示例
' ========================================================================================
' The following example creates a Font object, checks to see that the call to create the
' object was successful, and, if it was, uses the Font object to draw text.
' ========================================================================================
SUB Example_GetLastStatus (BYVAL hdc AS HDC)
' // Create a graphics object from the window device context
DIM graphics AS CGpGraphics = hdc
' // Get the DPI scaling ratio
DIM rxRatio AS SINGLE = graphics.GetDpiX / 96
DIM ryRatio AS SINGLE = graphics.GetDpiY / 96
' // Set the scale transform
graphics.ScaleTransform(rxRatio, ryRatio)
' // Create a Font object.
DIM font AS CGpFont = CGpFont("Arial", AfxPointsToPixelsX(16) / rxRatio)
' // Check the status of the last call.
DIM status AS GpStatus = font.GetLastStatus
' // If the call to create myFont succeeded, use myFont to write text.
