Hi,

I'm unaware of any serial library, and if one existed, I would probably not use it. I use the SerialPort class directly, and adapt architecture, protocols, and code to the various needs I may have.

Do you find that the .net component is fast enough to perform at high baudrates, and handle other application processing of data from the serialPort?

Hi,

I used serial ports a lot before .NET existed, using standard Win32 functions.
From my .NET serial experience, I have no reason to claim .NET has added a lot of overhead to those functions, however I do not have proof to the contrary either.

BTW: Under high communication loads, I would not be inclined to use the DataReceived event; I'd rather use a separate thread with an outstanding Read. That way I'm in charge of how much data gets read and when it gets processed, as DataReceived lacks a clear specification.

I use the SerialPort class a lot in my work, and haven't had any issues. One of my current projects uses 921600 baud (fastest you can set in HyperTerminal) and it's been performing fine.

How to store words for a dictionary?

Hi every one, i'm trying to make a dictionary in C# in my country (Ethiopia) official language Amharic that means a dictionary that converts English to Amharic. I designed all words but it is difficult for me to store all English words that are used to be searched. Please guys help me in what format do i've to store those words?

Thank YOU SO MUCH

Maybe you can store all the words in a StringCollection and search in the collection for the desired word?

Hi,

that would have to be a Dictionary<string, List<string>> so the key can be an English word, and the value would be a list of Amharic words, as an English word may have more than one meaning and one translation.

However if you want to store metadata (such as noun/verb/...), you would have to define a class or struct Word, and then your dictionary becomes a Dictionary<Word, List<Word>>

This is less than optimal. In a large dictionary you'd have massive duplication in the List<word>'s. Probably the best option would be to do 2 dictionary<>'s and create a key/ID for the english words.

Dictionary<Word, List<int>>  TranslationDictionary;  //Amharic word, English word ID's
Dictionary<int, Word> EnglishDictionary;  //English word ID, English word

I agree.

BTW: Are you aware you inverted the translation? is there a reason for that?

That makes perfect sense.
However isn't it rather silly not to store a dictionary in a Dictionary?

How to sort Custom class which is of type array as per one of its value

miniThomas16-Oct-09 5:44

Hi,

I am having a custom class which is of type array.
one of its elements is date.
I want all elements of this class to be be sorted on basis of date.

e.g

Class Payment
{
date;
amount;
order;
}

Another calss
{
Payment[] pay=new Payment[4];
for(int i=0;i<3;i++)
{
pay[i]=new Payment();
pay[i].date="Monday";
pay[i].amount=5;
pay[i].order=abc;
}
//sort pay as per date that is populated in pay
say pay[0].date=Monday;
pay[1].date=Wednesday;
pay[2].date=Tuesday;
I want the entire row of pay to be sorted on basis of date.
}

Thanks,
Mini

Best Regards,
Mini Thomas

Populate a list with the array content.
Create a custom Comparer that compares two payment objects based on date.
Use the Sort method to sort the elements of the list.
If you need so, convert back the list to an array.

Why? don't you like public static void Sort(Array array, IComparer comparer)?

Hi Guys,

I have alerady tried with IComparable

but it doesn't return sorted array, maybe I am implementing in the wrong way.

Can you guys help me out with the exact implementation?

This payment Array is being accessed in another class say PaymentHistory and I wanna sort as per date the Payment array in PaymentHistory class.
