Here's some code I just wrote yesterday that creates a wxEVT_COMMAND_CHOICE_SELECTED // set first choice and force a wxChoiceEvent m_choiceFreqRange->SetSelection (0); wxCommandEvent fakeEvent (wxEVT_COMMAND_CHOICE_SELECTED, ID_CHOICE_FREQ_RANGE); fakeEvent.SetEventObject (m_choiceFreqRange); fakeEv...

We know that unix use '\n' and windows use '\r\n'. It doesn't matter how other applications interpret this. Not true. That distinction is not dictated by the OS. It is determined by the programs that read and write text files. There is no hard and fast rule on an operating system as to what constit...

I find that my use of things like color/colour and gray/grey always depends on whether I've been recently reading stuff by American or English authors. It filters into the brain and becomes the "right" way to spell this word.

I have tried the Distroy function but it does not close the application properly... I get a link error when I try to compile the application again Destroy does work. I've used it to close an application calling it from the handler for the wxCloseEvent of the main frame window. It closes the window ...

is the debug version of new used when you #define _CRTDBG_MAP_ALLOC or am I way off base? The problem with using just that macro is that the file and line numbers aren't very useful (the source code file that maps new to malloc is what shows up). You'll need something like what MFC does: // from af...

sudden thought - make sure you are using the debug version of new for your allocations. The debug version is what logs the file and line numbers for reporting.

By normal mem dump stuff I mean the hex code and how many bytes, but no line/file information. Using these crt flags, should I expect line/file information in the output window? Depends on how the files were compiled, same as with non-wx apps. I don't remember off-hand which switches control what a...

So I included the crtdbg.h at the top of my APPs cpp. and then in the OnExit function of my app i included the call to crtDumpMemoryLeaks(), but it's not giving me anything extra in the output window. just the normal mem dump stuff. am i forgetting to add something? You don't mention it, so I'm goi...

Now is that in conjunction with the visual leak detector, or is that independent of that? That was added so that the "in-house" memory leak detection of Visual Studio via its debug CRT libraries would see and report memory leaks in my code as opposed to the wx code. This is the report that shows up...

When debugging my wx apps with Visual Studio, I found that I needed to add _CrtSetDbgFlag (_CrtSetDbgFlag (_CRTDBG_REPORT_FLAG) | _CRTDBG_LEAK_CHECK_DF); to my app's OnInit to get VS to report the memory leaks in my app. Without this, my wx leaks were reported but not my own home-grown leaks. Judy

I already posted the code from the DLL InitInstance (called at DLL load) and ExitInstance (called at DLL unload). There is nothing else related to wx ininitalization in the DLL source code. Please note that my DLL does not contain GUI code. Also, my DLL exports C style functions. app.h class CMyApp ...

I have exactly the same situation as you - a wx DLL that must be callable from both non-wx and wx applications. As you've discovered, if a wx app statically links with a wx DLL, it crashes. If a wx app dynamically links with a wx DLL, it leaks memory. My solution is the following: The non-wx app can...

%% is correct. This code

Code: Select all

    wxString str = wxString::Format ("testing %% in a string");
    wxMessageDialog dlg (NULL, str, "title", wxOK | wxICON_INFORMATION);
    dlg.ShowModal ();
produces a message box containing testing % in a string
