• SQL Server auto expanding Temp DB to fit large requests

  I have run into a glitch in SQL 2000's ability to automatically expand the temp db when temp tables become very large.  In our business it is sometimes required that I alter a customer's configuration data without modifying any of their transaction data.  This requires a rather complex procedure that creates a script of insert/update/delete statements that, when run on a customer's database, modifies their configuration to a replica of our in-house test environment. While creating this script, sometimes a few lines are dropped.  The real problem is that we have no error or indication that the script had dropped lines until we ...Show All

• Visual C# Close 'X' button problem on child form

  Post smallest amount of code of a single Form that reproduces this. By default clicking the x will close the form. All of the child forms have a common factor and that is they all use while loops.  I am collecting a ton of serial data and looping works best.  Does the loop have something to do with it, I would expect the App.doevents() to handle the event correctly when it fires.  Below you will find the constructor, MyForm_Method, which contains the while loop and a timer to trigger the method once the constructor is done. Thank you. public MyForm() { // Required for Windows Form Designer support InitializeCompon ...Show All

• Visual Studio Team System Newbie confusion on TFS and VS.NET. Enlightment needed.

  I setup a TFS Team project (under Beta 3). Next I created a New project (not a Team project) in VS.NET 2005, right-clicked the project name, and selected "Add project to source control". I received the message "The current project must be saved before it can be added to source conrol." Huh I want to save it in TFS and it won't let me do. (I forgot to define a workspace... maybe that's what it wanted. But when I attemped to define a workspace I got the same error message). I finally saved the project to my local harddisk (in folder "deleteme") and was then able to add the project to source control. But now when I ...Show All

  Hello All, I have an application which I want to expire after the trial period and only works after you eneter the key. Any suggestions, piece of code which I can use to secure my application. Thanks, Harsimrat Well, you need to store the date the software was installed, that date needs to stay if someone does an uninstall, and then you may want to write some code that detects if users have been playing with the system date.

• Visual C# Best practice

  Ok, I have a question on what would be the best practice for a translator... If you have 5 languages: English, Chinese, German, French, and Swedish and you have different methods for converting each one into each other what would bet he best practice Heres an example: If you selected Chinese as the starting Language and English as the Ending Language it'll return "zh-CN%7Cen" as the code needed to post. I'm thinking i'll create an enum to store all the languages and then create a struct that takes the enum twice, once for starting and once for ending, and then a value. so i'll have something like struct LanguagePairs { Lang lan ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Running MDX games on other computers

  I've been working on and MDX game for a couple of months in Visual Studio 2005 express; now I'm trying to run it on other computers and it doesn't work. Of the 4 computers I've tried it on, only 1 successfully ran it. The others get a file not found exception that seems to be for a DLL, but when I put a try/catch around the application initialization (this is based on the sample framework) and found the exception, it conveniently failed to include the actual file name.

• .NET Development Using TransactionScope to share transactions between Methods

  Hi, Before we start: This is all taking place on a single database. And I really don't want the overhead of Distributed Transactions. If I want to have lots of separate data access routines that do work on the database. Sometimes I want these routines to take part in a larger transaction. Sometimes they will just be running in their own transaction. I looked at TransactionScope and I thought this would do the trick. I now realise I would need to pass an open connection object in to each routine. TransactionScope takes care of sharing my transaction but it doesn't help me with sharing connections. Becuase... If I have 2 connection ...Show All
