    Angry Writting to registry failling

    Code:
    bool WriteRegStr(HKEY hKey, const char *lpszSubKey, const char *lpszValueName, const char *lpData)
    {
        HKEY hkey;
    	if (RegOpenKeyEx(hKey, lpszSubKey, 0, KEY_ALL_ACCESS, &hkey) != ERROR_SUCCESS) return false;
    	{
    		if (RegSetValueEx(hKey, lpszValueName, 0, REG_SZ, LPBYTE(lpData), lstrlen(lpData)+1) != ERROR_SUCCESS) return false;
    		RegCloseKey(hkey);
    		return true;
    	}
    	return false;
    }
    WriteRegStr(HKEY_CURRENT_USER, "Software\\Joel", "temp", "boom");

    I'm attempting to update temp but it doesn't do the job, any ideas?

    Wakka wakka. Your local HKEY variable is used instead of the argument you passed. Probably unintended.

    HKEY hKey
    HKEY hkey;
    RegOpenKeyEx(hKey,

    good one is used.the argument has a uppercase, same for the parameter passed in RegOpenKeyEx.Very confusing when having two such variables.
