how to backspace?

[whisperXming]

Hi, im doing a currency convertor program. I've done up most of the parts, but im not sure how to backspace. For example of user entered wrong number, when the user click on backspace, it'll delete the last number he entered.

thanks

Isn't that what backspace is suppose to do, delete the last entered character? What do you want the backspace to do?

sorry to cause the misunderstanding. what i meant was if user click on backspace, how should i put the code to let the backspace button delete the last number the user entered.

What have you got so far? Like, what is your program doing. I suppose you're using a text box. Are you converting the user's input from one currency to another currency in another text box? Or are you using the same text box to convert the text.

I still don't quite understand why the backspace isn't working. If you're converting the input into another different text box and leaving the input alone, and that text box, which contains the input, has focus, it should definitely delete the last entered character, unless you are coding with a textbox_textchanged event. Also, what language are you coding in?

So you're looking for the .NET equivalent of SendKeys(backspace)?

Hi

Why don't you create a validation that will prevent the user to enter wrong number?
