示例

此示例返回一份报告，其中列出 InkOverlay 对象 mInkObject 所引用的 Tablet 对象的属性。

Public Function InkObjectTabletReport() As String
    Dim Result As StringBuilder = New StringBuilder(512)
    ' Wrap access to the Tablet object in a try/catch block. 
    ' If mInkObject is in All Tablets mode, an exception will be 
    ' thrown when accessing the Tablet property.
    Try
        Result.AppendLine("The tablet associated mInkObject has the following properties:")
        ' accessing mInkObject.Tablet will throw an exception if in All Tablets mode
        ' mInkObject can be InkCollector, InkOverlay, or InkPicture
        Dim mTablet As Tablet = mInkObject.Tablet
        Result.AppendLine("Tablet Name: " + mTablet.Name)
        Result.AppendLine("Tablet PNP ID: " + mTablet.PlugAndPlayId)
        Result.AppendLine("Tablet Max Rect: " + mTablet.MaximumInputRectangle.ToString())
        Result.AppendLine("Tablet Capabilities: " + mTablet.HardwareCapabilities)

    Catch ex As System.Exception
        Result.AppendLine("mInkObject is in all tablets mode.")
        Result.AppendLine("The tablet report cannot be generated.")
    End Try

    Return Result.ToString()
End Function

    // If mInkObject is in All Tablets mode, an exception will be 
    // thrown when accessing the Tablet property.

        // mInkObject can be InkCollector, InkOverlay, or InkPicture
        Tablet mTablet = mInkObject.Tablet;
        Result.AppendLine("Tablet Name: " + mTablet.Name);
        Result.AppendLine("Tablet PNP ID: " + mTablet.PlugAndPlayId);
        Result.AppendLine("Tablet Max Rect: " + mTablet.MaximumInputRectangle.ToString());
        Result.AppendLine("Tablet Capabilities: " + mTablet.HardwareCapabilities);
    }
    catch (System.Exception)
