How to use HttpOpenRequest() for "POST" method

[youngever]

Urgent,
I write a application for get CGI web page( which used POST method ),
but it did not work because The cgi didn't read my paraments.
How can I use the HttpOpenRequest() function for "POST" method!!!

HttpOpenRequest::
lpszVerb
Address of a string that contains the verb to use in the request. If this parameter is NULL, the function uses "GET" as the verb.
Mabe you can try this
OpenRequest
