Hi  
I am using AutoIt inside my ruby script. The purpose for this is so that  
I can check if there is a value, specifically 3432432.exe in a list. I  
can’t figure out why the method ControlListView is not working. Other  
methods are working fine with the AutoItX3 control. Do you know what I  
might be missing? The error is below. Thanks MC

Error:  
in `method\_missing’: ControlListView (WIN32OLERuntimeError)  
OLE error code:0 in   
  
HRESULT error code:0x8002000e  
Invalid number of parameters. from preVolume.rb:70

#snippet  
winVol = WIN32OLE.new(“AutoItX3.Control”)  
winVol.WinWait(“Vol Win”,"",5)  
winVol.ControlListView(“Vol Win”, “”,3,“FindItem”,“3432432.exe”)

The AutoItX3 documentation says:
