My understanding of dynamic arrays was that the compiler created a 4 byte field before the first element that contained the length of the array. So why does the sizeof function not reflect this ? And why do I need 16 bytes not 12 (4 for LogType + 4 for length of array + 4 for array pointer)? Also regardless of the number of items in the open array parameter, 16 bytes works, so it does not relate the length of the TConstArray. Your thoughts ?

Re: [DUG] Validate data entry
Hi Wallace, Don't know if you missed my post or not but if you do your validation on the OnDataChange event on the TDataSource component, it gets triggered everytime you modifiy a field value. So if you are in a DBGrid and you change a value in a column and then move to the next column, the event is fired. OnValidate happens before posting but OnDataChange occurs whenever a field is modified of if you scroll to new record. If you move to a new record you just ignore it by testing the Field parameter is nil. Cheers, Colin On 2 June 2011 18:00, Marshland Engineering marshl...@marshland.co.nzwrote: Form inheritance or Frames to cut down on the number of different entry points. The program is set of sequences for machining. A DBGrid displays the operations. On double clicking the DBGrid operation, opens a form with the relevant data and the graphics is displayed. The data entry points are placed on the graphic at the point of interest. So each entry form is completely different. The machining steps are Thread, Rough Turn, Plunge cut, Face etc and all can be internal as well. However for example - each form has a Depth Of Cut that has a range of 0.02 -2.5 mm. My thoughts -Create a new DB aware component that has a maximum and minimum range and use it on each form. Not ideal as I have to ensure consistency between all forms. -If I use OnValidate in the DM, when is this event triggered? On Post ? If so then I could have several errors occurring at the same time when the data validated, which error belongs to which field ? If I use OnValidate - when I append a record, will it run all the OnValidate procedures at once ? It looks like I may have to split the operation into to parts - check that the data entered is in the correct format (Form Property) and another to check it is in the right range (Database Property) PS Why Delphi didn't have a DBEditNumeric or EditNumeric component I'll never know.

Re: [DUG] [DCC Error] F2039 Could not create output file 'ShelfGenie.exe'
Glad to help :) Generally speaking, access violation occur when you are trying to access an object that doesn't exist (anymore). Since you get this error when closing the main form, it is very likely the program is trying to access an object that has already been freed (prematurely). You may need to place a breakpoint on the main form's close event and step into the code (F7) as it traverses to each line across the project to identify at which point it crashes. Alternatively, when you are running the application from within the IDE in debugger mode, when the access violation occurs and it'll ask you to break or continue. Just break and view the call stack to see where the error occurred and then hopefully you will be able to identify what object it is trying to access.

Re: [DUG] Variables stored
Actually is Self.Create safe - rather than TMyDialog.Create? I think Jolyon explained it better than me but for me, it means that there is less code that needs to be modified/maintained. Self in the class method will refer the class that the method is being called from. In the case that I have group of dialog boxes with the same standard behaviour, I can define a class method Execute in the base class and use the Self identifier without having to define the Execute class method in each and every descendant class.

If you are going to declare a constant and then use a compiler switch to make it behave like a variable, then be honest and just use a variable!! Typed constants cannot even be used where “normal” constants can be: const ONE: Integer = 1; procedure Foo(aIndex: Integer = ONE); // ERROR: Constant expression expected or: case iValue of ONE: ; // ERROR: Constant expression expected end; Remove the type declaration from the ONE const, and both compile just fine (note that this is independent of the Assigned Typed Constants compiler setting). A typed constant is to all intents and purposes a variable, and might as well be declared as such (note that you can initialise a unit variable as part of it’s declaration): var ONE: Integer = 1; One final comment – Delphi really has no concept of a “global” variable. The highest visibility is “unit variable”. You still have to explicitly “use” a unit to bring it into scope, and if two units declare variables of the same name normal scoping rules apply but you can explicitly qualify a reference using the unit name if you need to override the default scope. Most of the time global/unit variable is close enough that the distinction doesn’t matter, but when it comes to dogma the old rules that “global variables are the spawn of Satan himself” needs to be tempered in Delphi with the fact that they are a bit better “behaved” than the sort of global variable that those ritualistic rules were originally devised for. However, it is still true that the occasions when a unit variable is called for are relatively few, but they should not be simply outlawed for being something they are not.

What we *don't* need is a Delphi (or a VCL) for a Lowest Common Denominator that fits Windows and Mac and Linux and phones and toasters and key-fobs. Totally agree with Jolyon. Initially, I was really looking forward to Delphi for Mac. But the more I think about it, solutions that are not based on the native GUI frameworks for each platform will most likely result in sub-par applications. If I want to design a cross-platform app for both Windows and Mac, then my design decision would be to refactor out all of the non-gui logic into their own units and then build separate user interfaces using the native UI components for each platform. As Jolyon stated, what makes sense/looks good in a Mac application does not necessarily make it appropriate for a Windows application and vice versa. If you want to do a proper job, you will most likely create seperate UI's for each platform. If that, being the case, it makes no sense to aim for that lowest common denominator because in the end you will please neither of your Windows or Mac users. I think Embarcadero's plan to use a common 'VCL will initially satisfy the uninitiated who wants to go cross-platform easily and quickly but will be annoying if you want to create apps that are designed specifically for the platform that they are to be hosted on. I see this as the same problem with the attempt to get existing Delphi applications Unicode-ready. The ideas was to make it easy for existing code to become Unicode but it made it confusing for new apps going forward. I think this will be the same for cross platform development for Delphi using this common VCL approach.

Re: [DUG] Upgrading to XE - Unicode strings questions
Doh! Thanks Jolyon for clearing that misunderstanding on my part. I was aware of the surrogate pair issue but I wrongly assumed that this might have been taken care by the iterator implementation. I guess not. Thanks again! Cheers, Colin On 23 November 2010 13:06, Jolyon Smith jsm...@deltics.co.nz wrote: Colin, the for C in loop and the for i := 1 to Length() loops are functionally identical! The only difference is that the “for in” version incurs the slight overhead of the enumerator framework invoked by the compiler and runtime magic to support that syntax. But in neither case will the loop itself help detect/respond to surrogate pairs (a single “WideChar” is potentially only ½ the data required to form a complete “*character*”). The only way to reduce an iterator over a string to a simple char-wise loop, whether explicit or using enumerators, is to first convert to UTF32, the facilities for which in the Delphi RTL are cough rudimentary, to put it politely. Non-existent may be nearer the mark. The precise mechanics of the loop construct used is not material to that problem. However, just as before Unicode when most people didn’t care and just wrote code that assumed ANSI==ASCII, these days people won’t care and will write code that assumes that Unicode==BMP (Basic Multilingual Plane), ignoring surrogate pairs just as they used to ignore extended ASCII and ANSI characters.

Re: [DUG] unit source code size
Can you refactor your code? See if you can break your classes or methods into smaller segments. Depending upon your class relationship, can you reduce it to one class per unit? If you have such large methods (200 lines seems like is a lot!), you can break them up into smaller methods. If it make sense, you could possibly extract a base class out of your existing class and have that in another unit. Or rather than extracting out a base class, you can make your classes more coherent by redefining them based on their functionality. eg an order class that maintains a list of order items, calculates their totals and taxes and generates a printed invoice can be broken into several smaller (but associated) classes - one for maintaining items, one for calculating totals and taxes and another for printing invoices.

Re: [DUG] Windows 7
Hey Bob, I could probably be totally off-track, but why don't you check the order of the creation of forms.

When I move the dataset and table to the component form and reconnect them to the components on the same form, the project compiles and I can add and delete information and re-compile with no problem.

Re: [DUG] Delphi on Windows Mobile
I guess if you are not planning to market your iPhone app to the wider community via the App Store and just building an enterprise application that is used specifically within a business, then you may be able to getaway with developing with Monotouch. I might just add that I am just speculating and have no real idea as to whether the gatekeepers at Apple will or wont stop this kind of development as well. Regards, Colin On 5 May 2010 14:05, Jolyon Smith jsm...@deltics.co.nz wrote: I'm not sure that the new licensing is an issue for monotouch as they support iPhoneOS 4 presently - I think the licensing is more aimed at Adobe (I'm not sure why Apple hates flash so much). But I'm sure others on this list know more about this than I. The language in the license quite clearly and obviously applies equally to MonoTouch. Novell would have been working on 4.0 support long before the license terms were changed. So of course they announced support for it, they weren't about to throw all that work away. And MonotTouch can support OS 4.0 without violating the license. People can even still use it to develop apps without violating the license. The license only affects whether those apps will then be permitted access to the store. It's like the landlord in your pub... he will happily sell you beer. If on the way home you then get pulled over and arrested for drunk driving, well, that's between you and the law, nothing to do with the landlord. (don't pull too closely at that analogy... landlords typically are limited by the law in some respects, e.g. to not serve intoxicated persons, but someone doesn't have to be intoxicated to be over the drink drive limit). But whole debacle is a bit pointless. The license also already gave Apple the right to deny access to/withdraw any app from the store without reason. By introducing this language I think they are covering their legal backsides against a potential law suit from someone who feels their development language/tool/framework is being specifically and unfairly targeted by Apple. This language gives them plausible cause: The license clearly states... etc etc, so we're sorry, but all those applications written in/for your product willfully violated those terms. You knew that when you started developing/selling/marketing your product to developers. Presently they have Adobe Flash in the public gun-sights - the MonoTouch guys aren't being targeted at present (but neither have Apple said that MonoTouch escapes being covered by the license language). The bottom line is that anyone using MonoTouch to deploy code written in Delphi Prism, C# or any language other than those specifically allowed in the license for iPhone/iPad cannot now complain in the future if they have their app pulled/denied access to the store on the basis of it being a MonoTouch app. They couldn't complain before either of course, but a single developer irked at not being allowed to distribute his app isn't who the license is aimed at... it's aimed at the legal departments of the language/tool/framework/runtime vendors that those developers might choose to use.

Re: [DUG] Need help in format function
I don't remember reading in the original post that Vikas needed the function in a multi-threaded app? In fact, the original FloatToStrF that Vikas used in his original post is the non-threaded version, so I think it is reasonable to assume that he was using it in a single threaded fashion. But thanks for pointing out how useless *Format ( Const Formatting : string; Const Data : array of const) : string; *is for multi-threaded situations.

Re: [DUG] Interbase Blobs in Delphi 2010
Sounds like a Unicode issue. The default string in D2010 is a unicode
string.
Can you use:
IBQuery1.ParamByName('blobby').AsString := 'blah blah blah';
?

Hi All.
I am just working thru converting a D2007 app to D2010.
Its taken me most of the moring to get updated controls, install them,
convert strings etc.etc. but this one has stumpted me.
I am inserting some data into a blob field in Interbase like so (or
similar)
IBQuery1.ParamByName('blobby').AsBlob := 'This is the data to go into the
blob field';
Now interesingly enough, this works fine In D7 and D2007, but D2010 says
[DCC Error] untWebEPortal.pas(2223): E2010 Incompatible types: 'TBytes' and
'string'
I guess I now have to do something else, can someone point me in the right
direction?

Re: [DUG] Interbase Blobs in Delphi 2010
Well alternatively, you can try passing in an AnsiString into your blob
field. I haven't tried it myself but it may be worth a go.

well, the thing is, this IS a blob field not a string field. but I will
give it a try
