• Game Technologies: DirectX, XNA, XACT, etc. Question regarding best way to design my engine

  Currently I have a system (quite basic) with a character moved by a 360 pad, a level with about 10 objects in and I'm wondering the best way to handle my game logic. My Question is really this - I like the way that in Xna the Update and the Draw are seperated - however to use them as I would *assume* they are intended, draw *should* only really draw things, and Update should be where the game logic is updated: To use what i think Xna wants me to do is //Pseudo code void Update() { foreach (LevelObject lo in LevelObjects) { CheckForCollisionWithMainCharacter(lo) } } void Draw() { foreach (LevelObject lo in LevelObjects) { Draw(lo); } } Which seems slightly innefficient to repeat the same loop twic ...Show All

• Visual C# many radiobuttons in deifferent groups without GroupBox

  I have many groups of radiobuttons in my win form. but I dont want to add Groupbox for every each group of rb. can I set some property in order to group some rb together or using groupBox is the only way to do it thanks in advance for your help, Edward Yuu can use Panel and put a set of radio button in it and use anoother panels and do the same with Radii buttons. You'll get your desired result and Panels will not be visible seprately at run time. Basically to group some Radio buttons you need some container to hold them, Container's Example: Form, Panel, TabControl. In Simple words, a Control which can hold other controls!

• Windows Forms Problem with List<T> and TypeConverter

  Hi, I am having a bit of difficulty with TypeConverters and Generic Lists and I was hoping that I could get a bit of advice. I have a type converter that is used to create the constructor code for my component. (It is an XNA a Game Component, but I don't think that that has anything to do with the problem because it appears on a Winform) inside another component. For instance I have the following: public class A{ private string s; public string SProp { get { s = value;} set { return s;} } public A() { s = "" ; } public A( string inS) { s = inS; } } By itself, when class A is an object on a form (or in my XNA Component) the TypeConverter code works fine, the property grid on t ...Show All

• Visual Studio 2008 (Pre-release) Tooltip on a GridViewColumn?

  I want to be able to apply a generic template to a gridviewcolumn, so that a tooltip appears when I mouse-over each cell. The way I'm doing it now is by making a datatemplate for EACH column, to be able to bind to the right property. Example: < DataTemplate x:Key = " PostalCodeStyle " > < TextBlock ToolTip = " {Binding Path=PostalCode} " VerticalAlignment = " Center " Margin = " 2 " Padding = " 2 " Text = " {Binding Path=PostalCode} " /> </ DataTemplate > < DataTemplate x:Key = " CityStyle " > < TextBlock ToolTip = " {Binding Path=City} " VerticalAlignment = " Center " Margin = " 2 " ...Show All

• Smart Device Development Another VS2005 and Smartphone Question

  I posted yesterday about some links or assistance with navigating the treeview control in VS 2005 for Smartphones. Well, I pretty much solved that problem, but that created another issue. I have two modules that are used to dynamically build the appearance of a form before it gets displayed. The form exists in the project and when control is passed to one of the modules that references this form, at the point that the form is referenced in the module, I get an error saying the form does not exist. Initially, I used the With statement to reference the form objects but even if I comment the With/End With statements and reference the form objects explicitly, I still get this error. I tried showing the form before any reference is made t ...Show All

• SQL Server package path referenced an object that cannot be found

  I am running Final Relase of 2005 version 9.00.1399.  I built an Integration Services package saved it closed up, came in the next day opened the project and I get 46 Warnings and the message on all of them is similar: "Warning loading Package.dtsx: The package path referenced an object that cannot be found: "\Package\Truncate Temp Table.Properties[Connection]". This occurs when an attempt is made to resolve a package path to an object that cannot be found."
