MFC CEdit自绘时遇到的问题，求帮助

[xiao___sun]

我做了一个类CGreyEditControl基于CEdit来实现编辑框控件的自绘，但是在自绘时遇到了个问题，如图：

编辑框中文字部分是白的，我现在想要它变成RGB(63, 63, 70)。
要求：父窗口中不做任何修改，只在CGreyEditControl中做修改实现

以下是代码：（部分）

//父窗口CPP WM_CTLCOLOR -> OnCtlColor
HBRUSH CGreyDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
	HBRUSH hbr = CDialogEx::OnCtlColor(pDC, pWnd, nCtlColor);
	
	if (pWnd->GetDlgCtrlID() != MY_EDIT)
	{
		pDC->SetBkColor(RGB(37, 37, 38));
		pDC->SetBkMode(TRANSPARENT);
		pDC->SetTextColor(RGB(255, 255, 255));
		return CreateSolidBrush(RGB(37, 37, 38));
	}

	return hbr;
}

补充下，CtlColor(...)调试时有调用过，但是对结果没有作用

[schlafenhamster]

CWnd::OnCtlColor
afx_msg HBRUSH OnCtlColor( CDC* pDC, CWnd* pWnd, UINT nCtlColor );

Remarks
The framework calls this member function when a child control is about to be drawn. Most controls send this message to their parent (usually a dialog box) to prepare the pDC for drawing the control using the correct colors.

[schlafenhamster]

因为是反射消息
HBRUSH CMyEdit::CtlColor(CDC* pDC, UINT nCtlColor)
{
// TODO: Change any attributes of the DC here

// TODO: Return a non-NULL brush if the parent's handler should not be called return NULL;
}

[schlafenhamster]

所以 反射 CtlColor ， 和 OnCtlColor 父窗口 不能 同时 有。

引用 4 楼 schlafenhamster 的回复:

懂了，就是你父窗口OnCtlColor了，子窗口再CtlColor就是没用了吧。但是有没有解决方法？不删除父窗口的OnCtlColor

[schlafenhamster]

把 功能 都 放 CtlColor 里

// TODO: Return a non-NULL brush if the parent's handler should not be called return NULL;

OnCtlColor 不会被调用
