InkEdit Control Reference

The InkEdit control enables you to collect ink, recognize ink, and display ink as text. This control allows you to enable smart forms, which improves the accuracy of text input.

This control is a superset of the RichEdit control. It extends the RichEdit control with the ability to capture, recognize, and display ink.

This object can be instantiated by calling the CoCreateInstance method in C++.

Creating the InkEdit control behind a transparent control (such as a GroupBox with the WS_EX_TRANSPARENT property set) will prevent InkEdit from collecting ink.
