C++ DLL Sample

I need a simple C++ Win32 DLL written and a sample .exe that loads the DLL and unloads it. This is for test purposes and has nothing but a simple function. The DLL once loaded should create a window and do a recursive file listing on C:\ into a textbox. If any file with .txt is found, echo the first line of the file to the textbox. Part two is very much the same except this is an OCX / Com Object. The com object implements HelloWorld(const wchar_t *lpszFilename). This will simply return the contents of the file. The sample exe just loads the dll and then loads the ocx to test that it works. This is really very simple, possibly only a few hours of work to get done right. It must all be done with Win32 (no mfc or atl)
