• Windows Forms private static methods vs private non-static methods?

  Could someone please tell the difference between private static methods and private non-static methods. I know that a static method is created only once per class rather than in every object based on that class, and we can access a public static class member without creating an instance of the class. However, I am not quite sure when we should use private static methods. Thanks. You can use a static method when its outcome doesn't depend on the values of the class instance. To use the worn MSFT example, the Dinosaur class can represent various species of dinosaurs. The EatMammal() method could be static, the EatTreeLeaves() couldn't. The rulez change when you change the hierarchy. If your base class is ...Show All

• Windows Forms DataBound DateTimePicker/ComboBox Events

  Events on Databound controls that have their Visible Property set to false at DesignTime do not fire events. I was told this was part of their design. I accept that fact. But controls that have Visible set to true at design time and then Visible gets set to false at runtime, will fire events even though Visible is false. Question 1: Why does having Visible = false at Runtime and Design time behave differently Question 2: What internal happenings occur that make the control start firing events and can I trigger this internal change (i.e Can I force a Control with Visible = false at Design fire its events or visa versa can I make a control with Visible = false at runtime not fire events) How to Repeat: I attached a simple ...Show All

• Visual Basic Generating executables in visual basic 2005 express edition?!

  I and a friend have been working on a project in visual basic 2005 express edition now that its complete we have a problem... we cant find how to generate an executable file we DO NOT want to have an installer we want a simple download and use no installation and .application isnot acceptable. If you dont want to use an installer or anything - you have to ensure that all the requirements and the .NET framework are in place for an application to work. Using ClickOnce to build and deploy an application is really extremely simple and results in a professional installer which will make sure that the requirements are on the client machine for your application to work.

• Game Technologies: DirectX, XNA, XACT, etc. Tutorials Thread

  If it's not too much trouble, could this topic be stickied I am just wondering if we could have a main thread that carries links to all the tutorials. In other words, someone makes a thread with a new tutorial, and then, they post the link to it here with a description of the tutorial. That way, others don't have to search through a whole forum for just one topic. Just an idea to make it easier on everyone.   On a side note, I plan on linking this thread to another thread titled: First XNA Program Development Team (FXPDT). Take a look at it. Thanks for your time. Also, I've added some tutorials for you all for now.   P.S. Since the tutorials are publicly viewed and linked to, I don't think you need permission to ...Show All

• Visual Studio Team System Save default constraints in a separate file

  Hi I have just installed the VS TS DB Pro and it seems really nice to me, however I would like to know if its possible (or will be in comming releases) to save the default constraints in a different file from the table deffinition. Currently each time we have a new release from our software for upgrading the databases of previous versions we drop all objects except from the tables (to save the user's data), and then we create all the objects again: constraints, indexes, stores procedures, etc. It will be very useful to us to have the constraints in a different file, so that when we upgrade a database we use all the scripts except for the table defintions.

  Hi there, Every time I try to use Help --> Search I get the error below: "Configuration system failed to initialize" I have tried to repair the VS 2005 and MSDN installation but the same error occurs all the time and I am not able to do any search for code samples anymore.

• Visual Studio Team System Showing project portal in internal web browser

  Does anyone know if there's a way to modify the "Show Project Portal..." function (from right-click menu in the Team Explorer side-bar), so that it displays the WSS site in the internal browser instead of opening IE Hi, Unfortunately this is hard-coded behavior and cannot be changed externally. I'm guessing that the reasoning behind this is that it would be easier to see the doc's side-by-side with VS and the work item form that way, but I don't know for sure. -Dennis ...Show All

• Visual Studio 2008 (Pre-release) Any chance of expression composability in Orcas?

  i.e. Expression<Func<string, bool>> linq = s => s.Contains ("LINQ"); Expression<Func<string, bool>> oracs = s => s.Contains ("ORCAS"); Expression<Func<string, bool>> either = s => linq (s) || orcas (s); This has been mentioned before, but I'd like to reiterate it since it's not in the Jan CTP :) This feature is quite important. Without it, LINQ to SQL queries are only partly composable. Thanks Joe Hi Joe, I'm not sure if I posted this to any of the previous threads that you participated in. This can be (partially) solved using other existing C# 3.0 features, but I'd like to see direct support for this in future version of C# 3 as well. U ...Show All

  I want to truncate a table (remove all of its data) using an "Execute SQL task" and then populate that table using a Data Flow task. In case of failure, I want to "rollback" the table to its state prior to its truncation.

• SharePoint Products and Technologies Issues With Delay Activity

  Has anybody had any success using the Delay activity within Visual Studio authored workflows Whenever I include a Delay activity in my workflows the workflow goes to sleep and never wakes up. If I listen for a Delay activity along with other events inside a Listen activity, I find that the other events (for example, OnTaskChanged) cause the workflow to be rehydrated as expected but the Delay activity does not. It doesn't seem to make any difference what the TimeoutDuration is set to or whether it's set statically in the designer or dynamically inside an InitiializeTimeoutDuration method. Does anyone have some sample code with Delay activities working correctly This is a bug in workflow runtime. Microsof ...Show All
