Display and Hide Text in Text Field

Text fields are used to received input from the user or display some text on a specific text area. In this problem we have two buttons one is to show text and second for hiding the text. When user press show button the program shows some text on the text area and when press hide button then program hide that text.

  3. This is in vb:
    Just define a as public variable in general as follow:
    Public a As String
    --------------------------------------------------------------------------------------------------------------
    and in Show button type the following code:
    Text1.Text = Text1.Text & a
    ----------------------------------------------------------------------------------------------------------------
    And in the Hide button type the following code:
    a=Text1.Text
    Text1.Text=""
    -----------------------------------------------------------------------------------------------------------------
    Regards

    Ali Sattar :)
