  HI

  I am making a Currency user control.

  What I needed to do is when I press "-" ( minus ) from keyboard in the textbox, the minus should appear at the front of  the integer  no matter when I press it. For example, I have typed a number in the textbox like 1,342,23   Now when i press " - " , it should appear at the front, like   -1,342,23.

  How can I do this ?

  Hello,

  You can try the given code. But you may have to manipulate according to your requirement. Private Sub TextBox1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles TextBox1.KeyPress

  If Not IsNumeric(e.KeyChar) Then

  e.Handled = True

  If Asc(e.KeyChar) = 45 And InStr(TextBox1.Text, e.KeyChar) = 0 Then

  Dim str As String

  str = String.Concat(e.KeyChar.ToString(), TextBox1.Text)

  TextBox1.Text = str

  TextBox1.Select(TextBox1.Text.Length, 0)

  End If

  End If

  End Sub

  I hope this helps.

  
  Regards,
