• Visual Studio Team System Load Test requests/sec drop to zero

  I'm seeing a recurring problem in a load test where requests/sec drop to zero during the test, and then resume normal levels 1 minute and 15 seconds later. The load test has 25 users, starting at 1 and ramping by 3 every 8 seconds - it consists of 2 webtests. I reach a constant user load and everything cranks along pretty well until about 30 minutes into the test. Then requests/sec drop to 0. I don't see any corresponding spikes in any other counters - just % processor on the servers also drops to 0. Every time I re-run the test, I see the same type of behavior, but ...Show All

• Visual C# How to develop a password protected Windows Application?

  Hi all, I am trying to develop a password protected windows application. All that I require is a simple prompt for password whenever the application is started. The program should be able to detect if the application is started for the first time. If it is, the application should prompt for the user to set a password instead. If the password is correct, then the application will go on to show the starting startup screen. I am not really sure how to start or go about creating this application, i.e. password protected part. Q1) How do I store the password that is set. Do I create a static variable string and store the password using this stat ...Show All

• Visual C# VS.NET 2005 RC1 -- Is clipboard ring missing from IDE?

  It used to be one of my favorite features! Formerly, from the C# (for example) code editor in the IDE, open the 'Tool Box' tab, and there was a stack of all the things you'd put on the clipboard while editing.  I can't seem to figure out where it went too...hopefully not the bit bucket... TIA, Howard Hoffman I dont think the feature is completely off the IDE. All you need to do is switch back to Code Editor and make the Toolbox visible. Now copy the text you want to work with and in the toolbox, right click and select Paste. This could be repeated. The only thing that have got eliminated is the tab 'Cl ...Show All

• Visual C++ VC2005 %50 Slower then VC2003

  I just migrated a graphics application from VC2003 to VC2005.  After building it, I ran a small benchmark & found that VC2005 code was about %50 slower. The Application does a great deal of floating point and integer calculations.  It also converts doubles to int quite a bit (the VC2003 version used SSE to handle this). The VC2003 version used /G7 and /Ow (which are not available in VC2005) Compiler Switches Used: (vc2003)/arch:SSE2 /c /EHa /FD /GF /GL /Gs8192 /Gy /MT /nologo /O2 /Ob2 /Og /Oi /Ot /Ow /Oy /TP /W3 /WX /Zi (vc2005)/arch:SSE2 /c /EHa /FD /G7 /GF /GL /GS- /Gs8192 /Gy /MT /nologo /O2 /Ob2 /Og /Oi /Ot /Oy /TP ...Show All

• Visual Studio The definition of Triangle and Rectangle shape in Domain Model.

  When I look at the "Relationship" in the Domain Model, I see two sorts of shape, "Triangle" and "Rectangle". What do these two shape mean And why do we use "Triangle" and "Rectangle" to denote these meanings Thanks alot. Each shape represents a role of the relationship. The choice of symbols was orginally to show the direction of the relationship from source to target, but it is redundant because the layout achieves that. The notation will change in the replacement for the domain model designer which should appear in the next release. ...Show All

• .NET Development Help with Event Handling

  Hi all, I have understood how to manage events in VB.NET, but I can't figure out with this problem: I have a function, wich has to return me a string. When I call this function, some data is sent to a serial port, then I have to wait that the serial device processes it. To do this I have registered an event, managed by an eventhandler. The problem is that I don't know how to return the processed data. Once the event is catched, what have I to do inside the handler sub It would be great a behaviour like: Dim dataThatIWant as String = Called_Sub() ... public function Called_Sub() as String 'Send data to rs232 device 'Wa ...Show All

• Visual Basic Real Time Data Monitoring

  Hi All: I am writing a project to analyze data from a device in real time. The idea is to pick up the signal from a sensor through serial port in 20Hz and to do some calculation on the data received, and plot out the result on the form. I use a background worker to read data from the serial port and do the calculation within a Do Loop. There is no problem on this. My problem is that when I try to use GDI+ to plot the results on the form, data are not refreshed instantly on the form. I use a Collection of Single to store the data for plotting. Questions are: 1. Can Vb2005 do the job Or VC2005 is better 2. Is there a control ...Show All
