Ok, I have a Memo with a bunch of lines, but how do I know the first visible line
this is very simple
1 2 FirstLine := Memo1.Perform(EM_GETFIRSTVISIBLELINE, 0, 0);
The return value is the zero-based index of the uppermost visible line in a multiline edit control. For single-line edit controls, the return value is the zero-based index of the first visible character.
