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;
}
LRESULT CALLBACK WndProc(HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam) {

	static HMENU hMenu;
	static int idColor[5] = {WHITE_BRUSH, LTGRAY_BRUSH, GRAY_BRUSH, DKGRAY_BRUSH, BLACK_BRUSH };
	static int iSelection = IDM_WHITE;
	POINT point;

	switch(message) {

		case WM_CREATE:

			//All this does is creates the menu dynamically. I did this so I wouldn't have to worry about uploading a resource
			//script. It performs the same function. Note for a resource script you will have to explicitley say it is a 
			//popup menu.

			AppendMenu(hMenu, MF_STRING, IDM_WHITE, "White");
			AppendMenu(hMenu, MF_STRING, IDM_LTGRAY, "Light Gray");
			AppendMenu(hMenu, MF_STRING, IDM_GRAY, "Gray");
			AppendMenu(hMenu, MF_STRING, IDM_DKGRAY, "Dark Gray");
			AppendMenu(hMenu, MF_STRING, IDM_BLACK, "Black");

			return 0;
		case WM_RBUTTONUP:

			//The popupmenu will be displayed when the user right clicks so for this example I chose to track it with the 
			//right button up message
			
			point.x = LOWORD(lParam); // fugure out where the mouse was when the user clicked
			point.y = HIWORD(lParam); //
			
			ClientToScreen(hwnd, &point); //conver those coordinates into screen coordinates (relative -> absolute)

			TrackPopupMenu(hMenu, TPM_RIGHTBUTTON, point.x , point.y ,0, hwnd, NULL); //Display the popup menu and inform
			//windows we want to track the right mouse button. 

			return 0;
		case WM_COMMAND:

			switch(LOWORD(wParam)) {

				case IDM_WHITE:
				case IDM_LTGRAY:
				case IDM_GRAY:
				case IDM_DKGRAY:
				case IDM_BLACK:

					//This is just some menu handling logic that checks the menu item and then redraws the background.
					//Nothing really unique here.
					CheckMenuItem(hMenu, iSelection, MF_UNCHECKED);
					iSelection = LOWORD(wParam);
					CheckMenuItem(hMenu, iSelection, MF_CHECKED);

					SetClassLong(hwnd, GCL_HBRBACKGROUND, (LONG)GetStockObject(idColor[(LOWORD(wParam) - IDM_WHITE)]));
					InvalidateRect(hwnd, NULL, TRUE);
					return 0;
			}
			break;
		case WM_DESTROY:

			DestroyMenu(hMenu);
			PostQuitMessage(0);
			return 0;
	}
	return DefWindowProc(hwnd, message, wParam, lParam);
