In some versions of Excel, sending a DisplayAlerts command from external of
Excel, only is applied for that command - I believe this was fixed in xl2000
SR1. The recommended solution is to run a macro internal to excel where the
display alerts is set and the command executed.

Can't say if this is your problem, but may be.

I am calling the Range::Replace(..) function in Excel by an automating
app. I would like to not have a dialog box come up if no matches are found
for my search object. I tried setting DisplayAlerts == false, but this
doesn't seem to have any effect. Any ideas??

thanks,
