对话框背景色设置，重载OnPaint：

void CMonitorDialog::OnPaint()

{

CPaintDC dc(this); // device context for painting

// TODO: 在此处添加消息处理程序代码

// 不为绘图消息调用 CDialog::OnPaint()

/*CRect rect;

GetClientRect(rect);

CDC dcMem;

dcMem.CreateCompatibleDC(&dc);

CBitmap bmpBackgroud;

bmpBackgroud.LoadBitmap(IDB_BITMAP_MBACK);

BITMAP bitmap;

bmpBackgroud.GetBitmap(&bitmap);

CBitmap * pbmpold = dcMem.SelectObject(&bmpBackgroud);

dc.StretchBlt(0,0,rect.Width(),rect.Height(),&dcMem,0,0,bitmap.bmWidth,bitmap.bmHeight,SRCCOPY);*/

CRect rect;

GetClientRect(rect);

dc.FillSolidRect(rect,RGB(85,85,85)); //设置为黑色背景

//CDialog::OnPaint();

}

MFC简单皮肤颜色绘制（SetDialogBkColor不再被支持，看 WM_CTLCOLOR消息如何百变控件颜色）

[转]

WM_CTLCOLOR消息用来完成对EDIT, STATIC, BUTTON等控件设置背景和字体颜色, 其用法如下:

1.首先在自己需要设置界面的对话框上点击右键-->建立类向导-->加入WM_CTLCOLOR消息-->自动生成OnCtlColor()函数, 此函数可以对本对话框的控件的界面外观做修饰, 用法如下:

将类向导产生的函数做如下修改:

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

{

HBRUSH hbr = CDialog::OnCtlColor(pDC,pWnd, nCtlColor);

// TODO: Change any attributes of the DC here

// 设置显示字体

CFont * cFont=new CFont;

cFont->CreateFont(16,0,0,0,FW_SEMIBOLD,FALSE,FALSE,0,

ANSI_CHARSET,OUT_DEFAULT_PRECIS,

CLIP_DEFAULT_PRECIS,DEFAULT_QUALITY,

DEFAULT_PITCH&FF_SWISS,"Arial");

// 对特定的控件做修改

switch()

{

case CTLCOLOR_STATIC: //对所有静态文本控件的设置

{

pDC->SetBkMode(TRANSPARENT);

//设置背景为透明

pDC->SetTextColor(RGB(255,255,0)); //设置字体颜色

pWnd->SetFont(cFont); //设置字体

HBRUSH B = CreateSolidBrush(RGB(125,125,255));

//创建画刷

return (HBRUSH) B; //返回画刷句柄

}

case CTLCOLOR_EDIT: //对所有编辑框的设置

{

pDC->SetBkMode(TRANSPARENT);

pDC->SetTextColor(RGB(255,255,0));

pWnd->SetFont(cFont);

HBRUSH B = CreateSolidBrush(RGB(125,125,255));

return (HBRUSH) B;

}

default:

return CDialog::OnCtlColor(pDC,pWnd, nCtlColor);

}

}

注:case的类别有以下几种:

CTLCOLOR_BTN 按钮控件

CTLCOLOR_DLG 对话框

CTLCOLOR_EDIT 编辑框

CTLCOLOR_LISTBOX 列表框

CTLCOLOR_MSGBOX 消息框

CTLCOLOR_SCROLLBAR 滚动条

CTLCOLOR_STATIC 静态文本

2.你可能觉得对所有的控件使用统一的界面设置觉得不自由, 其实VC同样可以对特定的ID的控件进行设置, 方法如下:

switch (pWnd->GetDlgCtrlID())

{

//针对ID为IDC_CTL1, IDC_CTL2和IDC_CTL3的控件进行同样的设置

case IDC_CTL1:

case IDC_CTL2:

case IDC_CTL3:

{

pDC->SetBkMode(TRANSPARENT);

pDC->SetTextColor(RGB(255,255, 0));

pWnd->SetFont(cFont);

HBRUSH B = CreateSolidBrush(RGB(125,125,255));

return (HBRUSH) B;

}

default:

return CDialog::OnCtlColor(pDC, pWnd, nCtlColor);

}

HBrush用法

HBRUSH hbr;

第一种: hbr= CreateSolidBrush(RGB(255,0,0)); //单色的画刷

第二种: hbr= (HBRUSH)GetStockObject(BLACK_BRUSH); //只能取特定颜色的画刷,如BLACK_BRUSH,GRAY_BRUSH等刷

第三种: hbr= CreatePatternBrush(HBITMAP hbmp); //得到位图画刷

第四种: hbr = CreateHatchBrush(int fnStyle, COLORREF clrref) //创建一种带阴影的画刷

第五种: hbr= CreateBrushIndirect(LOGBRUSH); //通过LOGBRUSH结构体来取画刷

typedef struct tagLOGBRUSH { 

UINT lbStyle; //画刷类型

COLORREF lbColor; //颜色

LONG lbHatch; //阴影

} LOGBRUSH, *PLOGBRUSH;

第六种: hbr= HBRUSH CreateDIBPatternBrush( //通过与设备无关位图创建一个画刷

HGLOBAL hglbDIBPacked, // handle to DIB

UINT fuColorSpec // color table data

);

例如：

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

{

HBRUSH hbr = CFormView::OnCtlColor(pDC, pWnd, nCtlColor);

// TODO: Change any attributes of the DC here

if (pWnd->GetDlgCtrlID()==IDC_STATIC1)

{

pDC->SetTextColor(RGB(200,0,0));

pDC->SetBkColor(RGB(0,0,255));

static HBRUSH hBrush = CreateSolidBrush(RGB(222,0,255));

return hBrush;

}

// TODO: Return a different brush if the default is not desired

else 

return hbr;

}

改变对话框背景色

HBRUSH CDqfDlg::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)

{

CBrush *brush;

brush = new CBrush(RGB(221,221,221));

return (HBRUSH)(brush->m_hObject);

}

return hbr;

}

另外：

HBRUSH B = CreateSolidBrush(RGB(125,125,255));

return (HBRUSH) B;

可能会引起GDI资源泄漏，解决方法请参考：http://blog.csdn.NET/seven407/article/details/7497550

GroupBox

CRect rect; 

CWnd* pWndStatic=GetDlgItem(IDC_STA_SEND); 

    if(pWnd->GetDlgCtrlID()==IDC_STA_SEND && nCtlColor== CTLCOLOR_STATIC) 

    { 

    COLORREF backColor = RGB(255, 255, 182); 

pWndStatic->GetClientRect(&rect); 

pDC->FillSolidRect(&rect,backColor); 

    pDC->SetBkColor(backColor); 

//    pDC->SetBkMode(TRANSPARENT);//设置控件背景透明 

    return CreateSolidBrush(backColor);//创建背景刷子 

    } 

    else 

    { 

        return hbr; 

    } 

刚测试过可以pDC->SetBkColor(backColor);只是改变了GroupBox的标题的颜色，

用pDC->FillSolidRect(&rect,backColor);来改变区域的颜色。
