How does the above code execute an infinitive loop? Actually, I never use Report DE too... Basically, if the report is called by the form and the data for the report would not change during life of this form, we can add a new property to the form nTotalPages, initialize it to 0. Then in the procedure, which calls the report, check for this form property, so we would not need to call this report to dummy file (I use this technique always instead of screen, since it provides more accurate result) more, than it's needed...
If it's not broken, fix it until it is.
