プログラミングでマルチメディアキーボードの使い方（うぃんどうず）

なるほどWM_APPCOMMANDメッセージだ。

#include 

#include 
wchar_t* appname = L"just test";
LRESULT __stdcall wproc(HWND hWnd, UINT nMsg, WPARAM wp, LPARAM lp) {

	if(nMsg == WM_APPCOMMAND) {

		printf("key pressed:");

		switch(GET_APPCOMMAND_LPARAM(lp)) {

			case APPCOMMAND_MEDIA_PLAY_PAUSE:

				puts("play/pause");

				break;

			case APPCOMMAND_MEDIA_STOP:

				puts("stop");

				break;

			case APPCOMMAND_MEDIA_NEXTTRACK:

				puts("next");

				break;

			case APPCOMMAND_MEDIA_PREVIOUSTRACK:

				puts("previous");

				break;

		}

		return(TRUE);

	} else

		return DefWindowProc(hWnd, nMsg, wp, lp);

}
int main() {

	HWND hWnd;

	WNDCLASSW wc;

	BOOL bRet;

	MSG msg;

	

	ZeroMemory(&wc, sizeof(wc));

	wc.lpszClassName = appname;

	wc.hInstance = GetModuleHandle(0);

	wc.lpfnWndProc = wproc;

	

	RegisterClassW(&wc);

	hWnd = CreateWindowW(appname, appname, WS_OVERLAPPED, 0,0,0,0,0,0, GetModuleHandle(0), 0);

	ShowWindow(hWnd, SW_SHOWDEFAULT); 

	UpdateWindow(hWnd);

	while( (bRet = GetMessage( &msg, hWnd, 0, 0 )) != 0) { 

		if (bRet == -1) {

			break;

		} else {

			TranslateMessage(&msg); 

			DispatchMessage(&msg); 

		}

	}

	return(0);
