Yes, what I meant to say is that I've done it, and I needed only these notes to communicate with the Win32 API, and the rest is pure simple delphi-ish coding. in Delphi 7 the DLL created is 15KB long, and then I even wrote a component to interface the application with the DLL, there are some tricks to communicate with a DLL (data interchanging), I created a messaging mechanism to do it. All in all, it's working perfectly both for key blocking and key capturing (notification).
