Assume

[bomz]

What is the difference in using directive ASSUME inside DLL. I make apllication - it's work, but when I make dll using this code mistake occurs: Invalid use of assume.

assume edx:PTR CWPSTRUCT
      .if [edx].message == WM_INITDIALOG

change to

add edx, 8
      .if dword ptr[edx] == WM_INITDIALOG

Probably missing an include somewhere. MASM should not care where the code ends up, it is just building object files, the linker gets to package it in an executable form.

Code Select Expand

.if dword ptr[edx+8] == WM_INITDIALOG

Probably missing an include somewhere.

for training I get "Simple dll" from masm32 examples, and add strings
   assume edx:PTR CWPSTRUCT
   assume edx:nothing
The same result
