Shape.Hide Method

Conceals a line or shape control from the user.

Namespace:  Microsoft.VisualBasic.PowerPacks
Assembly:  Microsoft.VisualBasic.PowerPacks.Vs (in Microsoft.VisualBasic.PowerPacks.Vs.dll)

Syntax

'宣言
Public Sub Hide

public void Hide()

public:
void Hide()

member Hide : unit -> unit 

public function Hide()

Remarks

Hiding the control is equivalent to setting the Visible property to false. After the Hide method is called, the Visible property returns a value of false until the Show method is called or until Visible is set to true.

Examples

The following example demonstrates how to use the Hide and Show methods to switch between two shapes at run time. This example requires that you have a RectangleShape control named RectangleShape1 and an OvalShape control named OvalShape1 on a form. For best results, make both controls the same size and position one on top of the other.

Private Sub Form1_Load() Handles MyBase.Load
    ' Hide the oval.
    OvalShape1.Hide()
End Sub

Private Sub Shapes_Click() Handles RectangleShape1.Click, 
                                   OvalShape1.Click

    If OvalShape1.Visible = True Then
        ' Hide the oval.
        OvalShape1.Hide()
        ' Show the rectangle.
        RectangleShape1.Show()
    Else
        ' Hide the rectangle.
        RectangleShape1.Hide()
        ' Show the oval.
        OvalShape1.Show()
    End If
End Sub

private void Form1_Load(System.Object sender, System.EventArgs e)
{
    // Hide the oval.
    ovalShape1.Hide();
}

private void Shapes_Click(System.Object sender, System.EventArgs e)
{
    if (ovalShape1.Visible == true)
    // Hide the oval.
    {
        ovalShape1.Hide();
        // Show the rectangle.
        rectangleShape1.Show();
    }
    else
    {
        // Hide the rectangle.
        rectangleShape1.Hide();
        // Show the oval.
        ovalShape1.Show();
    }
}
