Pass it like :

Shell "c:\myexe.exe MyVars"

and fetch it like

MyVar = Command()

If you're speaking of standard exes, you can pass parameters while shelling:
shell "c:\myexe.exe parm1,parm2,parm3"
and retrieve them in the shelled pgm using Command$ function:
dim retvar as string
dim parms() as string
But pass parameters back from shelled one to caller is not that easy. A workaround is to make the called write on a file, and the caller readingf the file from time to time (or - using waitforsingleobject Api - make the caller read the file only once the called pgm has ended its job).

Compile this as an exe and run the file with parameters

Private Sub Form_Load()
Dim CommandVars As String
CommandVars = Command()
If CommandVars <> "" Then MsgBox "You typed '" & CommandVars & "' as parameter", vbInformation
End Sub

Happy Programming,

Cos i am kind of new in this area i have to ask a silly question!!

Now in:  MyVar = Command()

So as what should i declare this variable as???
Does it has to be global???
And if i call it in Form_Load, I just go

Private Sub Form_Load()
MyVar = Command()

End Sub
