Hello,

From your post, my understanding on this issue is: you wonder whether it is
possible to run VBA function via OLE automation . If I'm off base, please
feel free to let me know.

The method 'Run' can only accept macro name and arguments as its
parameters. If we call the VBA functions, it will throw an exception: "The
macro '*****' cannot be found."

If your "VBA function" refers to the VBA built-in functions like "MsgBox",
there does not exist a direct method to call them. A possible workaround is
to dynamically create a macro that wrap the VBA function (see:
http://support.microsoft.com/kb/303871/), then call the macro with the Run
method.

If your "VBA function" refers to the Excel object model, we could call the
object model directly on the xlApp object. For example (in VB):
Dim oExcel As Object
'Start Excel and open the workbook.
oExcel = CreateObject("Excel.Application")
oExcel.Visible = True
oExcel.Workbooks.Add() ' call the excel object model

Please let me know if you have any other concerns, or need anything else.

Sincerely,
Jialiang Ge , remove 'online.')
