Ok but my problem is a bit different. For example:
By using a database is very important do not execute the entire function if a query goes bad.
Is there a way to emit a own exception if I want?

How can I use exceptions?
If I use these lines of code
ad "throws" line the program goes to crash.

Hi everybody. Some years ago I used wxPack + MinGW TDM + Codeblocks for developing with wxWidgets. Now I have to modify the program. I see that the wxPack is not updated and how to bring up a wxWidgets developing machine is not immediate. Which are the packages to use knowing that I use: Windows Xp ...

Does that mean that it crashes always on some systems and never on others? Yes, it is. Very unlikely, as there is only one active thread. Or do you have any secondary threads running? No no, never other thread. How many lines are you usually adding in this piece of code? One or two. Try wxSleep() a...

Incomprensible crash on some pc. My program goes to crash on some pc and not on others. The behaviour is very strange and the workaround too. The case is about a wxGrid and a way to insert new lines. Look to these lines (In particolar look at the numerated rows): If I comment the row 1 (wxMessageDia...

If you want and if you have time to spend I can build a virtual machine with all necessary to simulate the crash. I can then send you a userid - password to login and verify the program or I can send you the sources of the program. The program uses a PostgreSQL database to run. If you want do debug ...

I use gdb (ver 7) on Codeblocks. The version of the MinGW compiler is 4.4.1 tdm_dw2-05 but the behaviour happens also with MinGW distribuited with Codeblocks.
See the two attached screenshots.

Yes, you are right. How I have just explained I use gdb for debug. I have simulated an error to verify that the debugger works fine But it does not detect the error that happens only in one pc but not on the other. In this case it returns only this error: "Program receive signal SIGSEGV, segmen...

I tryed the debug mode on two pcs, on a laptop and on a desktop. On the desktop the program works fine but on the laptop I obtain the message: "Program receive signal SIGSEGV, segmentation fault.".

When I run debug appears the attached popup:
What it mean?

And then how do you think about? Do you think that I have link a badly library or do you think that I have an error in my code?

When I try do build a project in debug mode I obtain thi error: multiple definition of wxString ||=== wxTrazioni, Debug ===| C:\SourceCode\Libraries\wxWidgets2.8\lib\gcc_lib\libwxbase28ud.a(baselib_string.o):C:\devel\libraries\wxWidgets2.8.9\build\msw\..\..\src\common\string.cpp|1025|multiple defini...

I do not know what happens in some PC but this line: wxTCCostoManutenzioni->SetValue(DoubleToStr(parent->gestionedatabase->GetCostoManutenzioni(indice->id_mezzo), 2)+ SPAZIOEURO); // Baco!!! does not work but these wxString Riga= DoubleToStr(parent->gestionedatabase->GetCostoManutenzioni(indice->id_...

Sometimes, in a few Windows computers, the wxString concatenation produces the crash of the program.
This feature is describes here: http://trac.wxwidgets.org/ticket/4789
Why this bug is not been never corrected?

I have followed this tutorial http://wiki.wxwidgets.org/Custom_Events#Creating_a_Custom_Event_-_Method_4 to write my custom event. This is my header file: #include "wx/wx.h" DECLARE_EVENT_TYPE( MyFooCommandEvent, -1 ) // Could have been DECLARE_EVENT_TYPE( MyFooCommandEvent, -1 ) // Not ne...
