设置应用权限

首先列出需要的函数

1.OpenProcessToken

2.AdjustTokenPrivileges

3. LookupPrivilegeValue

实现1

BOOL SetPrivilege(LPCTSTR lpszPrivilege, BOOL bEnablePrivilege) { 第一个参数为特权名，第二个为打开或者关闭
    TOKEN_PRIVILEGES tp;
    HANDLE hToken;
    LUID luid;

    if (!OpenProcessToken(GetCurrentProcess(),
        TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &hToken))
        return FALSE;

    if (!LookupPrivilegeValue(NULL,       
        lpszPrivilege, 
        &luid))       
        return FALSE;

    tp.PrivilegeCount = 1;
    tp.Privileges[0].Luid = luid;
    if (bEnablePrivilege)
        tp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;
    else
        tp.Privileges[0].Attributes = 0;


    if (!AdjustTokenPrivileges(hToken, FALSE, &tp,
        sizeof(TOKEN_PRIVILEGES), (PTOKEN_PRIVILEGES)NULL, (PDWORD)NULL))
        return FALSE;

    if (GetLastError() == ERROR_NOT_ALL_ASSIGNED)
        return FALSE;

    return TRUE;
}

实现2

DWORD _EnableNTPrivilege(LPCTSTR szPrivilege, DWORD dwState)
{
    DWORD dwRtn = 0;
    HANDLE hToken;
    if (OpenProcessToken(GetCurrentProcess(),
        TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &hToken))
    {
        LUID luid;
        if (LookupPrivilegeValue(NULL, szPrivilege, &luid))
        {
            BYTE t1[sizeof(TOKEN_PRIVILEGES) + sizeof(LUID_AND_ATTRIBUTES)];
            BYTE t2[sizeof(TOKEN_PRIVILEGES) + sizeof(LUID_AND_ATTRIBUTES)];
            DWORD cbTP = sizeof(TOKEN_PRIVILEGES) + sizeof (LUID_AND_ATTRIBUTES);

            PTOKEN_PRIVILEGES pTP = (PTOKEN_PRIVILEGES)t1;
            PTOKEN_PRIVILEGES pPrevTP = (PTOKEN_PRIVILEGES)t2;

            pTP->PrivilegeCount = 1;
            pTP->Privileges[0].Luid = luid;
            pTP->Privileges[0].Attributes = dwState;

            if (AdjustTokenPrivileges(hToken, FALSE, pTP, cbTP, pPrevTP, &cbTP))
                dwRtn = pPrevTP->Privileges[0].Attributes;
        }

        CloseHandle(hToken);
    }

    return dwRtn;
}

设置字体

hFont=CreateFont(16,0,0,0,0,0,0,0,0,0,0,0,0,L"Courier New");
SendMessage(hwndEdit, WM_SETFONT, (WPARAM)hFont, (LPARAM)FALSE);

线程创建窗口

RegisterClassEx(&wndclass);

    hwnd = CreateWindow(
                szAppName, szAppName,
                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);
    }
