>BOOL GetBitmapDimensionEX(hBitmap, lpDimension)
>My feeble attempts at this returned entry point errors. Any help appreciated. I am trying to get the pixel width and height of a BMP file.

Using CLSHeap:

SET PROC TO CLSHEAP ADDITIVE
DECLARE SHORT GetBitmapDimensionEx IN GDI32 ;
  INTEGER hBitMap, ;
  STRING @ lpDIMENSION
DECLARE INTEGER GetLastError IN Win32API
cDimensionStruc = REPL(CHR(0),8)
IF GetBitmapDimensionEx(nhBitMap, @cDimensionStruc) # 0
   nXSize = DWORDToNum(LEFT(cDimensionStruc,4))
   nYSize = DWORDToNum(RIGHT(cDimensionStruc,4))
ELSE
   ? 'Error: ' + TRANSFORM(GetLastError())
ENDIF

You'd have gotten nhBitmap as a return value from calling LoadImage() or some other function/object would need to provide it. LoadImage would look something like:

DECLARE INTEGER LoadImage IN GDI32 ;
INTEGER hInstance, ;
STRING @ lpszName, ;
INTEGER uType, ;
INTEGER cXDesired, ;
INTEGER cYDesired, ;
INTEGER fuLoad
nhBitMap = LoadImage(0,name of bitmap file,0,0,0,0x50)

but could vary considerably from this
