How to make a right-click menu ?

Hi, I'm making a small program with VC++ 6.0. My program needs a right-click menu and I don't know how to do it. Please help me !

Well, do you know how to make a menu? BTW is this windows based or console based?

Wouldn't console based be impossible? Because consoles are impossible for right-click events.

It's possible in Windows, and covered in part 5 of Adrianxw's console programming tutorial.

If we are talking windows then below is a sample program that demonstrates the creation and presentation of a popup menu. I created the menu during runtime simply so I wouldn't have to worry about uploading a resource script. I hope this helps some.

Code:

---

#include <windows.h>

//Just some definitions that we will use later on to
//create the popup menu
#define IDM_WHITE        4001
#define IDM_LTGRAY        4002
#define IDM_GRAY        4003
#define IDM_DKGRAY        4004
#define IDM_BLACK        4005

LRESULT CALLBACK WndProc(HWND, UINT, WPARAM, LPARAM);



int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, PSTR szCmdLine, int iCmdShow) {

        HWND hwnd;
        MSG msg;
        WNDCLASS wc;
        TCHAR szAppName[] = TEXT("PopMenu");

        wc.cbClsExtra = 0;
        wc.cbWndExtra = 0;
        wc.hbrBackground = (HBRUSH)GetStockObject(WHITE_BRUSH);
        wc.hCursor = LoadCursor(NULL, IDC_ARROW);
        wc.hIcon = LoadIcon(NULL, IDI_APPLICATION);
        wc.hInstance = hInstance;
        wc.lpfnWndProc = WndProc;
        wc.lpszClassName = szAppName;
        wc.lpszMenuName = NULL;
        wc.style = CS_HREDRAW | CS_VREDRAW;

        if(!RegisterClass(&wc)) {
                MessageBox(NULL, TEXT("Could not register class"), szAppName, MB_ICONERROR);
                return 0;
        }

        hwnd = CreateWindow(szAppName, TEXT("Popup Menu Demo"), WS_OVERLAPPEDWINDOW, CW_USEDEFAULT, CW_USEDEFAULT,
                                                CW_USEDEFAULT, CW_USEDEFAULT, NULL, NULL, hInstance, NULL);

        ShowWindow(hwnd, iCmdShow);
        UpdateWindow(hwnd);

        while(GetMessage(&msg, NULL, 0, 0)) {
               
                TranslateMessage(&msg);
                DispatchMessage(&msg);
        }

        return msg.wParam;
}

                        hMenu = CreatePopupMenu();

                        AppendMenu(hMenu, MF_STRING, IDM_WHITE, "White");
