Yes ! The file you downloaded isn't corrupt :) There's only one dll, a bmp and this text in the zip ! Your goal is to create a loader for that dll. But it's not that easy :) GOALS : 1/ The dll will display a MessageBox with the text "Yes, you made it work ! Cool !". Exactly that text, of course without the quotes :) 2/ You will create a DIALOGBOX (not a window :), and the dll will insert the bitmap (itworks.bmp) in it. 3/ You can't touch a single bit of my dll Then everything is up to you :) HINT: You can retreive the hwnd of an item in a dialogbox with the api GetDlgItem, then you can use it as a window hwnd :)
