• .NET Development Is EventHandler is heavy to use?

  I have one application and in that I have to show the waitcursor whenever any operation starts. NOw the operation starts from one class file. and it's not a form. to change the cursor we need to give the form or control reference. Now I want to use eventhandler for this. so whenever i need to change teh cursor i can raise one event and on that form application i can change the cursor. but i have read somewhere it's heavy to use eventhandler. don't use it for small purposes. Why it's heavy Can anybody tell me. Not sure why they'd think EventHandler would be expensive. Delegate calls are simply indirect calls through a list of method pointers. I tried it out, 9 seconds for one billion calls, that's 9 nanoseconds per call. ...Show All

• Visual Studio Visual Studio 2005 Addin - How to find all the controls in a webform?

  Hi everyone, I’m the coordinator of project NMVP ( http://www.codeplex.com/nmvp ). It’s a framework to develop MVP architectures. The framework is doing really well, but there’s one task I’d like to automate that is the task of creating a contract for the web form. I’ll illustrate: Imagine I have a web page like this: Username: [TextBox of Username] Password: [TextBox of Password] [Login Button] In MVP the contract for this page would be something like this: public Interface ILoginForm{   string Username;   string Password;   event EventHandler Authenticate; } So what I am trying to accomplish is: 1) When the user clicks the LoginPage : Page class in .cs file a "Refactor to NMVP Contract" item appears (done ...Show All

• Visual Studio Team System unicode with SQLCMD

  I have a bunch of DML scripts which contain Unicode characters (i.e. German Umlauts such as a,o,u). When I use the post deployment script to execute the DML using the following syntax: :r .\DML\Umlauts.sql the unicode characters are not loaded properly into the DB. The script works fine from the command prompt or using SQL Studio. Is there any way to pass along the "-u" parameter to the SQLCMD If not, is there any way to execute cmd files during the deployment process Thanks in advance for your help. Markus Gallagher I opened both the original DML file and the Build Output file with Ultra Edit and neither of them indicated that they were Unicode i.e. both displayed as DOS Format.

• Visual Studio Unable to create a new DSL project from Visual Studio

At first, after the project is unfolded I get the error message box saying “ The method or operation is not implemented” . When I press OK, I can work. I still need to run the text template manually because it probably fell before it could complete it. However, the problems are not over yet.
