I am trying to create a simple dialog in MFC using Visual C++. My problem is that when I get the dialog on the screen and try to type in an Edit Box field, if I type the letter ‘a’ once, it appears in the edit box as ‘aaaaaaaaaaa’ (that’s 12 a’s). Furthermore, if I try to navigate around in the box using the arrow keys, the carat moves 12 characters at a time.
It’s not just a display error, as the output from the editbox is still ‘aaaaaaaaaaaa’.
I’d post code, but there’s really none to post. I added the edit box using the Toolbox in Visual Studio and assigned a variable to it in my class so this isn’t any sort of special edit box.
If anyone has any thoughts as to what might be happening it would be greatly appreciated. Unfortunately, I don’t know where to begin.
Thank as always.
Are you capturing any events such as WM_KEYUP in your PreTranslateMessage() function or anywhere else in your app ?
If you have overridden the default handling for keyboard events, it might cause the symptoms you are seeing.
