How do I put everything togather to work?

Hi my name is Sim.

And I would like to ask u a question.

I code in C# not so long and have basic understanding of it but I still do not get yet how to put things togather. For example, I would like to create my own id3 tag editor in C# with help of C# id3 library. That library is a dll file and now my question is how do I use it? How do I connect it to my own form and make my own bottons with functionality of that dll to be able to read and write id3 tags?

Below is another example, of a class what I do not have understanding how to connect it to my own windows form.

So I basicly need information on how to put everything to work altogather. I also want to use sourcecode found on many site with my own programms but how do I put it al togather.

Thanks a lot and I hope somebody will come with an answer.

Whether it is a part of the .NET Framework or not, you have to add a reference to a library, i.e. DLL, to your project to be able to use the types it contains. Go to the Solution Explorer, right-click your project and select Add Reference. Navigate to the library you want to use and select it. Your project now has access to all the types that that library contains.

If you have a code file rather than a compiled DLL, you can add that to your project directly by selecting Add Existing Item. This will add the class to your project as though you wrote it yourself.

Thanks a lot. I will try to figure it further out how to use that dll or class in my project.

Ok it is so that I understand what you are saying and it definetelly helps me further. Only it is due to the nature of programming so that you have to know exactly what code pieces you want to write.

And of course I can find it myself out what exactly I have to write in many of those books that I have but I also know out of my experience that I won't find exactly commands for my case and will have to brake down my head figuring out how I have to adjust existing examples for my case.

So if this wil give no further result I wil also have to do that what I just told BUT

if it is for you like english langauge C# syntax then I would like to ask you for another couple of minutes and write for me down how I would have to connect button browse with Read method that returns tag info and how I would have to code further to use that info in a text box. Als how I create an instance of a class.

I am asking pretty much I have feeling but anyway whatever you might reply if at all I hope that if that demands not too much of your time that you will write for me down what code I have to use.

It is actually the first time that I go this way in finding solution for my problem and think that it maybe way much easier if someone who speaks C# just as I do english wil find it not too difficult to write some code for me and of course other.

Thanks a lot again. I wish I could do something for you.
