I have a detail page link that triggers an email when clicked and is located on a custom object..
On this same object, I have a visual force page button setup that extracts all the required information that would be needed in order to send an attachment.
I would like to be able to have this VF Page added as a PDF attachment when the Detail Page Link(email) is clicked.

The below is the URL Code I am using in order to send email;
https://mail.google.com/mail?view=cm&tf=0&to={!ThinkLP__Investigation__c.StoreEmail__c}
&cc=emailtosalesforce@9-34c5cusem7ueuofas0g02tx3yrdj4y4jw1vx8exj0s9xbjtxky.d-hqybeai.dl.le.salesforce.com;
{!ThinkLP__Investigation__c.DLPM_Email__c}
&tf=1&su="SAD: True Variance Alert" [Ref: {!ThinkLP__Investigation__c.Id}]
&body=

Any thoughts or suggestions?
