EPM API

Hi Expert,

I can't seem to get some API work and wondering if I'm doing anything wrong.

GetActiveConnection and GetColumnAxisMembers both return strings, and I could show the string result of the first API in the message box while failed on the second.  Any idea?  The vba codes are:

Dim api as New EPMAddInAutomation

str = api.GetActiveConnection(Worksheets("Report"))

MsgBox str

==> This will correctly return the Connection Name in the message box

str = api.GetColumnAxisMembers(Worksheets("Report"), "000")

MsgBox str

==> this will prompt an error: Compile Error, Type mismatch.

Thanks in advance,

Ben
