Using Input Box and a Command Button to launch a DOS app

there is a Shell command in vb that will let you enter batch commands, but it doesn't wait for the command to finish before going on to the next vb command. So i like to use the WSH object Shell, like this:

Cmd1 = "dir > C:\test.txt"
Set objWsh = CreateObject("WScript.Shell")
Call objWsh.Run("cmd /c " & Cmd1, 0, True)
Set objWsh = Nothing

you need the cmd /c part so that you can run things built into dos (that is, that aren't .exe's)
the ,True part tells it to wait for the doc command to finish before continuing
The .Run command doesn't show up as a command prompt window, but also doesn't allow results to be returned, thus the pipe for my dir command.  Another way to get results is to use the .Exec command instead, but it shows up as a blak command prompt which i find distracting. Here should be a link to the help page for these:

By "input boxes" you mean TextBox Controls or Popup window that get user's input?

If its Textboxes You can use something like this:

Private Sub Command1_Click()
Dim Cmd As String
Cmd = "BESUserAdminClient -add -u " & Text1.Text & " -p " & Text2.Text
Shell Cmd
End Sub

Private Sub Command2_Click()
Dim Cmd As String
Cmd = "BESUserAdminClient -del -u " & Text1.Text
Shell Cmd
End Sub

Private Sub Command3_Click()
Dim Cmd As String
Cmd = "BESUserAdminClient -add -itpolicy" & Text3.Text
Shell Cmd
End Sub


Its good Idea to check user input prior to execute the command:
Like this :

Private Sub Command2_Click()

If Text1.Text="" Then
   MsgBox "Please enter valid Username"
   Exit Sub
End If

Dim Cmd As String
Cmd = "BESUserAdminClient -del -u " & Text1.Text
Shell Cmd
End Sub

Thanks Mike, I'll check this over the weekend on the machine I'm using...

That would be a PopUp window that gets a user input
