Are you talking about an on-screen keyboard? For only within your application or "system-wide"?

[Jimlesh]

Yea a virtual keyboard to use within the program.

Chr(8) is the backspace.

Chr(8) is the backspace.

How would i go about using it if the output was a textbox?

[RobDog888]

Heres a complete example.

Public Class Form1

	Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
		TextBox1.Text = "Blah,..."
	End Sub

	Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
		TextBox1.Focus()
		TextBox1.SelectionStart = TextBox1.Text.Length
		SendKeys.Send("{BACKSPACE}")
	End Sub

End Class

Thanks it worked but i dont really understand all thsi focus stuff im quite new to vb.

Is there any easier way to do it? basically just removing the last character inputted?

Thanks

Yes, its all still simple. The focus is needed because sendkeys send the key to the current active windo for input. So to insure the textbox is focused for input se set focus to it.

You can do similar with the keypress/keydown events and manipulations but is more code.
