Google it. There are many different tools out there to help obfuscate your code.

hi.
in DateTime.Now , Now is a property. But when we set a dot after Now we can see a list of methods and properties, such as DateTime.Now.AddDay() , DateTime.Now.Date , DateTime.Now.AddMonth()
how can I do it?
thanks
mehran

If you have looked carefully at the type returned by the Now property, you might have seen that it's a DateTime object, which has properties and methods. So if you want to create a property that "has methods" you just need to create a property that returns an object that has other properties and methods.
Hope it helps.

This is so simple!
DateTime.Now is of type of class 'Date' which has itself different properties and methods!
You can create a class, and add any methods or properties in that class.
In an other class, now you may have a property of the latter class type.

I have to read the last 5 lines of several very very huge ASCII files, several times.
I want to see if it is possible to read only those last lines, instead of reading the whole junk data and getting to those 5 ending lines.
Could someone please help me, how to decrease this amount of waste of cpu time and un-wanted I/O?

You could set the position in the stream, but im not sure how accurate that would be.
The position is the current index in the huge array of bytes that is your text file, so if you knew the length of the text file...
For example, you have a text file with 5000 characters in it, you set the position too 4500, and then read the last 500 characters. That way you don't need to waste time reading the first 4500 characters.
The only problem is, how do you know where to start reading from? I'll leave that to you 
to set the position, i think its just:
myStream.Position = somewhere;
I think it's .Position anyway, it might be .Location, i'm sure you'll find it.
My current favourite word is: PIE!
Good ol' pie, it's been a while.

Yes, and there is also .Length
A) Set the Position to Length
B) Read backward until you encounter the fifth newline
C) Reverse the string

hello... i think u have to combine the data of the datagrid into a string object and then send that.... how much detail are u planning of sending.. if u have one row one column then try somethin like
string str=urDataGrid.rows[0].cells[0].value
or if u have one row multiple columns, try
string str="";
foreach(DataGridViewCells cell in urDataGridView.Rows[0].Cells)
str+= cell.Value;
or if u have multiple rows and multiple columns try
str="";
foreach(DataGridViewRows row in urDataGridView.Rows)
{
foreach(DataGridViewCells cells in row.Cells)
str+=cells.Value
str+="\n"
}
I havent tried it, but i bet id would work... u can use string.Format for formatting the string...

Hi,
You can set the active control of the form using following code :
this.ActiveControl = textBox1;
textBox1.BackColor = System.Drawing.Color.Black;
//this.ActivControl.BackColor = System.Drawing.Color.Black;
Thanks,

Hi,
Can you please elaborate your question? An example might help.

Hi!
Simply: Generate a "regular" random number in the range [0...n[ with n being the number of elements in the array of values and use it as index into your array.

the minimum value should be 0 and the maximum value should be the length of array ( minus 1). Next generate the random number b/w the range and then use myarray[randomNo], to get a randomnly selected value from the array.

Hello....i've been working in ado.net for a few months now... and am quite confused how to use the dataset object. though i know it depends on what type of project a person is upto but still i wanted to know which one is the better approach to usin the datasets...
Approach 1: fill the dataset with all tables at project load and use the dataset for all searches and things. though as sqlserver is locally placed, i update the sqlserver tables as soon as i update the data set...
Approach 2: fill dataset with only the rows that are required... ie if u need some rows according to a criteria, write a select statement, discard ur present dataset and refil it with this statement...
Please provide full information,based on performance issues of a system...
as far as i think , i believe approach1 will be better but it becomes hard to handle when u have more tables, like 60 tables... so wat should be done in this case, "A dataset for every 10 tables"? or wat...
Thanx

This depends on the type of application you want to write. It's a good practice to minimize the queries to a database when you write a web application. But still, my opinion is that it's not a good practice to read all the data from the database into a dataset. What happens when you have around 50-60 tables and each table has 50.000 or more rows. In this case you do a huge waste of memory. I think it's better practice to save into a dataset all the data needed at a certain time. This is my opinion.

lolz... cool answer... or should i say, read my whole question first and then try answering...
i have already said of making small datasets (at the end of my question)... max of 10 tables... which means max of 10 tables when data is less and it can go upto as small dataset as of one table... Also those tables should be related to each other...
now i can go on making datasets only for one row in a table and i have seen ppl doin it...and when i code, i use a single dataset for related data that is required... now i can't go on making dataset for 10 rows or 20 rows coz that won't help the cause of disconnected environment even a lil bit.
Anyways from ur answer, i feel i have a better sense than u atleast...and please don't consider answering again...
"i would think 10 times, before giving others answers that would give the impression that i am very smart..."...LOLZ
