  • Article

This content is no longer actively maintained. It is provided as is, for anyone who may still be using these technologies, with no warranties or claims of accuracy with regard to the most recent product version or service release.

Indicates that a conversation window has been closed. Scriptable.

Syntax

HRESULT OnIMWindowDestroyed(
   [in] IDispatch* pIMWindow
);

Parameters

Return Value

The implementer of this event handler will determine what value should be returned.

Remarks

It is not permissible to read properties such as HWND from pIMWindow with this event. By the time the local client communicator API application receives the event, the IM window in question has been destroyed. Attempting to read the HWND property of a window that does not exist raises an exception.

Example

The example code illustrates how to handle an IM window destroyed event. The pIMWindow object is not referenced in this code except as a COM object to be released by Marshal.ReleaseComObject().

void communicator_OnIMWindowDestroyed(
     object pIMWindow)
{
    try
    {
        if (object.ReferenceEquals(pIMWindow, newIMWindow))
        {
            StringBuilder sb = new StringBuilder();
            sb.Append(
               " IM WINDOW DESTROYED:");
            Console.WriteLine(
                    "EVENT: " +
                    sb.ToString());
            imWindow = null;
            if (MessWindIntForm != null)
            {
                MessWindIntForm.IMWindow = null;
            }
        }
        Marshal.ReleaseComObject(pIMWindow);
    }
    catch (NullReferenceException)
    {
        Console.WriteLine(
            "EVENT: " +
            "Null Reference exception IMWindow Destroyed");
    }
}
