3. 메시지 비프

비프음을 내는 출력을 낼 수 도 있다.

 

BOOL MessageBeep(UINT uType);

docs.microsoft.com/en-us/windows/win32/api/winuser/nf-winuser-messagebeep

간단하게 매개변수에 0xFFFFFFFF를 넣으면 경고음이 스피커를 통해 출력된다.

 

#include <windows.h>
 
LRESULT CALLBACK WndProc(HWND, UINT, WPARAM, LPARAM);
HINSTANCE g_hInst;
LPCTSTR lpszClass = TEXT("TextOut");
 
int APIENTRY WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance
    , LPSTR lpszCmdParam, int nCmdShow)
{
    HWND hWnd;
    MSG Message;
    WNDCLASS WndClass;
    g_hInst = hInstance;
 
    WndClass.cbClsExtra = 0;
    WndClass.cbWndExtra = 0;
    WndClass.hbrBackground = (HBRUSH)GetStockObject(WHITE_BRUSH);
    WndClass.hCursor = LoadCursor(NULL, IDC_ARROW);
    WndClass.hIcon = LoadIcon(NULL, IDI_APPLICATION);
    WndClass.hInstance = hInstance;
    WndClass.lpfnWndProc = (WNDPROC)WndProc;
    WndClass.lpszClassName = lpszClass;
    WndClass.lpszMenuName = NULL;
    WndClass.style = CS_HREDRAW | CS_VREDRAW;
    RegisterClass(&WndClass);
 
    hWnd = CreateWindow(lpszClass, lpszClass, WS_OVERLAPPEDWINDOW,
        CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT,
        NULL, (HMENU)NULL, hInstance, NULL);
    ShowWindow(hWnd, nCmdShow);
 
    while (GetMessage(&Message, 0, 0, 0)) {
        TranslateMessage(&Message);
        DispatchMessage(&Message);
    }
    return Message.wParam;
}
 
LRESULT CALLBACK WndProc(HWND hWnd, UINT iMessage, WPARAM wParam, LPARAM lParam)
{
    HDC hdc;
    PAINTSTRUCT ps;
    switch (iMessage) {
    case WM_DESTROY:
        PostQuitMessage(0);
        return 0;
    case WM_LBUTTONDOWN:
        MessageBeep(0xFFFFFFFF);
        return 0;
    }
    return(DefWindowProc(hWnd, iMessage, wParam, lParam));
}

 

마우스 좌클릭을 할 때마다 경고음이 스피커를 통해서 나오게 된다.
