win32_First day

今天正式開始了win32 SDK非模態化的編程，不使用資源添加來寫窗口，算是一次新的修煉吧，即使學的有些晚，但是想要更加詳細的瞭解windows各種消息機制還得從最基本的API瞭解，這對以後無論是何種編程，對MFC的封裝使用都會有更大的幫助，下面是一個非模態的窗口建立。

#include "windows.h"


HINSTANCE g_Instance;


LRESULT CALLBACK WndProc(HWND hwnd,UINT uMsg,WPARAM wapram,LPARAM lparam)
{
	switch(uMsg)
	{
	case WM_DESTROY:{

					}break;
	}

	return DefWindowProc(hwnd,uMsg,wapram,lparam);
}

	wce.cbSize				=	sizeof(wce);
	wce.style				=	CS_HREDRAW|CS_VREDRAW;
	wce.cbClsExtra			=	0;
