhanced arrays... What for ?. I think this would make code cleaner and reduce amount of commenting in larger projects.. Also facilitate creation or adoptions of existing libraries in C or C++ for very specific purposes - like reading shapefiles, netcdfs, doing geographical transformations, astronomy, bioinformatics, etc... This consequently will increase the scope of applications that can be created in Rev and hopefully availability of diverse libraries. In general it would make creation of complex software easier. We can already simulate objects using arrays, but at least the code would be more readable (!!!) if I were able to distinguish array operations from object manipulations.

One more interesting thing Scot mentioned there is right before the paragraph about the completion of OO features where he wrote about possibility to output java bytecodes: A method for outputting Java byte-codes equivalent to MetaCard scripts has been designed, but implementation has been delayed until the serious performance, compatibility, and functionality limitations in Java have been rectified. Nice idea :-). Viktoras Richard Gaskin wrote: --- I believe Mark Waddingham has hinted in the past that adding OOP extensions to Rev would be an interesting thing to do.

I had a quick look at your link and staggered back, appalled. It reminded me of what a gentleman named Robert Lipe said to me on another list when he thought I was trying to reverse engineer the USB interface of my device (maybe I was - I had not considered Rev in the equation at that stage and had even less idea what I was doing). His advice started off: Reverse engineering USB protocols from scratch is possible, but only if you pass the entrance exam: Repeatedly jam a fork into your left eyeball.If, after about 40 jabs, your thought is man, this is great - my right eyeball needs a piece of this action, then reverse engineering USB protocols just might be your calling. I think I will just go back to sleep on this unless and until I can find out something more about the device I wanted to interface with. I suppose that I was seduced by the enormous number of USB-connected devices that surround me - right here where I'm sitting I can count 2 digital cameras, a printer, a scanner, a hard disk, an ADSL modem, a keyboard, three mice, a GPS training device, a SatNav, an Elgato TV receiver, a webcam, a digital storage card reader and a data key. Who knows what else I might find if I go into the other rooms in the house? And to think that the people who engineered them all had to write drivers for PCs and Macs, and (no doubt) they are all different. Compared to that, Rev programming seems so easy, doesn't it?

I do believe there is at least some level of demand. Graham You're certainly correct that USB is well-defined standard, evidenced by the many uses of it on all computing platforms and beyond. And as you might imagine, the USB standard is necessarily complex to do all it does. Here's a good introduction to USB: http://www.beyondlogic.org/usbnutshell/ I manage development of a system that uses a USB HID input/output device. The device has 9 backlit input keys whose lighted states and key events are managed/handled by a Rev-based app. The Rev app has no direct interface with the device driver; it interacts with the driver via a pass-through background app that provides a socket interface to the Rev app. On the Mac, the driver is actually a custom-built Kernel Extension (.kext) file; on Windows it's the Win32 version of the libUSB open-source library ( http://libusb-win32.sourceforge.net/ ). I imagine there may be better ways to implement this, but it is what it is. :o) It's the way we found we could make it work when it was initially needed.

real time monitoring, etc... was Revolution Reading GPS Data,
...trying to figure out more than one (well... two) way of how one can make Revolution read a constant data stream coming via sockets, never ending log files, GPSes or any other real time monitoring system. Application has to display the changing status of these readings and in the same time have the user interface with all the buttons and menus completely responsive to user actions. So far the only way I can imagine is creating 2 separate applications - app_1 reading the monitoring data constantly and displaying it, app_2 controlling the first via shared file, socket or a database. The shared resource has to be scanned repeatedly by the app_1 for the control commands. However the problems with this approach are: 1) data flow reading process has to be interrupted to scan for control parameters and therefore readings are incomplete. Otherwise if I specify read from ... until end app_1 will turn into something user losses the control over, because there is no end. In this case the only remaining control is to switch the app_1 off by killing its process; 2) application GUI has to be split into 2 separate windows, I would prefer having both app_1 and app_2 in a single window. Are the other ways to handle this in Revolution without having to write an external handler in C++?

Re: Team Development using Run Rev
Unfortunately a few functions in Rev require use of ID (or long ID) when referring to objects... RevDictionary says: use the altID property to specify an additional ID for an object. Both the ID and the altID property are checked when you refer to an object by ID. Of course it would be nice to have a possibility to set any ID from script (should we ask for an enhancement, is this possible at all?). Meanwhile I wonder whether altID approach works reliably in all cases. B.t.w the dictionary warns: be careful not to set an object's altID property to the ID of an object of the same type. Since both properties are checked when you refer to an object by ID, doing this may cause the wrong object to be found because its altID property is the same as the ID of the object you want. Gotcha: how do we know in advance what ID will be assigned to an object to avoid matching ID and altID of two different objects? Will the Revolution engine check uniqueness of both IDs and altIDs? Is there any way to ensure that no ID and altID for any two objects match ? All the best!

Re: DP 4 for Linux: Aaaarrrggg!
Hi Peter, just tested this on my Linux (ubuntu 6.06 xfce, kernel 2.6.15-29-386) and it looks like it is working. E.g. I open Rev beta dp-4 and it loads in the 2nd desktop, then I opened Rev dictionary and send it to 3 desktop, created new stack and sent it to the 4th workspace. Then searched the dictionary, went to 2 workspace to check if IDE is still there, then went to the 4th and closed the stack. It works so far without collapsing to a single workspace. Maybe there are some desktop settings to explore, although I used all defaults...

But that is not what is meant by working with no problem. Can you put the different windows on different workspaces, in the way Sarah describes, and work on them? Can you, for instance, put the script editor and the application browser on one desktop, the dictionary on a different desktop, and your app you are designing on a third, and have them all stay where you put them and work in the different windows as you choose, by flipping from one desktop to another? I cannot. They all move instantly back to the same desktop the moment I use anything. I'll have to do some research on locking. Maybe there are hacks. But at the moment, it does not work like I expect it to - like OO works for instance, where the dictionary equivalent can be moved to a different desktop and just stay there while you work on your spreadsheet.

At least there is a workaround - just use xfce, which I quite like these days, though whether it is any longer the low cholesterol desktop is another matter...

Re: OT: New threat to our way of life: giant pythons
Hi Mark, invasive alien species are an increasing problem globally. Species that were introduced deliberately or accidentally into new areas now have more chances to adopt and survive also because of the global climate change. Not all species are as bad, some are endangered, but some are nasty indeed causing damage to natural ecosystems, human health or economies. For example there are around 10 000 species like this in Europe that counts to 45 000 distinct introduction events. If you are interested in this topic you can visit www.europe-aliens.org and take a look at the poster presented in the conference Biological invasions in Europe and the DAISIE initiative - current threats and future perspectives at http://ekoinf.net/daisie/poster_easd_overview.ppt, ~3 Mb. Actually this is not a big OT, because Revolution was used extensively and intensively to create the European Alien Species Database and data exploration tools to be released for public access in 2009 (database is still being polished, besides scientists wanted to make all their relevant publications before the database content is completely exposed). I will be taking that poster to at least 3 other conferences, so Revolution will get its exposure there too :-). Some facts on the best known aliens... Freshwater bivalve mollusk Dreisenna polymorpha caused huge losses in the USA by clogging water intake/release pipes and other submerged structures in Great Lakes. A tiny crustacean Cercopagis pengoi upon its arrival to the Baltic sea caused what was called nets plaque nearly destroying marine coastal fishery business in a few European countries at the turn of XX / XXI centuries. Xilophagous mollusk Teredo navalis destroyed nearly all wooden constructions in San Francisco bay in the beginning of XX century causing loses as high as 200 000 000 dollars in just one year. And very recently documented new invader Mnemiopsis leyidyi is a major threat to fish resources in the Baltic sea, because it preys upon juvenile fish and has no natural enemies. This really beautiful creature already caused collapse of fisheries when it invaded the Black sea some time ago.

Here are a couple of quotes from Scott Raney about it: Hi Jacque It wasn't the script content I was concerned about. Scripting problems exist wherever the engine is. My concern was that if the engine is in the cgi-bin folder, you can attempt to call the engine directly. For example, if the engine is named rev, then what happens when you request the url http://some.server.com/cgi-bin/rev; Will Apache try to start the engine? My understanding of Apache and the cgi-bin folder suggests that it will. (But am not certain.) Normally, I think nothing will happen and the engine will immediately close. But if it were possible to coerce Apache to send parameters when opening the engine, the risks seem higher. In the case of the Windows Perl executable, I think Apache sent any query string attached to the url as a parameter. In some circumstances (forget details) the Perl executable will attempt to execute scripts passed as parameters. It was possible to craft a query string that would cause Perls to execute scripts. As I said, I'm reasonably confident this can't be done with Rev. (But it will accept parameters.) But it's usually not a problem to put the engine somewhere outside of the cgi-bin folder and adjust the top line of the script accordingly. The other advantage is that starting a script with #!usr/bin/revbin/rev or #!../rev makes you look more knowledgeable than simply using #!rev It's like the subtle difference between quiche and egg pie.

Re: Cgi and Database (stick to standards)
from my experience mysql is faster than sqlite in joins, unless you manually optimise your sql queries for sqlite ;-), in most cases using subqueries. Plus mysql is multiuser and omnipresent, which matters... To make sqlite multiuser you will have to implement your own database locking mechanism, or use tools that have it already implemented (like modsqlite for apache). Possibly valentina db is one of the best choices (and I am waiting for my valentine days license to test it without limitations :-) ), but if you buy hosting services, then I guess you are limited to mysql, sqlite and sometimes postrgresql (which people say is slower than mysql...).

Re: Many Cards vs. Lists vs. XML
working with lists is much much faster. XML is just plain flat text file with more text to process. If you have large and complex dataset with items, children items their relations and properties, then it is more efficient to use relational database for data storage and retrieval... XML suits best to present data stored elsewhere it is rather like document on steroids or interactive document or communication/data exchange protocol that can be formatted, trasformed or scripted itself (e.g. XHTML) to present data in different ways. Although it is fashionable to use XML everywhere, including data storage, i would tolerate it only in those cases where you have relatively small amount of complex data. E.g. like rss feeds that are usually limited to 10-15 items. For large amounts of simple data in form of key-value pairs ordinary list is possibly the best solution. In all other cases use real databases. The perfect delimiter is tab :-). If you use list and data already contains tabs, then before populating the list replace tab with some unlikely combination of symbol(s) like \t and replace those back to tab when retrieving data. Same can be done with multiline data - replace return with e.g \n for storage and then replace \n with return for displaying. If you go with relational databases (sqlite, valentina etc...) there will be no problems because you won't need to deal with any field delimiters then (except those cases where you have to import data from delimited text file). All the best Viktoras Russell Martin wrote: So, I've been reading up on Rev's XML features and I'm wondering if that isn't a better route to go than using lists? Any thoughts?

Re: Inter-Application Communication on Windows
Hi, I wonder whether it is because the instances change the schema of the database or because they do it simultaneously ? Maybe if you implement a simple locking mechanism it would work ?.. The simplest way, which I never tried in Rev, but many times in Perl when programming multiuser shared flat file based solutions is using a semaphore file. When an instance of app needs to write data to a shared flat file it: 1) checks if semaphore file (an empty file with known name, e.g anything like busy.sem, busy) is present 2) if it is present it waits and returns to 1) in a few milliseconds otherwise it 3) creates the semaphore file and writes data into the shared file 4) then deletes the semaphore All the best!

Re: Inter-Application Communication on Windows
Hi Dave, in one of my applications I use shell to communicate with sqlite for data .import and revolution's sqlite to query and modify the same database. It was never corrupted...

Re: Threshold filters (Rev Newsletter #48)
...from my observations put before tends to slow down with larger files. So put after is the fastest of all... V. Björnke von Gierke wrote: A very interesting read, and it fits nicely into your expertise. However, you use put into in the last example (repeat for each). This negates the speed gain you'd get by using for each. try to use put after or put before. I made some tests, and it increased the speed of the loop alone by up to 10% for me. Of course it also needs double the ram :) ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution
taskbar applications
i would appreciate a few hints on how do we create taskbar applications in Revolution on Windows. I.e. something like Revolution player, skype or anything like that where user sees an icon of a running application sitting in the taskbar. If he clicks that icon with mouse - context menu appears... How do we set application to be loaded on startup automatically ? I would like to add this option to preferences of my app, will it have to mess with windows xp registry or are there other ways? Any hints, online tutorials also on how do we do this on Mac, Linux ? Many thanks in advance!

Re: db encryption and multiuser question
Hi Tiemo, try this sqlite database editor (for windows): http://www.yunqa.de/delphi/doku.php/products/sqlitespy/index Or you can install an sqlite plugin for Mozilla web browser. Regarding the encryption and a few other issues (like loading tables into the database using sqlite's .import function) it is possible to communicate with sqlite using shell. From time to time I am forced to resort to this option.

Re: AW: db encryption and multiuser question
Hi Tiemo, it won't work that way. Sqlitespy uses its own disqlite for encryption, etc. In your case you should consider any of the database servers (Valentina, MySQL, etc...) that support both multiuser databases and encryption. Best wishes Viktoras Tiemo Hollmann TB wrote: Hi Viktoras, ok, as I see I could encrypt the db with sqlitespy, but I think I would need sqlite-crypt for decrypting the db from within my app. What I am not clear in is, how sqlite-crypt works together with runrev. Do I just have to copy the crypt-dll into my app folder and call the open function instead of the standard revdb function (what about registering / declaring of sqliste-crypt), or how does the communication between runrev and sqlite-crypt looks like? Perhaps I am asking the wrong questions?

Re: filling a db on CD, what happens?
what about storing data to an external database on a remote server ?.. Or is the data too user specific or privacy sensitive (or how is it called correctly in English?..) and there is no point to save it at all? What about using usb flashdrive instead of CD ? Or simply putting the application online to be downloaded and installed locally or maybe load and run directly from the web server, if it is small enough ?
