I am using an ado data control on a form in visual basic 6 to display and 
edit customer details held on a Sql server database. Each field is linked 
in the normal way via the data control using the datafield and datasource 
properties of the text box on the form. When I change the value in a 
particular field and the adodc willchangerecord event is called I get the 
following message

vb6.exe has generated errors and will be closed by windows.

Examining the error log I can see that the function call

msado15!dllGetClassObject is generating the fault.

Anybody come across problems with the ado control like this before? There 
doesn't seem to be anything on the microsoft support website. I have also 
installed visual studio 6 service pack 5 in an attempt to rectify this but 
still no luck.
