• .NET Development Catch events in javascript from .NET usercontrol works in C# but not in VB.NET

  Hello all, I've created a .NET usercontrol and embedded it in an HTML page using the implementation found here http://support.microsoft.com/default.aspx scid=kb;en-us;305624 The Control Library was coded in VB.NET 2005. I can access my properties and methods from javascript with no problem. I tried to raise events in my UserControl and catch them in the HTML with javascript but I couldn't get it to work.

• Visual Studio Express Editions Question about filtering a database.

  I would like to filter a database but cannot get exactly what I want.... The code I was trying to manipulate is this: BindingSource .Filter = " ColumnName = ItemtoFilter '" These are obviously generic names. That seems to work fine as long as you know inside the script what the user wants to filter. How do you make the " ItemtoFilter " a variable Thanks. I guess my question is how do I make the ' filter ' a variable in the following line.... BindingSource.Filter = "ColumnName = ' filter ' " ...Show All

• SQL Server Optimistic vs. pessimistic locking

  I am confused, I'll admit that outright. A lot of entries in these forums recommend optimistic locking for most cases. Well, I have a very simple case (like everyone else, I bet :-)) and it seems to me pessimistic locking is the right answer: User A loads an item on screen for maintenance. When user B wants to load the same item on screen for maintenance, he/she should be presented with a message "Item in use by someone else". That way they know they can't perform maintenance on the item (as yet). This can be achieved with pessimistic locking, by locking the row that is being loaded for maintenance and only unlocking it after an update or after another item is loaded in maintenance. The lock would be in update mode. This w ...Show All

• Visual Studio Team System ASP.net Unit tests and web application set up using a header.

  I have tried to use ASP.net unit tests against a web appilcation. The web applications URL looks somthing like, vdir.localhost .domain.com . IE is able to access the website, no problem. But the unit tests are unable to find the directory. I notice that none of the help files discuss testing against a web application that has been created using host headers. The question is, is it posible to test a web application using host headers If so, what might I be doing wrong Thanks guys!! Dan Does the URL in the UrlToTest attribute exactly match the one you see in IE If not, does changing it help Yes. When I use only the virtual directory name, it seems to find it. I will investigate this further when I get to wo ...Show All
