c# web service trying to call an external using process.Start(

[stephen]

when I try consuming this method the method just hangs, if I look at the
processes I can see that the wscript is running but it just seems to hang.

shouldn't this be fairly trivial calling an external from within a
webservice ?

[WebMethod (Description="C hanges Password calls
Change_Password .vbs",EnableSes sion = true)]

public string ChngPwd()

{

try {

Process proc = new Process();

proc.EnableRais ingEvents=true;

proc.StartInfo. FileName="wscri pt.exe";

proc.StartInfo. Arguments="c:\\ myScript.vbs";

proc.Start();

proc.WaitForExi t();

proc.Dispose();

return "ran change password";

}

catch (Win32Exception e)

{
return e.Message ;

}
}

}

Check the doc on the Process class. You may need one or more of the
following:
proc.StartInfo. WindowStyle =
System.Diagnost ics.ProcessWind owStyle.Hidden;
proc.StartInfo. RedirectStandar dOutput = true;
proc.StartInfo. UseShellExecute = false;

I had the same problem, and my problem was solved by adding:

UseShellExecute = false;

Anyway, please check if you really don't need the shell for the desired processes... in my case I was just launching exe files, so I didn't required any shell service.

Regards.
