VistaDB 2.0 and XP SP2
Error: "Method not found"

Sept. 7th, 2004

Follow up: RC3 has fixed this issue.

We have received many reports about people using VistaDB and seeing an Error message "Method not found" .

Turns out that this error is caused by the Windows XP SP2 update. A big thanks to several users for staying on top of this and helping us with testing (Jason Short, John Campion and Richard Cleaver).

Our initial thought is that we will need to change the engine API protocol to handle moving PChar values a bit differently. Currently, VistaDB passes PChars from the engine directly back to .NET (Provider and DDA). And now with XP SP2, this style of passing PChars may be considered "dangerous" and therefore XP is not allowing it. Again, this is our initial though and is not yet clear if this is in fact the solution.

We are allocating the rest of this week to resolve this important, along with finishing work on a couple of other items. With this, we will try to get RC2 released ASAP which means Friday may be the earliest. Furthermore, we are allocating a bit more time for the full 2.0 release to allow for testing due to the upcoming changes.
