在一个大型的旧应用程序中,我必须修正,我有两种形式,如图像(一个Notpad示例)中的两种形式。
""https://i.sstatic.net/pGC2U.jpg" alt="此处输入图像描述"/ >
当我离开(用鼠标指针)我的小区域时,该表将“消失”,有些像点击大窗体并激活它。
但我没有点击 X, X 标题也没有活动, 但是小Y 形式会向后退, 不再可见 。
如何追踪问题?

尝试覆盖 < a href=> "" "http://msdn.microsoft.com/ en-us/library/ system. windows.forms.control. onvisible changed.aspx" rel = “nofollow” > On VeabilableChanged of Form Y, 并设置此上的断点。 在调试时复制情况并检查属性表。 可见于错误, 检查时检查比调用堆 。
据我所知,这是整个系统的事情;我认为它叫做“强势a href=”“http://technet.microsoft.com/en-us/library/cc957204.aspx” rel=“不跟随”>活动窗口跟踪。
可能想试着弄坏它
进行多次测试后,我发现了问题: " 强" 代码Y < /code < /code > / " 强 " 窗体是 deactivate ,由 " 强 " X < /code < /code < / defense > > 表示,因为在 MouseMove 事件上, X 产生了关于(X) 窗体内特定控件的焦点()...
感谢大家的帮助!
(PS.
您可以将 Y 顶部属性设置为 True 。 这样它就不会在 X 后面消失 。 (前提是 X 的最大属性不真实 。)
