Ciao ragazzi ho cercato di compilare questo codice (molto grezzo) per fare comparire un video su finestra......
mi dice che devo usare la dll per MFC....ma se la uso mi dice che non devo includere winodows.h.....cosa posso fare?

(Il codice è per 4/5 quello di base per una windows application in visual c++ 2010)



// AVI.cpp : Defines the entry point for the application.
//

#include "stdafx.h"
#include "AVI.h"

#define MAX_LOADSTRING 100

// Global Variables:
HINSTANCE hInst; // current instance
TCHAR szTitle[MAX_LOADSTRING]; // The title bar text
TCHAR szWindowClass[MAX_LOADSTRING]; // the main window class name

// Forward declarations of functions included in this code module:
ATOM MyRegisterClass(HINSTANCE hInstance);
BOOL InitInstance(HINSTANCE, int);
LRESULT CALLBACK WndProc(HWND, UINT, WPARAM, LPARAM);

// Perform application initialization:

Ciao ragazzi ho cercato di compilare questo codice (molto grezzo) per fare comparire un video su finestra......
mi dice che devo usare la dll per MFC....ma se la uso mi dice che non devo includere winodows.h.....cosa posso fare?

Mi dice ... chi? cosa? quando? dove? :D

A parte questo, vedo una CreateThread ad ogni WM_PAINT ... è una cosa poco sensata ....

Beh la cosa poco sensata è vera....xDxD
comunque a parte questa idiozia....visual c++ non me lo lascia compilare....perchè io per usare cAnimCtrl devo includere afxcmn.h...quindi anche afx.h....il cui mi da problemi.....forse non devo usare cAnimCtrl per mostrare i video.....ma non trovo di meglio..... :cry:

allora lasciamo perdere questo codice....avete qualche altra idea per riprodurre un video avi (o non avi) su una finestra?
