At this point, you really don't know enough to be able to seek help here. I trust you are at school, and not being paid for your efforts. You should buy a book on C# and work through it. There's really no way that forum responses are going to help you much, because every answer you get is just going to raise more questions. Get a book, and work through it in a structured way. The answer is that Textbox1 is a class, and text is a property of that class. The dot means that you're accessing a property or method of a class instance.

thankyou sir....:) i am looking for a book that is simple to understand since this is my fiorst step to pgrmg
C#
http://www.amazon.com/s/ref=nb_ss_gw/104-7566679-9297512?initialSearch=1&url=search-alias%3Daps&field-keywords=C%23+24+hours[^] The first two books on this list ( both teach yourself C# in 24 hours ) should be a good starting point ( obviously buy just one ). This site is great if you get stuck on something specific, if something is not clear to you. But, you should start with the book, and use the site when something needs further explanation. That will give you the best result.

Well i believe u must be familiar with properties and functions. Every object of any class has some properties and methods. e.g class MyClass { int i; string j; void MyClass(){}//this is constructor Public void MyMethod( int x )//this is member function { return x*x; } } Now if i make an object of this class MyClass obj = new MyClass();//Notice I called the constructor. Because obj is an instance of MyClass so it must have a cope of i,j and MyMethod(int x) of its own. So what i should do to access these properties(i,j) or member function of MyClass.............Here is wat i would do. obj.i=9;//so i m using dot to access the properties of the object. obj.MyFunction(8);//Here i m calling the member functon. Now to the code u provided. obj.delegateobject = new windowsdelegates.Form2.nameofdelegate(SetText); Look at this in pieces obj is an object of any class this class must have some property delegateobject we are assigning this property(delegateobject) an object of class form2 by setting its name "Set Text". So here is the moral lesson dot is also used to access classes within a namespace. I will recomend u so hav some good book on C#.NET for beginner level. u will get the answers to most of ur questions.

well, i just run thru the question, here you declared int i, and string j.. both are private members in class MyClass. you can keep the cariables as public if you want to access it. If you want to access the private members dotnet provides another techique... "property".. in which you have more control.... like private int i; public int I { set // get // }
My small attempt...

sorry sir,is there any relationship between i&I? just like this: class Distance { float start,finish; public float Start//can i write it as start? { get{return start;} set{if(start>=0)start=value} } ... } public class MainClass { public static void Main() { Distance d=new Distance(); d.Start=5 Console.WriteLine(d.start) } } Is there a really value of Start which equals start?which word gives the Start a value?i'm sorry,my english is so bad ,I don't know whether you got my mind or not. 另：祝天天快乐。:)

heii dont worry what you wrote was correct.... the thing is simple that, private members cant access from out side the class.. thats why you got error earlier........ :) now to access that private members, we can use "Property", that is what you exactly did... usually we declare the member with small letter and Property with Capitol letter as float start; and public float Start { }

yeah,I got lots of things from you,thanks again.:)
