Compile and run it.

Maximize the window and the view;

Click the tab from "Report View 1" to "Report View 200".

Like this:

(My computer: Intel Core 2 Quad CPU Q6600 @2.4GHz; 2.00GB Memory; 1440*960 LCD.)

 

when clicked about  "Report View 114", the window painted ugly.(I'm sorry to say that i can't capture the window!)

 

and on a computer of Intel Pentium IV 3.0GHz; 1.00GB Memory; 1280*1024 LCD, it appears at "Report View 22" or more.

 

but if i replace  CXTPReportView with CEditView, it works well.

 

why?
