The "hide_gui" key in the regedit , i want to know how does it works?

[ITboy_Lemon]

These days ,i read the source code of cocos2d-x . When i read the CCApplication class of win32 platform , in the function run of CCApplication ,there is a function :

static void PVRFrameEnableControlWindow(bool bEnable)
{
HKEY hKey = 0;

// Open PVRFrame control key, if not exist create it.
if(ERROR\_SUCCESS != RegCreateKeyExW(HKEY\_CURRENT\_USER,
    L"Software\\\\Imagination Technologies\\\\PVRVFRame\\\\STARTUP\\\\",
    0,
    0,
    REG\_OPTION\_NON\_VOLATILE,
    KEY\_ALL\_ACCESS,
    0,
    &hKey,
    NULL))
{
    return;
}

const WCHAR\* wszValue = L"hide\_gui";
const WCHAR\* wszNewData = (bEnable) ? L"NO" : L"YES";
WCHAR wszOldData\[256\] = {0};
DWORD   dwSize = sizeof(wszOldData);
LSTATUS status = RegQueryValueExW(hKey, wszValue, 0, NULL, (LPBYTE)wszOldData, &dwSize);
if (ERROR\_FILE\_NOT\_FOUND == status              // the key not exist
    || (ERROR\_SUCCESS == status                 // or the hide\_gui value is exist
    && 0 != wcscmp(wszNewData, wszOldData)))    // but new data and old data not equal
{
    dwSize = sizeof(WCHAR) \* (wcslen(wszNewData) + 1);
    RegSetValueEx(hKey, wszValue, 0, REG\_SZ, (const BYTE \*)wszNewData, dwSize);
}

RegCloseKey(hKey);

}

i do not understand the key value "hide_gui" .What can it do to effect my app ? I am a new learner in C++ and i am not a english speaker , so if you do not understand my meaning ,i am very sorry for that .

You need to contact Imagination Technologies about this, it's their software. However, the code above sets its value to "NO" or "YES", according to whether bEnable is true or not.

Use the best guess
