Re: execute script - C# Discussion Boards

15-Jun-09 0:24

Hi,
Now, I have the c# code to execute a vbscript on a remote machine which then returns success or failure.
Now I just can not figure out how to return into c# the result of the script that gets executed.
I am using WMI at present.
Any thought please?

Hi,,

You can something like this

ManagementClass processClass = null;
processClass = new ManagementClass(manScope, managementPath, objectGetOptions);

ManagementBaseObject inParams = processClass.GetMethodParameters("Create");

ManagementBaseObject outParams = processClass.InvokeMethod("Create", inParams, null);

string returnValue = outParams["returnValue"] == null ? string.Empty : outParams["returnValue"].ToString();

Hope it helps..

Hi,
This is what I have now but I am not sure how to tell the code to use the vbscript i.e. Wscript.echo "hello"
Any thoughts please?
Thanks

System.Management.ManagementOperationObserver observer = new System.Management.ManagementOperationObserver();
System.Management.ConnectionOptions conn = new System.Management.ConnectionOptions();

conn.Impersonation = ImpersonationLevel.Impersonate;
conn.EnablePrivileges = true;
conn.Authentication = AuthenticationLevel.Default;
System.Management.ManagementScope ms = new System.Management.ManagementScope(@"\\" + txtTargetMachine.Text + @"\root\cimv2", conn);

ms.Connect();

System.Management.ManagementPath path = new System.Management.ManagementPath("Win32_Process");

ObjectGetOptions objectGetOptions = new ObjectGetOptions();

ManagementClass processClass = null;

processClass = new ManagementClass(ms, path, objectGetOptions);

ManagementBaseObject inParams = processClass.GetMethodParameters("Create");

ManagementBaseObject outParams = processClass.InvokeMethod("Create", inParams, null);

string returnValue = outParams["returnValue"] == null ? string.Empty : outParams["returnValue"].ToString();

0. Try encoding your code in PRE tags to make it more readable; use the code block button at the bottom of this page.

System.Management.ManagementOperationObserver observer = new System.Management.ManagementOperationObserver();
System.Management.ConnectionOptions conn = new System.Management.ConnectionOptions();
//ad nasium

1. Redirect the stdout stream - StandardOutput method of the Process class - and read that.

I am not sure what you mean.
Please give an example.
Thank you

For two days, it has been suggested you look at using the Process class.
If you run your script from within a process, you can redirect the stdout and read it within your program.
The other wapproach is in when you launch your process to redirect standard output to a file. Once your script has completed then read in the content of the file.

I will not google this for you, but there is a lot of information about redirecting output and launching processes from C#. Go read up on it, have a try and come back when you hit a wall. NB - that means yoiu have tried for more than five minutes.

how to clear string memory from heap without using GC

15-Jun-09 20:08

Hello,
I created a sample.vbs script which has this in it. i.e. Wscript.echo "Hello"

The strOutPut = "Microsoft (R) Windows Script Host Version 5.6\r\nCopyright (C) Microsoft Corporation 1996-2001. All rights reserved.\r\n\r\nHello\r\n"

After reading I have now tried to do the following:

string scriptPath = @"\\" + txtTargetMachine.Text + @"\c$\sample.vbs";
//string scriptPath = @"c:\sample2.vbs";

System.Diagnostics.Process proc = new System.Diagnostics.Process();
proc.StartInfo.FileName = "cscript.exe";
//proc.StartInfo.FileName = "Wscript.exe";
proc.StartInfo.Arguments = scriptPath;
proc.StartInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
proc.StartInfo.UseShellExecute = false;
proc.StartInfo.RedirectStandardOutput = true;
try
{
proc.Start();
}
catch (Exception scriptError)
{

}
proc.WaitForExit();
int exitCode = proc.ExitCode;
string strOutPut = proc.StandardOutput.ReadToEnd();
string strErr = proc.StandardError.ReadToEnd();
proc.Close();

And how would you expect this to work? Strings are managed resources, so are subject to being tidied up by the Garbage Collector. Without using an unmanaged string, I couldn't see an easy way to satisfy this requirement. What could you possibly be doing that you wouldn't want to rely on the GC here?

Why do you want to do this? Garbage collection takes care of itself, so its something you rarely want to get involved with.

Do you mean without waiting for garbage collection?

You can call GC.Collect()[^] to force a collection.

Read Rico's guide to When to call GC.Collect()[^] first though. Generally calling GC.Collect() is a bad idea, you are much better off just letting the GC handle itself.

Your question is not very clear.

Have you looked at the RichTextBox control? It's a reasonably well-featured control that's capable of some of the wizadry you'd normally expect from a word-processor.

My original thought was RichText, I was just trying to pre-empt the 'why isn't the output in HTML' question tomorrow afternoon.
