• .NET Development IP Address of Win Client

  Is there a way to determine what ip address will be used by a TcpClient In the old .Net to get the IP address some people would use: 1.  IPHostEntry hostInfo = Dns .GetHostByName( Dns .GetHostName());     Which is really bad because it's the DNS info not the real machine info or the IP being used. or 2.  from WMI (if installed)          SelectQuery NAQuery = new SelectQuery ("select * from Win32_NetworkAdapter");         ManagementObjectSearcher NASearcher = new ManagementObjectSearcher (NAQuery); Must guess which one will be used if yo ...Show All

• Visual Studio Team System traceability in Team Foundation Server

  Does anyone know if TFS maintains traceability between requirements, specifications, testing, etc. you can create links between workitems either manually through team explorer, or automatically through event synchs when work items are created (eg when a scenario is created, a number of tasks are also automatically created to support the scenario, and links between these are auto-generated).  Once you have linked work items, then you can use these to create results such as traceability reports eg.  Alternatively, Project can also be used for this, as it has excellent tools for parent-child relations ...Show All

• SQL Server SP not working correctly? when called from app

  Hi In a stored procedure the following code snippet 1 checks against duplicate data being inserted. I've tested it with snippet 2 and it works as expected. However, when the procedure is called from ASP.NET the check seems ineffective. I still get the error msg. The application uses a SqlDataSource with the following parameters. Any suggestions Thanks, Bakis. PS I want to ask a question on the ASP.NET forum .The login/pwd for this forum "get me in" to the .net forum in the sense that when I log in I see a logout link. I don't get an "ask a question" button though. Is there a separate screening for ea ...Show All

• Visual C# TabControls and dynamic tabs

  I have an application that will dynamically add a tabbed page when the user clicks on certain objects in the application. I am successful at adding the tab but I cannot figure out how to call or access the new tabpage. the IDE does not seem to "intelli-type" it. I assume that this is because I dynamically created it. so how can I access and change the properties on the new tabpage Thanks for any assistance. From there how do I access the properites of a specific tab. I need to be able to access them individually. ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Different results between REF and HAL devyce

  Hi! When executing my pixel shader, results are ok. But when I execute with my recent new grpahic card Quadro FX 3400/4400 results are rubbish. Exactly what happens is that! In my pixel shader I have these four operations Output.weights.x = (1-frac2.x)*(1-frac2.y);\n" // 1 float output Output.weights.y = frac2.x*(1-frac2.y); // 1 float output Output.weights.z = (1-frac2.x)*frac2.y; //1float output Output.weights.w = frac2.x*frac2.y; // 1float output Using Devyce_REF results are for example 0.5625 0.1875 0.1875 0.0625 that its exactly what i'm waiting for, but using my grpahic card the results are quite differents : 0.56175613 0.19117355 0. ...Show All

• Visual Studio 2008 (Pre-release) Indigo and Classic VB

  We are tring to leverage WCF in some of our legacy (classic VB 6) apps by wrapping up a .Net component into a Com-Callable Wrapper. So far so good. The only problem is this - when running the app through the Visual Basic debugger in the IDE, it doesn't load the binding info found in appname.exe.config (which does work fine when running the .exe), so the web service calls fail. Any ideas You might also want to consider using the COM+ Integration feature of WCF. It might be able to save you from some manual wrapping tasks. ...Show All

• .NET Development StrPtr in .NET

  Hi, I am making an API call NetFileEnum in an application that I am writing in C#. I have sample caode of this function been called in vb6.

• Visual Studio Tools for Office Some questions about ActionsPane

  Good morning, I have a few questions about the ActionsPane, but I think they won't be that difficult. But let me first explain my project: I need an Add-In for Word 2003, so when starting Word, a custom button should apear. This is already done. Now when click on the button my Actionspane solution should be shown. So I made another project with a Word Template. Now I have 2 projects and one calls the other.

• Software Development for Windows Vista recommend way to do IPC between app and service

  Hi guys, until now I've used (unnamed) Pipes to communicate between apps and services. For that to work I used OpenProcess(serviceProcessHandle, PROCESS_DUP_HANDLE), so that I can duplicate the pipe handle from the service to the app. This still works in Vista with UAP turned off - even from a guest account. But as soon as I turn UAP on, OpenProcess fails with "access denied" - even in elevated mode. I guess that's intended So since my old IPC method doesn't work now, anymore, I'd like to know which IPC method Microsoft now recommends to be used for communication between apps and services. Thanks! ...Show All
