Is there an alternative to Application.Run

[John Pritchard]

I'd like to call sub routines that reside in another workbook. I know about
application.run but if I want to pass arguments byref it doesn't seem to work
(i.e. the changed value is not passed back). In the Vb help on calling
procedures with the same name there's this example:-
Sub Main()
[MyProject.vbp].[MyModule].Main
End Sub

I've tried renaming projects and using this:-
Sub Main()
[MyProject.xls].[MyModule].Hello
End Sub

...but can't make it see my hello procedure.
Where am I going wrong and once right will it allow me to do things like
this:-

Sub Main()
a = 1
b = 2
[MyProject.xls].[MyModule].Swap(a,b)
msgbox ("Swapped " & a & "," & b)
End Sub

Any help much appreciated! J.P.

Try it like this:

Application.Run "Workbook1.xls!Module1.Procedure1", Arg1, Arg2

RBS

You would need to create a reference from the calling workbook to the
workbook with the procedure. Do this in the VBE under tools=>References.
Make sure you have given the called workbook a unique project name in
properties (rather than the default VBProject).

Note that whenever you open the referencing workbook, the referenced
workbook will be opened as well. You can not close the referenced workbook
until the referencing workbook is closed.

Once the reference is established, you can call routines in the referenced
workbook as if they were local. You wouldn't need to qualify with the
workbook name or module names unless their were duplicate names in scope.

Thanks for the reply BUT the problem is Arg1 and Arg2 are passed by value
i.e. I can't see the changes that the called routine made to them.

Try it like this:

Application.Run "Workbook1.xls!Module1.Procedure1", Arg1, Arg2

RBS

Thanks Tom - Just what I needed!!

OK, I am sure it can work.
Try to make it a function with return values.
You could make it return an array holding the 2 values.

In Book1:

Sub test()

Dim lVal As Long

lVal = 1

MsgBox Application.Run("Book2.xls!Module1.TestFunction", lVal)

End Sub


In Book2:

Function TestFunction(ByRef lVal As Long) As Long

lVal = lVal + 1

TestFunction = lVal

End Function


I find setting references to other workbooks can cause a lot of trouble and
I find it is best to avoid it if you can.
