I am using Visual Studio 2003 to develop a windows application in which I
allow the users to just press Enter, while the focus is on a textbox, in
order to perform a search. My problem is that sometimes Keypress event
stops being raised. I have found that I can reproduce this behavior by
performing a search, opening up another form, then trying to perform another
search. The second search will NEVER work.

How can I fix this problem?

Thanks,
Todd Sparks

我是使用Visual Studio 2003开发一个Windows应用程序，我允许用户只需按Enter键，同时焦点在文本框上，以便执行搜索。我的问题是，有时候Keypress事件会停止被提升。我发现我可以通过执行搜索，打开另一个表单，然后尝试执行另一个搜索来重现此行为。第二次搜索永远不会有效。
