Vc/mfc How to set the background color of a dialog box

Method One: Call the member function of the CWinApp class SetDialogBkColor to implement. (This function is deprecated)

1	voidSetDialogBkColor(COLORREFclrCtlBk = RGB(192, 192, 192), COLORREFclrCtlText = RGB(0, 0, 0));

Where the first parameter of the function specifies the background color, the second parameter specifies the text color.

Add the following code in InitInstance ():

1	SetDialogBkColor(RGB(0,0,255),RGB(255,0,0));

It is important to note that SetDialogBkColor must be called before calling DoModal ().

This method has been verified by the author and cannot change the background of the dialog box

Method Two: Overload OnPaint (), which is the WM_PAINT message

1234	CRect   rect;   CPaintDC   dc(this);  GetClientRect(rect);  dc.FillSolidRect(rect,RGB(0,255,0));  //设置为绿色背景

Method Three: Overload OnCtlColor (cdc* PDC, cwnd* pWnd, UINT nCtlColor), which is the WM_CTLCOLOR message

. h header File Additions CBrush M_brush;

. cpp source file Additions M_brush. CreateSolidBrush (RGB (255,0,0));

onctlcolor (cdc*   pdc,   cwnd*   pwnd,   Code class= "CPP Color1 bold" >uint    nctlcolor)     Code class= "CPP Plain" >{  /*  downlink code to comment out         hbrush   hbr   =   Cdialog::onctlcolor (pDC,   pwnd,   nCtlColor);   */   return   m_brush;   Code class= "CPP Comments" >//back add red brush   }

Method Four: or overload OnCtlColor (cdc* PDC, cwnd* pWnd, UINT nCtlColor), which is the WM_CTLCOLOR message

. h header File Additions CBrush M_brush;

. cpp source file Additions M_brush. CreateSolidBrush (RGB (255,0,0));

OnCtlColor(CDC* pDC, CWnd* pWnd,UINT nCtlColor)  {   HBRUSH hbr   =   CDialog::OnCtlColor(pDC,   pWnd,   nCtlColor);   //在这加一条是否为对话框的判断语句      if(nCtlColor   ==CTLCOLOR_DLG)         returnm_brush;   //返加红色刷子    returnhbr;    }

Different paint brushes can be returned depending on the type of control to achieve different color settings for controls

1	这里大家要注意，OnCtlColor能改变Static等子控件的颜色，对于Button必须设置其属性Owner Draw为True,才能改变Button按钮背景色（CButton 文本的字体颜色并不能通过SetBkColor来改变，需要自己重绘CButton，在DrawItem中进行实现。
