    private void ReadProjects()
    {

        SqlDataReader rdr;

        Thanks, I got the QueryString working. The only problem now is that I get redirected to the companyadmin page even if the company role is not 'Admin'. Do you know how I can fix that? Thanks!

          User views and QueryString

          HI, I am trying to redirect users to the appropriate page based on the company role stored in the database. I have written the following code, but it doesn't seem to work. If the role is anything other than 'Admin', companyuser.asp x should load. Also, I am trying to append the user ID and username to the URL. At the moment it is hardcoded. Does anyone know how to obtain this from the db? Thanks in advance for your help!

          Code:
          protected
          ...

            That got rid of the two errors - thanks! However, I now get a new error message.

            'No overload for 'btnLogin_Authe nticate' matches delegate 'System.EventHa ndler'. Any ideas?

            I appreciate it!

                  I have this code to write to a file. However, this only saves one entry.
                  How can I save multiple entries, each saved in separate lines ?
                  At this point the output in the .txt file is strange:

                                I've created a GUI for a hospital visitor system to allow visitors to find patients based on surname. I've also made a table in access with patient names, surnames, date of birth, gender, ward, rooms, etc. I'm trying to figure out a way to connect to the table, and to retrieve patient details into JTextFields based on a search of a patient's surname. Any help greatly appreciated. Thanks in advance.
