use OPENFILENAME struct
Code:

    OPENFILENAME ofn;
    char szFileName[MAX_PATH] = "";

    ZeroMemory(&ofn, sizeof(ofn));

    ofn.lStructSize = sizeof(ofn); // SEE NOTE BELOW
    ofn.hwndOwner = hwnd;
    ofn.lpstrFilter = "Text Files (*.txt)\0*.txt\0All Files (*.*)\0*.*\0";
    ofn.lpstrFile = szFileName;
    ofn.nMaxFile = MAX_PATH;
    ofn.Flags = OFN_EXPLORER | OFN_FILEMUSTEXIST | OFN_HIDEREADONLY;
    ofn.lpstrDefExt = "txt";

    if(GetOpenFileName(&ofn))
    {
        // Do something usefull with the filename stored in szFileName
    }

that's manage C++ (aka c++.net) i don't really like that language since it's not a pure C++
but i guess there should be OpenFileDialog control to drag
other than that can't help u much since i don't know that type of c++

I'm pretty sure he wants to run the file. Check out ShellExecute()

Don't use managed C++, there is no support for it any more, switch to C#.
