Howto use ConvertDatabaseDriver From VB 6

[ZakIOM]

HI
Old Reports in Ver 5
New Reports to be in 8.5

I have 500 + reports pointing to different SomeData.dat files using an old driver pdSomeOld.dll

I want a VB app to loop thru the reports and change the driver then save it with the new driver.
I have tried
oReport.Database.ConvertDatabaseDriver("p2someNew.dll", False)
AND the
oReport.Database.ConvertDatabaseDriver("p2someNew.dll", True)
BUT the driver is not changed.. IF i open thet report in CR ver8.5 The change is noted but the Change on Next Refresh is not Checked...

Is there anyway to automate this...
