- Using a #define statement Under the assumption that you create your own 'Color' class... The principle would be that you expose the 'Standard' instances as a public static property, eg: Code Snippet class Color { public static Color Red = new Color(255, 0, 0); public static Color Green = new Color(0, 255, 0); private int r; private int g; private int b; public Color(int r, int g, int b) { this.r = r; this.g = g; this.b = b; } public int R { get { return this.r; } } public int G { get { return this.g; } } public int B { get { return this.b; } } } Tag: Clearing class instance

- Factory pattern problem My goal is to do the following: I have several data types that share several common properties. I have placed the common properties into an interface, and I'm consuming this interface by each of the data types. The properties of each data type will be persisted to a database, including those properties that are unique to the property (and hence, the source of my problem above). My goal is to build a process (a factory) that can as effeciently as possible allow for new data types to come along and utilize this process, while having as minimal impact on the factory process as possible. In addition, I want to send each of these transactions along on a background thread. All of this is happening on my server-side middle tier. Kirk Tag: Clearing class instance

- Best storage practices I agree. I'd use either an access database (which has a nice scalability advantage if you decide to upgrade your program later on) or XML (which has the advantage of portability, and can still allow for a decent upgrade to a database if you do it right). I'd argue that nowadays there is little reason to write out plain text files. -mwalts Tag: Clearing class instance

- Algorithm for getting a value from a dynamic logarithmic scale? It seems like there are a few different things going on with this function you are describing. The first issue is a way to continuously go between a log function and an exponential function. (like the "base" parameter you describe, which doesn't really have anything to do with the base of the logarithm, if I understand correctly). I can't think of a function off of the top of my head that does this besides just interpolating between the two functions. So, I just spent an hour trying to figure this problem out...I came up with a solution, but you're not going to like it much, at least I don't. So my simplified problem is as follows: Given: x (unscaled value), q (curvature factor), b (logarithm base) Find f(x, q, b) where q is the variable such that q = -1 gives log_b(x) (the base b logarithm) -1 < q < 0 gives the function which consists of points that are the weighted average along a line with slope -1 between the logarithm function and the line (a diagonal type of weighted average...I know this isn't very clear) q = 0 gives x 0 < q < 1 gives a similar weighted average between the line and the exponential function q = 1 gives b^x I drew some pictures and did some algebra, and unfortunately, got to something that is not closed form. I used Maple to figure out what function it is. For q < 0: (q in all of these equations is actually |q|, i.e., -q) f(x, q, b) = a*(1-q) + log_b(a)*(1+q) where a = e^((b*(1-q)-2*x*ln(b))/(q-1)); where b = LambertW(ln(b)*(1+q)*b^(-2*x/(q-1))/(q-1)); LambertW is the Lambert W-Function , which (according to the Wolfram site I linked to) can be approximated well as LambertW(z) = L_1 - L_2 + (L_2)/(L_1) + (L_2(-2+L_2))/(2L_1^2) + (L_2(6-9L_2+2L_2^2))/(6L_1^3) + (L_2(-12+36L_2-22L_2^2+3L_2^3))/(12L_1^4) + (L_2(60-300L_2+350L_2^2-125L_2^3+12L_2^4))/(60L_1^5) where L_1 = ln(z) and L_2 = ln(ln(z)). I didn't finish it for q > 0. Okay, this is pretty complicated for what you're trying to do...sorry about that. I was hoping it would be a nice solution. Just to make sure you're still interested in this problem before I do any more work, I'll wait for you to reply before I do the solution for q > 0 and give you the code. (This is fun for me, so don't worry about that). Also, if I've misunderstood something in your problem, let me know. To clarify, what I've been working on so far is a function that can blend nicely between a logarithmic function and a linear function. Tag: Clearing class instance

- How to invoke a method defined by a derived class from the base class reference?

- Modifying an exception by ref? You can make your own exception like this. class MyException: Exception { } Then there are 2 ways of throwing a exception: throw ex; //throwing the original exception or: MyException ex2 = new MyException("your text"); ex2.InnerException = ex; throw ex2; Now you can test in a catch block which exception was thrown: try{} catch(MyException ex) { do something} catch(Exception ex) { do something else} Tag: Clearing class instance

- Importing virtual functions from a Dll I'm using VS2005 and I'm trying to import a bunch of unmanaged classes from a dll. The DllImport attribute, requires you to declare you methods as static extern, however that does not mix well with virtual functions. I'm getting the following error: "Error 1 A static member CreateSignatureForSinglePackage(out byte[], int, out byte[])' cannot be marked as override, virtual, or abstract" With pure virtual functions, instead of importing them from the Dll I declared them locally with an empty body, however if I use that same approach with "normal" virtual functions, I'll loose the code in the base version. Any ideas Tag: Clearing class instance

- Which One is faster???? The form: int a = 0; if( 1 == a ) .... is a c-ism, and a relatively useful one. C will allow you to do the following: int a = 0; if( a = 1 ) // note, we're not using == here... ..... This will happily set a to 1, and evaluate to 1, which in C terms is true. This will make the conditional code run, which is probably *not* what the programmer intended. OTOH, if you use the 'value == variable' form, you'd get: if( 1 = a ) ..... which would attempt to assign the value of a to the constant 1, which will cause a compilation error, which can help prevent a lot of debugging. This isn't necessary in C#, as C# won't allow the first form to work. C# requires a boolean value in a conditional, so when a = 1 evaluates to '1', it generates a compiler error. You can still do assignment as a conditional with something along the lines of: if( ( a = 1 ) == 1 ) .... The given example here is pretty silly, but if assigning a to the return value of a function, it's a pretty useful construct. For instance, if( ( a = foo() ) == someval ) may be useful in some situations. However, C# *will* allow the following to work: bool b = false; if( b = true ) ..... which is, again, probably not what the programmer wanted. This works because the general form of 'var = val' will evaluate to the type of var, which in this case is bool, and so C# says "Hey, I've got a bool in my conditional, I'm good to go!" Fortunately, the compiler *is* smart enough to realize that this is probably not what you wanted, and at least generate a warning for you. Using the form: if( b ) .... prevents this error, and is probably preferred for that reason. Tag: Clearing class instance

Please check the following code,
I tried to distroy like this = null. But it throws error like this is readonly. How can I do this. I want to restrict the class instances to 5. If count goes more than 5, the object has to be destroyed. Anyway to do so

public MyClass()

throw new Exception("Can't create more than five objects"); else
Count++;
}
}

Hi Manju,
Thanks but, it's foolishness to do so. Because I can catch that exception where I am invoking the class and I can continue using the object. Throwing an exception won't make the class instance not usable.

Re: Clearing class instance

Hi,
You can do this like this, by creating a factory method and having private constructor.
LIke this
class
MyClass{
public static int Count = 0;
private MyClass()
{
Count++;
}
public static MyClass Factory()
{
if (Count==5)
return null;
else
return new MyClass();
}
}
And use this like this
MyClass obj = MyClass.Factory();
I hope this solve your problem.

Manju Sandhu

No you can't continue using the object, because you will not have a reference to it if the constructor throws, even if you cantch the exception.
