Recently a project need to read the web pages for data docking, a web content is as follows:

& lt; Div id="div1" name="RE" & gt; Hello, this is the data! & lt;/div>


Ask, how to use VC through Microsoft web browser control, read data from a DIV column above?


Are the requirements for the final result:

Cstrings sStr;

SStr="hello, this is data!"

Please advise,
