VC顯示BMP圖片

 

方法1:

1) 更改屬性Picture Control屬性

2) 直接關聯上image: 設定Image屬性

3) 更改type為Bitmap

方法2:(PictureEx類網上搜)

1) 添加控制項變數為PictureEx對象

2) 直接m_pic1.LoadBitmap(IDB_BITMAP1); 

樣本:

1. 關聯 Picture Control 對象: m_stPicture

2. 添加2個BMP資源 IDB_BITMAP1, IDB_BITMAP2

3. 定義: HBITMAPm_hBitmap;

4. 一開始顯示圖片

BOOL CShowBmpDlg::OnInitDialog()

{

CDialog::OnInitDialog();

......

//顯示圖片

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;  // 除非設定了控制項的焦點，否則返回 TRUE

}

5. 切換圖片

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);

}
