• .NET Development The underlying connection was closed

  All, I have done plenty of web searching on this and have found a lot of hits, but only one or two hits that were usable. I modified my code according to the advice but I'm still having a problem. I have a C# dll running on a powerful server (Windows 2000 Server is the OS). The C# dll is called by many other programs, often simultaneously. The C# dll simply establishes an https connection to another server, posts some string data, and retrieves a response. The problem I'm having is that under heavy usage (like 6 or more instances of the dll loaded in memory and all trying to post to the remote server), I start getting the following exception: "Error: The underlying connection was closed: Unable to connect to the remote server." ...Show All

• SQL Server Top-Variable-Case

  Hi, I have something like the following in a stored procedure. SELECT DISTINCT top @rowCount a,b,c FROM tblA ORDER BY c DESC The @rowcount value is passed in by the user to the SP. It can be 0 or >0. Do I need to write two queries - one using the TOP keyword as above and another with no TOP as follows: IF @rowcount>0 SELECT DISTINCT top @rowCount a,b,c FROM tblA ORDER BY c DESC ELSE SELECT DISTINCT a,b,c FROM tblA ORDER BY c DESC Or...is there some other construct (such as CASE - which I tried but couldn't get to work) that can handle this condition-check from within the query Thanks much. I suppose there is always the "old fashioned way". set rowcou ...Show All

• .NET Development CPU problem for multiple TcpListener's running on separate threads?..

  I have a Windows Service which runs multiple TcpListeners, each on its own thread (approximately 200 concurrently). When I am running the service on my dev machine (XP Pro SP1), regardless of the number of client requests at any given moment, everything is fine. But on the other servers which have Windows Server 2003 Web Edition SP1, the same service sometimes consumes 100% CPU for half a minute to half an hour when there were NO requests from clients. This happens both in production (Release configuration) and when I run it in Debug mode from VS 2003 IDE. Then CPU usage drops (again, without any obvious reason), and can go up again in a few minutes. There is no pattern in that behavior. There are no other programs running on thos ...Show All

• Visual Studio Express Editions Clipboard Help

  Hello all, good morning :) need some help with this one please: I have 6 textboxes on my form. I need to assign each textbox with a shorcut key (eg. alt + 1, atl+2 etc..) and then copy the contents to the clipboard. I take it that I would have to put the code in a timer event & would the shorcut keys still work even if the form is not displayed on the screen Thanks, Stuart I would imagine that you feel you've clearly descibed what you want and perhaps I'm just dull, but it's still not clear to me.

• Visual Studio Tools for Office Drag and Drop Outlook Contacts with specific items (FullName, etc.)

  edit (11PST 1-5-07) : OK! I figured out how to access the type as an outlook object for the DragDrop but my problem now is that it's just seeing the NeameName.msg that is the dragged contact as Text rather than an actual object (Microsoft.Office.Interop.Outlook.ContactItemClass). Anyone have any ideas how I can cast the data rather than just checking to see if it is that type for the DragEnter private void onDragEnter( object sender, DragEventArgs e) { if (e.Data is Outlook. ContactItem ) { e.Effect = DragDropEffects .Copy; } } original: I am trying to drag and drop an outlook contact onto a form so that the code grabs each object within the contact (FullName, BusinessAddress, BusinessAddressCity, BusinessPhon ...Show All

• Visual C# Problem with slow screen update

  I have a few winforms that are occationally being populated with data-intensive charts. I am experiencing problems with slow respons, and I think the root cause is a slow screen update that is handled outside my code. While other windows paint almost instantaneous, my windows form may need up to 3 seconds before it's back in shape when I toggle between this form and for instance Internet Explorer. I figure it has something to do with how .net redraws the form, because no code is running in my application when the subject winform is being refreshed. It may seem like .NET, CRL or whatever is rebuilding the form from scratch every time I have visited another window. In the same "spirit" the form has a similar response time when I am ...Show All

• Visual Studio Team System Visual Studio has hung. What is it doing?

  Hi, I have set up a new VSTS4DB (sorry if that's the wrong nomenclature) project and am importing an existing schema into it. That schema* has over 1500 tables in it. It has successfully created over 11000 files under the project folder and they all have a Last Modified Date of approximately 12 hours ago. Since then Visual Studio has been in that oh-so-lovely "Not Responding" mode. CPU utilisation is consistently about 50% and it is devenv.exe that is using it - so its definately chugging away at something. Some extra info: My project is part of a solution that is managed by Team Foundation Server We use TFS source control so once it has finished what it is currently attempting to do I shall be attempting to add all these ...Show All

• Smart Device Development /f 3 no go on CLZ - 0xC000001D (v2 beta)
