Hi, am trying to display the progress of a process in percentage but sort of like when you use the command prompt to format a drive and it shows the percentage done. Problem is how to display the changing percentages on the same line. Console.Writeline(value) just wrote the %age on a new line. Anyone knows how to do this?

gee, thanks but am just curious if all other escape literals have 'codes'. I mean, did you cram '0x8' or you have a list somewhere? Either way sounds like a messy affair.

I don't understand you question, sorry. Backspace code is unusual, it is processed by UI like a "characters" unlike other non-character key presses. There are raw several levels: raw codes from keyboard from all keys (including those like Shift), up and down, then OEM codes, system scan codes and characters and keyboard states on top; and on top of stack it depends on the active keyboard layout.

Solution 1

Use Console.Write(), and at the beginning of each string put a backspace character for as many non-backspace characters as you wrote the previous time.

thanks,sounds like what I need but,um, what is the backspace character look like? I know '\n' is for a new line and '\t' for tab but backspace doesn't ring a bell.

Mwanzia_M 15-Apr-11 16:26pm

hold that thought, figured out it should be '\b'. Thanks for your help.
