I am trying to build an application that would connect to an Access database (DAO 3.60), containing URLs, fetch the links one by one and then write the status back to the database. First I used Inet control for that purpose, but it turned out to be too buggy, that's why have decided to wininet.dll istead (found some examples on the web and customized them). But the problem is that if a link is timed out the application hangs up, because I cannot set the time out for wininet.
Can anyone help me out?
So the form has:
1. Textbox named "txturl" - URL from the database are read into it
2. Richeditbox named "txtbuf" - HTML is read into it to find out the status of the website (Server not fount, page not found, etc.)
3. Commandbutton to start the procedure
