Code tags - please - you might not get any replies otherwise.

Also - perhaps this would be better on the windows page - there is a button so you can move there.

In the header file you have a GetLineCount but no GetLine as the compiler says. And you don't show any implementation for either of them ( not that I could see)

HTH

kindly TheIdeasMan can you explain better ......
