推荐答案

请确保您未通过代码处理frmSChild表单.

Ensure that you are not disposing off the frmSChild form via your code.

一个猜测，您没有正确遵循文章中的说明.

请勿在问题与解答"下发布此内容答案-如果您从某篇文章中获取了代码，那么该文章的底部会出现一个新消息"按钮，该按钮会导致向作者发送电子邮件.然后会通知他们您希望与他们交谈.
将其发布到此处依赖于他们的"drop by"并意识到它是针对他们的.

At a guess, you didn''t follow the instructions in the article correctly.

Don''t post this under Questions & Answers - if you got the code from an article, then there is a "new message" button at the bottom of that article, which causes an email to be sent to the author. They are then alerted that you wish to speak to them.
Posting this here relies on them "dropping by" and realising it is for them.
