方法1:

1) 更改属性Picture Control属性

2) 直接关联上image: 设置Image属性

3) 更改type为Bitmap

方法2:(PictureEx类网上搜)

1) 添加控件变量为PictureEx对象

2) 直接m_pic1.LoadBitmap(IDB_BITMAP1); 

示例:

1. 关联 Picture Control 对象: m_stPicture

2. 添加2个BMP资源 IDB_BITMAP1, IDB_BITMAP2

3. 定义: HBITMAP m_hBitmap;

4. 一开始显示图片

BOOL CShowBmpDlg::OnInitDialog()

{

CDialog::OnInitDialog();

......

//显示图片

m_hBitmap = (HBITMAP)LoadImage(AfxGetInstanceHandle(), MAKEINTRESOURCE(IDB_BITMAP1), IMAGE_BITMAP, 0, 0, LR_LOADMAP3DCOLORS);

m_stPicture.ModifyStyle(0xF, SS_BITMAP);

m_stPicture.SetBitmap(m_hBitmap);

return TRUE;  // 除非设置了控件的焦点，否则返回 TRUE

}

5. 切换图片

void CShowBmpDlg::OnBnClickedOk()

{

static int nId = 0;

nId++;

if (NULL != m_hBitmap)

{

::DeleteObject(m_hBitmap);

m_hBitmap = NULL;

}

int nPicId = nId = nId % 2 ? IDB_BITMAP2 : IDB_BITMAP1;

m_hBitmap = (HBITMAP)LoadImage(AfxGetInstanceHandle(), MAKEINTRESOURCE(nPicId), IMAGE_BITMAP, 0, 0, LR_LOADMAP3DCOLORS);

m_stPicture.ModifyStyle(0xF, SS_BITMAP);

m_stPicture.SetBitmap(m_hBitmap);

}
