how to use mailto protocol ?

I would like to know how to send a formatted email via html.
I am using the form method and specifying the mailto protocol in it.
All i want is to send all the contents of the form in a formatted form to the outlook express.

<a href=mailto:[email protected]?subject="hello"?body="Name is:uhmnc Designation =ceo">


************************************** currently the results i am getting is
name="uhmnc"designation="c.e.o"
The result is appearing on the same line
How to format the above text by using new line
which i want as
name="uhmnc"
designation="c.e.o"

The following example shows a link that will prepare an e-mail message with multiple lines of text in the body.

<A HREF="mailto:[email protected]?
subject=Feedback&
body=The%0d%0aInetSDK%0d%0aSite%0d%0aIs%0d%0aSuperlative">
Click here to send feedback to the InetSDK.</A>



Here is some VC++ code:
void CApp::OnMySendMail()
{
CString strAddress("[email protected]");
CString strSubject("Phone Book Entry");
CString strBody("Dave Paxton%0d%0a1-234-567-8901%0d%[email protected]");

CString strCommand="MailTo:" + strAddress + "?subject=" + strSubject + "&body=" + strBody;

ShellExecute( NULL, "open", strCommand, NULL, NULL, SW_SHOWNORMAL);
}
