Examples

The following method shows the use of the DpiX and DpiY properties. This example is designed for use with a Windows Form. To run this example, paste it into a form that contains a ListBox named listBox1 and call this method from the form's constructor.

private:
   void PopulateListBoxWithGraphicsResolution()
   {
      Graphics^ boxGraphics = listBox1->CreateGraphics();

      // Graphics* formGraphics = this->CreateGraphics();
      listBox1->Items->Add( String::Format( "ListBox horizontal resolution: {0}", boxGraphics->DpiX ) );
      listBox1->Items->Add( String::Format( "ListBox vertical resolution: {0}", boxGraphics->DpiY ) );
      delete boxGraphics;
   }

private void PopulateListBoxWithGraphicsResolution()
{
    Graphics boxGraphics = listBox1.CreateGraphics();
    Graphics formGraphics = this.CreateGraphics();

    listBox1.Items.Add("ListBox horizontal resolution: " 
        + boxGraphics.DpiX);
    listBox1.Items.Add("ListBox vertical resolution: " 
        + boxGraphics.DpiY);

    boxGraphics.Dispose();
}

Private Sub PopulateListBoxWithGraphicsResolution()
    Dim boxGraphics As Graphics = listBox1.CreateGraphics()
    Dim formGraphics As Graphics = Me.CreateGraphics()

    listBox1.Items.Add("ListBox horizontal resolution: " _
        & boxGraphics.DpiX)
    listBox1.Items.Add("ListBox vertical resolution: " _
        & boxGraphics.DpiY)

    boxGraphics.Dispose()
End Sub
