显示模态，然后再次显示 [英] Show Modal, then Again
问题描述
Hello Everyone，
VB.Net 2003
我想从Form1以模态方式打开一个表单（Form2），然后从Form2
以模态显示Form3。似乎一旦我打开第三个表格然后
关闭它，第二个表格也会关闭。如何防止发生这种情况？
我想我必须创建一个模态助手。这将以模态方式打开
所需的表格，等待它关闭，然后将结果返回给
来电者。我是否走在正确的轨道上？
TIA
Hello Everyone,
VB.Net 2003
I would like to open a form (Form2) modally from Form1, then from Form2
display Form3 modally. It seems that once I open that third form and then
close it, the second form also closes. How can I prevent that from
happening?
I am thinking that I have to create a "Modal Helper" that will open the
desired form modally, wait for it to close and then return a result to the
caller. Am I on the right track?
TIA

您是否设置了Button的Dialogresult属性，其中显示了''Click事件
Form3？

Did you set the Dialogresult property of the Button in which''s Click event
you show Form3?

我手动设置每个表单的对话结果;我没看到
如何设置值（默认为Cancel）会终止上一个表单的模态
对话框。
Private Sub cmdOk_Click（ByVal sender As System.Object，ByVal e As
System.EventArgs）处理cmdOk.Click
Me.DialogResult = DialogResult.OK
Me.Close（）
End Sub
Private Sub cmdCancel_Click（ByVal sender As System.Object，ByVal e As
System.EventArgs）处理cmdCancel.Click
Me.DialogResult = DialogResult.Cancel
Me.Close（）
End Sub

I manually set the dialogresult of each form, however; I fail to see how
setting the value (which is Cancel by default) would terminated the modal
dialog of the previous form.
Private Sub cmdOk_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles cmdOk.Click
Me.DialogResult = DialogResult.OK
Me.Close()
End Sub
Private Sub cmdCancel_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles cmdCancel.Click
Me.DialogResult = DialogResult.Cancel
Me.Close()
End Sub

>来自DialogResult的文档（强调我的）：
表单的对话结果是当表单显示为模式对话框时从表单
返回的值。
注意这一部分：
如果表单显示为对话框，则使用DialogResult枚举中的
值设置此属性将设置对话框的值
$ b表单的$ b结果，隐藏模态对话框，并将控制权返回到
调用表单。
>From the docs for DialogResult (emphasis mine):
The dialog result of a form is the value that is returned from the form
when it is displayed as a modal dialog.
Note this part:
If the form is displayed as a dialog box, setting this property with a
value from the DialogResult enumeration sets the value of the dialog
result for the form, hides the modal dialog, and returns control to the
calling form.
