Hi everyone!


How can i run a exe from a dll and pass a variable to the exe?


Thanks.

In your dll you can have something like this:

Public Sub RunExe(prog As String, arglist As String)

    Shell prog & " " & arglist, vbNormalFocus

End Sub

where
- PROG must have full exe path+name
- and arglist is some list of command line arguments

In the program that will run on main ,form_load OR sub main you'll have to parse command line args like this:

Private Sub Form_Load()
Dim myComArgs As String

    myComArgs = Command()
    
    'you take from here...

End Sub

Good answer, but I'd tend to generalize it to:

Public Sub RunExe(prog As String, arglist As String)

    Shell """" & prog & """ " & arglist, vbNormalFocus

End Sub

Paths often have spaces, etc. in them.

Thanks but then you have to add Error Handler, "turn" sub into a function ... and so on ...
But I agree, dbl quotes most likely needed.
