此為我程序中的一個(gè)類(lèi)，本用于WinCE，但在桌面系統(tǒng)上也同樣適用！
使用方法（在WM_INITDIALOG或WM_CREATE消息中加入）：
CWindowAnchor::BeginControlBound(hwnd)
手動(dòng)調(diào)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));
自動(dòng)調(diào)整控件位置（跟據(jù)設(shè)計(jì)時(shí)資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));
響應(yīng)WM_SIZE消息：
case WM_SIZE:
return HANDLE_WM_SIZE(hwndDlg,wParam,lParam,CWindowAnchor::OnSize);
響應(yīng)WM_DESTROY消息：
CWindowAnchor::EndControlBound(hwnd);
代碼：
#pragma once
#include <map>
#if defined (_MSC_VER)
#pragma warning(disable: 4786)
#endif
