Unable to execute autoIt scripts

[anky]

i am using selenium RC and writing selenium scripts in C# code. I tried to execute autoIt scripts for uploading a file within the C# code but as the debugger comes to autoIt scripts it stucks there only .It gives me no error message .I also tried to run the autoIt scripts .exe file but same is happening .

The code i am using

selenium.Click("Uploader1__Insert");//This code of line works

//This is not working

auto.WinActivate("Choose File to Upload", "Files of &type");

auto.ControlSetText("[CLASS:Edit;INSTANCE:1}", "", "1148",Filename);

auto.ControlClick("[CLASS:Button;INSTANCE:2]", "&Open","1","",1,474,328);
