IHTMLEventObj::qualifier Property

Gets the name of the data member provided by a data source object.

Syntax


HRESULT IHTMLEventObj::get_qualifier(BSTR *p);

Parameters

p
Pointer to a variable of type BSTR that receives the default data member either by the name of the data member or an empty string.

Return Value

Returns S_OK if successful, or an error value otherwise.

Remarks

Check the IHTMLEventObj::qualifier property in the event handlers of a data source object (DSO) if:

  1. The DSO supports multiple, named data members.
  2. You have specified a qualifier in association with the DATASRC attribute of an element bound to that DSO.

Valid qualifiers are specific to the DSO implementation. Check the documentation of the DSO to determine if it supports named data members and to determine the valid names for those data members.

Parameter p is passed with the event. In Microsoft Internet Explorer 4.0, it is always set to "".
