Problem with x64 import

[Yuri]

I want to use Get/SetWindowLongPtr in my 64-bit program, but GoLink doesn't find them in User32.dll. I guess that's because GoLink is a 32-bit process and the system (Win7/64) gives it a 32-bit version of the DLL, which does not export those functions.

I have tried putting the x64 DLL in the project folder, and this satisfied GoLink, but the program built this way crashes the system to the blue screen if I don't remove the DLL afterwards, and if I do, it still doesn't work because CreateWindowEx fails to create the window.

Is there any workaround for this problem? ::)

Hi Yuri,

I've found this problem too, I'll try to find a workaround.

Hi Yuri,

Try adding the following workaround to your code:

Code Select Expand

SetWindowLongPtrA FRAME hWnd,nIndex,dwNewLong
LOCAL pFunc:Q
invoke GetModuleHandle,A"User32.dll"
invoke GetProcAddress,eax,A"SetWindowLongPtrA"
mov [pFunc],rax
invoke [pFunc],[hWnd],[nIndex],[dwNewLong]
ret
endf

SetWindowLongPtrW FRAME hWnd,nIndex,dwNewLong
LOCAL pFunc:Q
invoke GetModuleHandle,A"User32.dll"
invoke GetProcAddress,eax,A"SetWindowLongPtrW"
mov [pFunc],rax
invoke [pFunc],[hWnd],[nIndex],[dwNewLong]
ret
endf

Let me know if it works.

Thanks, Edgar, it works great. :thumbu I can't believe I forgot of GetProcAddress. Those blue screens obviously confused my mind, I've never seen so many. :bdg
