Can't access DLL function

Recommended Posts

likehu

Hello,

I have compiled a reference DLL in VS 2015 Community and this  DLL works fine with project for which it is used. There is an interface from which u can access functions in DLL.

Developers stated that this DLL is almost universal and can be used with any language with minor changes.

I am trying to access its function from Autoit script and got an error 3, after calling DLLCall - "function" not found in the DLL file.

Please have a quick look, I feel I miss something in C++ library with exporting functions and I do not know what to add as I am new to C++.

Thank you.

Source files and script also attached.

 

Here is my script.

Local $dll = DllOpen("C:\Users\Home\Desktop\dll\user.dll")
ConsoleWrite("$dll handle = " & $dll & @CRLF)   ;$dll handle = 1

Local $result = DllCall($dll, "double:cdecl", "ProcessQuery", "str", "dll$mynumber")
If @error > 0 Then ConsoleWrite("Error: " & @error & @CRLF)    ;Error = 3

If IsArray($result) Then
    ConsoleWrite("Array returned!" & @CRLF & "dll$mynumber: " & result[1])
Else
    ConsoleWrite("$result is not array. : " & $result  & @CRLF)  ;$result = 0
EndIf

DllClose($dll)

And here is dll source. As I understand, function "ProcessQuery" exported with help of DLL_IMPLEMENTS

user.h

      Hey There!
       
      So, what i need to do is an app that can read text in a image (I.e. a png that has text saying "This is a png" and return the text to a variable)
      I'm pretty much a newbie on AutoIt, my purpose is doing that but i don't know any function that can

      Any help is much appreciated

      I have a script that just adds some keyboard shortcuts for things like displaying the current song and artist, moving the window to the side so it won't pop up in my way, and play/pause, next song, previous song (these are the only 3 to still work since they don't need the window handle.)
      In some update recently, Spotify's window class swapped from "[CLASS:SpotifyMainWindow]" to "[CLASS:Chrome_WidgetWin_0]". Using the new class in my controls doesn't seem to work, I've tried getting the window handle from the process handle (_GetHwndFromPID($PID)) but that seems to fail as well.
      Does anybody have some idea of a way I could get this script working again?
       
      edit: seems like discord has the same window class name, so could be some issue with this? Still not sure of a way to solve the issue though, I added a function to get the handle of the active window and can just use that now, but it was able to find it on its own before on spotify startup or script startup which would be preferred.
       
      Thanks!
