Namespace: Microsoft.Ink
Assembly: Microsoft.Ink (in Microsoft.Ink.dll)
Syntax
'Declaration
Public ReadOnly Property ExtendedProperties As ExtendedProperties
'Usage
Dim instance As Ink
Dim value As ExtendedProperties
value = instance.ExtendedProperties
public ExtendedProperties ExtendedProperties { get; }
public:
property ExtendedProperties^ ExtendedProperties {
ExtendedProperties^ get ();
}
public function get ExtendedProperties () : ExtendedProperties
Property Value
Type: Microsoft.Ink.ExtendedProperties
The collection of application-defined data.
Remarks
Applications can use the ExtendedProperties property to access the custom data that is stored in the Ink object. This custom data is automatically serialized with the object.
Examples
In this example, the Dirty property is examined. If true, the Ink object of an InkOverlay object is saved to a file in the default InkSerializedFormat (ISF). An ExtendedProperty is added to the Ink object to track the time that the ink was saved.
Try
If mInkOverlay.Ink.Dirty Then
' TIME_GUID is a class level string set via GUID generator
Dim timeGuid As Guid = New Guid(TIME_GUID)
mInkOverlay.Ink.ExtendedProperties.Add(timeGuid, DateTime.Now)
' FILE_NAME is a class level const
Using FS As FileStream = New FileStream(FILE_NAME, FileMode.Create)
Dim isf As Byte() = mInkOverlay.Ink.Save()
FS.Write(isf, 0, isf.Length)
End Using
End If
Catch
' handle or rethrow
End Try
try
{
if (mInkOverlay.Ink.Dirty)
{
// TIME_GUID is a class level string set via GUID generator
Guid timeGuid = new Guid(TIME_GUID);
mInkOverlay.Ink.ExtendedProperties.Add(timeGuid, DateTime.Now);
// FILE_NAME is a class level const
using (FileStream FS = new FileStream(FILE_NAME, FileMode.Create))
{
byte[] isf = mInkOverlay.Ink.Save();
FS.Write(isf, 0, isf.Length);
}
}
}
catch
{
// handle or rethrow
}
