• .NET Development Why doesn't Garbage Collect reclaim unreferenced objects???

  I have written a Windows Service using VS.NET 2003 C#. The service is having big memory foot print problems at a customer site. This service communicates via TCP to about 100 clients on the customer's network. The service has a single TCP listening thread (that derived from the TcpListener object). When a new TCP connection is accepted by this thread, a new client thread is instantiated and a Socket object is passed to this new client thread. The client thread is then responsible for all comminications with the customer's client machine. There are about 100 client thread at this customer's site. The messages that are exchanged with the customer client are XML based. In each client thread object, I have a single method that process ...Show All

• Visual Studio Team System Unable To Share Files With Team Foundation

  How can I share code files between projects using Team Foundation source control   We currently share code files between projects using the full framework and the compact framework.  VSS has the ability to share, branch, and merge.  TFS only allows branch and merge. When you say 'remove this feature', I'm assuming you're talking about comparing VSS to TFS - as we've said elsewhere, sharing was never designed for TFS. The difference between sharing and the common alternative approach (branching) is that you have no choice but to propagate the change you made in the shared file from one solution to a sibling (as you phrased it). As project/team size increases, this inevitably causes more proble ...Show All

• .NET Development OutOfMemoryException from nowhere

  I created one desktop application. On some machines if works perfectly. On another - have OutOfMemoryException without visible reasons from many locations. For example 2Gbytes free and OutOfMemoryException at ArrayList.GetEnumerator(). It seems like something limit memory. So my question is: Can .NET Framework limit desktop application memory usage How that limit can be changed or turned off OOM is usually thrown on a box, newarr or newobj. The GC is always getting requests for allocations and has to compete for Virtual Memory (new segments are allocated through VirtualAlloc) CLR itself makes native allocations as well for jitted code, datastructures the CLR needs (including the ones that GC n ...Show All

• SQL Server Optimize speed of Hosted SQL Server

  Hi, I'm retrieving data in VBA using simple SELECT statements on my Hosted SQL Server. How do I most effectively speed up the process Is it just about data amount, traffic, and speed of Internet conncetion Or should I use Stored Procedures or should I index tables Is there a function to kind of "flush" the data to the VBA program as it is all READ-ONLY Any help is much appreciated, Jakob Would it be possible to run the queries against a local SQL Server that runs on your laptop. That way, you can ignore the network latency, and see if the query is causing the problem. If you use RecordSet, it will keep the connection open until you explicitely close it. Even when you close it, c ...Show All

• Visual C++ warning LNK4248: unresolved typeref token (01000017) for '_TREEITEM'; image may not run

  When compiling my program which is a windows app and not a DLL, I get this error message under Release mode but not in Debug. Furthermore I can get rid of the warning if I don't use managed extensions (remove \clr) in the project properties. Is there not some releases source code from Microsoft to allow the _TREEITEM and _IMAGELIST object to run in managed extensions I thought the goal from MS was to have us use the managed extensions and therefore I would think that this situation would have been resolved a long time ago. I've read the link where this exact same error is generated with a DLL but this is a standard windows app and therefore doesn't have a DLLMain code. http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=7750 ...Show All
