我的朋友和我已经编写了这段代码来修改注册表,但是当我们运行它时,它似乎没有将值写入注册表,只检查它们是否设置正确。 如果他们在程序之前设置正确,则不会给出任何弹出窗口。 但是如果注册表项不匹配,那么该程序应该写出正确的注册表值,但它现在没有,我们不知道为什么它不能正常工作......
这是完整的代码:

HKEY ErrMode;
LONG res = RegOpenKeyEx(HKEY_LOCAL_MACHINE, "SYSTEM\\ControlSet001\\Control\\Windows", 0, KEY_READ | KEY_WRITE, &ErrMode);
if (res == ERROR_SUCCESS)
{
DWORD ErrorMode;
DWORD DRlen = sizeof(DWORD);
DWORD SUlen = sizeof(DWORD);
if (RegQueryValueEx(ErrMode, "ErrorMode", 0, NULL, (LPBYTE)&ErrorMode, &DRlen) == ERROR_SUCCESS)
{
if (ErrorMode != 2) // any of errormode is non-2
{
if (MessageBox(NULL, "Windows Error Reporting is still turned on.\r\nThis program may not work correctly with reporting turned on. Shall I disable it?\r\nNote:The readme explains how you can disable and enable Error Reporting under Windows)","Windows Error Reporting:",
MB_YESNO | MB_ICONQUESTION | MB_APPLMODAL) == IDYES)
{
ErrorMode = 2; // change local
DRlen = sizeof(DWORD);
SUlen = sizeof(DWORD);
if (RegSetValueEx(ErrMode,"ErrorMode",2, REG_DWORD, (LPBYTE)&ErrorMode, DRlen) != ERROR_SUCCESS)
{
char* buff = new char[1024];
FormatMessage(FORMAT_MESSAGE_FROM_SYSTEM,0,res,0,buff,1024,0);

delete[] buff;
ok = false;
}
}

ok = false;
}
}

HKEY_LOCAL_MACHINE
是系统位置;作为“普通”用户,您无权在那里写作。您需要管理员权限。

尝试将您调用Reserved
至RegSetValueEx()
的{{1}}参数设置为instructed in MSDN,而不是您在代码中使用的0
