求高手指点

好几个问题：
一：
int WINAPI WinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPSTR lpCmdLine,
int nCmdShow);
不该有分号。

二：
LRESULT CALLBACK WinSunProc(
HWND hwnd, // handle to window
UINT uMsg, // message identifier
WPARAM wParam, // first message parameter
LPARAM lParam // second message parameter
);
只有声明，没有实现。

三：
如果你的程序建的是控制台而非win32程序，请如下修改设置（编译环境为VC6）：
1.进入project->setting->c/c++, 在category中选择preprocessor,在processor definitions中删除_CONSOLE, 添加_WINDOWS
2.进入project->setting->Link, 在Project options中将 /subsystem:console改为/subsystem:windows.
3.保存设置，Rebuild All.

int winapi winmain(hinstance hinstance,hinstance hprevinst,lpstr lpszcmdline,int nshowcmd); 后面多个分号呀，去掉就好了
