How to extract data from a webpage and enter into an Access Database?
I have a Microsoft Access 2010 Database with a table and a form to read data from a webpage.
When I enter a number into the form, the form must have code to open the corresponding webpage and read a range of data from fields in the web page into the table in the database.
I only want the pages as I enter the numbers (SAQA QUAL ID = fugures long). I don't want the whole website as the information may change any time.
Typical page addresses are
http://allqs.saqa.org.za/showQualification.php?id=62322
http://allqs.saqa.org.za/showQualification.php?id=59769
Note the 5 digit number at the end. So I think that will be simple to just add the number to the first part of the url. But what then?
I want the attach the VBA code to the provided button on the form.
Database is attached
Where and how should I start?
