Show format characters

I wanted an edit that shows format characters ('TAB' and 'CR\LF'). I tried a little with an CEdit but it never worked.

The I found CRTFCtrl::GetCharPos() which will give you the coordinates of a given character in the control. With this function I was able to determin the position of the format characters I wanted to be shown.

So all I do is everytime the content of the control alters I redraw every visible format character.

The approach is very generic and can be used for other effects.

BUGs: If you drag and drop text with format characters, the selection remains (-> any help with this problem is welcome!)

    This means that the control is handling the insert itself and your code doesn't know that the text has been inserted.
    Grab this message and put the text through your own stream handler.

    Don't forget to check the validity of the data, as you would with clipboard data.

    Your use of Streamin/out is much better than mine was, thanks for the info.
