這代碼的確很老，網上也沒別的了。。。。

LRESULT CbarDlg::OnNcHitTest(CPoint point){// TODO: 在此添加訊息處理常式代碼和/或調用預設值const int borderwidth = 7;CRect rect;GetClientRect(rect);ScreenToClient(&point);if (point.y < borderwidth){return HTTOP;}if (point.x < borderwidth){return HTLEFT;}if(point.y > rect.bottom - rect.top - borderwidth && point.x > rect.right - rect.left - borderwidth)return HTBOTTOMRIGHT;if (point.y > rect.bottom - rect.top - borderwidth){return HTBOTTOM;}if (point.x > rect.right - rect.left - borderwidth){return HTRIGHT;}return HTCAPTION;//return CDialog::OnNcHitTest(point);}void CbarDlg::OnNcLButtonDown(UINT nHitTest, CPoint point){// TODO: 在此添加訊息處理常式代碼和/或調用預設值// TODO: 在此添加訊息處理常式代碼和/或調用預設值if (nHitTest == HTTOP)SendMessage( WM_SYSCOMMAND, SC_SIZE | WMSZ_TOP, MAKELPARAM(point.x, point.y));else if (nHitTest == HTBOTTOM)SendMessage( WM_SYSCOMMAND, SC_SIZE | WMSZ_BOTTOM, MAKELPARAM(point.x, point.y));else if (nHitTest == HTLEFT)SendMessage( WM_SYSCOMMAND, SC_SIZE | WMSZ_LEFT, MAKELPARAM(point.x, point.y));else if (nHitTest == HTRIGHT)SendMessage( WM_SYSCOMMAND, SC_SIZE | WMSZ_RIGHT, MAKELPARAM(point.x, point.y));else if (nHitTest == HTTOPLEFT)SendMessage( WM_SYSCOMMAND, SC_SIZE | WMSZ_TOPLEFT, MAKELPARAM(point.x, point.y));else if (nHitTest == HTTOPRIGHT)SendMessage( WM_SYSCOMMAND, SC_SIZE | WMSZ_TOPRIGHT, MAKELPARAM(point.x, point.y));else if (nHitTest == HTBOTTOMLEFT)SendMessage( WM_SYSCOMMAND, SC_SIZE | WMSZ_BOTTOMLEFT, MAKELPARAM(point.x, point.y));else if (nHitTest == HTBOTTOMRIGHT)SendMessage(WM_SYSCOMMAND, SC_SIZE | WMSZ_BOTTOMRIGHT, MAKELPARAM(point.x, point.y));else if (nHitTest==HTCAPTION)SendMessage(WM_SYSCOMMAND, SC_MOVE | 4, MAKELPARAM(point.x, point.y));}

另一種
