I am having a vb.net application where i access SSRS reports in a web browser control using query string. I build the url and call the Navigate() method of webbrowser control with the url. My query is, I cannot pass the vb.net application logged in credential through the url. Bydefault the ssrs authticates the url using the system loggged in credentials. I have also tried to pass the credentials in the HttpHeader and pass it to the navigate method, but some how it is not working. Please help me with this.
