Error in tutorial?

I've been looking at the tutorials at http://www.32bits.co.uk/ and i tried to compile the first program and i get errors:

41 c:\windows\desktop\window.cpp
ANSI C++ forbids implicit conversion from `void *' in argument passing

63 c:\windows\desktop\window.cpp
ANSI C++ forbids implicit conversion from `void *' in argument passing

The actual lines of code are here:

41:

Code:

---

HWMD hWnd = CreateWindow(strAppname, strAppname, WS_OVERLAPPEDWINDOW, 100, 100, 640, 480, NULL, NULL, wc.hInstance, NULL );

---

63:

Code:

---

UnregisterClass( strAppname, wc.hInstance );

---

I think it has to do with strAppname, I get what the error is, but I don't know how to fix it. Any Help?

It's not an error in the tutorial. You need to read it before you try to compile it. He clearly points out that none of the code is complete and ready to compile until tutorial 4.

This is the note from tutorial #1 (in bold red on his site)

Important! Don't expect to be able to compile or use ANY of the sample code until chapter 4. To save throwing far too much information at one time at you, the code is broken down into un-usable sections until chapter 4, which brings it all together. The download for chapter 4 is a complete MS Visual C++ 6 workspace in a .zip, containing the final skeleton code which will compile correctly.
