Run command line from vb.net

[venky5186]

How do I run commands like cacls or any other windows commands using vb.net


I am unable to run commands using the shell method in Vb.net but I would like to be able to run other executables with command line switches from a vb.net application.

Please help.

If you're trying to start other processes with arguments then the ProcessStartInfo Class will probably be useful, with the .Arguments property also. Is that what you were looking for?

This is what I am trying to do,I am trying to integrate the cacls utility(Microsoft utility to remove ntfs permissions) onto a vb.net project.

I would like to run the following command using a form based application.

My form will have a textbox which will take an input of the files for which permissions need to be removed.

On a button click it should be able to run the cacls utility with the following parameters.

cacls.exe "filename" /d everyone.
the file name part will be replaced with the +textbox1.text+

any suggestions let me know.

You'll need to use the ProcessStartInfo object.
Also, use String.Format instead of string concatenation:

Dim psi As ProcessStartInfo
Dim procname As String = "calcs.exe"
Dim filename As String = "whatever.txt"
Dim args As String = String.Format("{0} /d everyone", filename)
psi = New ProcessStartInfo(procname, args)
Dim proc As New Process()
proc.StartInfo = psi
proc.Start()

Dim proc As New Process()
proc.StartInfo = psi
proc.Start()
 

I was able to run the utility,just one more information,after execution I would like to make the program pass another argument -Y

Basically it is cacls.exe "filename" /d everyone

on pressing enter- it shows

Are you sure?Y/N

How would I pass the Y onto the command.
Appreciate your help in this..

I think i understand you...did u try using

Shell("calcs myfile.txt ")

replace myfile.txt with the filename you want to run it on

Ahh, the calcs program also waits on user input?
In the ProcessStartInfo object there is a ".RedirectStandardInput" property. Set it to true.
Then you can do this after the .Start() call
myprocess.StandardInput.Write("Y");

Note: You may have to wait a few cycles before calling that.
So like:

myprocess.Start();
Thread.Sleep(100);
myprocess.StandardInput.Write("Y");//do you need to press the enter key? I think you would change it to myprocess.StandardInput.WriteLine("Y")
