win32的一个售票程序，收获有非常的多

先秀一下我的收获吧！

1、在创建非模态对话框的时，需要用到createdialog函数，第二个参数需要注意是填写对话框的资源标识符（id），之后需要调用showwindow来显示对话框；或者不这么做也行，就是在对话框属性visiable设置为true；

2、hdc变量最好在函数内初始化，别将它直接传入函数；

3、WM_SIZE的wParam参数很有用；

4、关于movewindow

MoveWindow sends the WM_WINDOWPOSCHANGING, WM_WINDOWPOSCHANGED, WM_MOVE, WM_SIZE, and WM_NCCALCSIZE messages to the window.

5、WM_WINDOWPOSCHANGED消息的lParam参数只向一个WINDOWPOS结构体的指针，所以我们可以利用这个指针时刻调整我们的窗口位置或者大小，很有用，

wndpos = (LPWINDOWPOS)lParam;

6、获取对话框内的控件id也因getdlgitem（）变的很方便，还有一个getdlgitemid（）也很方便；

7、WM_CTLCOLORDLG消息不详细解释啦，直接看msdn：

The WM_CTLCOLORDLG message is sent to a dialog box before the system draws the dialog box. By responding to this message, the dialog box can set its text and background colors using the specified display device context handle.

直接上代码了，功能还不是很完善的，算法也算简单，作为一个win32的初学者，也有那么一点点的成就感。
