I can't load bitmaps!
For some reason, I can''t load bitmaps from file into a HBITMAP handle! szfilename is a LPCTSTR string, like "testimage.bmp"
Oh what is wrong?!
Does it have something to do with my project''s bitmaps being in the Resource folder? (in Microsoft Visual C++)
//Load the bitmap "szfilename" into the bitmap handle
hbm = (HBITMAP) LoadImage(NULL, szfilename, IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE | LR_DEFAULTSIZE);
if(!hbm) {
return 0; //error that always happens!
}

You may want to explicitly specify your desired height and width, since the LR_DEFAULTSIZE flag "uses the width or height specified by the system metric values for cursors or icons." But you specified it was an IMAGE_BITMAP, not an icon or cursor.

I tried that, but doesn''t stop the errors.

The bitmaps should be in the same folder as your executable. I don''t use MSVC, but I''m confident that this is the problem.

You could provide a little more information to us if you could tell us what GetLastError() is returning after the failure.

Never mind! I got my code to work by loading the bitmap from a resource script using MAKEINTRESOURCE(IDB_BITMAP) in place of szfilename.

damn, I think I got the same problem like you
my bmp file is in the debug folder, so my program should find it
how do I use that Getlasterror() code?
this is how I try to load my bitmap
note that Write2Log() is a function that writes to a log-file so I knew where my program goes wrong
and second note I already used this code in an other game and there it worked fine
also note that I don't get any compile errors
thanx in advance for any help

Hey, aren''t you testing that if hbm returns NULL, it writes "Load image successful" and if it DOES return something, it writes "Load image failed". Seems to me you need to use !=NULL instead of ==NULL :
if((hbm = LoadImage(hInstance,file,IMAGE_BITMAP,
0,0,LR_LOADFROMFILE|LR_CREATEDIBSECTION))!=NULL) {
Write2Log("Load Image Successful");
} else{
Write2Log("Load Image Failed");
}
if((hbm = LoadImage(hInstance,file,IMAGE_BITMAP,
0,0,LR_LOADFROMFILE|LR_CREATEDIBSECTION))!=NULL) {
Write2Log("Load Image Successful");
} else{
Write2Log("Load Image Failed");
}

P.S. How do you get your code to appear in that nice, centered, white box?

could that be my problem? ![](sad.gif)
although I don't think so because the rest of my load bitmap code also fails, so I think it's not loaded well?!?
but thanx anyway, I'll check tonight, who knows
for that nice white box just use this html code
