Google: Data structure and Algorithms in C#. It's not hard. I know there are at least 3 sites that will provide you all the code. But the first step for you is to try and do it yourself. We dont spoonfeed. If you have a specific problem, we will help.

How could they not be present ? Under what bizarre circumstance do you expect only half the .NET library to be installed ?

Please read this if you don't understand the answer I've given you. If you're still stuck, ask me for more information.

cheked list box control

there is a table in database, having feild StationName & pk as stationID.

Now i am adding the StationName in chekedlistBox control and also using stationID in Tag property for each item i add.

after this what i want to do if a user check 1 or more item from list, then all those items deleted/updated(whatever function i want to perform) ona button click.

I am doing this as:

a) On form load event populating the CheckedListBox control.
b) On Button click event performing my action.

IEnumerator myEnum = chkList.CheckedIndices.GetEnumerator();
string SQL;

while(myEnum.MoveNext() != false)
{
  SQL = "Update A Set [xyz] = 1 where [stationID] =" chkList.Tag.Tostring();//sample query 
  ExecuteSQL(SQL);// method i m calling to update
}

the tag property is not giving the corresponding stationID for stationName.

What is wrong?

Also how to use foreach loop for chekedListBox items?

You need a + to concatenate strings.

i miss type here?
that i know........??

problem is TAG property not giving the corresponding StationID for StationName which user selected

leppie3-Jul-08 2:20

Yes, that will happen, because you are referring to the same checklist object all the time.

You need to cast the current enumerated object to what you put in there, and then get the value.

How to protect my c# code from decompiling

3-Jul-08 3:57

That depends on the data type you passed into it.

I am willing a create C# windows application and wanted to distribute it through internet.But I came to know the the .net assemblies can be decompiled.There are so many Obfuscaters avilable but i don't have money to buy that. Can anybody suggest anything other than Obfuscaters.

I believe VS 2008 comes with a obfuscater community edition which will be free.

All C# applications should call Application.Quit(); in the beginning to avoid any .NET problems.- Unclyclopedia

can i use it for 2.0 applications and does Obfuscaters protect my code 100 %.

No. But by asking this question, you likely will not need one. If you have some serious IP to hide, write it in C/C++.

No . I don't want anybody to see my code.It is not a case of IP or something like that

If its something ground breaking, get a patent. You wont be able to stop someone 100% from reading your code.

Why are you worried about people seeing your code anyways?

Don't say some bullshit if you don't know the answer.
Every company is concerned about their source code.
I am creating a product by after a lot of hardwork.
Someone simply decompiling my code a creating a new version of it.
what is the meaning in that.

You do know that IP stands for Intellectual Property, don you? That would be the only thing that you would really want to protect in the first place.
