昏暗的测试作为新的形式1 [英] dim test as new form1
问题描述
大家好，
i有一个设定形式（form4）
此表单从mdi父窗体打开1
我想要做的是，当我在form4中进行更改（调整设置），然后在mdi父form1中的一个
列表视图重新启动，这就是我所做的。
公共类Form4
继承System.Windows.Forms.Form
Dim windowmain As New Form1（）
Private Sub Button1_Click（ByVal sender As System.Object，ByVal e As
System.EventArgs）处理Button1.Click
Next inti
otherwindow.listsetup（）
Me.close
End Sub
现在的问题是，当我尝试打开form4时，我得到了所有
组件的错误
对象引用未设置为对象的实例。
form1，我认为因为我将表单声明为新表单。
我能做什么与form1沟通
问候，
Maarten

推荐答案
Maarten，
在我看来，简单的方法就是你可以永远地从你的工作中获得支付
me.parentform .mdichildren收藏
在你的form4中有这样的东西，这是一个非常改变的文本在这个
的消息所以看看错别字
\\ \\\\
For Each frm As Form In Me.ParentForm.MdiChildren
如果frm.Name =" frm1"然后
DirectCast（frm，form1）。随便= text.Text
退出Sub
结束如果
下一步

我希望这有帮助吗？

大家好，
Maarten,
The simple way is in my opinion that you can work forever from your
me.parentform.mdichildren collection
Something as this in your form4 which is very much changed text in this
message so watch typos
\\\
For Each frm As Form In Me.ParentForm.MdiChildren
If frm.Name = "frm1" Then
DirectCast(frm, form1).Whatever = text.Text
Exit Sub
End If
Next

I hope this helps?

感谢您的回复
但是我通过AS得到错误（语法错误）。 in For Each frm As Form in
Me.ParentForm.MdiChildren。
但我觉得它更简单，如果我从中得到数据
如果关注parrentform会形成一个孩子吗？
但我将如何做到这一点？
我们欢迎提出建议。
亲切的问候Maarten。

Maarten，
在我看来，简单的方法是你可以永远地从你的
me.parentform.mdichildren集合中继续工作
在你的form4中这样的东西非常多更改了此消息中的文字，以便观看错别字
\\\
每个frm作为表单在Me.ParentForm.MdiChildren
如果frm.Name =" frm1"然后
DirectCast（frm，form1）。随便= text.Text
退出Sub
结束如果

我假设您使用的是VB.NET 2002：
\\\
Dim f As Form
For Each f In Me.MdiChildren
