someone please tell me what I can do to make this compile

fazer (4)
also what would be better is explaining what i could do to diagnose how to make this compile when i get errors like this. I'm trying to superclass a window and im getting these errors

122 C:\Dev-Cpp\pocketrocket.cpp expected constructor, destructor, or type conversion before '(' token
122 C:\Dev-Cpp\pocketrocket.cpp expected `,' or `;' before '(' token

here is the code

of course its not finished, this will be my first program that I've made that's actually useful not something like iostream input word output sentence with word or hello world etc, so anything else you see that could help me improve would be greatly appreciated.

What is line 122? If it is meant to be a function prototype, it is missing the return value. If not, then explain what is supposed to be.

@Ikaron: I know the Windows API contains a function called like that. It is NOT what I am asking. I am asking the person who wrote this code about the intended purpose of line #122.

@webJose: Sorry, you weren't being very clear when you stated "If it is meant to be a function prototype, it is missing the return value." Which, if that's the case, it's not only missing a return value but also its argument types. This ambiguity in your statement is why I even bothered to point out the function's existance as a Windows function in the first place, just incase you weren't aware that it was a Windows API call.

I see. I guess it is my bad then.

What I am trying to do here is to understand the purpose of the line in order to provide an appropriate fix. I could say "remove the line", but I don't really know if that will yield the expected result or not. The intention of that line must be known before appropriate action can be taken to correct it.

Let's see if the OP comes back to clarify the intention.
Ikaron (175)
Oh, no, I totally understand your need to understand what the line is there for. I just misinterpreted your post. :)

I'm trying to superclass a window and I couldn't find any good c++ examples online, the point of line 122 is to implement the first step in accomplishing that. According to http://msdn.microsoft.com/en-us/library/windows/desktop/ms633569%28v=vs.85%29.aspx

To superclass a window class, an application first calls the GetClassInfo function to retrieve information about the base class. GetClassInfo fills a WNDCLASS structure with the values from the WNDCLASS structure of the base class. Next, the application copies its own instance handle into the hInstance member of the WNDCLASS structure and copies the name of the superclass into the lpszClassName member. If the base class has a menu, the application must provide a new menu with the same menu identifiers and copy the menu name into the lpszMenuName member. If the superclass procedure processes the WM_COMMAND message and does not pass it to the window procedure of the base class, the menu need not have corresponding identifiers. GetClassInfo does not return the lpszMenuName, lpszClassName, or hInstance member of the WNDCLASS structure.

So I tried doing that but i can't even get it to compile after adding getclassinfo, can't figure out what im doing wrong.
