I'm a little confused. I found this: http://msdn.microsoft.com/library/default..../usingmenus.asp
And in the link it does this.
I was trying to do a similar thing in my own code.
HFONT GetAFont(int fnFont)
static LOGFONT lf; // structure for font information
// Get a handle to the ANSI fixed-pitch font, and copy
// information about the font to a LOGFONT structure.
// Set the font attributes, as appropriate.
if (fnFont == BOLD)
lf.lfWeight = FW_BOLD;
lf.lfWeight = FW_NORMAL;
lf.lfItalic = (fnFont == ITALIC);
lf.lfItalic = (fnFont == ULINE);
// Create the font, and then return its handle.
return CreateFont(lf.lfHeight, lf.lfWidth,
lf.lfEscapement, lf.lfOrientation, lf.lfWeight,
lf.lfItalic, lf.lfUnderline, lf.lfStrikeOut, lf.lfCharSet,
lf.lfOutPrecision, lf.lfClipPrecision, lf.lfQuality,
Doesn't do anything. But that's because, hey, it crashes! Before it hits the break, it calls some procedure that um, does some wierd stuff, and then crashes I think with an unhandled exception (that may have been raised in this procedure). Disassembly ends up like this yo.
hFont = ::CreateFontIndirect(&lFont);
That CALL Dialog_T.004013CC there at the end does it. Um. Yeah, that CALL is made unconditionally, and I can't understand it. But the wierd part is, after being all mystified by the fact that it was crashing, I made my LOGFONT structure static, like in MSDN's code, and it did not crash. In fact, the disassembly does not contain that last call.

See, not there. So, my question is:
00401166 . 6A 40 PUSH 40
00401168 . 68 94814000 PUSH Dialog_T.00408194
0040116D . 68 DCAC4000 PUSH Dialog_T.0040ACDC
00401172 . E8 04020000 CALL Dialog_T.0040137B
00401177 . 83C4 0C ADD ESP,0C
0040117A . 68 C0AC4000 PUSH Dialog_T.0040ACC0
0040117F . FF15 04804000 CALL DWORD PTR DS:[<&GDI32.CreateFontInd>
00401185 . 33C0 XOR EAX,EAX
00401187 . 83C4 10 ADD ESP,10
0040118A . C2 1000 RETN 10
Why does my LOGFONT structure have to be static, and if possible, why did it crash in the first place? Nothing in the CreateFontIndirect/LOGFONT documentation about such craziness. All replies appreciated.
