示例

 

' ========================================================================================

' The following example creates a FontFamily object and then checks the status of the call

' to create the object. If the call was successful, the example draws 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 FontFamily object

  DIM myFontFamily AS CGpFontFamily = "arial"

 

  ' // Check the status of the last call.

  DIM status AS GpStatus = myFontFamily.GetLastStatus

 

  ' // If the last call succeeded, draw text.

  IF status = Ok THEN

     DIM solidBrush AS CGpSolidBrush = GDIP_ARGB(255, 0, 0, 0)

     DIM font AS CGpFont = CGpFont(@myFontFamily, AfxPointsToPixelsX(16) / rxRatio)

     graphics.DrawString("status = ok", -1, @font, 0, 0, @solidbrush)

  END IF
