I am using vb form. I was wondering if there is an event (or way ) that check if when the user click the close form button? If yes, can you also cancel the form from closing ?

推荐答案

是的，有一种方法，奇怪的是，它被称为FormClosing事件，你只需要拦截它。 FormClosing事件 [ ^ ]对如何使用它有很好的参考。 Yes, there is a way, oddly enough, its called the FormClosing event, and you just need to intercept it. FormClosing Event[^] on MSDN has a good reference for how to use it.

是的，是的。 处理Form.FormClosing事件，它将会给你一个FormClosingEventArgs作为参数。 这包含一个属性 CloseReason [ ^ ]它会为您提供尽可能多的信息，并且还有取消 [ ^ ]您可以设置为 True 如果你想阻止它关闭。 注意：如果你总是取消表格关闭，你会严重惹恼你的用户！为他们提供一些机制...... Yes, and yes. Handle the Form.FormClosing event, and it will give you a FormClosingEventArgs as a parameter. This contains a property CloseReason[^] which gives you as much info as you are going to get, and also has a Cancel[^] property that you can set to True if you want to prevent it closing. Note: if you always cancel the Form Close, you will seriously annoy your users! Provide some mechanism for them to get out...
