请问msg结构中的wparam中在on—ctlcolor中包含有发送者的ID吗？

如题
新手，希望各位高手不吝赐教

我想知道wparam中一般包含什么信息，有没有发送控件的id信息？？

WM_CTLCOLOR
The WM_CTLCOLOR message is used in 16-bit versions of Windows to change the color scheme of list boxes, the list boxes of combo boxes, message boxes, button controls, edit controls, static controls, and dialog boxes.

Note For information related to this message and 32-bit versions of Windows, see Remarks.


SendMessage(
(HWND) hwnd,
WM_CTLCOLOR ,

);

HBRUSH zdjc::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);

if(nCtlColor==CTLCOLOR_STATIC)
{
const MSG *msg=GetCurrentMessage();
if(int(HIWORD(msg->lParam))==IDC_EDIT1)
pDC->SetBkColor(RGB(255,255,0));
}
// TODO: Change any attributes of the DC here

// TODO: Return a different brush if the default is not desired
return hbr;
}

我想用上述方法让窗体内的指定控件改变背景色，为什么没有反应？？

hbr给各其他值

[yxz_lp]

HBRUSH   zdjc::OnCtlColor(CDC*   pDC,   CWnd*   pWnd,   UINT   nCtlColor)   
{ 
HBRUSH   hbr   =   CDialog::OnCtlColor(pDC,   pWnd,   nCtlColor); 
    
	if(nCtlColor==CTLCOLOR_EDIT)
	{
		const   MSG   *msg=GetCurrentMessage(); 
		if((HWND)msg-> lParam==GetDlgItem(IDC_EDIT1)->GetSafeHwnd()) 
			pDC-> SetBkColor(RGB(255,255,0)); 



	} 
//   TODO:   Change   any   attributes   of   the   DC   here 

//   TODO:   Return   a   different   brush   if   the   default   is   not   desired 
return   hbr; 
} 

[gotooker]

HBRUSH zdjc::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);

if(nCtlColor==CTLCOLOR_STATIC)
{
const MSG *msg=GetCurrentMessage();
if(int((msg->lParam))==IDC_EDIT1)
pDC->SetBkColor(RGB(255,255,0));
return m_hbr;
}
// TODO: Change any attributes of the DC here

// TODO: Return a different brush if the default is not desired
return hbr;
}
这样的话背景全黄了，还是没有区分开IDC_EDIT!

[gotooker]

不好意思我忘记说了，我的edit是只读的，所以都为staic的

[gotooker]

m_hbr是类中定义的一个刷子，已经设为黄色

你好，我试验成功了，请问GetDlgItem()后面的，GetsafeHwnd()有什么用出？

[gotooker]

多谢各位 不知道怎么加分，给完分回复就好了？？试验下

[菜牛]

你要判断是哪一个控件，用pWnd参数不就可以了？
if (pWnd->GetDlgCtrlID() == IDC_EDIT1)
....
