What does HWND do?

Rory · Apr 26th, 2005, 2:35 AM

In what context? HWND is a C data type that marshalls to a Long under visual basic, representing a unique numerical identifier of a window or window object under windows. These are used under VB6 primarily when calling APIs to interact with windows, and can be discovered using API methods or the Hwnd property of form and other objects. For example, the first argument of the SendMessage API function is hwnd, used to determine which window you are referring to.
