Hi,
I subclassed the cricheditctrl, I have text abcde. In onmousemove, if I put mouse pointer over c charfrompos returns 2;
If I move mouse pointer below c vertically(that is x coordinate is not changed y coordinate is changed) I am getting the same index 2 eventhough there is no character available where I am moving mouse pointer.

What happens if you move down, then left/right to position beneath another character. Does the value change?
See the doc :
Rich edit controls: The return value specifies the zero-based character index of the character nearest the specified point. The return value indicates the last character in the edit control if the specified point is beyond the last character in the control.
But by that definition, moving down (past the end of the single line of text) should have returned 4.
Yes, not very clear.
I did a test :

It appears that "under text" is treated as near rather than past the end.
