Hello everyone!

I am facing trouble in doing containership in c++/cli. I have got two classes. One is a directory class with a data member "System::string^ path" and the other class is "file" with the data member "System::String ^ name".

Now the idea is: directory contains a file(composition) and also, a directory may not have any file (dynamism). I am able to do create an inheritance relation, but obviously it doesn't make any sense. So I need a little help on how to create the above described relation between the two classes.

My second problem is: I am doing a project that indexes all the contents of a specified path and then offers different searching methods. One of these methods is, "search by word". I will be limiting it to some 20 predefined words. Now I have to open a file(say a doc file) in the console and then do the string comparision. But I don't have any idea how to open the file in the console and also, how to do the comparison (I mean how a doc file will be treated as a file which is created by using console and how the words will be converted in System::String).

Hope I will get some help from you people:). One request: Kindly don't consider third party softwares as the solutions as I can't use them(BOOST libraries and Dirent.h...)

In addition to Richard's Answer: there is no such thing as "open file in console". You just open a file, use System::IO::StreamReader as you need just to read it.

If you need content comparison at the level of Microsoft Word document, this is a separate issue. Start from here: http://msdn.microsoft.com/en-us/library/z63ctsh2.aspx[^] or here: http://msdn.microsoft.com/en-us/library/bb726434(v=office.12).aspx[^].

1. There is not any relationship between your two classes that I can see, although a Directory object may contain File objects.

2. You open a file by one of the file or stream methods. If by a doc file you mean a MSWord document then you will need to refer to the Interop assemblies[^] on MSDN.

Also I don't see the relevance of your references to "the console" in your second question.
