edit control - entering only numbers

Hi, I'm wrtiting MFC application which is going to perform some calculations. I want to allow user to enter only numbers in edit control field. I'm using Visual C++ .net and set property "number" of edit control to true. That is working fine. But when user try to enter a letter he gets (I think windows) notification :
"Unacceptable Character
You can only type a number here"
Because English is not my native language and I don't want the application to be in English language I need to somehow turn it off. How can I do that?
I have win Xp service pack 2.
Thanks for help!

That functionality is most likely coming from a DDV_xxx() routine in your DoDataExchange() method. Comment out the DDV_xxx() routine for that edit control and see if the message box goes away.

Thanks, but that didn't help me much.
However, I figure out what cause it.When creating new project - MFC appliaction I left option Common Control Manifest checked in Advanced fetures. I simply deleted manifest file and manifest resources and it works now!
