ProgressBar [ besoin d'aide ]

Question

Bonjours, Je debute en c++ , et je voudrais savoir comment on fait pour faire une ProgressBar sous Dev-c++. Je ne sait meme pas ou l'appeler et tout se qui sans suit XD . Donc si quelqu'un pourrait m'aider se serait sympa. Je vous depose mon code . fichier main.cpp : #include #include #include #pragma comment( lib, "winmm.lib" ) #include #pragma comment(lib,"Wininet.lib" ) #include "main.h" typedef int (*TestNetFunction) (int); typedef int (*TestDLLFunction) (int); typedef BOOL (WINAPI *PF_INETGETCONNECTEDSTATE)(LPDWORD, DWORD); using namespace std; /* Declare Windows procedure */ LRESULT CALLBACK WindowProcedure (HWND, UINT, WPARAM, LPARAM); /* Make the class name into a global variable */ char szClassName[ ] = "WindowsApp"; int WINAPI WinMain (HINSTANCE hThisInstance, HINSTANCE hPrevInstance, LPSTR lpszArgument, int nFunsterStil) { HWND hwnd; /* This is the handle for our window */ MSG messages; /* Here messages to the application are saved */ WNDCLASSEX wincl; /* Data structure for the windowclass */ int Chargement(); BOOL bConnected; DWORD dwFlags; /* The Window structure */ wincl.hInstance = hThisInstance; wincl.lpszClassName = szClassName; wincl.lpfnWndProc = WindowProcedure; /* This function is called by windows */ wincl.style = CS_DBLCLKS; /* Catch double-clicks */ wincl.cbSize = sizeof (WNDCLASSEX); /* Use default icon and mouse-pointer */ wincl.hIcon = LoadIcon (hThisInstance, "ICON"); wincl.hIconSm = LoadIcon (hThisInstance, "ICONE"); wincl.hCursor = LoadCursor (NULL, IDC_ARROW); wincl.lpszMenuName = NULL; /* No menu */ wincl.cbClsExtra = 0; /* No extra bytes after the window class */ wincl.cbWndExtra = 0; /* structure or the window instance */ /* Use Windows's default color as the background of the window */ wincl.hbrBackground = (HBRUSH) COLOR_BACKGROUND; /* Register the window class, and if it fails quit the program */ if (!RegisterClassEx (&wincl)) return 0; /* The class is registered, let's create the program*/ hwnd = CreateWindowEx ( 0, /* Extended possibilites for variation */ szClassName, /* Classname */ "Fenètre de chargement et de vérification des données ...", /* Title Text */ WS_OVERLAPPED, /* default window */ CW_USEDEFAULT, /* Windows decides the position */ CW_USEDEFAULT, /* where the window ends up on the screen */ 591, /* The programs width */ 530, /* and height in pixels */ HWND_DESKTOP, /* The window is a child-window to desktop */ NULL, /* No menu */ hThisInstance, /* Program Instance handler */ NULL /* No Window Creation data */ ); /* Make the window visible on the screen */ int sound; sound = PlaySound("Demarage.wav", hThisInstance, SND_ASYNC); ShowWindow(hwnd, nFunsterStil); /* Run the message loop.

Salut,

La barre de progression est un "contrôle commun". Donc faut se lier à comctl32.lib, faire un include de commctrl.h et appeler InitCommonControlsEx. Ensuite il faut lire cette page de la msdn qui explique comment s'en servir, avec exemple.
