I'm working on an application that stays in background(Tray). From that application how can I write to currently focused textbox (of other application). I also want to delete a specific number of character from current cursor position in that textbox.

Any help is appreciated.

Is this some sort of random thing or do the applications "know about" each other? Are you writing both of them. Is it a particluar event that will trigger this behaviour? If you update your question with some extra detail along these lines it will help

If both of these are your applications then you can use any of the forms of Inter Process Communication[^] to communicate between them.

If the foreground app isn't yours or you can't change the code then you will need to get the handle to the edit control using PInvoke and do your thing from there - harder work but doable, plenty of examples online if you search.
