共7步

0. 裝載CTRL+R導(dǎo)入一張位圖
1. 先要建一個(gè)類：
CBmpControl 給予 Static
2. 添加三個(gè)BMP相關(guān)的
class CBmpControl : public CStatic
{
// Construction
public:
BOOL LoadBitmapToControl(UINT uID);
CBitmap m_Bmp; //用這個(gè)畫
int m_BmpID;

3. 實(shí)現(xiàn)m_Bmp的畫圖

BOOL CBmpControl::LoadBitmapToControl(UINT uID)
{
int i = m_Bmp.LoadBitmap(uID);
m_BmpID = uID;
return TRUE;
}

void CBmpControl::OnPaint()
{
 CPaintDC dc(this); // device context for painting

// TODO: Add your message handler code here
m_Bmp.Detach();
m_Bmp.LoadBitmap(m_BmpID);

BITMAP bmInfo;
::GetObject( m_Bmp.m_hObject, sizeof(BITMAP), &bmInfo );
INT nWidth, nHeigh;
nWidth = bmInfo.bmWidth;
nHeigh = bmInfo.bmHeight;

CDC pDC;
pDC.CreateCompatibleDC(&dc);
pDC.SelectObject(&m_Bmp);
dc.BitBlt(0, 0, nWidth, nHeigh, &pDC, 0, 0, SRCCOPY);
// Do not call CStatic::OnPaint() for painting messages
}

4. 在工程中調(diào)用
// CBmpshowDlg dialog
#include "BmpControl.h"

class CBmpshowDlg : public CDialog
{
// Construction
public:
 CBmpshowDlg(CWnd* pParent = NULL); // standard constructor

// Dialog Data
//{{AFX_DATA(CBmpshowDlg)
enum { IDD = IDD_BMPSHOW_DIALOG};
CBmpControl m_Bmp;//------------------------------
// NOTE: the ClassWizard will add data members here
//}}AFX_DATA

5. 影射

void CBmpshowDlg::DoDataExchange(CDataExchange* pDX)
{
CDialog::DoDataExchange(pDX);
//{{AFX_DATA_MAP(CBmpshowDlg)
// NOTE: the ClassWizard will add DDX and DDV calls here
DDX_Control(pDX, IDC_BUTTON1, m_Bmp); // 畫到IDC_BUTTON1上
//}}AFX_DATA_MAP
}

6. 在需要顯示的地方
m_Bmp.LoadBitmapToControl(IDB_BITMAP1);
