I am a newbie in win32 API and I'm trying to write an app that will calculate the md5sum of a file selected through the menu or dragged and dropped in the window. I want the window to have 3 columns so that it can display the filename, path and md5sum respectively. Can someone please give me a sample code as to how to make my window look like this?
Also can someone please add the code to create the window as listbox while the menu and drag-drop options are retained?

ofn.lpstrFile = dest;
ofn.nMaxFile = MAX_PATH;
ofn.Flags = OFN_EXPLORER | OFN_FILEMUSTEXIST | OFN_HIDEREADONLY;
ofn.lpstrDefExt = L"txt";
