I've never done this, but one idea is to redraw the word/line with a paint brush that alternates colors depending on the character.
Example, if you wanted "Hello World" and wanted the "W" to be red after 1 minute you might have to paint the line 3 times. Paint: "Hello " (default color) Paint: "W" (in red) Paint: "orld" (default color) -d- On Fri, Aug 21, 2009 at 9:01 AM, manoj <[email protected]> wrote: > > Hi friends, > > How can I know the length of the each character of word. > > Actually, I am trying some thing like this: > > I will show some set of lines on the screen.
