• .NET Development Stuck with UdpState

  Can anyone help me with a problem I'm having trying to get UdpClient.BeginReceive working I've been trying the example given on MSDN, which gives this section of code to use: public static void ReceiveCallback(IAsyncResult ar) { UdpClient u = (UdpClient)((UdpState)(ar.AsyncState)).u; IPEndPoint e = (IPEndPoint)((UdpState)(ar.AsyncState)).e; Byte[] receiveBytes = u.EndReceive(ar, ref e); string receiveString = Encoding.ASCII.GetString(receiveBytes); Console.WriteLine("Received: {0}", receiveString); messageReceived = true; } The part I am having problems understanding is the first two lines... UdpClient and IPEndPoint, more specifically the UdpState part of them. I can't find UdpState anywhere, so I came to the conc ...Show All

• Visual C++ Cross Session Activation Moniker

  Hi All, I am trying to develop an application that communicates with users in different sessions (on terminal server) on the same server via invoking a COM server in different terminal server sessions by using the session moniker (http://msdn2.microsoft.com/en-us/library/aa383539.aspx) it works fine when the caller and sessions in which I invoke the COM server are same, if I try to invoke BindToObject on a different session it fails with "Access Denied". Is that the desired behavior, the above mentioned article doesn't mention that. Would like to know your opinion about it. I am testing on a win2k advanced server.

• Visual Studio Express Editions ISO file for SDK

  So, I decided to burn a CD. I downloaded what was billed as an ISO image: http://www.microsoft.com/downloads/details.aspx familyid=E15438AC-60BE-41BD-AA14-7F1E0F19CA0D&displaylang=en First off, is that the correct latest and greatest The file that got downloaded has a type extension of .img , not .iso as I expected. My burner (Nero) does not recognize the extension. What's up with that I was able to make a CD of VC++ Express with no problem. It had a .iso type. Anyone know what I can do with the .img file   Or better yet, where I can get the .iso file Jive Dadson wrote: So, I decided to burn a CD.

• Visual Studio Team System Changing VS edition on a production build server

  Hello, We're interested in expanding our use of VSTS from our current Dev + TFS workgroup setup, to incorporate the Test edition as well. Since we only have MSDN subscriptions for the Dev edition, we're using the Team Suite 180-day trial to play around and see if it meets our needs. Everything's working great on the developer machine side; we've built some tests and are happy with what we've got, but unfortunately, because our TFS build machine doesn't have the Test edition of VS installed, the necessary DLLs aren't installed, so we end up with a bunch of lines like this in our build logs: C:\Program Files\MSBuild\Microsoft\VisualStudio\v8.0\TeamBuild\Microsoft.TeamFoundation.Build.targets : warning : TestTypes\{37e36796-fb51-461 ...Show All

• SQL Server lastnonempty & role playing date dimension

  Hello, I'm just curious if in case of a role-playing date dimention it's possible to somehow tell SSAS to use only one role for LastNonEmpty aggregate Like we have a fact table with a few date related members - such as TransactionDate, DateOpened, DateClosed etc. All measures in this fact table are set to aggregate as LastNonEmpty & everything works just fine as long as only TransactionDate is linked to dimDate. If any other dates are linked then LastNonEmpty doesn't work properly anymore & we get unpredictable results. So if it possible to set ONLY TransactionDate to be used as LastNonEmpty & for all other dates just aggregate as sum Thanks! Look for <MeasureGroups> tag ...Show All

• SQL Server Real World: Backup Strategy and implementation, how?

  Real World: Backup Strategy and implementation, how A quote: “Real World: Whether you back up to tape or disk drive, you should use the tape rotation technique.

• Visual Studio Debugger highlights wrong line, steps over code without executing it

  I stumbled across some rather odd behaviour in the debugger this morning, and it took me a while to realize just exactly what was happening. I've tried to distill the problem down to a compact test case: int somefunction(int x, int y) { if (x == y) { try { x++; // or whatever, doesn't matter } catch (SomeCustomExceptionClass &) { return x; } } x--; return x; } // calling code: somefunction(1,2); If I put a breakpoint on the line "if (x == y)", I can verify that x does NOT equal y, so I would expect the contents of the if block to be skipped entirely. However, hitting F10 to step will cause the debugger to highlight the "return x" line inside the catch block inside the i ...Show All
