Hi, tmplinshi, how do I handle ? I can see that AutoHotkey_H lists its license on the github page, and found a program or two that use the DLL, but I don't find a library MinHook.ahk anywhere.
Edit: :facepalm: Wow. I don't know how much more obvious it could have been. :facepalm:
Sorry.
Regards,

Edit: That's really classy, tmplinshi, thank you. That will doubtless come in handy. I had to pull _Struct.ahk and sizeof.ahk out of the Lib folder because I already had them in my main Lib folder. Everything works great, ex. 3 works with AHK_H 1.1.29.01 v002.
Thanks again!

Update to v1.1 (2018-8-16)

  • The module dll will now unload when the hook removed. (Except for standard DLL - User32.dll, Kernel32.dll, ComCtl32.dll, or Gdi32.dll)
  • Added more directories to search for MinHook.dll. You can place Minhook.dll in one of the following directories:
    • WorkingDir
    • WorkingDir\MinHook\x32 and/or WorkingDir\MinHook\x64
    • Minhook.ahk Directory
    • Minhook.ahk Directory\MinHook\x32 and/or Minhook.ahk Directory\MinHook\x64

Hi tmplinshi, This is a very useful script! thanks for sharing! :wave:

I think Example2 needs to modify one line (Otherwise I can't see the effect.):

Example2 - GetOpenFileNameW.ahk
return DllCall(hook1.original, "ptr", ofn), hook1 := ""

But then a window will popup, which was the Example2 trying to avoid. :)
