Using .NET dll

[imdummy]

Hi all, 

I come across a problem in using .NET dll. I have tried with DllCall and ObjCreate, but it doesnt work. My question is : 

1. Do I need to add anything inside the .NET dll in order to make autoIT script know it is a dll? 

2. Am I using objCreate correctly? 

I have tried with: 

FileInstall("xxx.dll",@SystemDir&"\xxx.dll",0)
RunWait(@ComSpec & " /c regsvr32 /s xxx.dll",@SystemDir,@SW_HIDE)
$theLib=ObjCreate("xxx.theClass")
$theLib.theFunction(“ArgumentString1”, “ArgumentString2”)

Thanks a lot!
