Log on batch file

Hey I am looking for a command to log into a citrix server. When I go to the citrix site it asks for the username and pword... I was able to write the batch file to get me to the page however I'm not sure what the proper syntax is so that it will put in the username and pword to log me into the server. After I get logged into it I also need to click on a folder to have access to my resources. Is there a way to do this???

Thanks in advance!
