• .NET Development Simulating hardware faults

  Hey, I'm trying to do a project where I'd like to simulate 'hardware faults' that occur during the execution of functions from the base class library. Basically, during the execution of a method, I'd like to flip a bit in the memory that the method is using. I've been looking around and have found nothing on how I might be able to do this in the base class libraries because I don't have access to their source code like I do for my own methods. Anyone have any ideas Thanks, Michael It's not that hard. Just starting a .NET program is enough to generate several hundreds of page faults. It just happens that there is code around that puts a pretty little bow on top of that fault, doing the &q ...Show All

• SQL Server Newbie questions on processing cubes

  A few months ago i overtook a datawarehouse solution in our company, as the developer that was in charge of it decided it was time for a new job...I had never seen this Analysis Services before, so it is quite a challenge to know what exactly is happening here... The issue is we have around 13 cubes and 20 dimensions or so, and some dimensions are shared among cubes... The whole database containing cubes/dimensions is processed daily and this takes 6 hours!! I can see the previous developer just made a quick SSIS Package with a SSAS Task in which he just chose the database and its selected as process full... Thats all... Here comes some questions then: 1- Is this optimal at all, or is there a better way of updating our cubes The i ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Scorched Tanks for Windows (and 360)

  Hey, Continuing my habit of starting more games/projects than I can ever hope to finish, I decided on Thursday I'd write my own version of Scorched Tanks in XNA. What I've got so far is by no means close to being a game, yet, you could probably "play" around with it for 5 minutes or so, so call it what you will. It's working on 360 and Windows (without code changes of course) which is good news. What I've zipped is really just a work in progress for people to play around with and ask any questions (should there be any). The code is, as with all works in progress, fairly atrocious, so I'll keep it to myself for a bit but if by a miracle I've done something and you want to know how I'll happily tidy up the relevant bits and post it. ...Show All

  Does anyone have a code snippet that shows how to send mail from c# Not that everyone cares, just that maybe one or two do.

• Visual Basic Do nothing in a while loop

  I have a while loop that runs until one of two conditions are met. 1) A timer elapsed 2) A COM object raises a event that is done doing a task This works great but while the program, it's a window service, is running, it utilizes 50% of my CPU power. How can I make the service do nothing when it's in the while loop My code: With Timer1 .Interval = maxTime * 1000 .Enabled = True Dim i As Integer Do While Not ReadyState And .Enabled i = i + 1 Loop .Enabled = False End With that is bad design. It will take up the CPU as you have mentioned because there is nothing to do/its going fast in the loop. you can add a Thread.Sleep(200) to sleep the threa ...Show All

• SQL Server Closed conversation endpoints not being purged

  We have been having a problem with service broker for quite a while now and searching on these forums and more generally on the web has not yielded any kind of answer... Our application utilises service broker within a single database (there is no cross database, cross instance or cross server communication). There are approximately 12 queues which are used to varying degrees. A few of the queues have a throughput rate in the order of up to 100s per minute at peak periods. In some scenarios we are able to make use of persistent conversations but the majority of messages are sent on their own conversation or in small batches on their own conversation. Some time ago we found that the database was growing in size more than expected d ...Show All
