shell()

can you call any command at the dos prompt using shell() or is it only certain commands?

There are no restrictions with shell and a dos command window.
:)

Thank you.

One more question regarding shell().
How do you get the DOS prompt to stay open once opened by vba?
I know there is some property but i cant remember what it is

If you pass the /C after the CMD.exe it will close the window and /K will keep it open.

VB Code:

Option Explicit
 
Private Declare Function ShellExecute Lib "shell32.dll" Alias "ShellExecuteA" (ByVal hwnd As Long, ByVal lpOperation As String, _
ByVal lpFile As String, ByVal lpParameters As String, ByVal lpDirectory As String, ByVal nShowCmd As Long) As Long
 
Private Const SW_SHOWNORMAL As Long = 1
Private Const SW_SHOWMINIMIZED As Long = 2
Private Const SW_SHOWMAXIMIZED As Long = 3
 
Private Sub Command1_Click()
    ShellExecute Me.hwnd, "Open", "C:\Windows\System32\CMD.exe", " /K Dir C:\", App.Path, SW_SHOWNORMAL
End Sub
