vc动态加载位图.doc

动态加载位图就是在运行中随意显示某图片吧原型：int WINAPI icePub_dispImg(HWND hWnd,char *strImgFilename,int x,int y)输入：hWnd 窗体或控件句柄strImgFilename 待显示的图片文件名 x x坐标 y y坐标输出： typedef int (WINAPI ICEPUB_DISPIMG)(HWND hWnd,char *strImgFilename,int x,int y); ICEPUB_DISPIMG *icePub_dispImg = 0; HINSTANCE hDLLDrv = LoadLibrary(icePubDll.dll); if(hDLLDrv) icePub_dispImg = (ICEPUB_DISPIMG *)GetProcAddress(hDLLDrv, icePub_dispImg); if(icePub_dispImg != NULL) icePub_dispImg(m_hWnd,b.png,10,10);/ icePub_dispImg(m_ctrlText.m_hWnd,b.jpg,0,0); if(hDLLDrv) FreeLibrary(hDLLDrv); 追问谢谢！我是刚学不久，我要在按钮上贴图片，用程序的参数而改变按钮图片，也就是显示不同的图片，我要怎么做，谢谢！回答冒汗，那用按钮直接装载图片资源比较方便，但能不能装载图片文件就不知了.追问谢谢！回答不用客气VC 动态加载位图第一步：/位图加载 if(m_BitMap.m_hObject!=NULL) m_BitMap.DeleteObject(); HBITMAP hbmp = (HBITMAP):LoadImage(AfxGetInstanceHandle(),位图文件的绝对路径, IMAGE_BITMAP,0,0,LR_CREATEDIBSECTION|LR_LOADFROMFILE); if (hbmp=NULL) AfxMessageBox(加载位图失败!); return FALSE; m_BitMap.Attach(hbmp); BITMAPINFOHEADER bminfo; m_BitMap.GetObject(sizeof(bminfo),&bminfo); m_nBmpWidth = bminfo.biWidth; /获取图像宽度 m_nBmpHeight = bminfo.biHeight; /获取图像高度第二步：把图片画出来，在OnPaint()函数中添加：CPaintDC dc(this); / device context for painting CDC DcPicture; DcPicture.CreateCompatibleDC(&dc);/创建兼容DC CBitmap *pOldBitMap = DcPicture.SelectObject(&m_BitMap); CRect rectPicture; GetDlgItem(IDC_PICTUREWND)-GetWindowRect(&rectPicture); / ScreenToClient(&rectPicture); dc.StretchBlt(rectPicture.left,rectPicture.top,rectPicture.Width(),rectPicture.Height(), &DcPicture,0,0,m_nBmpWidth,m_nBmpHeight,SRCCOPY
