It is not "global"; You are just confusing the issue by saying that.

Thank you for clarifying my confusion, Jochen!! :D I appreciate it.

The 18 is the RTM number from my above link. What a mess with all these different numbers for a single product :mad:

Looks like a typo, to me.

You are right about the copyright stuff. However, with complete respect to you and your opinion, not all people can get what they want especially if the thing related with payment(s) because they may have no money or it will cost them lots of money for me for example to buy this book for me will cost 2080 EGP so if for example, has a need for 10 books I will pay like 20800 EGP and that is lots of money for me + shipping fees, sorry for talking to much but I am trying to explain why I was asking for help from someone who may have it. Also I could have a book I do not need it or use it and a friend want it and was about buying and I give him mine so do you think it is violation in such situation?!!!. Wishing you good day :)

Well, that is quite different from the code in your original question.

I figured it out, Richard. You have to do a FillRect(...) on the pristine CRect rcl = pInfo->m_rectDraw (in OnPrint()). That should happen before the printer thread is started. Thanks.

hi, I have the same problem. how to solve this ?

Thanks guys for the help.

Quite possibly yes, but it is impossible to be sure. You would need to collect some decent debug information in order to be certain why the crash occurs.

The way you can do it is to simply have a timer, capture when the timer is triggered - and if you wish, compare with former screen (bitmap). 3. I'm not sure what you're trying to achieve, since there may be other ways to find out "when screen is updated" depending on your actual needs - perhaps you might be only interested in a specific window(s)? It would be a smart choice to minimize the area you're capturing, since that can indeed take a while and it's not really a good idea to to it too fast (not to mention - what if the user has a few monitors, and/or high resolution ones) 4. If you're just trying to learn programming, I suggest you take an easier task. Best, John -- LogWizard Meet the Log Viewer that makes monitoring log files a joy!
