The index of the Strokes collection to be removed from the CustomStrokes collection.
Заметки
A CustomStrokes collection is a reference to ink data and is not the actual data itself. This method removes only the related collection from a snapshot of, or reference to, the ink data and does not remove the actual ink data. To delete the collection from the actual ink data, call the Ink.DeleteStrokes method.
A System.ArgumentOutOfRangeException is raised if the index does not match an existing member of the CustomStrokes collection. If for development purposes you are using Windows XP (not the Tablet Edition) with the Tablet PC SDK installed and the index does not match an existing member of the CustomStrokes collection, a System.Runtime.InteropServices is raised.
Примеры
In this example, the Strokes collection that exists at the specified index of a CustomStrokes collection is removed. If a Strokes collection does not exist at the specified index, an exception is raised.
Private Sub RemoveCustomStrokes(ByVal mIndex As Integer, ByVal mInk As Ink)
Try
' if the indexed position does not exist, an exception will be raised
mInk.CustomStrokes.RemoveAt(mIndex)
Catch E As System.Runtime.InteropServices.COMException
' For Windows XP (not Tablet Edition) with Tablet PC SDK installed for development purposes
' this exception is raised when the indexed collection does not exist
Catch E As ArgumentOutOfRangeException
' For Windows XP Tablet Edition and Vista
' this exception is raised when the indexed collection does not exist
End Try
End Sub
private void RemoveCustomStrokes(int mIndex, Ink mInk)
{
try
{
// if the indexed position does not exist, an exception will be raised
mInk.CustomStrokes.RemoveAt(mIndex);
}
catch (System.Runtime.InteropServices.COMException)
{
// For Windows XP (not Tablet Edition) with Tablet PC SDK installed for development purposes
// this exception is raised when the indexed collection does not exist
}
catch (ArgumentOutOfRangeException)
{
// For Windows XP Tablet Edition and Vista
// this exception is raised when the indexed collection does not exist
}
}
