• SQL Server Strict Transaction Nesting Bug with CLR

  Dear all, I am constantly running into this error when calling CLR functions from triggers (even when the triggers are CLR functions themselves): The context transaction which was active before entering user defined routine, trigger or aggregate "[name of CLR sp]" has been ended inside of it, which is not allowed. Change application logic to enforce strict transaction nesting. However, there is no cyclic nesting going on here. In fact, the error only appears when the CLR function is writing to the database. Only executing SELECT statements inside the statements doesn't freak out the SQL server (2005 SP1 in my case). I am not ending any transaction at all. This error shows up in many places: as exceptions from ASP.NET web pages, ...Show All

• Software Development for Windows Vista System.Speech.Recognition - my code works in XP but not in Vista RTM?

  Hi all, I have some code that I converted to use .NET 3.0's System.Speech library. The resulting assembly executes and recognizes my speech fine in Windows XP SP2. Running the same assembly in Vista RTM however doesn't work. The SpeechDetected event fires, but the Hypothesized, Recognised and Rejected events never fire. It isn't a microphone / soundcard issue because the "start listening", "start notepad", "mousegrid" commands all work fine in the Vista RTM install. Googling around only seems to turn up Beta2 samples and the Windows SDK samples only have TTS samples - no recognition ones. Below is a code sample for how I am initializing the SpeechRecognizer class. It is a command interface ie: I supply an array of strings th ...Show All

• Software Development for Windows Vista USB Video (UVC) extension unit

  I am having difficulty accessing UVC extension units using DirectShow IKsControl::KsProperty. When I try doing KSPROPERTY_TYPE_GET | KSPROPERTY_TYPE_TOPOLOGY on PropertyId 0, I get back the extension unit GUID and six additional bytes (1,1,3,2,1,0,6) which do not seem to be defined in the DDK. PropertyId 1 returns error 0x80070490. Any suggestions The data for KSPROPERTY_EXTENSION_UNIT_INFO (PropertyId = 0) is copied over from the device's extension unit descriptor which is cached during device startup. During startup, the driver issues a number of control requests to the device like GET_INFO, GET_LEN, GET_MIN and GET_MAX. The value returned by GET_INFO tells the driver which of GET and SET requests are v ...Show All

• Software Development for Windows Vista How to invoke a web-service specified at runtime ?

  I have an activity that discovers the wsdl of a web service based on some input parameters, and then I want to use the WebServiceInvokeActivity (or a custom invocation activity) to call that specific web service. I do not know exactly what the wsdl is at design time (perhaps I can force the web service to have a specific method name and parameters, but I find the location or service provider at runtime). Is this possible How Thanks if you choose the custom activity way of working, this can be interesting to generate the proxy at runtime: http://www.thinktecture.com/Resources/Software/DynWsLib/default.html Serge ...Show All

• Visual Studio Tools for Office Outlook Doesn't Load VSTO add-ins

  Hello, I've been working on a VSTO outlook add-in project in C# for a couple of months now. Just recently ALL outlook projects have stopped loading in outlook. When I run the debugger Outlook starts but the breakpoint in the ThisApplication.Startup event is never reached. When I go to Tools-->Options-->Other-->Advanced-->Com Add-ins, my addins are registered but unchecked. When I check and hit ok, nothing happends, I reopen Com Add-ins and they are still unchecked. I get no errors of any sort. I have set the VSTO_LOGALERTS and the VSTO_SUPPRESSDISPLAYALERTS environment variable to 1 and 0 respectively. I have also put an installer class into my project that should run on install but does not seem to do so. This installer class ...Show All

• Visual Studio Express Editions Form applications and console output

  Hi all, I just discovered that I'm not able to print anything on console from a project created as Win Form application. No printf(), no cout<<, neither Console::Write() works. The program is launched from a cmd.exe window and works, but some messages printed on the console never appear. Should I have to change some project settings Thanx Have a look at the Win32 API AttachConsole. You should find samples in MSDN and I bet there are some to google or search.live for. -- SvenC ...Show All

• Visual C# Returning an array

  I still need help understanding what is happening here: class ParamArrayWithReturn { public static void Main() { F(3, 2, 15); } public static int[][] F(int n, int m, int value) { int[][] x = new int[ n ][]; for (int i = 0; i < n; i++) { x[ i ] = new int[m]; for (int j = 0; j < m; j++) x[ i ][j] = value; } return x; } } I see that we are going to dimension array to 3 indexes. Then I see what happens after that is that we then create two internal array indexes inside those 3. I also see that in this case, we will end up having the value of 15 at each index. I believe it will look something like this: 15, 15 15,15 15, 15 Now why would we return x here And what happens to it when it returns to the method call I am confused by that part ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. XBox 360 controllers for the PC

  Hi, I had a question about controllers that plug into the PC. I understand that only XBox 360 controllers are supported by XNA. I also understand (I think) that wired only controllers work as they need to be plugged into the USB port on the PC. Actually the last point is now not valid since I discovered the wireless controller for Windows and 360. But this isn't available until 2007. Does anyone know if this wireless controller is an actual controller or just a receiver for an existing wireless controller Cheers, Steve Anyone know if I can use my Wireless XBOX 360 controller with the Play & Charge kit plugged into my PC USB slot Or do I really need to go buy a wired Xbox 360 controller ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. rendering shapes on terrain

  I am trying to render a circle representing an objects movement radius value in my level / terrain editor and im trying to figure out the best way to handle this. I've been thinking about using the stencil buffer to cut out an outline of a sphere at the objects position and then render my circle there, but im not exactly sure if this is the best way to do it. Does anyone know a good way of doing this right now im using a sphere as a shadow volume and then rendering the shadow as my circle on terrain and it seems to be working well, except when the camera goes into the shadow volume. its not a major issue and i guess i can do carmacks reverse, but it seems to work alright now if anyone has any better sugges ...Show All

• Visual Studio Team System Branching Strategy For Dynamic Environment

  I am working in a very dynamic environment where several different features and bug fixes are worked on simultaneously by many different developers. The project is a large public facing website that must have bugs resolved quickly and has constantly revolving promotions. We are having a problem deploying changes quickly when some technical features may take weeks to develop while other minor ad campaigns may take only days to develop. So I was thinking that an environment like this would benefit from each developer having a private branch. and then merging in chages to the main branch when a feature was complete. I set up a prototype of this environment and private branches seem very clunky in Team Foundation Server. I have seen many peopl ...Show All

• Visual Studio Express Editions How would I go about putting my class libraries into a specific namespace?

  I know that in C#, we can enclose our code inside a namespace: namespace <namespace name> { class Customer { ... } } Let's say I want to have a top level namespace that indicates our department. Dept And then I want to have lower level namespaces to group our common library code. For example: Dept.TimeUtilities Dept.MathUtilities Is it possible to have two developers working on some code to add to the TimeUtilities namespace -- each working with different source code files For example, developer #1 works with: namespace TimeUtilities { class Time1 { ... } } And developer #2 is working on another source file with: namespace TimeUtilities { class Time2 { ... } } Does the definition and implementati ...Show All
