C語言模擬鍵盤程式碼如下：

int WINAPI WinMain(HINSTANCE hInstance,HINSTANCE hPrevInstance,LPSTR szCmdLine,int iCmdShow)

{

MSG msg;

if(!MyRegisterClass(hInstance))

{

return FALSE;

}

if(!InitInstance(hInstance,iCmdShow))

{

return FALSE;

}

while (GetMessage (&msg, NULL, 0, 0))

{

TranslateMessage (&msg);

DispatchMessage (&msg);

}

return msg.wParam;

}

//函式：ShowKey

//作用：實現在視窗中顯示按鍵資訊

void ShowKey (HWND hwnd, int iType,char *szMessage,WPARAM wParam,LPARAM lParam)

{

static char *szFormat[2] ={"%-14s %3d %c %6u %4d %5s %5s %6s %6s",

"%-14s %3d %c %6u %4d %5s %5s %6s %6s" };

char szBuffer[80];

HDC hdc;

ScrollWindowEx(hwnd, 0, -yChar, &rc,&rc,NULL,NULL,SW_INVALIDATE);

hdc = GetDC (hwnd);

SelectObject (hdc, GetStockObject (SYSTEM_FIXED_FONT));

TextOut (hdc,

xChar,

rc.bottom - yChar,

szBuffer,

wsprintf szBuffer,

szFormat[iType]。
