Help with DLLCall

[Shark007]

Could someone help me with a DLLCall?

This dll should return one of the following integers depending on your speaker configuration.

mono = 0

headPhone = 17

stereo = 1

front 3ch = 2

quadro = 12

5.0 = 6

5.1 = 13

7.1 = 24

If FileExists(@ScriptDir & '\SpkCfg.dll') Then
    $a = DllCall(@ScriptDir & '\SpkCfg.dll', "int", "getSpeakerConfig")
    If @error Then
        MsgBox(0, "ERROR", "error message = " & @error)
    Else
        MsgBox(0, "SPEAKER", "The result is " & $a)
    EndIf
Else
    MsgBox(0, "ERROR", "file not found")
EndIf

I'm quite new to using dllcall so your assistance would be very appreciated.

SpkCfg.dll

DllCall returns an array if successful.

So,

MsgBox(0, "SPEAKER", "The result is " & $a)

should be

MsgBox(0, "SPEAKER", "The result is " & $a[0])

I still get error message 1, unable to use the DLL file

I assume my DLLCall is poorly formatted, but really do not know.

This is what I cannot get past.

Where did this DLL come from? Is there a link to the interface specification? Documentation?

[Shark007]

The dll is taken from the ffdshow inno setup.

The only documentation I could find was through the ffdshow SVN repository.

And you successfully used it in a test under VB, or VC++, or what?

This doesn't sound much like an AutoIt issue.

I see nothing particularly wrong.

Are you sure SpkCfg.dll in script's dir is the one that you attached?

I did not claim autoit had an issue. I am trying to use the dll. I have the issue.

Yes, the dll was extracted from the latest ffdshow tryouts inno setup installer.

ok, i found my problem. I wasnt paying attention to architecture.

I am working on an x64 system, and it was compiling an x64 executable with a 32bit dll.

All is fine. thanks for the assistance.
