Gets or sets a value indicating whether a line or shape control is available to accessibility applications.

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

Syntax

'Declaration
<BrowsableAttribute(False)> _
Public Property IsAccessible As Boolean
'Usage
Dim instance As Shape 
Dim value As Boolean 

value = instance.IsAccessible

instance.IsAccessible = value

[BrowsableAttribute(false)]
public bool IsAccessible { get; set; }

[BrowsableAttribute(false)]
public:
property bool IsAccessible {
    bool get ();
    void set (bool value);
}

public function get IsAccessible () : boolean 
public function set IsAccessible (value : boolean)

Property Value

Type: System.Boolean
true if the control is available to accessibility applications; otherwise, false. The default value is true.

Remarks

When a line or shape controls is used strictly for decorative purposes and its Enabled property is set to false, you may want to set the IsAccessible property to false to minimize the effect on accessibility applications.

Examples

The following example sets the IsAccessible property of each shape in a collection to false if the Enabled property of that shape is false.

Private Sub SetAccessibility()
    ' Loop through the Shapes collection of the form. 
    For Each s As Shape In ShapeContainer1.Shapes
        ' If the shape is disabled, set IsAccessible to false. 
        If s.Enabled = False Then
            s.IsAccessible = False 
        End If 
    Next 
End Sub

private void SetAccessibility()
{
    // Loop through the Shapes collection of the form. 
    foreach (Shape s in shapeContainer1.Shapes)
    {
        // If the shape is disabled, set IsAccessible to false. 
        if (s.Enabled == false)
        {
            s.IsAccessible = false;
        }
    }
}
