Run vbscript from C# Web App.

Have you tried not using a securestring and just a string?

Yes.  I get a build error:  "Cannot implicitly convert type 'string' to 'System.Security.SecureString"

If I comment out the code for the username, domain and password  I get the error:
"The specified executable is not a valid Win32 application.".  I realize that trying to run a .vbs is not an .exe.  I can tell the filename to be "sqlplus.exe" and I will see in the task Manager that SQLPlus.exe is running with the ASPNet account; however, all the code in my .vbs would have to be recreated.    I am running this in Studio 2005 on Windows XP Professional SP2.

Try executing it like this....


process.Start(@"C:\WINDOWS\System32\WScript.exe " + "\"" + @"D:\Projects\Pub\WebServices\MoHuntEdWebSvc\SCRIPTFILES\CreateFTPStudentFile.vbs" + "\"");

New Day...  I'm trying again....
Did as you last suggested.  Compiled fine.  Now get an error: "The system cannot find the file specified".

I checked at the WScript.exe is at the location as well as the ...vbs file.    I have ran this both in Studio and from a browser using localhost.

Any more suggestions?

try this...

process.Start(@"C:\WINDOWS\System32\WScript.exe " + @"D:\Projects\Pub\WebServices\MoHuntEdWebSvc\SCRIPTFILES\CreateFTPStudentFile.vbs" );

Also, lets try to determine which file it can't find.   can you run it without the vbs file as a parameter  so just this:

process.Start(@"C:\Windows\System32\WScript.exe");  

See if that blows up.  If it doesn't then maybe there is a problem with the other file.  I modified the first string above to remove some quotes that aren't needed since you don't have any spaces in your text.

When I just use process.Start(@"C:\Windows\System32\WScript.exe");    error during compile "Static member 'System.Diagnostics.Process.String(string)' cannot be accessed with an instance reference; quailify it with a type name instead.  So I then tried System.Diagnostics.Process.Start(@"C:\WINDOWS\System32\Wscript.exe");  and the application compiled and ran without errors.

So I then tried: System.Diagnostics.Process.Start(@"C:\WINDOWS\System32\WScript.exe " + @"D:\Projects\Pub\WebServices\MoHuntEdWebSvc\SCRIPTFILES\CreateFTPStudentFile.vbs" );  and I get the error of "The system cannot find the file specified."

I have also tried this:  
Process process = new Process();
               process.StartInfo.WorkingDirectory = @"D:\Projects\Pub\WebServices\MoHuntEdWebSvc\SCRIPTFILES";
                process.StartInfo.FileName = @"cscript.exe";
                process.StartInfo.UseShellExecute = false;
                process.StartInfo.CreateNoWindow = true;
                process.StartInfo.Arguments = "D:\\Projects\\Pub\\WebServices\\MoHuntEdWebSvc\\SCRIPTFILES\\CreateFTPStudentFile.vbs";
                process.StartInfo.Domain = "mydomain";
                process.StartInfo.UserName = "myuserid";
                _password = "mypassword";
                process.StartInfo.Password = new System.Security.SecureString();
                foreach (char c in _password)
                {
                    process.StartInfo.Password.AppendChar(c);
                  }
               
                    process.Start();
 
RESULTS:  a window comes up with error:  cscript.exe - application Error
 The application failed to initialize properly (0xc0000142). Click on OK to terminate the application

If I go to the Run command prompt and type in:
cscript.exe D:\Projects\Pub\WebServices\MoHuntEdWebSvc\SCRIPTFILES\CreateFTPStudentFile.vbs
the file will run and produce the results as expected.


I really appreciate your time and help.

What if you change the file in your last example to WScript instead of cscript?  Also,  what happens if you UseShellExecute = true?

Try not setting the working directory either.   maybe that is throwing off your full D path in the arguments

If I set UseShellExecute = true, compiles, but throws error in the try/catch on the process.start.
The Process object must have the UseShellExecute property set to false in order to start a process as a user

so I took off the working directory setting.   My code now looks like this:
Process process = new Process();
                process.StartInfo.FileName = @"Wscript.exe";
                process.StartInfo.UseShellExecute = false;
                process.StartInfo.CreateNoWindow = true;
                process.StartInfo.Arguments = "D:\\Projects\\Pub\\WebServices\\MoHuntEdWebSvc\\SCRIPTFILES\\CreateFTPStudentFile.vbs";
                process.StartInfo.Domain = "mydomain";
                process.StartInfo.UserName = "myuserid";
                _password = "mypassword";
                process.StartInfo.Password = new System.Security.SecureString();
                foreach (char c in _password)
                {
                    process.StartInfo.Password.AppendChar(c);
                }

                process.Start();

RESULTS:  a window comes up with error:  cscript.exe - application Error
 The application failed to initialize properly (0xc0000142). Click on OK to terminate the application


This is suppose to work with a web app and not just a windows app, right?

   
                Process process = new Process();
                process.StartInfo.FileName = @"Wscript.exe";
                process.StartInfo.UseShellExecute = true;
                process.StartInfo.CreateNoWindow = true;
                process.StartInfo.Arguments = "D:\\Projects\\Pub\\WebServices\\MoHuntEdWebSvc\\SCRIPTFILES\\CreateFTPStudentFile.vbs";
                process.Start();

creates no errors; however, it doesn't appear that my .vbs file ran.  I'm looking for my text file and it didn't get written.
