Unhandled exception at 0x77124c47 in VB6.EXE: 0xC0000005: Access violation reading location 0x80020000.

77124C47 mov eax,dword ptr [eax-4]

This is a lovely error that crashes VB6 if you make a little typo, and here’s how to fix it:

If you make write code like this

 Dim rsProduct As New ADODB.Recordset

 sql = " select *  from orderlines "

 rsOrderLines.Open sql, DSN

 Do While Not rsProduct

  ‘ process rsProduct

  rsOrderLines.MoveNext

 Loop

The application will compile, But, note that I have accidentaly ommitted the ".EOF" in the while loop. This causes VB6 to crash with the above error. To Fix it, use the EOF.
