onreadystatechange Property (ServerXMLHTTP/IServerXMLHTTPRequest)

Specifies the event handler to be invoked when the readyState property changes. Note that onreadystatechange is designed for use in scripting environments and is not readily accessible in Microsoft® Visual Basic® or C++.

oServerXMLHTTPRequest.onreadystatechange = funcMyHandler;

HRESULT put_onreadystatechange(VARIANT* readystatechangeSink);



Name of the function that should be called when the readyState property value changes.

C/C++ Return Values


Value returned if successful.

The property is write-only. When using scripting languages, this property can be set in ways other than directly accessing the property through IServerXMLHTTPRequest. It can also be set using the onreadystatechange attribute of the <XML> tag, and the SCRIPT FOR... construct.
