Using Wininet API with vb to perform a "POST" operation

I am trying to upload a file to a web server .Web server has a perl code for uploading the files.I am using "POST" method to send the path of file and other information to the perl code at web server.I tried using Internet transfer controls in vb to perform this function but did not succeed.Now i am trying to use Wininet API to perform this function. The material and examples that i found were using Wininet with C++ and not VB.<br>
As i am facing some problem using it with vb,can someone tell me from where can i get information for using wininet in vb<br>
Thanks<br>
