I don't understand what you want. Does this do the trick?

Private Sub Form_Load()
    txtID.Text = "a s d f"
    txtSerial.Text = txtID.Text
End Sub

Private Sub cmdGet_Click()
    txtSerial.Text = UCase(txtID.Text)
    txtSerial.Text = Replace(txtSerial.Text, "A", "0")
    txtSerial.Text = Replace(txtSerial.Text, "B", "1")
    txtSerial.Text = Replace(txtSerial.Text, "H", "2")
    txtSerial.Text = Replace(txtSerial.Text, "E", "3")
    txtSerial.Text = Replace(txtSerial.Text, "M", "4")
    txtSerial.Text = Replace(txtSerial.Text, "N", "5")
    txtSerial.Text = Replace(txtSerial.Text, "T", "6")
    txtSerial.Text = Replace(txtSerial.Text, "I", "7")
    txtSerial.Text = Replace(txtSerial.Text, "P", "8")
    txtSerial.Text = Replace(txtSerial.Text, "R", "9")
    txtSerial.Text = Replace(txtSerial.Text, " ", "")
End Sub
