I''m writing a vb.net forms application. I collect some information
in a listbox from the main form. Then I want to use that listbox
arraylist in another form on the same application. What''s the
best way to get that information or listbox object to the next form.

After a submit button click I want to go to
newform.DefInstance.ShowDialog() and I want the listbox to be
available, in scope.

Much Thanks;

推荐答案

你可以使用一个属性：
$ b $例如，在你要显示项目的第二个表单上，你添加了一个

属性：


公共属性myItems（）如ListBox.ObjectCollection

获取

返回ListBox1.Items

结束获取

设置（ByVal值为ListBox.ObjectCollection）

ListBox1.Items.AddRange（超值）

结束集

结束物业


和第一张表格在那里你打电话给第二个表格你会做一些像这样的事情：
这个：


Dim frm2 As New Form2

frm2.myItems = ListBox1 .Items

frm2.Show（）

Hi, you can use a property for that:
for example on the second form where you want to show the items, you add a
property:

Public Property myItems() As ListBox.ObjectCollection
Get
Return ListBox1.Items
End Get
Set(ByVal Value As ListBox.ObjectCollection)
ListBox1.Items.AddRange(Value)
End Set
End Property

and on the first form where you call the second form you do something like
this:

Dim frm2 As New Form2
frm2.myItems = ListBox1.Items
frm2.Show()

Seque，


您一次只能激活一个表单。

传递给showdialog表单通常是以


\\\

dim frm2 as new form2

dim frm2.HisArraylist = myarraylist

frm2.showdialog

frm2.dispose

///


我希望这会有所帮助，

Cor

Seque,

You have only one form active in a time.
Passing to a showdialog form is commonly done as

\\\
dim frm2 as new form2
dim frm2.HisArraylist = myarraylist
frm2.showdialog
frm2.dispose
///

I hope this helps,

Cor

我最终使用了这个解决方案。


谢谢。

问候;
