Might be off-topic, but please don't mix C++ templates with Java Generics. They are completely different things (although they might offer the same possibilities at first glance). There is no such thing like C++ templates in the Java language.

there must be an error, as far as I understand, since there are 4 arguments in the prototype, and 5 in the calling line. No, it isn't, since the prototype has nothing to do with the actual call here. Here, the function "sqlite3_exec" is called, which has its prototype declared in sqlite3.h, not in ...

Well, the first thing defines a function named "callback" with a return type of int. The "static" in this case means that it is module-local, or only visible in this particular object file (it can neither be used from other object files, nor declared "extern" in any header). void* NotUsed is a param...

You should not set wxSTD_USE_IOSTREAM manually. You have to configure wxWidgets (before compilation) to use iostreams so wxWidgets sets wxSTD_USE_IOSTREAM itself. If you define wxSTD_USE_IOSTREAM for your application, but not when compiling wxWidgets, your application "assumes" that the iostreams me...

Yet another C++ IDE (tm)? ;)

I very much like the CodeBlocks IDE, which has a rich plugin API already, but its wx designer could need a little more work. So wouldn't you rather contribute to one of the existing projects, instead of founding even another one? ;)

Usually Linux/UNIX applications should honor the LANG setting. Try before starting emacs (and if that works, set it globally in for example /etc/profile)

Since I didn't find this one answered yet: MyStruct *a = new MyStruct(); void *p = (void *) a; delete p; Will this free the correct amount of memory? Yes, this will free the correct amount of memory (at least on most implementations I know, not sure if this is even standards-conformant), BUT the des...

Thank you for your reply. We have ported our application to use XRC resources as well by now. Luckily we are just at the beginning, so the work was done quickly ;)

Since this is not a solution, but more of a workaround, I won't mark this as solved yet.

I guess one of your wxWidget libraries is a unicode build and one isn't. You should make sure that both are configured equally (--enable-unicode or --disable-unicode). And you could check if there are any character set conversions when transferring the source files (e.g. via FTP). If you don't want ...

wxMenuItem::SetBitmap[s] after wxMenu::Append - no effect

Hello everyone, I am trying to add a bitmap to some menu items after the menu has been built, which doesn't seem to have any effect. That means the item just doesn't show any image next to it. This happens with wxMSW and wxGTK. The reason I'm doing this is because we use wxFormBuilder to generate C+...
