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 ProcessStartInf o 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(Microso ft 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 ProcessStartInf o 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.Start()

I was able to run the utility,just one more information,aft er 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 ProcessStartInf o object there is a ".RedirectStand ardInput" property. Set it to true.
Then you can do this after the .Start() call
myprocess.Stand ardInput.Write( "Y");

Note: You may have to wait a few cycles before calling that.
So like:
[code=c#]
myprocess.Start ();
Thread.Sleep(10 0);
myprocess.Stand ardInput.Write( "Y");//do you need to press the enter key? I think you would change it to myprocess.Stand ardInput.WriteL ine("Y")
