这么多,都写了这个话题,但我的问题是不是我可以在previous线程发现一个有点不同。我可以通过一个对象到第二个形式,但它不是在第二形式的所有字幕可用。我需要它。在FRM2作品的第一个code座和动物名表演,但第二个code座(cmdSave)不工作 - 它说,动物没有宣布。谁能告诉我什么,我需要改变,使下面工作的最后code座(cmdSave)?
表格1 code:
暗淡FRM2作为新FRM2(动物)
Frm2.Show()
Me.Close()
FRM2 code:
的Public Sub New(BYVAL动物为对象)
的InitializeComponent()
Msgbox.show(animal.animalName)
完子
私人小组cmdSave
Msgbox.show(animal.animalName)
完子
解决方案
我想你只需要在 FRM2
A(私有)成员牵着你通过动物对象,以便您能够访问它 cmdSave
。
请参阅下面的code,其中 m_Animal
是私有成员。
FRM2 code:的
公共类窗体2
...
私人m_Animal为对象
公共子新(BYVAL动物为对象)
的InitializeComponent()
m_Animal =动物
Msgbox.show(animal.animalName)
完子
私人小组cmdSave
Msgbox.show(m_Animal.animalName)
完子

So much as been written about this topic but my problem is a little different than what I can find in the previous threads. I can pass an object over to a second form but it is not available in all subs of the second form. I need it to be. The first code block in frm2 works and the animal name shows but the second code block (cmdSave) does not work - it says animal not declared. Can someone tell me what I need to change to make the last code block (cmdSave) below work?
Form 1 code:
Dim frm2 As New frm2(animal)
Frm2.Show()
Me.Close()
frm2 code:
Public Sub New(ByVal animal As Object)
InitializeComponent()
Msgbox.show(animal.animalName)
End sub
Private sub cmdSave
Msgbox.show(animal.animalName)
End sub
解决方案
I think you just need a (private) member in frm2
holding your passed animal object so that you are able to access it in cmdSave
.
See the following code, where m_Animal
is the private member.
frm2 code:
Public Class Form2
...
Private m_Animal as Object
Public Sub New(ByVal animal As Object)
InitializeComponent()
m_Animal = animal
Msgbox.show(animal.animalName)
End sub
Private sub cmdSave
Msgbox.show(m_Animal.animalName)
End sub
...
End Class
