1.插入一个Bitmap的资源图片，假设资源名称为：IDC_BITMAP1

2.在CXXXDialog::OnPaint()中实现：

void

CMyDialogDlg::OnPaint()

{

if

(IsIconic())

{

CPaintDC dc(

this

);

//

用于绘制的设备上下文

SendMessage(WM_ICONERASEBKGND, reinterpret_cast

<

WPARAM

>

(dc.GetSafeHdc()),

0

);

//

使图标在工作区矩形中居中

int

cxIcon

=

GetSystemMetrics(SM_CXICON);

int

cyIcon

=

GetSystemMetrics(SM_CYICON);

CRect rect;

GetClientRect(

&

rect);

int

x

=

(rect.Width()

-

cxIcon

+

1

)

/

2

;

int

y

=

(rect.Height()

-

cyIcon

+

1

)

/

2

;

//

绘制图标

dc.DrawIcon(x, y, m_hIcon);

}

else

{

//

//

给窗体添加背景

//

CPaintDC dc(

this

);

CRect rc;

GetClientRect(

&

rc);

CDC dcMem;

dcMem.CreateCompatibleDC(

&

dc);

CBitmap bmpBackground;

bmpBackground.LoadBitmap(IDB_BITMAP1);

BITMAP bitmap;

bmpBackground.GetBitmap(

&

bitmap);

CBitmap

*

pbmpPri

=

dcMem.SelectObject(

&

bmpBackground);

dc.StretchBlt(

0

,

0

,rc.Width(), rc.Height(),

&

dcMem,

0

,

0

,bitmap.bmWidth, bitmap.bmHeight, SRCCOPY);

}

}
