How can i make my 3 input boxes (for VB 6.0) make the user not insert letters, but numbers?

Question

ok there's an input box right, and when you open the input box you can enter letters or numbers or special characters,(REMEMBER THIS IS NOT A TEXT BOX, ITS AN INPUT BOX.) I just want the user to insert numbers and decimals, but no letters or special characters. * Visual Basic 6.0 Professional***can you please include an example,thx!****

Answer 1

In the keypress event of the input box write the following code

If (KeyAscii < 48) Or (KeyAscii > 57) Then KeyAscii = 0

Answer 2

The inputbox doesn't support what you are suggesting.

I suggest writing a custom input box using your own form so you can add a mask to the textbox.

Or simply validating the users input using IsNumeric() function.
