    End Sub

Error BC30456 'Dispose' is not a member of 'Object'. halpasAdv230620

The above error came out of nowhere all of a sudden after many hours of development with error-free project development code. I am baffled as to what is causing the above error along with 30 other errors referring to the following: BC30469 Reference to a non-shared member requires an object reference

Please keep in mind that my project was working smoothly as I was making modifications and I was about 80% done with my program's functionality when these errors just suddenly appeared. I intuitively guess that I must of accidently, inadvertently, deleted an unknown stray obscure part of the code which triggered this current plague of errors.

Please help as I have taken a considerable amount of time trying to troubleshoot this to no avail.
