How to enter spaces in RichEditControl ?

[VictorN]

Please go through this : http://www.termsys.demon.co.uk/vtansi.htm.

But what does it have to do with the Windows programming? Window is NOT just a terminal (or its part)

I'm trying to implement "Cursor Control" in RichEditControl.

Again: there is no any row/column in Richedit control. There is a client area and formatted rectangle instead.
Yeah, if control contained some text then we could talk about the lines with text. We could also talk about a character position on the line (so called "column" number) but only makes sense on the current line! If we look at some other (existent) line then the "column" number for the position with the same x-coordinate may and may not be the same; it also may be not defined if the line contains no text or the text is shorter (in pixels, not in characters!)

How can't you understand it?
