• SQL Server Locks - Isolation Levels

  Good morning, I am trying to get my head around locking (row, table) and Isolation Levels. We have written a large .NET/SQL application and one day last week we had about two dozen people in our company do some semi "stress/load" testing of the app. On quite a few occassions, a few of the users would receive the following error: "Transaction (Process ID xx) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction." We are handling this on two fronts, the app and the database. The error handling in the app is being modified to capture this specific ...Show All

• Visual Basic Need Help: Specifying toolbox icon for a web custom control?

  In VB.NET 2005, how can you specify which icon to display in the toolbox for a Web Custom Control I'm not looking for the project icon. I'm building a web custom control library (DLL). This library contains components that are added to the VS toolbox for ASP.NET projects. By default, the icon that shows in the tool box is a gear. I'm looking for a way to change that default icon to display something more meaningfull. In the 1.x framework, all you had to do was to include a bitmap file that had the same name as your class and set its Build Action to Embed Resource. ...Show All

• Windows Forms Databind to collection object

  I've created a customized collection and want to databind it to a DataGridView. After some research, I found that I need to create a bindingsource control and then bind to the specific collection object. The first problem is that I need to retrieve the collection instance for some additional method calls. How can I get the underlying collection instance back I found that the databingsource will use BindingList<T> as its internal store.

• Visual C# List<T>.Insert is very slow?

  I have been writing a class that uses the List<T> class and noticed a huge performance decrease when using the List<T>.Insert method to insert my elements in the correct position as opposed to just adding them to the end of the list. The collection is about 200000 elements big. I tested this by creating a new project that creates a new List<int> and adds 200000. After that I add another 100000 by using the List<T>.Add method. This process takes a few milliseconds on my system. If I add the 100000 elements by using the List<T>.Insert method the process takes 20 seconds +. Sorting the list after adding ...Show All

• Visual C++ Help with compiler and linker options...

  Hi, i am relatively new to C++ programming,and as i am currently using Visual C++ verion 6 at TAFE, would like to use a similar program at home. As such,i have downloaded the new Beta Express pack,and installed it,but am having trouble using the Compiler and Link functions as i am not used to using a command line compiler. I find them too confusing for a beginner,and find using a GUI based one that is similar to the visual studio one much easier to learn. My question is, how can i configure the beta express pack to compile in the IDE rather than the command line,as both the compile and link options are faded out and i cannot use them ...Show All
