控制多个Windows窗体 [英] Controling Multiple Windows Forms
问题描述
您好，
情况：
我的程序中的主窗体上有一个下拉列表。我有另一个表格
用于输入一个新项目，该项目将位于主要
表格的下拉列表中。当在第二个表单上单击添加项目按钮时，第二个
表单将关闭，但我还希望主表单重新绑定
下拉列表中的数据。
我不知道如何告诉主窗体重新绑定来自
form2_Closed事件的数据。
当我谷歌这个问题时，我得到了大量关于MDI的信息，但这不是我正在寻找的
情况。
我也查了一下form1.FromHandle（form2）但是我不知道如何获得一个表单的句柄，或者即使这是一个合适的方式来解决这个问题。 />
这个。
提前致谢，
- Paul
我可能需要改写这个...
我想访问我从父母那里创建的函数/>
表单（不是MDI父/子，但form1实例化一个新表单2）。
谢谢，
- Paul

我找到了解决这个问题的方法...在form1上，我调用我想要的逻辑
当form2或3或4关闭时发生form1_Activated发生。
仍然好奇如何做到这一点...
谢谢

问候Paul，
问题：Form2是否显示为模态？如果是这样，您可以使用
DialogResult来检查用户是否以可行的方式关闭对话框。
只需在使用Modal时添加Me.Hide（）关于OnClose
活动。
问候，
Paulo
Hello,
Situation:
I have a drop down list on a main form in my program. I have another form
for entering a new item that will reside in the drop down list of the main
form. When the Add item button is clicked on the second form, the second
form closes, but I also want the main form to rebind the data in the drop
down list.
I''m not sure how to tell the main form to rebind the data from the
form2_Closed event.
When I google this problem I get a ton of info on MDI, but that is not the
situation I''m looking for.
I''ve also looked into form1.FromHandle(form2) but I don''t know how to get
the handle of a form, or even if this is the appropriate way of going about
this.
Thanks in advance,
- Paul
I might need to rephrase this...
I would like to access functions I''ve created in a parent form from a child
form (not MDI parent/child, but form1 instantiates a new form2).
Thanks,
- Paul

I found a way around this problem... On form1, I call the logic I want to
occur when form2 or 3 or 4 closes when form1_Activated occurs.
Still curious about how to do this though...
Thanks

Greetings Paul,
Question: Is the Form2 shown as Modal? If so you can use the
DialogResult to check if the user closed the dialog in a workable way.
Just make suere that when using Modal, add Me.Hide() on the OnClose
event.
Regards,
Paulo
