May be you can change the sql used for binding...
for example,you could change "select id from user" into "select id as '<%=what you want%>' from user "...
I am not sure you get my meaning for my bad english.

How to determine programmatically if Framework 2.0 Full trust is set in trusted sites or not?
|
|
|
|
|
I'm not a CAS expert, but can you decorate a method with [PermissionSet(SecurityAction.Demand, Name = "FullTrust")], then call that method? If the method throws a security exception, you're not running in full trust.

there is many program that show source code in dll file. But I know you can do something to privent them to see your source code in dll file.
by the way , I cant see my comment when I create an instance of a class when I use dll file instead of source code. when I use source code( for example: class.cs) there is no problem.I can see comments. but when I use Class.dll, I cant see comment.
please guide me.
thanks

Try obfuscating the dll file.

I will use Google before asking dumb questions

In the compiler options somewhere is an option to generate an XML file, find it, and click it.
This will turn all your summaries and whatnot, into an XML file, which is read when you use your DLL in another project. Just remember to have the xml file in the same place as the dll.

As Andrei said, ofuscating prevents your codes to be decomplied (to some extent).
But remember that when you use the source of the dll (i.e. class.cs) in your project file, in fact no dll is built!! The source code is compiled and linked into your executable file!!
This is where the difference comes from.

I create my dll file in Class Library Project and use that Dll file in my asp.net web application.
I dont know anything about "ofuscating" please guide me more.

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

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.
I will use Google before asking dumb questions

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.

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

Thank you!
This looks so fine!
