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()
