MFC （7）在pic控件里加载一幅图片源码

CBitmap m_bmp;
HBITMAP   hBitmap5;
hBitmap5 = (HBITMAP)::LoadImage( NULL, "res//0x00304EE6.bmp",                           // 图片全路径
IMAGE_BITMAP,                          // 图片格式
0,0,
LR_LOADFROMFILE|LR_CREATEDIBSECTION);  // 注意LR_LOADFROMFILE

//获取加载的位图信息
m_bmp.Attach(hBitmap5);
DIBSECTION ds;
BITMAPINFOHEADER &bminfo = ds.dsBmih;
m_bmp.GetObject(sizeof(ds),&ds);

int cx = bminfo.biWidth;   //获取图像宽度
int cy = bminfo.biHeight;  //获取图像高度

//调整图像大小符合空间要求，使得其正好显示一张图片
CRect rect;
GetDlgItem(IDC_STATIC_1)->GetWindowRect(&rect);
ScreenToClient(&rect);
GetDlgItem(IDC_STATIC_1)->MoveWindow(rect.left,rect.top,cx,cy,true);   //调整大小

CPaintDC dc2(GetDlgItem(IDD_VINCENT1));
CRect rcclient;
GetDlgItem(IDC_STATIC_1)->GetClientRect(&rcclient);
CDC memdc;
memdc.CreateCompatibleDC(&dc2);
CBitmap bitmap;
bitmap.CreateCompatibleBitmap(&dc2,rcclient.Width(),rcclient.Height());
memdc.SelectObject(&bitmap);

CWnd::DefWindowProc(WM_PAINT,(WPARAM)memdc.m_hDC,0);

CDC maskdc;
maskdc.CreateCompatibleDC(&dc2);
CBitmap maskbitmap;
