在CWinApp的继承中调用SetDialogBkColor

CWnd::OnCtlColor
This method is called by the framework 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.

afx_msg HBRUSH OnCtlColor(
CDC* pDC,
CWnd* pWnd,
UINT nCtlColor );
Parameters
pDC
Contains a pointer to the display context for the child window. May be temporary.
pWnd
Contains a pointer to the control asking for the color. May be temporary.
nCtlColor
Contains one of the following values, specifying the type of control:
CTLCOLOR_BTN Button control
CTLCOLOR_DLG Dialog box
CTLCOLOR_EDIT Edit control
CTLCOLOR_LISTBOX List-box control
CTLCOLOR_MSGBOX Message box
CTLCOLOR_SCROLLBAR Scroll-bar control
CTLCOLOR_STATIC Static control
Return Value
OnCtlColor must return a handle to the brush that is to be used for painting the control background.

Remarks
To change the text color, call the SetTextColor method with the desired red, green, and blue (RGB) values.

To change the background color of a single-line edit control, set the brush handle in both the CTLCOLOR_EDIT and CTLCOLOR_MSGBOX message codes, and call the CDC::SetBkColor method in response to the CTLCOLOR_EDIT code.

OnCtlColor will not be called for the list box of a drop-down combo box because the drop-down list box is actually a child of the combo box and not a child of the window. To change the color of the drop-down list box, create a CComboBox with an override of OnCtlColor that checks for CTLCOLOR_LISTBOX in the nCtlColor parameter. In this handler, the SetBkColor method must be used to set the background color for the text.

This method is called by the framework to allow your application to handle a Windows CE message. The parameters passed to your method reflect the parameters received by the framework when the message was received. If you call the base-class implementation of this method, that implementation will use the parameters originally passed with the message and not the parameters you supply to the method.

Example

// This OnCtlColor handler will change the color of a static control
// with the ID of IDC_MYSTATIC. The code assumes that the CMyDialog
// class has an initialized and created CBrush member named m_brush.
// The control will be painted with red text and a background
// color of m_brush.

HBRUSH CZilchDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
// Call the base class implementation first! Otherwise, it may
// undo what we are trying to accomplish here.
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);

// Are we painting the IDC_MYSTATIC control? We can use
// CWnd::GetDlgCtrlID() to perform the most efficient test.
if (pWnd->GetDlgCtrlID() == IDC_MYSTATIC)
{
// Set the text color to red.
pDC->SetTextColor(RGB(255, 0, 0));

// Set the background mode for text to transparent
// so background will show thru.
pDC->SetBkMode(TRANSPARENT);

// Return handle to our CBrush object.
hbr = m_brush;

HBRUSH CAllQueryDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
// TODO: Change any attributes of the DC here
// TODO: Return a different brush if the default is not desired
if(nCtlColor==CTLCOLOR_DLG) return m_hbrush1;
if (nCtlColor == CTLCOLOR_STATIC)
{
pDC->SetTextColor(RGB(10,10,100));
pDC->SetBkColor(RGB(195,195,146));
return m_hbrush1;
}

if (nCtlColor == CTLCOLOR_EDIT)
{
pDC->SetBkColor(RGB(245,245,220));
return m_hbrush2;
}
return hbr;
}

OnCtlColor 函数可以在ClassWizard中添加
HBRUSH m_hbrush1=CreateSolidBrush(RGB(195,195,146));
HBRUSH m_hbrush2=CreateSolidBrush(RGB(245,245,220));

SetBkcolor(....)函数可以实现
