Can't you just check to see if the ascii value of the char entered is 8 (Backspace) and then tell it not to print out a *. I'm not sure what exactly you are doing so that is all i can help.

TopSpin is correct. Although Im familiar with passwords in C, you may have to test for the backsapce. Although, there may be another way.

You may just check the ascii value of the character and if its 8 then instead of adding an *, delete one. But thats just me and I really bet there is a better way to do it.

Now that I think about it, you may want to set it up that if they hit backspace, then just make them redo it. Helps with security I guess although it can be a hassle. Just a thought.
