transparent background for rendering text in win32 api

Recommended Posts

Hey all. There is some function in pure win32 API that will make the background transparent when you render text with the TextOut() function. I can't remember it off the top of my head, and MSDN is kind of hard to search through for a relatively trivial function like that. Can anybody remember what it is? Thanks a bunch.

I think so... yeah. I can't test it though, as on full recompile my entire program is suddenly crashing! Arrgh. I have no idea what the problem is, but thanks - I'm pretty sure that's what I needed. Awesome.

Is it crashing when you are recompiling the program or crashing when you execute your newly compiled program?

Try the following inserted after every Win32 API function call to help isolate the problem.

char buffer[256];
FormatMessage(FORMAT_MESSAGE_FROM_SYSTEM,0,GetLastError(),MAKELANGID(LANG_NEUTRAL,SUBLANG_DEFAULT),buffer,256,0);
MessageBox(hwnd,buffer,"Error",MB_OK|MB_ICONERROR);

Is "SetBkMode((HDC)wparam, OPAQUE);" what you are looking for?
Right function, but he wants TRANSPARENT, not OPAQUE.

Ah, my fault. I copied and pasted it out of my own application; I should have just deleted all but the function's name. [looksaround]
