• .NET Development IoCompletion handle

  Hi. I'm not sure this is a right topic for that section. I have a problem with growing number of IOCompletion Threads. In our producion environment we have from time to time ExecutionEngineException. I was trying to understand what is going on and started from analysing DUMP file. I found that there are more than 1000 thread doing IOCompletion operation: 103 76 528 084fe878 880b220 Enabled 00000000:00000000 0014d518 0 MTA (Threadpool Completion Port) the stack of the each of them is: 0:044> ~103e k ChildEBP RetAddr 0e4af0f8 7c90e31b ntdll!KiFastSystemCallRet 0e4af0fc 7c80a746 ntdll!ZwRemoveIoCompletion+0xc 0e4af128 79f2f30a KERNEL32!GetQueuedCompletionStatus+0x29 0e4af194 79ecb00b mscorwks!ThreadpoolMgr::CompletionPo ...Show All

• SQL Server The request failed with HTTP status 401: Unauthorized.

  Other postings I know have asked about this error message, but none has quite been my particular experience. Using Visual Studio 2005 I have developed an aspx (.NET 2.0) web page, which has embedded in it, a Report Viewer object. Clicking a button calls the Reporting Services report and populates the Report Viewer object. This web-page works fine when run from Visual Studio. Once deployed to the Web Server however, the web page produces the 401 error message. I can also run the report fine, when running it directly from the Reporting Services Report Manager, so I know I have the proper permissions on RS itself - it fails only when I try calling the report from the ASP page. Any help greatly appreciated. Thanks, Mike. ...Show All

• Visual Studio 2008 (Pre-release) UdpSample not Working with July Ctp

  I tried the TechnologySamples_Extensibility_Transport_Udp.zip from the official Samples. It isn't working out of the box. There is a third listener Createt with an empty context.ListenUriBaseAddress. If i intercept the UdpChannelListener Constructor, and set that empty Iri to some default it is working. Where does this empty uri come from This fix didn't make it into the July CTP. You need to modify the UdpChannelListener ctor and add the following to the end of it. This empty URI comes from the client-side listener under Composite Duplex. Uri baseAddress = context.ListenUriBaseAddress; if (baseAddress == null ) { if (context.ListenUriMode == ListenUriMode .Unique) { ...Show All

• SQL Server File system error: The background thread running lazy writer encountered an I/O error. Physical file

  Hi All, Anyone encountered this kind of error: File system error: The background thread running lazy writer encountered an I/O error. Physical file: \\ \D:\OLAP_DATA\Project88.6.db\Dim Service Dim Std Sub Key.0.dim\677.Hierarchy 5.Subkey Only.lstore. Logical file: .

The resolution to this error was to restart analysis service then process update the dimension. Any insight on this will be appreciated. thanks Please contact Customer Support with you situation.

• Visual Studio 2008 (Pre-release) Suggested WPF 3D Resources

  I recently started researching 3D programming in WPF. I read over the high-level SDK docs and played around with some samples, but I don't have a lot of time to tinker with it. I'd appreciate it if some people who have solid WPF 3D experience would take a moment to provide me with some links to resources that you feel are "really good" for getting started. Keep in mind that I don't have any 3D programming experience, so it's a whole new world for me. :) Thanks for any help. charles petzold's chapter 32 is also good http://blog.krisvandermast.com/ct.ashx id=609cef16-a8ef-41e2-9d3f-7c7cd3b7bbb9&url=http%3a%2f%2fwww.charlespetzold.com%2fwpf%2fChapter32.doc ...Show All

• Windows Forms MDI windowlist formclosing bug

  Hello, In my application, I have an MDI parent form and several MDI child forms. Wanting to allow the user to click the X on the child window and hide the window rather than close it, I implemented the FormClosing event handler as follows: if (e.Close Reason == CloseReason.UserClosing) { e.Cancel = true; Hide(); } This does hide the child window but when the user opens the window again, the windowlist is never populated again for that window. It is undesirable for my application to make new instances of the child forms each time one is displayed so instantiating a new form instance when I want to show the child form is not the solution. The code in the parent window to display the child windows does this: myForm.MdiParent = this; myForm. ...Show All

• .NET Development Problem with underscore prefix on attributes

• SQL Server Telco Cube

  I am building a cube for a telco company. There is among others a subscriber dimension and a handset dimension. There is also a dimension to indicate a handset switch. In the source table, this is a flag set to 1 in the month where the switch occurs. I have added this as a measure to count the handset switches and also as a dimension. Other measures are a count of the subscribers and their revenue. I have added a calculated measure to know the average revenue per user. Now I would like to add a measure to know the average revenue before a handset switch and after a handset switch. Is there a way to calculate the average revenue for all months until the handset switch measure has a value and to calculate the average revenue for all month ...Show All

• Visual Studio 2008 (Pre-release) TreeView & HierarchicalDataTemplate

  Hi, I am using HierarchicalDataTemplate to bind my TreeView to list a set of directories. In our applicatoin, we have a favorites menu, from which user can navigate directly to a particular node in the tree. I got the logic to get the active item. But I couldn't set it to the SelectedItem or SelectedValue of the TreeView as they are readonly properties. Is there a way to hack this or this is not possible in WPF with HierarchicalDataTemplate. Please help me, this is blocking me to go further.
