    Registry Checker

    This boolean always returns false :S
    Anyone have any suggestions as to why?

    Code:
    bool keyExists()
    {
    	HKEY hKey;
    	DWORD lRv = RegOpenKeyEx(HKEY_CURRENT_USER,(LPCTSTR)"Software\\Microsoft\\Windows\\CurrentVersion\\Policies\\Explorer", 0, KEY_READ, &hKey);
    	if (lRv == ERROR_SUCCESS)
    		return true;
    	else
    		return false;
    	RegCloseKey(hKey);
    }
    And I'm checking it's return value like so:
    Code:
    if (keyExists())
    	printf("Found");
    else
    	printf("Not Found");

    Reading the documentation, we see this:

    If the function fails, the return value is a nonzero error code defined in Winerror.h. You can use the FormatMessage function with the FORMAT_MESSAGE_FROM_SYSTEM flag to get a generic description of the error.
    Have you tried that?

    And where you've put this
    Code:
    RegCloseKey(hKey);
    it's utterly pointless as you've returned from the function. I'm surprised you don't get at least a warning for unreachable code on that.
