• Matt Lin Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))

  I'm having issues figuring out how to get my application set up properly so it will authentiate correctly. I need to be able to use windows authentication (all access is internal to the domain) so that the user's credentials will be used to access an external resource. I've looked at the dcomcnfg but am now sure what needs the access updated. The com object that I"m attempting to use isn't listed there so I'm guessing there is something else I need to update. The server is Win2k3. Here's the error from the event viewer and the error from the page: Event code: 4011 Event message: An unhandled access exception has occurred.

• BillyB Serialisation fails when using generic collections. Feedback 119402.

  There appears to be a bug in VS2005 which prevents generic collections from being serialised properly. Specifically, whenever any trivial change is made to the source code, causing the version revision to be changed, a mismatch occurs between the program and the serialised data causing a FileLoadException to be thrown. This only occurs if a) the serialisable object contains a generic (template) collection of non-simple types, b) the assembly has a strong name, and c) the assembly version revision number is defaulted. I have a simple test program which demonstrates this. The workaround seems to be to not put generic collections in serialisable classes. This, however, poses a major irritation for us as we are about to go to market with a pro ...Show All

• Kea GetRunningObjectTable in .NET 2.0

  Apparently GetRunningObjectTable is a new supported method in .NET 2.0. It is accessible via IBindCtx.GetRunningObjectTable and the signature is given as... void GetRunningObjectTable ( out IRunningObjectTable pprot ) Which of course implies that IBindCtx is a supported .NET 2.0 interface too. This is good. We don't have to bother with all that tedious P/Invoke stuff. So... ... does anyone have any ideas on how to get hold of the .NET 2.0 object that implements IBindCtx (because the MSDN certainly doesn't give us any clues!) Cheers, ~swg Well, that's fair enough. If there's no managed object then there isn't. Thanks for the info. Re: your final comment, I didn't draw the conclusion that ther ...Show All
