win32 windows application and want to capture full screen and remove the border of window displayed any one tell me how can i do so if this window capture the mouse keyboard controls then it will be ideal?

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

#include "stdafx.h"
#include "MonitorScreen.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

// Perform application initialization: if (!InitInstance (hInstance, nCmdShow)) { return FALSE; }

hAccelTable = LoadAccelerators(hInstance, MAKEINTRESOURCE(IDC_MONITORSCREEN));

// Main message loop: while (GetMessage(&msg, NULL, 0, 0)) { if (!TranslateAccelerator(msg.hwnd, hAccelTable, &msg)) { TranslateMessage(&msg); DispatchMessage(&msg); } }

I'm going to assume you don't actually want to capture the screen, your question cannot make sense. I'm guessing you simply want to make your window maximized to occupy the full screen. Put the template generated code back the way it was, simply change the ShowWindow call:

 ShowWindow(hWnd, SW_MAXIMIZE);
