IHTMLWindow3::attachEvent Method

Binds the specified function to an event, so that the function gets called whenever the event fires on the object.

Syntax

HRESULT attachEvent(
    BSTR sEvent, 
    IDispatch *pDisp
);

Parameters

sEvent

String (BSTR) variable that specifies the name of the event.

pDisp

Address of an IDispatch interface that specifies an object to be called whenever sEvent fires.

Return Value

Returns S_OK if the function was bound successfully, or an error code otherwise.

Remarks

When sEvent fires on the object, the object's sEvent handler is called first, before the specified function, pDisp. If multiple functions are attached to the same event on the same object, the pDisp(s) will be called in a random order, immediately after the object's event handler is called.
