• DanUp Generic Horror, Inheriting types with multiple inherited constraints

  Ok, well I am having a pretty major issue getting a class with insane generics to simply compile...here's the scenario. I have an entity class, attempting to inherit from a persisted entity which on a class level accepts 3 generics, the first 2 generics have a pretty firm constraint which dictates the first type inherit from our base Entity class (which persistantentity does), and also that it has a parameterless constructor. All of that is ...Show All

• Jason K Form over Form

  How would I code the Program.cs or Form1.cs (whichever one) file so that Form 2 would appear above Form 1 as the program loads. For instance in Photoshop, the tools form appears above the main form as it loads, that's what I mean't. You can set the Owner property of form2 to be form1, then form2 will never go under form1, but it wouldn't be topmost, you can open other apps and they will go above it. I think it's Owner, there's also a P ...Show All

• efrbelgarion Should I pass an object to a class using its constructor or using a property.

  I need to instatiate a class and then assign a property with a value. One solution is to: Instatiate the class. Set a property in the instantiated class. Another solution could be: Modify the constructor of the class to accept a parameter. Use the parameter to set the property in the constructor. Any idea if one way is better than another Thanks in advance, Dave Thanks Bren ...Show All

• etrynus Typedef-equivalent in C#?

  I pass integer IDs to a variety of functions. I want to create a type for each ID so the compiler can check I am passing the right type. In C I would do this with typedefs. E.g.: typedef int personID; typedef int addressID; void DoSomething(personID p, addressID a) { ... } How can I do this in C# Creating an entire class seems like a lot of overhead. It's not enough to "guide" the programm ...Show All

I'd rather have the instantiation be null and have to test for a null: MyCla ...Show All

• Trond Elde C# analog clock runs slow on some computers

  Hi all, I have a problem with the System.Threading.Timer class that I am using for my clock. The clock runs faster on an Intel box than it does on an AMD box and it has nothing to do with the CPU speed. Has anyone come across this before Any suggestions would be much appreciated. Ok, I have found that it is not a cpu problem as I have another box with an AMD Duron XP 1000MHz(5x200) which runs at the correct speed. I have tried it on another co ...Show All
