VB.NET和FORMS（Form.Show，Form.Hide ......） [英] VB.NET and FORMS (Form.Show, Form.Hide ... )

问题描述

我正在从Vb6迁移到VB.Net。我有一种感觉这已经出现了

之前...


VS.Net MSDN文件似乎表明以下内容应该有效：


Form1.Show

Form1.Visible = True

Form1.Hide

Form1.Visible = False

加载（Form1）

卸载（Form1）或者关闭（Form1）


然而，如你所知，这些都不是工作。我还检查了一本关于将VB6转换为VB.Net的书，并且它似乎也说上面是

正确。所以我猜我的语法错了。更正将是值得赞赏的，特别是因为我已经把我的头发拉出来了，所以我开始低头发了......


谢谢

I''m moving from Vb6 to VB.Net. I have a feeling this has come up
before...

The VS.Net MSDN file seems to state that the following should work:

Form1.Show
Form1.Visible = True
Form1.Hide
Form1.Visible = False
Load (Form1)
Unload (Form1) or perhaps Close (Form1)

Yet, as you know, none of these work. I also checked a book on
converting VB6 to VB.Net, and it also seems to say that the above is
correct. So I''m guessing my syntax is wrong. Corrections will be
appreciated, particularly since I''ve been pulling my hair out doing
this and I''m starting to run low on hair...

Thanks

推荐答案

Dim f As New System.Windows.Forms.Form（）


f.lblDesc.Text ="你是否像这样实例化你的新表格？


f.Show（）或.. 。


f.showdialog（）用于模态形式


Me.Close（）来自形式内的模态或...


f.Close（）或......


f.Hide（）


f.dispose （）

Dim f As New System.Windows.Forms.Form()

f.lblDesc.Text = "Did you instantiate your new form like this?"

f.Show() or...

f.showdialog() for modal form

Me.Close() from within form for modal or...

f.Close() or...

f.Hide()

f.dispose()

Hi Genetic，

我猜你正试图做那些事情从另一个表格。在

这种情况​​下它< has>之前会再次出现（并且会再次!!）


VB6中的Form1可用于获取实例化的表单。 Form1.Visible是

实际Form的Visible属性。


VB.NET中的Form1是< class>表格的实例可以从中创建
。 Form1作为<对象>不再适用。 Form1.Visible失败，因为

它要求该类的Visible属性，并且该类没有

一个 - 它只能用于实例课程。


如果你想从另一个表格（或其他

班级）访问你的''Form1''，你需要引用那个

Form1的实例。这可以全局存储在一个模块中，也可以传递到另一个

表格/班级。


如果这个解释只是为了提出更多问题，请随便提出。 :-)


问候，

Fergus

Hi Genetic,

I''m guessing that you are trying to do those things from another Form. In
which case it <has> come up before and will again (and again!!)

Form1 in VB6 can be used to get at the instantiated Form. Form1.Visible is
the Visible property of the actual Form.

Form1 in VB.NET is the <class> from which instances of the form can
created. Form1 as an <object> no longer applies. Form1.Visible fails because
it is asking for the Visible property of the class, and the class doesn''t have
one - it is only availble to instances of the class.

If you want to access your ''Form1'' from a different Form, (or another
class, for that matter) you need to have a reference to the instance of that
Form1. This can be stored globally in a module or passed into the other
Form/class.

If this explanation only serves to raise more questions, ask away. :-)

Regards,
Fergus

也许你可以回答我的问题， Fergus？

不是意思，而是在某人的线索上，但它有点相关...


我建议

表格.Close（）或...

Form.Hide（）

Form.Dispose（）


Form.Close（ ）是我教过的方法，我使用的是，但是，我已经运行了几个代码示例（由人们编写的知识比知识要多得多）我已经使用了Hide（）> Dispose（）方法。

区别是什么？

Maybe you can answer a question for me, Fergus?
Not meaning to but in on someone elses thread, but its kinda related ...

I suggested
Form.Close() or ...
Form.Hide()
Form.Dispose()

Form.Close() is the method I have been taught and that I use, however, I
have run across several code samples (written by people a hell of a lot more
knowledge than me) that have used the Hide() > Dispose() method.
Whats the difference?
