Visual Studio Express Editions Sifting through array for matches
Hello all, Sorry for such a beginner question, but I can't seem to work through this. I've thought about it for a while, and I just can't seem to figure out a solution. Sorry in advance: I've got an array with a bunch of names in it, and I want to sift through it to make sure that none of the names are the same, and if they are, then I want to take out one of the matches from that pair. So for instance, if i've got an array that contains the names: Robert Rob Jacob Jack Jacob I want to be able to go through and find that second jacob to take it out, so that the array only contains the names Robert Rob ...Show All

Software Development for Windows Vista Workflow Startup in transactional way...
Hello, My WWF usage scenario requires me to startup workflow in a transaction - that is workflow should start, it should be persisted and then my startup procedure completes making completed() vote in bigger transaction. I was thinking about following solution: Let's assume that MyStartWorkflow() should work in transactional way. MyStartWorkflow() starts up workflow using workflow runtime and hangs up on an event (for example AutoResetEvent). First activity in the workflow is marked as PersistOnCompleted what causes PersistenceService to persist workflow as started and with first activity completed then, the event is fired and tr ...Show All
Visual Basic Thread Debugging
Hi, I am currently developing a multithreaded network app, debug output shows a couple of first chance exceptions, however if an exception occurs that is not first chance i.e. bad mid() statement, the ide just freezes for a few seconds, no pop up and i cant trace through the app. What am i doing wrong I have disabled Just My Code, although i doubt this would affect the debugging of my code as it is all managed anyway.

Visual Studio Team System Project Portal discussions: Can I have "New" ones opened automatically
The project portal is a windows sharepoint site. I've placed the General Discussion web part on the home page to make the accessible and useful to the users of our project portal. I've displayed them in the Threaded viw and the threads are all collapsed. That's the good part. When people post new messages to a trhead, those messages are marked witha very used "New" label. The question is, can I get sharepoint to expand all threads to the point where New messages are visible. Because these New messages are hidden in the default view. Teh trheads are all collapsed and there is no indicator that any activity is taking place i ...Show All
