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?

You can use the function below to download the page and save as, say, "saqa.html"
This file you can attach via "External Data". Select More, HTML Document.
The wizard opens and you will have listed all the tables inside the document.
It is most likely the SAQA4 you will need. Finish the wizard and you the table attached.
However, it is in spreadsheet style so you are on your own how to proceed from here.

To read another page, you can download that page and overwrite the file linked to.
Option Compare Database
Option Explicit

Private Declare Function URLDownloadToFile Lib "urlmon" Alias "URLDownloadToFileA" ( _
    ByVal pCaller As Long, _

    ByVal lpfnCB As Long) _
    As Long

    Dim lngRetVal As Long
      
    lngRetVal = URLDownloadToFile(0, strURL & vbNullChar, strLocalFilename & vbNullChar, 0, 0)
    
    DownloadFile = lngRetVal
