hello
replace
 PUSH    _dwBufferCoord
 PUSH   _dwBufferSize
for
 PUSH    dword [_dwBufferCoord]
 PUSH    dword [_dwBufferSize]

ok ?

Well it isn't clear to me which parameter is incorrect. I'm thinking that "smallrect.bottom" and "smallrect.right" should probably be nonzero. Say 10,10? But I dunno.

Best,
Frank

compiling and running on Vista 32bit produces the following output:
C:\X-Asm\X_Template>prnrect2
The operation completed successf
C:\X-Asm\X_Template>

I somehow think this is not the output desired??

Changing the values for smallRect in the above example:
Code: [Select]
_smallRect ISTRUC smallRect
     at smallRect.Left, DW 0
    at smallRect.Top, DW 6
    at smallRect.Right, DW  10
    at smallRect.Bottom, DW 10
IEND

yields the following out put:
Code: [Select]
C:\X-Asm\X_Template>prnrect2
The operation completed successf
C:\X-Asm\X_Template>
A
!?

d
each of the symbols displayed has a different back ground, red,green and yellow. Not sure if this was the intended output? or just a coincidence?
