Forgot to mention, but as JohnOne said, I am using the DLL directly from the lib folder in my solution.

I did not need to register on the host computer (XP). I did not test on 64bit however, only on Win7 32 and on XP. Both worked without any problems (Win 7 pc has however AutoIt editor installed)

SOLVED! Ok, I made a studpid mistake that took me quite long to figure out. The name of the window is "Untitled - Arta" and is only changed to "AbbeyClone_12072012_205636_deg15.pir - Arta" after the file is saved. The save instruction was after the ControlClick command of the updown control... So statement 'au3.ControlClick("- Arta", "", "[iD:1312]", "LEFT", 1, 10, 10)' now works perfectly (WinTitleMatchMode=2 in my app)

Just "add reference" to the AutoitX.dll and set Embed Interop Types" to FALSE (see properties tab in references). This worked ok for me. In the class where you want to use AutoIt functionality (C# code): AutoItX3Lib.AutoItX3Class au3 = new AutoItX3Lib.AutoItX3Class(); au3.AutoItSetOption("WinTitleMatchMode", 2); au3.WinWaitActive(windowName, "", maxTimeInSec) ...

In VS2010, I needed to set "Embed Interop Types" to FALSE (see properties tab in "references). Otherwise I got a compilation error.

Hi, I am using the AutoItX in a C# application. It works great and I have already automated 99% of the stuff I wanted to do. Now, for some strange reason, I am struggling with the click of a button (In my application, I clicked >100 buttons, and all worked without problems, but for some reason this one is different!? These are some of the statements I already tried: au3.ControlClick("AbbeyClone_12072012_205636_deg15.pir - Arta", "", "[iD:1312]") au3.ControlClick("AbbeyClone_12072012_205636_deg15.pir - Arta", "", "[iD:1312]", "LEFT", 1, 10, 10) // added coordinates because it is a control with 2 buttons for up/down, 10/10 corresponds with the center of the top button au3.ControlClick("AbbeyClone_12072012_205636_deg15.pir - Arta", "", "[CLASS:msctls_updown32; INSTANCE:6]") au3.ControlClick("AbbeyClone_12072012_205636_deg15.pir - Arta", "", "[CLASS:msctls_updown32; INSTANCE:6]", "LEFT", 1, 10, 10) au3.ControlClick("AbbeyClone_12072012_205636_deg15.pir - Arta", "", "[CLASS:msctls_updown32; INSTANCE:6]", "MIDDLE", 1, 10, 10) All do NOT return "1" (and the button is not clicked of course...) Any help would be very much appreciated.
