I once found a tutorial on live templates and they explain how to write them. It looked rather self explanatory if you know the syntax. They are invaluable in using tiOPF and other frameworks where you're doing a lot of inheritance and overriding methods. I have a couple live templates that create whole units which saves a lot of time. -- Warm Regards, Lee ___ Lazarus mailing list Lazarus@lazarus.freepascal.org http://www.lazarus.freepascal.org/mailman/listinfo/lazarus

I use the one for Delphi called CNWizards which has it. Lets say I type tstr, then the suggestion box is displayed automatically and TStrings is highlighted already with TStringList next in the list etc. At that point, all I have to do is hit Tab or Enter and the section is writtent the editor followed by a space so I can keep typing. The CNWizards version has useful settings such as how many characters have to be typed before auto suggestion is invoked. I like it set to three or four characters. I personally like it because it saves time when I have type write type names like TGenericMediatorClass. Instead, I type tge (or more letters) and the list is automatically displayed with the item closest matching what I typed already highlighted. I just hit enter and continue typing. I think open office (text editor) and Word have this same kind of feature. -- Warm Regards, Lee ___ Lazarus mailing list Lazarus@lazarus.freepascal.org http://www.lazarus.freepascal.org/mailman/listinfo/lazarus

Yes, it produces pkZIP compatible files and yes, it uses zlib for compression. .zip file format deals only with overall archive file structure (headers, directories, etc). Each individual file within .zip archive may be compressed using its own method, or even not compressed at all. The most popular compression format used in .zip files is 'deflate', which is handled perfectly well with zlib. The difference with .gz format is only that compressed stream is written without .gz header. Thanks for that, Sergei. I wasn't aware of that and thought that they used incompatible compression algorithms.

The only other option that I saw was apache dso's using the fpWeb framework but that did not turn out too well and I spent quite a long time trying to get apache to load the dso (which it would not) let alone actually running it. I have currently written a large chunk of our application using Powtils for standard CGI applications. I miss object pooling or DB connection pooling a lot. Setting up a connection is very slow compared to many other things, and having to do that on every mouse click is not ideas. Right. Since CGI is a one-off technology, you have to setup and tear down db connections, which (and I could be wrong here) tiOPF takes a bit longer to do than standard TConnect TDataset model and since I use tiOPF as well, I'd prefer not to take a hit like that if I don't have to. I will be investigating alternative options. fpWeb and DSO etc.. I even thought of creating a Application Server application like in a 3-tier app. The CGI apps then communicate to the application server. The app server is the only one that has the actual DB connection. In theory this will work, but I haven't tried a prototype yet. One idea that I had was to use a gateway application, much like they're doing over at ExtPascal. ExtPascal uses FastCGI in one of 2 ways. 1. Gateway App = FastCGI Server. This model is designed for webservers that don't have cgi support. A standard gateway.cgi application takes the actual rqeuest and then communicates with a backend FastCGI (basically TCP/IP) server to fill the request. 2. Stand alone FastCGI server. This is the FastCGI server used in the first model but is used for web servers that have native FastCGI support. In this model the server (apache) just talks to the persistent running FastCGI server directly. There server is pretty well abstracted out of the ExtJS stuff that the project is based on so I may just use their code for ideas. Of course, FastCGI (like apache DSO's) have their drawbacks in terms of being able to actually use them on a shared hosting plan as most providers do not allow you to install DSO's or long running processes like TCP/FastCGI servers. But a nice compromise would be to write a cgi gateway like in ExtPascal with a few minor changes so that my business logic can be the same regardless of whether its standard cgi running on a low traffic Plesk/CPanel account or a dedicated server. Also, Michael van Canneyt has written some articles on Free Pascal/Lazarus and web apps. Maybe if you ask nicely, he can send you those, which might give some hints on how to use fpWeb etc.. :-) Michael? Michael?

Are there any examples for apache shared modules or is it pretty much the same as the CGI? I see they both share the same ancestor datamodule descendant. Are there any tutorials for setting up the apache mod version? I plan to most of the coding with the cgi but again, want to make sure that the apache module version would work as well.

I've been tickering a bit and I need to ask if anyone is using the apache
module
version of fpWeb? I've tried for about an hour and half to get apache2 to run
with a sample module to no avail.
Library mod_test;
{$mode objfpc}{$H+}
Uses
fpWeb,lazweb,httpd,fpApache, web1;
Const
{ The following constant is used to export the module record. It must
always match the name in the LoadModule statement in the apache
configuration file(s). It is case sensitive !}
ModuleName='test';
{ The following constant is used to determine whether the module will
handle a request. It should match the name in the SetHandler statement
in the apache configuration file(s). It is not case sensitive. }
HandlerName=ModuleName;
Var
DefaultModule : module;
{$ifdef unix} public name ModuleName;{$endif unix}
{$ifdef windows}
Exports defaultmodule name ModuleName;
{$endif windows}
{$IFDEF WINDOWS}{$R mod_test.rc}{$ENDIF}
begin
Application.ModuleName:=ModuleName;
Application.HandlerName:=HandlerName;
Application.SetModuleRecord(DefaultModule);
Application.Initialize;
end.
My Apache2 httpd.conf:
LoadModule test modules/mod_test.so
Location /test
SetHandler test-handler
/Location
When trying to start apache, I get:
Syntax error on line 136 of C:/Program Files/Apache
Group/Apache2/conf/httpd.conf:
Cannot load C:/Program Files/Apache Group/Apache2/modules/mod_test.so into
server: The specified module could not be found.
The mod_test.so executable is definitely in the /modules directory of the
Apache
installation. Has anyone had this working or can provide a hint or two?
I'm on Lazarus 927 on Vista.
I'm a little frustrated at this point so I'm going to go for a walk... :)
Thanks,

I have read somewhere that Lars (z505) is quite swamped with paying work (job contracts) at the moment, so powtils is on the back burner for a while.

LCL doesn't belong in a CGI (basically console) application! Also it doubled the size of the CGI application. Yes I tried with SmartLinking and Strip. I simply removed the design time webmodule support (you just assign event handlers anyway with it), which then removed the LCL dependency and everything still worked fine - and I have a *much* smaller CGI executable without GUI requirements.

Well, looking at the code:

lisUserSHomeDirectory, nil, []));
{$ENDIF}
It's illogical. It cannot have this error because it's in a IFDEF, so
you are not using FPC 2.2.0
Go to the command line and run your compiler. It will show his
version. Or easier: fpc -v
FPC is not on my path variable, I must navigate to the directory of the
whatever
fpc version I want to check to do that.
I compile LCL with FPC 2.2.0 and I don't get this error.
How did you install FPC?
See my post response to Maxim just before this reponse.
Also, what operating system are you using?
Vista business ed.
I've tried 2.2.1 which is the same above.
Because your 2.2.1 is old. You need to update it, which will actually
now be 2.2.3
I tried 2.2.3 which I got by downloading a snapshot.
I've tried 2.2.3 which instead says it cannot find the Contnrs unit, which
I've
now idea how that is possible since its sitting right there in the folder
M:\fpc\2.2.3\source\packages\fcl-base\src. I have FPC Source Directory
pointing to M:\fpc\2.2.3\source.
The FPC Source Directory is designed to find the source when you
want to find the declaration of something.
It is *not* designed to build FPC on the fly
You have to build FPC yourself.
contnrs is part of FCL. A standard FPC compilation builds only the
compiler and the RTL.
You now need to build the FCL too. Here is how I build the FCL (in a
batch file):
cd packages
PATH=C:\Programas\lazarus220\fpc\2.2.1\bin\i386-win32
make clean all
COMPILER_UNITTARGETDIR=C:\Programas\lazarus220\fpc\2.2.1\units\arm-wince
cd ..
pause
This apply If you are building the compiler manually.
Don't know, I'll give this a try as well, but just followed Luiz' advise and
commented out the offending portions which he did because he was getting the
same error as well.
Thank you for the in depth reply.

I've tried 2.2.3 which instead says it cannot find the Contnrs unit, which I've now idea how that is possible since its sitting right there in the folder M:\fpc\2.2.3\source\packages\fcl-base\src. I have FPC Source Directory pointing to M:\fpc\2.2.3\source. Now, I haven't used Lazarus in about a month and the only thing I did was write click on my lazarus source folder and tell Tortoise SVN to download the latest sources. Before I did that, I could build my IDE with either 2.2.0 or 2.2.1 of FPC. Now, I can't build it with any of the above. I'm not sure which or even how the configuration could be a problem unless there are more settings to change/set those that I have mentioned above, which are the only ones I've ever changed in the past. How do you recompile your IDE? If you do it from command line then check your PATH environment variable, otherwise setting the properties you mentioned should be enough. A While ago I followed the instructions on the wiki for compiling lazarus from sources on windows. Since then, I would just use tortoise svn to update my sources and recompile from the IDE using the build commands with everything checked to be maked, cleaned and built. This worked up until the last svn update I did a couple days ago. Yes, I understand this. But you needed to change your compiler. In what steps did you try to do it? It seems you made some mistake here. Ah, my fault. I downloaded and installed the latest lazarus snapshot that included 2.2.3. I then copied the fpc directory from that install to another directory on my computer. I then uninstalled the new snapshot. From there, I just updated the paths in my svn lazarus to point to the new fpc binaries and source under Environment Options and tried to rebuild lazarus from there. A bit of a round about way, but I didn't see any pre-built binary downloads for fpc 2.2.3 on the fpc site. BTW, the fpc 2.2.3 doesn't give me the error concerning GetUserDir, at because it doesn't get that far, but bombs almost immediately when trying to rebuild lazarus saying that it cannot find the contnrs unit. -- Warm Regards, Lee ___ Lazarus mailing list Lazarus@lazarus.freepascal.org http://www.lazarus.freepascal.org/mailman/listinfo/lazarus

Hmmm. The last svn that I downloaded, 15156 compiled ok with fpc
2.2.1 so I'm having trouble understanding why I would want to
downgrade from 2.2.1 to 2.2.0...
Lazarus only runs with the released FPC or the current development
version. At the moment: 2.2.0 and 2.2.3.
Mattias
Odd. As I mentioned, I have rebuilt using 2.2.1 but I guess that particular
source must have changed between the last time I updated.
Is there a way to specify an fpc to use for rebuilding lazarus, but use my
newer
one to compile my programs or must I just change the paths manually when I
want
to build lazarus and then set them back?
AFAIK no. It won't work anyway as all modules used by your program
should be compiled by the same compiler version (your program depends on
LCL and Lazarus depends on it too, hence LCL, Lazarus and your program
need the same compiler version).
IMO the best option here is to use 2.2.0 for production software. 2.2.3
can be used too, but there can be some unexpected glitches. Also you can
try 2.2.2rc1. It is newer than 2.2.0 and should be more stable than 2.2.3.
BTW if Lazarus doesn't compile with 2.2.0 then you have found a bug.
Yeah, I get the same error using either FPC.
I'll submit a bug report.
Thank you.

Exactly our issue as well. We have a GUI application designed for kids and need it colourful. We also have a admin GUI application designed for our franchises and needed custom (corporate) colours overall. We also use colour for input validation forms. Most of these worked when we ran under Windows, but not when it's run under Linux. Defeats the purpose of cross platform apps. Our custom drawn toolkit solves all these issues.

LCL-GTK2 does feel slow compared to other non-LCL GTK2 based applications. GTK1 (I've got the Lazarus IDE compiled with in) seems okay. This particular component is one that I wrote that simulates a button. It's derived from TShape and changes its border (pen) color and background (brush) color on mousedown and then changes it back on mouse up. I've noticed it with plain TButton too however. For instance, I have a simple test app that loads a TListView with dummy data in a 50 count loop. Many times you will not see the TButton's down state, the code to load the dummy data will just run. You can get it to work if you are conscious of pressing down and then wait maybe 150-250 ms and then release.

[Lazarus] RESSTRSECTIONS?
I've been trying to get GnuGetText to compile again while I think I got a
little
bit farther, I've run into another snag.
GnuGetText attempts to call ResourceStringTableCount, but the compiler say it
cannot find the method. The method is in ObjPas unit but IFDEF'd like this:
{$ifndef RESSTRSECTIONS}
Function ResourceStringTableCount : Longint;
Function ResourceStringCount(TableIndex : longint) : longint;
Function GetResourceStringName(TableIndex,StringIndex : Longint) :
Ansistring;
Function GetResourceStringHash(TableIndex,StringIndex : Longint) : Longint;
Function GetResourceStringDefaultValue(TableIndex,StringIndex : Longint) :
AnsiString;
Function GetResourceStringCurrentValue(TableIndex,StringIndex : Longint) :
AnsiString;
Function SetResourceStringValue(TableIndex,StringIndex : longint; Value :
Ansistring) : Boolean;
{$endif RESSTRSECTIONS}
I'm sorry that I don't know more about the internals, but where would this
directive get set? I tried explicitly setting it myself like below but it
doesn't seem to get set:
{$DEFINE RESSTRSECTIONS} in the gnuGetText unit, but of course that doesn't
work. Then I thought, maybe it doesn't get set unless there is a
resourcestring
section so I tried adding one as well, but that didn't work either.
I had to move some of the IFDEF's around to get it to compile this far so I
suspect there is problems maybe with the $IFDEF logic in this unit...
Judging from this particular $IDEF:
{$IFDEF VER1_0}
Sorry this code itsn't compatible with your FreePascal version. You must use
1.9.x version minimum.
{$ENDIF}
It doesn't look like the unit has been kept up to date.

[Lazarus] Forms Color on Linux
Hi all, I have a couple of questions. 1. Is is a known limitation of gtk1 that you cannot change the form's color? I've tried to do this, but this (at design time) has no effect. 2. With gkt2, the form's color does change with what it was set to at design time but it I've noticed that there is a bit of transition. In other words, when the form is shown it takes on the default color and then changes so that you can see a splash of white before the color that was set at design time takes effect. Note: I'm trying this in a Virtual Box image so there's not a lot of horsepower there for video. Does anyone else see this behavior?

[Lazarus] Object free itself?
I've never tried this type of thing before, but I have need to have an object free self. After freeing any resource used by the object in it's Destructor, I call inherited destroy and it looks like the inherited destroy methods works, but right afterward, get a sig exception in LCLProc.unit: function TMethodList.Count: integer; begin if Selfnil then Result:=FCount == here else Result:=0; end; Is it even possible to have an object free itself? BTW, I'm trying my hand at creaing an MVC and I need the controller to be able to free itself because it is the object that 1) Creates the View (form) and 2) the Model (object) and mediates between them. When the form is closed, the controller is notified and need to 1) free the form 2) free the model/object and 3) free itself. Otherwise, I guess I must create some kind of manager object/list to free the controller from the outside. Note: If I free the controller object from outside (like putting it in an objectlist and calling ObjectList.clear) there is no exception. Just calling free from the object itself poses the problem. Thanks for input. -- Warm Regards, Lee ___ Lazarus mailing list Lazarus@lazarus.freepascal.org http://www.lazarus.freepascal.org/mailman/listinfo/lazarus

Yes. In fact, it does not matter who frees it. Just make sure, all refences to the object are set to nil.

Create a backtrace. Find out, where something accesses the control after it has been freed. OK, then there must be a something that is still referencing the object somewhere. I'll check.

I tried evaluating LazReport a few months ago and had problems with aggregate functions cause AV's and stalling the program. I thought I'd give it another go with svn rev.15082 and while I won't rule out the fact that I may be doing something wrong, I can't seem to get it to act right for anything but the simplest listing reports without aggregate functions whatsoever. Has anyone used this component for any significant reports? Again, I've never used FreeReport per se, only the commercial FastReport version so I'm assuming that I have at least enough knowledge to build a simple report with aggregates, but my impression thus far is that the component just seems unusable for me. Again, I could be just doing something wrong as I'm sure that there were significant changes between the FreeReport version and FastReport 2x or 3x. I am also a FastReport user: FreeReport is just an early FastReport 2.x version, so if it worked in FastReport 2.x, it should work in FreeReport/lazReport. Agreed. FastReport is an excellent reporting tool and I would like very much to get it to work, but it appears that remains to be seen as of now. It's of course possible that during porting, some bugs were introduced. The Fastreport People told me (back in October) that they planned to port FastReport 4 to Lazarus in Q1 of this year. Since I haven't seen anything yet, I assume that some problems popped up. I'm not altogether surprised because it's not an easy task, given the complexity of FastReport :-) Well that give me an excuse to upgrade, but I am fairly satisfied with FR 3 right now. :) I can imagine that is must be a fairly daunting task! -- Warm Regards, Lee When my company started out, we were really, really, really, really small.

I have not user FreeReports or LazReports yet, so can't comment on them. I wouldn't dismiss Lazarus/Free Pascal that quickly though. ;-) I have a RTF based report engine which might come in handy as well. I use it to report off my tiOPF objects, but it can report from TDataset's as well, or both. You can create custom fields (tags) for use in your reports as well. So you are only limited to what Free Pascal can do! :) The RTF report engine was originally written for Delphi and tiOPF. I ported it to Free Pascal and fpGUI. It should work as-is for Lazarus. I commented out the image support due to fpGUI lacking JPEG support, but that should be fairly straight forward to get working with Lazarus (as it's much closer to how Delphi works). I can email you in private the original and ported RTF engine if you want. It's one unit and a sample application. BTW: I use OpenOffice to view reports and design the rtf report templates. I have even created a OpenOffice macro to convert the generated rtf to pdf before it gets viewed by the user. BTW #2: I still want to have a look at PowerPDF as well. That would be handy for non-Lazarus based applications as well. Hi Graeme, That is the whole point, to use Lazarus/FreePascal! I want freedom of platform! I already know I that can (and am, for that matter) writing the major (front office) portion of my application in Laz/FPC. I'll take a look-see, but I'd rather not have 3rd party requirements for reporting if I can help it. PowerPDF seems pretty tight to me, even is there is no banded report designer. Maybe if you would send me what you have for your rtf engine, I could see how it might be used as a basis for one with PowerPDF. Fortunately, I will not need to start writing reports for quite a while yet so I can wait to see how LaReport shapes up. Just knowing I could use PowerPDF (after playing with it a bit yesterday) is enough for me if LazReport doesn't seem viable by the time I have to start on reporting. Nice to have options. :) BTW, I noticed that the PDF export filter that was written for FreeReport uses PowerPDF for its engine.
