winform窗体关闭的时候..线程跟db有没有自动关闭?我搞了50个线程..每个线程都有db执行我现在要弄个按钮.点下去所有线程跟db全部关闭但是我DB都是在方法里面声明的,,所以我在想..winform窗体关闭的时候..线程跟db有没有自动关闭?如果有我就点了按钮然后调用窗体关闭事件可以不?怎么搞?急!!答案1------其他回答（60分）---------如果你想比较灵活的控制建议不要在方法里面声明，而是要放在类的成员变量里面声明然后，专门开方法去init 或是 destroy查看和“c/c++”有关的所有文章

I should be able to do something like:
browserControl.JSCall("myFunction('Dave','Smith');");
...and in the web code:
function myFunction(firstName, lastName) {
$("#mydiv").text(firstName + ' ' + lastName);
Thanks - Dave
解决方案 You can do this using Navigate:
browserControl.Navigate("javascript:void(myFunction('Dave','Smith'))");
Note, I find that the code isn't actually run until the application event loop executes. If that's a problem for you, you might be able to follow the Navigate call with
Application.DoEvents();
Make sure you consider the .

这些问题说明了一切。我把一切都连接起来，并知道如何从浏览器的HTML邮件发送到C＃，而不是其他方式
我应该可以做一些事情，如：
browserControl.JSCall（“myFunction的（'大卫'，'史密斯'）;”）;
...并在网页代码：
函数myFunction的（名字，姓氏）{ $（“＃mydiv”）。文本（名字+''+的lastName）; }
谢谢 - 戴夫
解决方案 您可以做到这一点使用导航：
browserControl.Navigate（“JavaScript的：无效（myFunction的（'大卫'，'史密斯'））”）;
请注意，我发现这个代码是不实际运行，直到应用程序事件循环执行。如果这是你一个问题，你也许可以跟随导航与电话
Application.DoEvents（）;
请确保你考虑的的危险。
