I finally got it to work...

There it is :

#DEFINE xlDialogPivotTableWizard 312
#DEFINE xlExternal  2

DIME gaSelect[1]
gaSelect[1] = ""
lcODBCConnexion = "ODBC;DRIVER=SQL Server;SERVER= YourSQLServerName;UID=YourLogin;PWD=YourPassword;APP=Microsoft Visual FoxPro;DATABASE=DBName"

oXL = CREATEOBJECT("Excel.Application")
oWB = oXL.Workbooks.add()
oSheet = oWB.ActiveSheet
oXL.visible = .T.
oDialog = oxl.Dialogs(xlDialogPivotTableWizard)

oDialog.Show(xlExternal, @gaSelect,,,,,,,,,,,,, .T., lcODBCConnexion)

for External DataSource, the 1st, 2nd, and last parameters are mandatory.

Have a nice day,

Yanick
