VC通用控件自适应屏幕类

此为我程序中的一个类，本用于WinCE，但在桌面系统上也同样适用！

使用方法（在WM_INITDIALOG或WM_CREATE消息中加入）：

CWindowAnchor::BeginControlBound(hwnd)

手动调整控件位置：

CWindowAnchor::AddControl(hwnd,IDC_STATIC1,&WindowAnchorInfo(WAT_LEFT|WAT_TOP,2,8,4,10));
CWindowAnchor::AddControl(hwnd,IDC_STATIC1,&WindowAnchorInfo(WAT_LEFT|WAT_TOP|WAT_RIGHT,2,20,4,10));
CWindowAnchor::AddControl(hwnd,IDC_STATIC1,&WindowAnchorInfo(WAT_LEFT|WAT_TOP,2,8,40,10));

自动调整控件位置（跟据设计时资源文件中控件的大小及位置）：

CWindowAnchor::AddControl(hwnd,IDC_STATIC1,&WindowAnchorInfo(WAT_LEFT|WAT_TOP));
CWindowAnchor::AddControl(hwnd,IDC_STATIC1,&WindowAnchorInfo(WAT_LEFT|WAT_TOP|WAT_RIGHT));

响应WM_SIZE消息：

case WM_SIZE:
return HANDLE_WM_SIZE(hwndDlg,wParam,lParam,CWindowAnchor::OnSize);

响应WM_DESTROY消息：

CWindowAnchor::EndControlBound(hwnd);

代码：

#pragma once
#include <map>

#if defined (_MSC_VER)
#pragma warning(disable: 4786)
#endif

/*用于WindowAnchorInfo结构的停靠类型*/
typedef enum WindowAnchorType
{
WAT_TOP=0x0001,
WAT_LEFT=0x0002,
WAT_RIGHT=0x0004,
WAT_BOTTOM=0x0008
};

/*控件定位描述信息*/
typedef struct WindowAnchorInfo{
DWORD dwAnchor; //WAT_*
RECT rcOriginalRect; //控件的原始边距，如果为空则自动获取（仅适用于WM_INIT中）

WindowAnchorInfo(DWORD pAnchor=WAT_TOP|WAT_LEFT,LONG pLeft=0,LONG pTop=0,LONG pRight=0,LONG pBottom=0)
{
dwAnchor=pAnchor;
rcOriginalRect.left=pLeft;
rcOriginalRect.top=pTop;
rcOriginalRect.right=pRight;
rcOriginalRect.bottom=pBottom;
};
};

typedef std::map<HWND,WindowAnchorInfo> ControlHashtable;

typedef struct{
INT nWidth; //对话框宽度
INT nHeight; //对话框高度
INT nMinHeight; //对话框最小高度
ControlHashtable mapControls; //对话框所有子控件
}WindowAnchorDialog;
