Som Thomas skriver men lite mer detaljerat.Sv:Starta andra program?
Det enkla sättet som du kan öppna .exe .bat .com
<code>
Option Explicit
Private Sub Command1_Click()
Dim oki As Long
' I samma mapp som ditt projekt .exe ligger i, ligger också "LäsMig.txt"
' oki = Shell("C:\Windows\notepad.exe" & App.Path & "\LäsMig.txt", vbNormalFocus)
oki = Shell("C:\Windows\notepad.exe", vbNormalFocus)
End Sub
</code>
Eller mer proffsigt
<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
Const SW_SHOWNORMAL = 1
Private Sub Form_Load()
ShellExecute Me.hwnd, vbNullChar, "ReadMe.doc", vbNullChar, App.Path, SW_SHOWNORMAL
Unload Me
End Sub
