WinCE Forms的开幕式闭幕 [英] WinCE Forms Opening & Closing

问题描述

我在WinCE中的表单存在问题(很可能是一种理解).因此，由于我没有发布复杂的代码，因此我在一个简单的示例中重复了该问题；

I''m having a problem (most likely an understanding) with forms in WinCE. So as i don''t post complicated code i have replicated the problem in a simple example;

Public Class frmMain
Private Sub btnForm2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnForm2.Click
        Form2.Show()
    End Sub
End Class

Public Class Form2

    Private Sub btnClose_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnClose.Click
        Me.Hide()
    End Sub

    Private Sub Form2_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        'some code to add controls on the fly
    End Sub
End Class

这与按要求打开和关闭表单的按钮配合得很好，但是，我想更改Form 2事件(btnClose)，以便关闭表单，从而删除我即时添加的任何控件.如果我将事件更改为Me.Close()，则窗体将关闭，但无法使用Form 1中的按钮再次打开它，即:Form2.Show().(为什么我不知道).
我尝试过在隐藏之前在Form2上删除控件，但是在再次显示该窗体(Form2.Show)时，它不会转到Form2_Load，因此未添加新控件，因此我想关闭" Form2.
所以我的问题是，为什么Form2.Close阻止该窗体再次显示，并且解决方法是什么? -我敢肯定，这只是我对WinCE表格的理解不足.有什么想法吗?

This works well with the buttons opening and closing the forms as required however, i want to change the Form 2 event (btnClose) so that the form closes thus removing any controls i add on the fly. If i change the event to Me.Close() the form closes but i cannot open it again with the button in Form 1 ie: Form2.Show().(Why i don''t know).
I have tried removing the controls on Form2 just before the hide, but on showing the form again (Form2.Show) it doesn''t goto Form2_Load so new controls are not added thus my reason for wanting to ''Close'' Form2.
So my question is why does the Form2.Close stop the form from showing a second time and what is the workaround? - i''m sure this is just my poor understanding of WinCE forms. Any ideas?

推荐答案

好吧，我有一个解决方案-可行-尽管在我看来并不整洁；

基本上，将其公开后，只需调用"Load"子即可.

Ok i have one solution - which works - though is untidy in my view;

Basically just call the the ''Load'' Sub - after making it Public of course.

Public Class frmMain

    Private Sub btnForm2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnForm2.Click
        Form2.Show()
        Form2.Form2_Load()
    End Sub
End Class
 
Public Class Form2

    Private Sub btnClose_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnClose.Click
        Me.Hide()
        'for each ctr in me
        'delete controls
        'next
        frmMain.Show()
    End Sub

    Public Sub Form2_Load() Handles MyBase.Load
        'some code to add controls on the fly
    End Sub
End Class

还是很想听听建议等等...

Would still love to hear suggestions etc...
