How to use any dos command inside a VB .NET?

[Worrow]

I tried to call "del *.bak" inside my program with process.start. However, since 'del' is not a file so it is not possible to use process.start to call it. I know there are other ways to do the same thing but I just want to use dos command. Any idea how?

 

Thanks in advance.

Have your program create a batch file that contains all the DOS

commands you want to execute. Then use Process.Start() to

run the batch.

:D Forget about dos and batch file command buddy :cool: Here is vb.net code for you.

 

Dim fs() As String, i As Integer
fs = Directory.GetFiles(Directory.GetCurrentDirectory, "*.bat")

For i = 0 To UBound(fs)
    File.Delete(fs(i))
Next

if you want to use the Dos method of deleting files from a folder, here's a quick sample i knocked up for you ...

       Dim pr As Process
       Dim args As New ProcessStartInfo("cmd.exe")
       With args
           .RedirectStandardInput = True
           .RedirectStandardOutput = True
           .UseShellExecute = False
           .WindowStyle = ProcessWindowStyle.Normal
       End With
       pr = Process.Start(args)
       '/// now lets delete all files with a .txt extension from the folder C:\testing\
       '/// you would obviously use *.bak instead of *.txt here ...
       pr.StandardInput.WriteLine("del C:\testing\*.txt" & Convert.ToChar(13)) '/// chr(13) being Enter key.
       pr.CloseMainWindow()

hope it helps :)

Hi! Your technique is cool buddy, but in this situation is different. I think to put an elephant into a refrigerator, just open the door and put it in. So...

 

Process.Start("c:\windows\system32\cmd.exe /c del *.bat")

dragon4spy's method is the best one. Edited February 14, 2004 by Volte

[msdn]System.IO[/msdn] is the best method...
