同学你好~
hardly…when...是一个短语，意思是“几乎未来得及做完A这件事，紧接着就开始B这件事。”
He had hardly finished the article when the light went out.
他刚写完文，灯就熄了。
He had hardly had time to settle down when he sold the house.
他还未安顿下来，就卖掉了那所房子。

所以这里hardly的位置是对的。

另外，如果把hardly放于句首，主句要用倒装结构即谓语动词要提前。如：
Hardly had I finished eating when he came in.
我刚吃完他就进来了。
Hardly had she gone out when a student came to visit her.
她还没走出家门，就有一个学生来看望她。

祝同学学习进步~
