Re: Problem with message handling
Thanks Henry! I think using messages is simpler and right for me. Gabor Henry Vermaak írta: hi gabor the "event" function is there so you can give the handle to your event (which you get from CreateEvent). then you can create a thread that blocks on this event with one of the wait functions (WaitForSingleObject, for instance). when the reader receives a scan, it will set the event and your thread will resume and process the scan buffer. now this method is also platform specific, since the event functions are in the windows unit. can anyone comment on this for linux? my hunch is that a similar thing must exist... henry _ To unsubscribe: mail [EMAIL PROTECTED] with "unsubscribe" as the Subject archives at http://www.lazarus.freepascal.org/mailarchives
Re: Problem with message handling
I am developing an application for a mobil computer with an integrated barcode scanner which is running WinCE. The API presents two solutions.

[lazarus] Cannot initialize a form from OnShow
Hi,
The problem appear under WinCE. I tried with Lazarus SVN 10209 and FPC
SVN 5191 and 5370.
Create a new application, put a label and a listbox on the form, and
write the following lines into the form's OnShow event.
Label1.Caption:='xxx';
ListBox1.Items.Add('yyy');
Run the application and see, the label's caption not changed and the
listbox is empty.

Re: [lazarus] The compiler don't eat this. Why???
Hi Alexandre! I quoted the FPC's Reference because I think Felipe is wrong. You understood this. But now I'm completely confused.

Re: [lazarus] The compiler don't eat this. Why???
From FPC's Reference Guide: Private All fields and methods that are in a private block, can only be accessed in the module (i.e. unit) that contains the class definition. They can be accessed from inside the classes’ methods or from outside them (e.g. from other classes’ methods) Protected Is the same as Private, except that the members of a Protected section are also accessible to descendent types, even if they are implemented in other modules. Public sections are always accessible. Published Is the same as a Public section, but the compiler generates also type information that is needed for automatic streaming of these classes. Fields defined in a published section must be of class type. Array properties cannot be in a published section. *** Gabor _ To unsubscribe: mail [EMAIL PROTECTED] with "unsubscribe" as the Subject archives at http://www.lazarus.freepascal.org/mailarchives

[lazarus] IDE don't unload/reset debugger after project execution
Hi! I wrote a very small test application for testing UIB. If I run the project first time everything is fine, but if run it again I get an "EUIBError" message. If I reset the debugger from Run menu between executions the program is start properly. My question is: why the gdb.exe is still in memory after the program execution is stopped. And an another thing. If I create a new empty project and run from the IDE, and exit from it, and run and exit.. The gdb.exe is still in the memory and eat more and more space. After I executed anything gdb is loaded until I reset manually or exit from IDE. Are above things bugs or features? I use Win XP Prof SP2 and Lazarus 0.9.16. Thanks for the answers.

[lazarus] Unit output directory vs Target file name
Hi, If I create a new project, set the 'Unit output directory' in Project/Compiler options in example to 'C:\Devel\Bin\Unit' the generated files(.o;.ppu;.compiled;.exe) placed into the 'C:\Devel\Bin\Unit' directory. It's correct, I think. But if I set the 'Target file name' in Project options too eg. to 'C:\Devel\Bin\project1.exe' only the '.compiled' file placed into the 'Unit output directory' and the other files placed into the 'C:\Devel\Bin'. This is a feature or a bug? I tested on Windows XP Prof SP2 with SVN Revision 8910.

[lazarus] Debugger anomaly
Hi! I hope somebody understand my bla-bla. My native language is Hungarian (and Pascal ;-) ). I reported a bug previously with ID 1699. Yesterday I think eliminate that by myself. I don't debug Lazarus never before. Installed actual snapshot build, but debugger not working in it. Next. Installed FPC 2.0.2 and exported Lazarus sources from SVN. After builded, run and configured the environment and debugger options. (Compiler path, FPC source, Make path, Debugger type and path set to the FPC's proper directories) But debugger's approach is was same. I played with the problem many hours and keep on today. Today's snapshot revision is 8893. Debugger not working in it neither. Fetched the same revision's sources from SVN, builded, started, configured BUT then debugger path is set to the snapshot's debugger directory. And debugger working, but only if I set a breakpoint, 'Run to cursor' not working. Now I have a """working""" debugger, I think. I went back to the original problem debug Lazarus. I found the lazarus.lpi file in the ide directory. I think this is the starting point of the debugging mission. BUT. If i put a breakpoint on first line the debugger walk above. If i put in the second line the debugger working normal and program stop and waiting for me. And the 'Run to cursor' working too in lazarus.lpi but only from the second line after main begin. But not in every case. I got some AV-s, Debugger error etc. I'd like eliminate bugs from Lazarus in the future not just discovered by me, but the debugger in this state is unusable in my opinion. A small observation. GDB version in FPC distribution is 6.2.1 (cygwin) and in Lazarus 6.0 (mingw). In FPC IDE the GDB is working properly. Why not working with Lazarus because the compiler is same?
