How do I make a flickering line ?

[gelatine1]

How should I make this line that's flickering in almost all text fields ? Should I keep track of the position and set some kind of timer that draws and removes this line ? How would I set this timer ?

I'm going to translate this to "how do I get a flashing caret?" - I assume that's what you mean.

Start with CreateCaret and explore the related functions, specifically SetCaretPos and DestroyCaret.

yes, thank you. Just what I need :)
