• vino-msdba Databinding to a service method...

  Using what seems to be the preferred approach for accessing WinFX services, is data-binding possible There are two approaches, I understand, for handling references to a WinFX service. In the first, you use the "scvutil" application to auto-generate proxy classes. These classes wrap all necessary logic to call a service. There is no direct reference to the service project in your consuming application, and you can generate these ...Show All

  Hi; Asking new because I think this got lost in the message it was a reply to... Just to confirm, if I have run the latest windows update and it shows no updates for Word, then the fixes in KB907417 should be on my machine - correct I have never run the fix in KB907417 and on my dev machine it has version 7.10.5077.0 but my test system, which shows no pending office updates, has 7.10.3191.0.
