    Question bits per pixel

    Now this seems simple enough, but it doesn't seem to work.....

    Code:
    'first surface is created from file into imgDesc

Dim ImageWidth As Long
Dim ImageHeight As Long
Dim ImageBPP As Long

ImageWidth = imgDesc.lWidth 'this works
ImageHeight = imgDesc.lHeight 'this works too
ImageBPP = imgDesc.ddpfPixelFormat.IRGBBitCount 'this always returns 0
    0 bpp?

    did you flag the DDSD_PIXELFORMAT bit on dwFlags before passing the DDSURFACEDESC2
    Use
    writing software in C++ is like driving rivets into steel beam with a toothpick.
    writing haskell makes your life easier:
    reverse (p (6*9)) where p x|x==0=""|True=chr (48+z): p y where (y,z)=divMod x 13
    To throw away OOP for low level languages is myopia, to keep OOP is hyperopia. To throw away OOP for a high level language is insight.

    If I do this:

    Code:
    imgDesc.lFlags = DDSD_CAPS Or DDSD_PIXELFORMAT
    When I come to blit the image using Blt, I get invalid procedure call. But blitting works without DDSD_PIXELFORMAT set.

    I'm totally confused!
