static property System::Windows::Forms::OSFeature ^ Feature { System::Windows::Forms::OSFeature ^ get(); };public static System.Windows.Forms.OSFeature Feature { get; }static member Feature : System.Windows.Forms.OSFeaturePublic Shared ReadOnly Property Feature As OSFeatureProperty Value
An instance of the OSFeature class.
Examples
The following example queries OSFeature for the LayeredWindows feature. The version is checked to see if it is null, to determine whether the feature is present. The result is displayed in a text box. This code assumes textBox1 has been created and placed on a form.
private:
void LayeredWindows()
{
// Gets the version of the layered windows feature.
Version^ myVersion = OSFeature::Feature->GetVersionPresent(
OSFeature::LayeredWindows );
// Prints whether the feature is available.
if ( myVersion != nullptr )
{
textBox1->Text = "Layered windows feature is installed.\n";
}
else
{
textBox1->Text = "Layered windows feature is not installed.\n";
}
}
private void LayeredWindows() {
// Gets the version of the layered windows feature.
Version myVersion =
OSFeature.Feature.GetVersionPresent(OSFeature.LayeredWindows);
// Prints whether the feature is available.
if (myVersion != null)
textBox1.Text = "Layered windows feature is installed.\n";
else
textBox1.Text = "Layered windows feature is not installed.\n";
}
Private Sub LayeredWindows()
' Gets the version of the layered windows feature.
Dim myVersion As Version = _
OSFeature.Feature.GetVersionPresent(OSFeature.LayeredWindows)
' Prints whether the feature is available.
If (myVersion IsNot Nothing) Then
textBox1.Text = "Layered windows feature is installed." & _
ControlChars.CrLf
Else
textBox1.Text = "Layered windows feature is not installed." & _
ControlChars.CrLf
End If
End Sub
Remarks
Use this static property to query for operating system features. You cannot create an instance of this class.
To determine the version of a feature, call the GetVersionPresent method. To determine if a feature or a specific version is present, call the IsPresent method and specify the feature to look for with the feature identifiers provided in this class.
