Gets or sets a value that specifies whether the InkCollector object collects pen input.
Assembly: Microsoft.Ink (in Microsoft.Ink.dll)
In addition to ink, pen input may include in-air packets, cursor in range events, and so on.
The InkCollector object collects ink in Microsoft® Windows® XP Tablet PC Edition or any edition of Windows 2000, Windows Server 2003, or Windows XP on which the Windows XP Tablet PC Edition SDK is installed. However, handwriting recognition occurs only if you use Windows XP Tablet PC Edition. In any edition of Windows 2000, Windows Server 2003, or of Windows XP other than Windows XP Tablet PC Edition, the property is always false if the Windows XP Tablet PC Edition SDK is not installed.
If the window input rectangle of an enabled InkCollector or InkOverlay (set in the constructor or with the SetWindowInputRectangle method) overlaps the window input rectangle of an InkCollector, a COMException exception is thrown.
Overlap can occur without an error as long as only one of the input rectangles is enabled at anytime.
While a control is not enabled, you receive no events.
When you set the property of a container control to false, all of its contained controls are disabled as well.
You cannot set the property to false while the object is collecting ink (CollectingInk property is true.)
The property must be set to false before setting or calling specific properties and methods of the object. If you try to change the specified properties or call the specified methods, an error occurs.
The following properties and methods cannot be set or called unless the property is first set to false:
You should set the property for an InkCollector object to false before you shut down an application.
This function can be re-entered if the property is set within certain message handlers, causing unexpected results. Take care to avoid a reentrant call when handling any of the following messages: WM_ACTIVATE, WM_ACTIVATEAPP, WM_NCACTIVATE, WM_PAINT; WM_SYSCOMMAND if wParam is set to SC_HOTKEY or SC_TASKLIST; and WM_SYSKEYDOWN (when processing Alt-Tab or Alt-Esc key combinations). This is an issue with single-threaded apartment model applications.
