Find the cursor position in a textbox

[Neil Robbins]

Could anyone suggest a way in which I could find the position of the cursor
within a textbox.

I want to evaluate every keypress made within the textbox in order to
validate it but in order to do this I need to know where the cursor is when
the key is pressed. So far I can't see how I could do this.

Any help would be very much appreciated,

Hi Ken,

Thanks for the response, unfortunately I think that perhaps I should have
been a little more specific.

I need to to know the location of the text cursor, not the mouse cursor. So
if there are 10 characters allowed in the textbox and the user has entered a
string of 6 characters but has gone back to edit the third character I need
to know that it is the third character that is being edited and not the
second (or any other) character.

I hope that this clarifies things a little.

Any further help would be greatly appreciated.

I need to to know the location of the text cursor, not the mouse cursor. So
The text cursor is called caret.

Maybe you are looking for the control's 'SelectionStart ' property?
