我一直在接受如何制作键盘加速键的培训，但是当我尝试时，它不起作用.. 这是代码:
资源文件::
#include "resource.h"
IDM_MAINMENU MENU
BEGIN
POPUP "&File"
BEGIN
POPUP "&Program"
BEGIN
MENUITEM "LED O&N", IDM_PROGRAM_LED_ON
MENUITEM "LED O&FF", IDM_PROGRAM_LED_OFF
MENUITEM "LED &BLINK", IDM_PROGRAM_LED_BLINK
END
MENUITEM SEPARATOR
MENUITEM "E&xit", IDM_FILE_EXIT
END
POPUP "&Help"
BEGIN
MENUITEM "&Info", IDM_INFO
END
END
app_icon ICON "untitled.ico"
IDA_ACCEL_TABLE ACCELERATORS
BEGIN
"x", IDA_CTRL_X, CONTROL, VIRTKEY
END
头文件:
#define app_icon 1
#define IDM_MAINMENU 2
#define IDM_FILE_EXIT 3
#define IDA_ACCEL_TABLE 4
#define IDD_DIALOG 5
#define IDA_CTRL_X 6
#define IDM_PROGRAM_LED_OFF 7
#define IDM_PROGRAM_LED_BLINK 8
#define IDM_PROGRAM_LED_ON 9
#define IDM_INFO 10
主 .exe 文件::
#include <windows.h>
#include "resource.h"
#include "define.h"
LRESULT CALLBACK WinProc(HWND hWnd,UINT message,WPARAM wParam,LPARAM lParam);
int WINAPI WinMain(HINSTANCE hInst, HINSTANCE hPrevInst, LPSTR lpCmdLine, int nShowCmd){
window win;
MSG msg;
HMENU hMenu;
hMenu = LoadMenu(hInst, MAKEINTRESOURCE(IDM_MAINMENU));
HACCEL hAccel;
hAccel = LoadAccelerators(hInst, MAKEINTRESOURCE(IDA_ACCEL_TABLE));
win.cbClsExtra = NULL; //Additional parameters
win.cbWndExtra = NULL; //Additional parameters
win.hbrBackground = (HBRUSH)COLOR_WINDOW ; //Sets background color for the window
win.hCursor = LoadCursor(NULL, IDC_ARROW); //The cursor that will appear in the window
win.hIcon = LoadIcon(hInst, MAKEINTRESOURCE(app_icon)); //Icon for the window
win.hInstance = hInst; //Handle to the application instance
win.lpszClassName = "Window Class"; //The unique name of the window class
win.lpszMenuName = NULL; //Used for menus
win.style = NULL; //The look and feel of the window
win.lpfnWndProc=(WNDPROC)WinProc; //The callback procedure (more on that later)
RegisterClass(&win);
HWND hwnd = CreateWindow("Window Class", "Atmel Microcontroller Programmer", WS_OVERLAPPEDWINDOW, 550, 300, 350, 260, NULL, hMenu, hInst, NULL);
ShowWindow(hwnd, SW_SHOWNORMAL);
while(GetMessage(&msg, NULL, 0, 0)){
if(!TranslateAccelerator(hwnd, hAccel, &msg)){
TranslateMessage(&msg);
DispatchMessage(&msg);
}
}
return 0;
}
LRESULT CALLBACK WinProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam){
switch (message){
case WM_CREATE:{
CreateWindow("BUTTON", "LED on", WS_VISIBLE | WS_CHILD | WS_BORDER, 20, 20, 70, 50, hWnd, (HMENU)1, NULL, NULL);
CreateWindow("BUTTON", "LED off", WS_CHILD | WS_VISIBLE | WS_BORDER, 125, 80, 70, 50, hWnd, (HMENU)2, NULL, NULL);
CreateWindow("BUTTON", "LED blink", WS_CHILD | WS_VISIBLE | WS_BORDER, 240, 140, 70, 50, hWnd, (HMENU)3, NULL, NULL);
break;
}
case WM_COMMAND:{
if(wParam == 1){
system("avrdude");
}
if(wParam == 2){
system("avrdude");
}
if(wParam == 3){
system("avrdude");
}
if (wParam == IDA_CTRL_X){
MessageBeep(message);
}
break;
}
case WM_DESTROY:{
PostQuitMessage(0);
return 0;
break;
}
default:{
return DefWindowProc(hWnd, message, wParam, lParam);
}
}
}
这是我一直在使用的所有文件，但还有一个头文件，我在其中定义了一些小东西并添加了注释以供我记住，但它太大了，我定义的最重要的东西是消息MessageBox 和窗口为 WNDCLASS
我知道阅读所有这些内容需要付出很多努力，但我真的需要帮助，非常感谢大家。 =D

是的，如果你问我正在尝试从计算机制作一个程序来控制我将用微 Controller 制作的电路，但我还没有做十六进制程序或电路，这就是我开始的。
最佳答案
我相信你的错误在这里:
if (wParam == IDA_CTRL_X){
MessageBeep(message);
}
当WM_COMMAND 的消息源是加速器时，wParam 的高位字是1，低位字是加速器标识符。如果是菜单，则高位字是 0，低位字是菜单标识符。 (参见 reference。)
所以你要做的是:
switch (message)
{
case WM_COMMAND:
wmId = LOWORD(wParam);
wmEvent = HIWORD(wParam);
switch(wmId)
{
case IDA_CTRL_X:
MessageBeep(message);
break;
}
break;
}
