hit a break point in starting of the code, and step over your code one by one, and see which line is throwing exception. and let me know, so that if anything needs to be correct in it.

Any thoughts, though Math and Forms.Application class have all static methods Math class is static while Application is declared as sealed?
I can see that methods in Math class are kind of independent from each other, any other reason you know?

You only need one math-class, and having it static makes it faster by eliminating the lookup for the correct object.
Now, the "static" keyword is not there to prevent inheritance; it's there to make sure that there's only one instance of the class (a singleton). The sealed-keyword is there to prevent inheritance.
Application is a special object, containing MarshallByRefObject's - I guess that's the reason why it's not simply a static class.

How about so you can use them without declaring an instance of the class??
Seems a little obvious to me....

I'd say that's an too easy answer; only the method needs to be static to get that particular behaviour. The class doesn't need be static nor sealed. Or, in other words, item C already does what you say, without A or B being considered.
static class A
{
public static void FooBar() { }
}
sealed class B
{
public static void FooBar() { }
}
class C
{
public static void FooBar() { }
}

Yep, but then again, the question isn't real specific either.

In .NET 1.0 / 1.1, both the System.Math[^] and System.Windows.Forms.Application[^] classes were sealed with a private constructor.
When static classes were introduced in .NET 2.0, the Math class was updated to take advantage of this new construct, but it looks like the System.Windows.Forms.Application wasn't.
Looking at the source[^], the class doesn't have any instance members, and is never instantiated, so it would have made sense to change it to a static class. However, this change wouldn't make any significant difference, so it's unlikely that it will ever be changed.

Hi Friends!I want to make Vb.net application with romanies to Nepali Unicode.(When I type roman text in vb.net control(text box),there should change text into Nepali unicode). Please help me.
|
|
|
|
|
You will need to find or write a program that will translate between the two.
|
|
|
|
|
Is the translitaration of Nepali defined well enough? At least such that the Nepali version can be exactly deduced from the romanized version?
By the way, I'd suggest to process the romanized input not after each keystroke, rather after some "phrase", e.g. after spaces, commas, or on the Leave event of the textbox: Indian alphabets are syllable-centric, with the vocals being written before/after/on top/below/around the consonant (I don't know for Nepali, but that's an Indian alphabet too, isn't it?).

|
|
|
|
yes, Nepali is like indian. Please help me. I need romanized input to nepali after space.

Steps
1. Determine which Unicode character set you are using. Call this U1.
2. Determine what character set will be used in the text box. Call this L1.
3. Determine the span of characters in L1 which must be mapped to U1.
4. Find all of the characters in U1 that correspond to those found in 3.
5. Determine HOW you will store the data from U1. You CANNOT use a string.
6. Create a map of the data from 4 to 5.
7. Implement 6 storing the data as specified in 5.

I have several classes that wrap native API functions. In those classes I have declared private P/Invoke methods to carry out the class' purpose. My question is a style question from FXCop telling me that I should move those private P/Invoke methods to a NativeMethods class and thus make them available to the entire assembly. One of these messages is
Quote: CA1060 Move P/Invokes to NativeMethods class Because it is a P/Invoke method, 'OSInterface.iniWrapper.GetPrivateProfileSection(ByRef String, Byte(), Integer, ByRef String)' should be defined in a class named NativeMethods, SafeNativeMethods, or UnsafeNativeMethods.
My question is what is considered correct? I consider this to be erroneous because following this advise breaks OO design.

Whatever you want it to be.

OO-design are guidelines; you won't go to jail if you break them.
I think FxCop is giving good advice here, as the WinAPI is a giant black box we interop to. It's a single, static object. It's also not much work to have an extra class as a layer in between - you'd simply be calling a static method on a static class, instead of interop directly. The huge (!) advantage is that all your WinAPI prototypes are centralized. That makes maintenance easier; I'd rather update the signature once then in a dozen classes.
TL;DR: following OO-design would break the DRY-principle.

I can see your point, but when you consider that many of the WinAPIs are designed to work as teams and some of them you have to call twice to get the actual size of the data before you can use the call to get the data my position is that if I have a dotNet class that is the sole user of an API call it should have the P/Invoke interface internally.
Obviously if it's an API call that will be used in multiple places it should be in a global NativeMethods static class.
I just had a thought - what if I create a private NativeMethods static class for this object? I'll have to give that a try this evening. That would have dual benefits - the API calls will be obvious when reading the class source and it keeps APIs that are specific to supporting that class in the class source code and not dependent on another source file.

I just modified the class in question to have a private static class for the P/Invokes (it's in VB)
Private NotInheritable Class NativeMethods
Public Declare ...
End Class
FXCop didn't throw the CA1060 warning. Apparently it's just looking for the NativeMethods class anywhere. This satisfies both FXCop and OO Design. This private class forces the P/Invoke calls to be obvious and it allow the containing class to be understood by itself.
