• Game Technologies: DirectX, XNA, XACT, etc. cloud of dust like in battlefield 2 : mc

  does anybody know how the developers from battlefield 2 : modern combat did the cloud of dust effects did you know what i mean I played BF2 on a ps2 a good number of months ago so I'll admit that my memory is a bit foggy (yes, that was a pun). But if I'm not mistaken, the effect you're talking about is the smoke grenades right When I played it, I seem to remember them just being a particle system with big sprites. With the alpha blending, it did a good job of partially obscuring the other players in the smoke ... a sniper with a straight shot could still pick them off, but it wasn't easy. Is that what you were referring to ...Show All

• Visual Studio Express Editions Adding more than one record

• Windows Forms What is the difference between Click and MouseClick events?

  When trying some codes on a treeview I have found that when selecting a node by mouse events occur in such order: 1 - MouseDown 2 - Click 3 - MouseClick 4 - MouseUp 5 - AfterSelect When I look at the definitions of the events in the Event Borwser, the default explanations are: Click: Occurs when the component is clicked MouseClick: Occurs when the control is clicked by the mouse. Since there is no other opportunity than clicking by a mouse, what is the difference between Click and MouseClick events according to the compiler (Not that the " one occurs for component but the other occurs for control " answer please) Regards. MouseClick will fire when you click with the mouse. Click will fire when yo ...Show All

• Visual C# Whats the equivalent of __LINE__ and __FILE__ in C#

  Whats the equivalent of __LINE__ and __FILE__ in C# I thought this hot-button issue would have been answered by now. But no one seems to have a good answer for this. I would love to see a solution which presents no runtime overhead. What about C# 3.0 does it address this issue They are instructions to the compiler to replace these "constants" with de line number and filename at the place where the compiler finds these constants. Sort of a compiler directive. Usefull for debugging. Personaly I don't think they have much use in c#. ...Show All

• Visual Studio Express Editions How to create a event handler?

  If I have an option.For example: Reading.Stopping() -> C# tells me that this is a event handler. How I can use it like Mouse_Over I hope you understand me... place the eventhandler/delegate after the class declaration: public partial class someClass { //event/delegate goes here //then perhaps in some initialization method or if its on a form, on the formload create the event: public void DoSomeInitialization() { this.OnEventSomeEvent += new someDelegate(someClass_OnEventSomeEvent); } } ...Show All

• SQL Server ORDER BY efficiency

  Hi, I'm using a table with about 5 million records, i'm preforming a select query onthe table. I retrieve from that query about 2-4 million records when i'm not sorting the data the query return very fast. If I'm sorting the data (ORDER BY timestamp - when timestamp is a BIG_INT with an index) the query takes a long time to return about 30 seconds. I tryed to do the same thing with access DB and i get better results: the query with ORDER BY takes about 1 second. I dont think it's possible that access DB have better performance then SQL server, does any one have any idea what can be me problem thanks ishay. What's the definition of the index on the timestamp column Is it the clustered index ...Show All

• Visual Basic VB .NET app - control box doesn't close app.

  I have created a VB .net MDI application, all is fine EXCEPT the control box cannot close the application. (i.e. clicking on the 'x' at the top right of the window does nothing). I have got a menu item called file | exit that calls Application.close. but this is the only way I can close the application. The 'x' top right used to work. Why has it stopped Do I need to add a handler for it - but where is the event for it thanks in advance Martin Unless of course someone knows how to put code to intercept the "CloseBox Click" (or whatever it's called) - then I can code around the whole thing. cheers Martin ...Show All

• SQL Server SQL Server 2005 SP2 CTP1

  The word is that a public download of SQL Server 2005 SP2 CTP1 is available. Does anyone know whether this is true - and if so, where can it be downloaded The reason for my interest in this service pack is that significant changes around the behavior of subcube queries in AS should have been made, and I would very much like to test this. Subcube queries present a significant challenge when combined with certain types of calculated members.
