Simple Listview Filemanager

Hi,
I'm working on a project which requires files to be copied from one directory to another (only 2 key directories), and then to edit an ini file to reflect the change. The way I think would be the best is to make a simple dialog app with two listviews. The first displays the contents of the first directory and the other displays the content of the second directory. I then need to allow a user of the program to drag a list view item (file) from one list view to the other. When this is done i want the file to be copied and the ini file to be updated. I understand how to update the ini file. What i need to know how to make 2 listviews display the contents of a directory and allow files to be dragged across. If that operation also called a function, it would be great because i could put the ini file code in it.

I looked at MSDN but i can't find anything very on topic. Plus, i've been having trouble downloading MSDN examples. Can someone show me the key things to know about this, or point me in the direction of a sample application.

will the drag and drop project let me drag and drop from one list view to another, as opposed to from explorer to a list view?

I'm not sure if that project will drag and drop between between controls, but the following project will drag and drop between controls.

Another project that will drag and drop between derived windows:

sorry for the delay. The DandD example is perfect!! Is there a way to make it work with a CListCtrl instead of a CListBox? I tried just deriving from ListCtrl but i got this error:

error C2248: 'messageMap' : cannot access protected member declared in class 'CListCtrl'
        c:\program files\microsoft visual studio\vc98\mfc\include\afxcmn.h(294) : see declaration of 'messageMap'

Also, is it possible to adjust it so that when i drag and drop, it copies the entry instead of moving it? I looked over the guidelines on the webpage but couldn't find any instruction as to doing this.

nevermind on the copy insted of move part. I read the directions backwards. I just removed the override of the CompleteMove function and it works.

This is part of the standard Windows behavior, which most windows users would expect.
If the user wants to copy it, the standard method is to hold the shift key, while dragging.
This method should work in your application as well.

I'm sorry, but I haven't done done MFC code in a while.
You might want to try asking in the MFC topic area:

ok, i'll do that. i'm looking over the example right now, just making sure i didn't miss anything. i'll close this Q out in a few mins. I am just making copy standard because this program will be copying critical files. These files must absolutly not be moved. I just don't want a possibility of error.
