• Xp3ll3d A question of OO structure...

  Hello All, I'll do my best to explain what I'm trying to accomplish and look forward to any and all suggestions you have for the "proper" way to do this (realizing there is no 100% correct way, but some methods are more optimal than others). I apologize in advance for my n00bness. For this example, I'll use football (american) players. I want my Player class to have a List<Stat> collection of my Stat class. Each Stat, which is an indicator of how well a player plays a particular position, should have a base value but be able to return a "true" value which is a calculation of the base value plus a percentage of one or more other stats. For example: a Player's Halfback stat might be base value plus 50% of the Fullba ...Show All

• Electronic75 Operator that adds two Points

  I think I would have to use the following code: public static Point operator + (Point point1, Point point2) {     return new Point(point1.X + point2.X, point1.Y + point 2.Y); } But I don't know why it doesn't go Ok I think the problem is that I wasn't defining the operator in the Point class. Thanks, What probelm do you get The following works fine - I copied & pasted your method into this class: class Point { private int x; private int y; public int X { get { return x; } set { x = value ; } } public int Y { get { return y; } set { y = value ; } } public Point( int x, int y) { this .X ...Show All

• Phil026 How to show all TODO items?

  When I open the "Task List -> Comments" not all TODO's from the project are shown. It seems that the IDE does only scan the open files. What do I have to do Hi, MartinZ. You are correct. Unfortunately, this is a limitation in Visual Studio 2005 C# projects . For C# projects the Task List will only display comments for open files. From "How to: Create Task List Comments": "With Visual Basic projects, the Task List displays all of the comments in the project. With Visual C# and Visual J# projects, the Task List displays only the comments that are found in the files currently opened for edit. With Visual C++ projects, the Task List displays only the comments that are found in the file currently ...Show All

• torvaldson Inexplicable behavior following removal/renaming of linked resources

  I am a beginning C# developer, and my project had been coming along nicely until the following: (1)    Before problems occured, I had a program with perfectly functional MenuStrip and ToolStrip controls (the Microsoft standards), many of whose items had image properties set to linked resources.

• Eljdee1 How to Get One Millisecond Timer?

  Currently I am working on a Signal Graph control. The control will draw the signal state (ON or OFF) for selected device or IO point. I need a Timer that tick every 1 millisecond to scan the signal state because signal state change too fast (ON and OFF). I had tried all the 3 timers provided in .NET Framework, which are System.Timers , System.Threading.Timer and System.Windows.Form.Timer . However, I failed to get a timer that can tick in 1 millisecond. All of them had a delay between first tick and second tick: System.Timers : delay about 15ms System.Threading.Timer : delay about 15ms System.Windows.Form.Timer : delay about 60ms The delay cause me missed some of the signal state.
