Examples
The following code example demonstrates how to use the GetHbitmap method.
[System::Runtime::InteropServices::DllImportAttribute("gdi32.dll")]
static bool DeleteObject( IntPtr hObject );
private:
void DemonstrateGetHbitmap()
{
Bitmap^ bm = gcnew Bitmap( "Picture.jpg" );
IntPtr hBitmap = bm->GetHbitmap();
// Do something with hBitmap.
DeleteObject( hBitmap );
}
[System.Runtime.InteropServices.DllImport("gdi32.dll")]
public static extern bool DeleteObject(IntPtr hObject);
private void DemonstrateGetHbitmap()
{
Bitmap bm = new Bitmap("Picture.jpg");
IntPtr hBitmap = bm.GetHbitmap();
// Do something with hBitmap.
DeleteObject(hBitmap);
}
<System.Runtime.InteropServices.DllImportAttribute("gdi32.dll")> _
Private Shared Function DeleteObject (ByVal hObject As IntPtr) As Boolean
End Function
Private Sub DemonstrateGetHbitmap()
Dim bm As New Bitmap("Picture.jpg")
Dim hBitmap As IntPtr
hBitmap = bm.GetHbitmap()
' Do something with hBitmap.
DeleteObject(hBitmap)
End Sub
Remarks
You are responsible for calling the GDI DeleteObject
method to free the memory used by the GDI bitmap object. For more information about GDI bitmaps, see Bitmaps in the Windows GDI documentation.
