Help for change a program in C++ for AVI file

please how to change this program for read all size for AVI file? Ce programme permet d'aficher un fichier AVI bien précis width= 48 and lenght=80, so the size is 48x80x3= 117Ko alors si en change la taille du video il ne peut pas marché, il affiche dans un 1er temps une image bmp inversé, au dessous de cette image il affiche 5 frames, et au dessous il affiche le video, mais just pour cette taille, alors comment faire si je veux changer le program pour lire tout les tailles des fichiers AVI? si quelqu'un peut m'aider je vous remercie vivement. // Get pointers to the info structure & the bits pointer = (BYTE *) prifffile ; the pointer here is static I think we must change into dynamic for read all size //sstring[0] = * (pointer+4095); pointer = pointer + 4096+11; // here we can change the color of bitmap background hdc = BeginPaint (hwnd, &ps) ; //draw a frame for(i=0;i<48;i++) for(j=0;j<80;j++) if((0.299*(*(pointer+2+i*80*3+j*3))+0.587*(*(pointer+1+i*80*3+j*3))+0.114*(*(pointer +i*80*3+j*3)))<100) SetPixel(hdc,j+50,i+50,RGB(255,0,0)); //draw 5 frames parally for(m=0;m<5;m++){// this is a movie for(i=0;i<48;i++) for(j=0;j<80;j++) SetPixel(hdc,j+100*m+50,i+150,RGB(*(pointer+2 + j*3 +(48-i)*80*3), *(pointer+1 + j*3 +(48-i)*80*3), *(pointer + j*3 +(48-i)*80*3))); pointer = pointer + 11520*m+8*m; } pointer = (BYTE *) prifffile ; //let the pointer to pointer the begining again pointer = pointer + 4096+11; //let the pointer to point at the bitmap data //draw several frames to make a animation as movie for(n=0;n<5;n++){ // repeat 5 times for(m=0;m<5;m++){// this is a movie for(i=0;i<48;i++) for(j=0;j<80;j++) SetPixel(hdc,j+50,i+250,RGB(*(pointer+2 + j*3 +(48-i)*80*3), *(pointer+1 + j*3 +(48-i)*80*3), *(pointer + j*3 +(48-i)*80*3))); pointer = pointer + 11520*m+8*m; Sleep(300); // set a time interval to make the movie natural } pointer = (BYTE *) prifffile ; //let the pointer to pointer the begining again pointer = pointer + 4096+11; //let the pointer to point at the bitmap data } // repeat 10 times EndPaint (hwnd, &ps) ; // show a dialogbox to tell you that the testing ends MessageBox(hwnd,TEXT("displaying ends/ÑÝÊ??áÊø"),sstring,0); return 0 ; ================================================================================================================================================ ||Program|| ------- /*---------------------------------------------- SHOWDIB1.C -- Shows a DIB in the client area (c) Charles Petzold, 1998 ----------------------------------------------*/ #include #include #include #include "dibfile.h" #include "resource.h" LRESULT CALLBACK WndProc (HWND, UINT, WPARAM, LPARAM) ; TCHAR szAppName[] = TEXT ("ShowDib1") ; int WINAPI WinMain (HINSTANCE hInstance, HINSTANCE hPrevInstance, PSTR szCmdLine, int iCmdShow) { HACCEL hAccel ; HWND hwnd ; MSG msg ; WNDCLASS wndclass ; wndclass.style = CS_HREDRAW | CS_VREDRAW ; wndclass.lpfnWndProc = WndProc ; wndclass.cbClsExtra = 0 ; wndclass.cbWndExtra = 0 ; wndclass.hInstance = hInstance ; wndclass.hIcon = LoadIcon (NULL, IDI_APPLICATION) ; wndclass.hCursor = LoadCursor (NULL, IDC_ARROW) ; wndclass.hbrBackground = (HBRUSH) GetStockObject (WHITE_BRUSH) ; wndclass.lpszMenuName = szAppName ; wndclass.lpszClassName = szAppName ; if (!RegisterClass (&wndclass)) { MessageBox (NULL, TEXT ("This program requires Windows NT!"), szAppName, MB_ICONERROR) ; return 0 ; } hwnd = CreateWindow (szAppName, TEXT ("display an avi picture and an avi movie"), WS_OVERLAPPEDWINDOW, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, NULL, NULL, hInstance, NULL) ; ShowWindow (hwnd, iCmdShow) ; UpdateWindow (hwnd) ; hAccel = LoadAccelerators (hInstance, szAppName) ; while (GetMessage (&msg, NULL, 0, 0)) { if (!TranslateAccelerator (hwnd, hAccel, &msg)) { TranslateMessage (&msg) ; DispatchMessage (&msg) ; } } return msg.wParam ; } LRESULT CALLBACK WndProc (HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam) { //////////////////////////////////// static BITMAPINFO * pbmi ; static BYTE * pBits ; //////////////////////////////////// static RIFFLIST * prifffile ; static AVIMAINHEADER * pavimh; static AVISTREAMHEADER * pavish ; static BYTE * pointer ; ///////////////////////////////////////////////////////////////////// static int cxClient, cyClient, cxDib, cyDib ; static TCHAR szFileName [MAX_PATH], szTitleName [MAX_PATH] ; BOOL bSuccess ; HDC hdc ; PAINTSTRUCT ps ; int i,j,m,n; ////////////////////////////////////////////////////////////////////// // RIFF is the first 4 letters of a riff file. avi file is a riff file static TCHAR sstring[] = {'R','I','F','F','\0'}; ////////////////////////////////////////////////////////////////////// switch (message) { case WM_CREATE: DibFileInitialize (hwnd) ; return 0 ; case WM_SIZE: cxClient = LOWORD (lParam) ; cyClient = HIWORD (lParam) ; return 0 ; case WM_INITMENUPOPUP: EnableMenuItem ((HMENU) wParam, IDM_FILE_SAVE, prifffile ?
