方法一：

本例只讲关于响应WM_MOUSEMOVE消息的处理,其它的消息以此类推. 可以通过在对话框的WM_MOUSEMOVE消息里检查是否鼠标移进Static控件,若是,就PostMessage()给Static控件.

void CDlgDlg::OnMouseMove(UINT nFlags, CPoint point)

{

LPRECT lpRect=new RECT;

m_Static.GetWindowRect(lpRect);

ScreenToClient(lpRect);

if(point.x<lpRect->right && point.x>lpRect->left && point.y<lpRect->bottom && point.y>lpRect->top)

{

POINTS points;

::PostMessage(m_Static.m_hWnd,WM_MOUSEMOVE,NULL,(LPARAM)&points);

}

CDialog::OnMouseMove(nFlags, point);

}

方法二：

设置static控件的属性为notify static控件就可以获取消息了

void CDCSViewItem::PreSubclassWindow()

{

ModifyStyle(0,SS_NOTIFY);

CStatic::PreSubclassWindow();

}

或者直接：Create(NULL,WS_CHILD | WS_VISIBLE | SS_NOTIFY |SS_BITMAP,CRect(0,0,20,30),pParentWnd);
