• Visual Studio Team System Processor time

  I was doing load testing of the web application When i kept a constant load of 300 users with connection pool of 50 i was getting threshold violation in the processor time.when i kept on increasing connection pool the threshold violation was also getting minimized...as soon as connection pool reached 250 the threshold violation was also removed... Now if i keep Load =200 users and connection pool = 50 i donot get this threshold violation why is it so and what does that predict.. Processor time is not typically closely correlated with connection pool size, so I think something else must have been going on. Certainly if 300 users were using up too much CPU time on the client or server, then 200 users ...Show All

• Visual Studio Express Editions Inline assembly in VS C# Express ?

  Hello. I could use some help right about now. I'm writing a command-line Application for loading a bmp image, processing it, then controlling a CNC (Computer numerical controlled) mill, based on the info in the bmp image. Now, the problem is that I need a bitwise access to the data. and I can't find a "BIT" level type, and neither operators at that level. What I currently do is : I read a byte, (Or several) from the bmp file. (After loading the bmp header into an object of my own creation). I then load these bytes into an array. However I find it kind of hard to manipulate this array in a correct fashion to display and edit what I want. Current array is of type int[][]. What I would like is a "Bit[][] array". That would ...Show All

• Visual Basic How do I determine how much ram a program will use?

  -Visual Basic Express 2005- I'm working on a very large accounting program that requires a few hundred variables. I'm declaring most of them publicly. Is there any information that tells how much ram strings, decimals, int16 and others take Also is there a limit to how many variables I can publicly declare in a module Thanks in advance A few hundred variables !!!! , With this figure you are unlikely to encounter anywhere near the limitations of that exists. No real world limits to the number of variables you can declare in a module, I'm sure that there is a number but its probably such a large figure that its really not a limitation and the limitation is probably not on the module but rather at the process level. As far as ...Show All

• Visual Basic Right place for this?

  I am not sure if this is the right place for my question, so please redirect me if need be. I am having trouble with my version control system because whenever I rebuild my deployment package in my solution, the Release directory is deleted then recreated and the new .msi and setup.exe are created. My version control system (SVN)keeps a hidden directory in each directory and that is need to keep track of what was checked out etc. So everytime I rebuild my deplyment project I end up having to move the new installable files to a saev directory, check out from SVN, copy the new .msi and .exe files back to the release directory and then check them in. Is there some way to stop Visual Studio from deleting the Release directory so SVN c ...Show All

• Windows Forms Changing the databasource of a DataGridViewComboBoxCell at runtime

  Hi, I have a DGV where one of the columns is a combo box style. I bind this combo box to some datasource. What I would ideally like to do it to limit the combo selection to make the items available mutually exclusive to what is in other rows. The net result I guess is I get uniqeness in this column over all rows. Is this possible If so, which event should I use to re-assign the datasource property for the combo Thanks for your help Graham Oh dear. I left this bit of code for a week or so because I had to attend to something else. There is still a problem, but this time I think it is to do the DataGridViewCell / Column rather than the binding list or data table I'm using. The filtering ...Show All

• SQL Server Package variables "disappear" from job properties

  Creating a SQL Agent job to run a package works just fine. On the Step Properties, Set values tab, I can add variables and the values I want for them, no problem. The job runs just fine.

• Visual Studio Where can I put .targets files

  Where can I put .targets files so as they can be easily imported into a project file Presently I'm adding my .targets files to the .NET installation , C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727. I'm doing this from an installer and my worry is that the version number will change. The reason I'm using the .NET installation location is because the project file has use of the MSBuildBinPath property <Import Project="$(MSBuildBinPath)\InstallationLocator.targets" /> Are there any more useful properties out there that maybe of some use to me an MSBuild property that points to a location which may never change!!!
