CURL HTTP Post For Visual Basic 2010?

Is it possible to use cURL and HTTP POST for visual basic?I am trying to make software version of my script to a client..I've created a system in PHP but I also want to let them use a software to post stuffs.

So the first thing I need is to login.

This is my form:

PHP
<form action="dologin.php" method="post">
Username: <input name="[b]myusername[/b]" type="text"><br>
Password: <input name="[b][COLOR="rgb(139, 0, 0)"]mypassword[/color][/b]" type="password"><br>
<input name="submit" type="submit">
</form>

How do I use VB to post my username and password to login?I tried download libcURL but i still do not get the gist from the example.Because usually u will need to define the field name of the post to execute the code. eg (myusername, mypassword)
