Thanks! I didn't think of looking for alternatives to string.

Interesting. Not heard of that before, but I'm curious as to how you'd actually use it. For instance, say I wanted to store a password someone had entered into a textbox - that's already available in unencrypted form in the Text property.
Even copying the password character by character which seems to be the norm with this thing would mean presumably interning the Text property of the Textbox - we've already lost the battle.
I think I'm missing something here - although its good that we can store things in memory in encrypted form how do we populate it, access it, compare it etc?

That does seem to be a problem on close inspection - to use it, it seems you have to get a pointer to unmanaged memory and then copy it out. Not sure this is going to quite do what I want - I'll keep looking tho.

Yes, it's a tool. We are supposed to build are own solutions using it like Paul Glavs did[^]

I'm not that paranoid, but you could probably use unsafe code to wipe the string.

Let's assume this held your bank account number, login id and password, and your paypal details.
Feeling paranoid enough yet?

Hi friends,
I wanted to add string resource to all exe and dll used in my project.
All exe and dll used in my project is not .net assembly, few of them are c++ and 3rd party dll.
At runtime I want to add/edit few string to all dll’s and exe’s used in my project, like myVersionInof, myImpectType etc, Which I can use in my project at runtime.
Can you guide me what should I have to use? Resource manager to add string resource.
Or add custom attribute to all my exe’s and dll’s .
Thanks

This sounds a bit dodgy to be honest.
What do you actually need to do?
What is the reason for adding an attribute?

I agree with Nagy - it sounds dogdy, and will be difficult to do as that is exactly what antivirus software is there to prevent...

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

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();
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.

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();

hi,
i am using for loop and assigning value to a string.the reference of the memory get cleared after exiting the loop but the memory exits ,so I wanna clear heap memory without using Garbage collection within the loop.
Reply soon.
Thanks in advance.

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.
