Using Win32 API
Author
Which are the standard for Win32 style
coding for drawing bitmaps and pictures?
My book "Windows Game Programming for Dummies"
doesn't cover it in chapter 5 as it should.
Is there two kinds to use?
BITMAP and HBITMAP?
To use HBITMAP I think one write:
<code>
HBITMAP hBmp = LoadBitmap(hInstance,MAKEINTRESOURCE(IDB_BITMAP_ID));
</code>
Is HBITMAP used for bitmaps in resources?
But how draw/blit it then I don't really know.
Thanks.

Just a hint - I tend to consider "for dummies" books to be crap just on general principles. if you google for LoadBitmap on the microsoft site you get all the information you need, probably a much better resource than the book. You sound as if you don't know if there is another type BITMAP. I would guess not, based on a quick skim-read of the above link(not really sure though).

Thank you. rating++;
I've tried to search msdn for documentation, but never found any good.
But you've found that good documentation that I was looking for.
What did you search on? Edit: Ok. you searched for LoadBitmap

General Tip: If you need info about win32 api method xxx, Google: site:microsoft.com xxx. Works every time.

The HBITMAP LoadBitmap(hInstance,BITMAP_RES_ID); only loads bitmaps from your app's resources.
I need to load bitmaps from file.

Isn't that porn?
See answer here of how to load and display a BMP file

I need to load a bitmap from a FILE *pFile ptr, how todo that?
And how to blit it? The prototype for blitting takes a HDC.
BOOL BitBlt(
HDC hdcDest, // handle to destination DC
int nXDest, // x-coord of destination upper-left corner
int nYDest, // y-coord of destination upper-left corner
int nWidth, // width of destination rectangle
int nHeight, // height of destination rectangle
HDC hdcSrc, // handle to source DC
int nXSrc, // x-coordinate of source upper-left corner
int nYSrc, // y-coordinate of source upper-left corner
DWORD dwRop // raster operation code
);
To convert it seems to be a bit complicated.
BTW, what the difference between BITMAP/HBITMAP and HDC?
The only image format that Win32 API seems to support is just *.bmp, why?

because figuring out how to load other formats is generally pretty trivial. (i don't even understand why it has functions for loading .bmp)
