how to call command window with VB.NET programme hi,
i want to integrate VB.NET with command window.
in fact, i want the interface(built on VB.NET) to open the command window and it should automatically change the path to C:\Perl\eg and then it has to execute automatically the file what i specified. for this i already used the code given below .
Shell("cmd.exe /k cd C:\Perl\eg", vbNormalFocus)
when i add this code, its opening the command window and the path is changed to C:\Perl\eg. but i need to type the below command on command prompt after changing the path to execute the perl code.
ex: perl filename.pl
But i want the above command to be executed automatically not manually. For that i've to add that command somewhere in VB.NET. But i don't know where to add and how to add exactly.
i hope somebody helps with this as early as possible.
thank u.

hmm i don't know for sure, but look into the process command, maybe you could just pass strings to it.

Try this in your main form load event:
Without the With statement:
Read up on the Process function. Can do a lot more than Shell. Like redirect the output to a textbox so you don't have to remember what the dos screen said.
Private Sub frmMain_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim process As New Process
With process
With .StartInfo
.FileName = "perl.exe"
.Arguments = "filename.pl"
.WorkingDirectory = "C:\Perl\eg"
End With
.Start()
End With
End SubWithout the With statement:
Dim process As New Process process.StartInfo.FileName = "perl.exe" process.StartInfo.Arguments = "filename.pl" process.StartInfo.WorkingDirectory = "C:\Perl\eg" process.Start()

It is hard to understand how a cemetery can raise its burial rates and blame it on the cost of living.

Try this:
Dim process As New Process process.StartInfo.FileName = "perl.exe" process.StartInfo.Arguments = "filename.pl" process.StartInfo.WorkingDirectory = "C:\Perl\eg" process.StartInfo.UseShellExecute = False process.StartInfo.ErrorDialog = False process.StartInfo.RedirectStandardOutput = True process.Start() TextBox1.Text = process.StandardOutput.ReadToEnd process.WaitForExit()
