Need help with DLL and DllCall

[xwinterx]

I am learning C# and trying to make a dll that I can use with an autoit script. I have attached the dll to see if anyone can help me. All it does is return a string value. It works on a console app I made to test it in VS2008, however I get an error that the function is not found in the dll file when I try with autoit. Here is my au3 code:

$dll = DllOpen("ClassLibrary1.dll")

If $dll = -1 Then
    MsgBox(4096, "Error", "Failed to open dll!")
    Exit
EndIf


$info = DllCall($dll, "str", "GetX")

If @error Then
    MsgBox(4096, "Error", "Error: " & @error)
Else
    MsgBox(4096, "Success!", "Return was: " & $info[0])
EndIf


DllClose($dll)
Exit

I am pretty sure it is just my DLL but I don't really know. I may be approaching it wrong.

ClassLibrary1.dll

You can't call methods inside a managed dll from AutoIt.

so then I need to change the DLL to something unmanaged? was my DllCall atleast right? cuz I am just trying to decide if my error was in the AutoIt or in the DLL. I am assuming that it is in the DLL then and I have to change its type somehow. If so, that way I can go look at other sources for help and not clutter these forums.

It is possible to export some managed functions, but it is not too easy:

In the german forum, someone made a script to do that, but i don't know if it works well.

Still, you need to have the .NET-framework installed to use that DLL.
