    Access denied on adding another registry value

    I have originally created the SOFTWARE\\Testing key a few days ago and I just tried adding another value called TDate to this key and got an "Access denied" message when I execute the RegSetValueEx function. Does anybody know why I'm getting this "access denied" error message?

    EDIT: Found my mistake.. RegOpenKeyEx should be KEY_ALL_ACCESS NOT KEY_QUERY_VALUE. I guess I'm a little brain dead.

    DWORD lpdwDisp;
        HRESULT hRes;
        HKEY hKey;
        char szTDate[40] = {0};
        int iDatasize;
        char szTemp[120] = {0};
        char szRegistryKey[128] = "SOFTWARE\\Testing";
        if(RegOpenKeyEx (HKEY_CURRENT_USER, szRegistryKey, 0, KEY_QUERY_VALUE, &hKey) == ERROR_SUCCESS)
            iDatasize = sizeof ( szTDate);
            if(RegQueryValueEx(hKey, "TDate",
                NULL, NULL, (unsigned char *)& szTDate, (unsigned long *)&iDatasize) != ERROR_SUCCESS)
               printf("Query failed, create the value\n");
                strcpy(szTDate, "11082005");
                hRes = RegSetValueEx(hKey, "TDate", 0, REG_SZ,(LPBYTE)szTDate,(DWORD) strlen(szTDate)+1);
                 if( ERROR_SUCCESS != hRes)
                FormatMessage( FORMAT_MESSAGE_FROM_SYSTEM, NULL , hRes, 0, szTemp, 80 , NULL);
