Question

I´m trying to run an old .NET application from an ASP.NET website. After reading the web and Stackoverflow (for similar problem) I come to the following code.
The Problem is that I get always an error code (I am using administrator account
just to testing purposes). If I run the exe manually it works ok.

private void Execute(string sPath)
{
    System.Diagnostics.Process proc = new System.Diagnostics.Process();
    proc.StartInfo.UserName = "administrador";
    string pass = ".............";

    System.Security.SecureString secret = new System.Security.SecureString();
    foreach (char c in pass) secret.AppendChar(c);

    proc.StartInfo.Password = secret;
    proc.StartInfo.WorkingDirectory = ConfigurationManager.AppSettings["WORKINGDIRECTORY"].ToString();
    proc.StartInfo.RedirectStandardOutput = true;
    proc.StartInfo.RedirectStandardError = true;
    proc.StartInfo.UseShellExecute = false;
    proc.StartInfo.FileName = sPath;
    proc.Start();
    proc.WaitForExit();
    string result = proc.StandardOutput.ReadToEnd();
    Response.Write(result + " - "  + proc.ExitCode);
    proc.Close();
}

}

The exitcode I get is: -1066598274
Result variable is empty.
No exception is thrown
I am using Windows 2008 with IIS 7.0

Thanks in advance,

You may need to set the proc.StartInfo.LoadUserProfile property to true so the administrator’s user profile stuff is loaded into the registry (AFAIK this does not happen by default).

Also, it might be educational to run a ‘hello world’ program to see if the problem is with actaully creating the process or if the process itself is having problems running in the context it’s given.

Finally, as a step in trying to narrow down where the problem might be, you might want to run the ASP.NET process itself with admin or system credentials to see if something in the permissions of the account the ASP.NET instance is running under is part of the problem (but please do this only for troubleshooting).
