问：OnLoad [英] Q: OnLoad

问题描述

如果我想要一个来自显示的OpenFileDialog

，那么有人能告诉我我应该使用的事件吗？我尝试将它放在OnLoad

表格中，但这意味着在OpenFileDialog

关闭之前表格并没有完全显示。


非常感谢提前


Geoff

Can anybody tell me the event I should use if I want a OpenFileDialog to
open as soon as a from has displayed? I tried putting it in the forms OnLoad
but this means that the form isn''t fully displayed until the OpenFileDialog
is shutdown.

Many thanks in advance

Geoff

推荐答案

Geoff，


在调用openfiledialog的ShowDialog方法之前尝试放置Me.Show。

Geoff,

Try putting Me.Show before calling the openfiledialog''s ShowDialog method.

Geoff，

您是否考虑过使用Activate活动？


类似于：


受保护的覆盖Sub OnLoad（ByVal e As System.EventArgs）

MyBase.OnLoad（e）

AddHandler Me.Activated，AddressOf MainForm_InitialOpen

End Sub


Private Sub MainForm_InitialOpen（ByVal sender As Object，ByVal e As

System.EventArgs）

RemoveHandler Me.Activated，AddressOf MainForm_InitialOpen

Dim对话框As New OpenFileDialog

dialog.ShowDialog（我）

结束子


AddHandler& RemoveHandler确保MainForm_InitialOpen仅被调用一次。


如果我有许多需要InitialOpen的表单。事件我会

考虑将上面的代码放在一个引发InitialOpen

事件的基类中，当第一个Activated事件被调用时......


我的另一个想法是Application.Idle事件，你也只允许

被调用一次。


希望这有助于

Jay

Geoff,
Have you considered using the Activate event?

Something like:

Protected Overrides Sub OnLoad(ByVal e As System.EventArgs)
MyBase.OnLoad(e)
AddHandler Me.Activated, AddressOf MainForm_InitialOpen
End Sub

Private Sub MainForm_InitialOpen(ByVal sender As Object, ByVal e As
System.EventArgs)
RemoveHandler Me.Activated, AddressOf MainForm_InitialOpen
Dim dialog As New OpenFileDialog
dialog.ShowDialog(Me)
End Sub

The AddHandler & RemoveHandler ensure that MainForm_InitialOpen is only
called once.

If I had a number of forms that need the "InitialOpen" event I would
consider putting the above code in a base class that raises an InitialOpen
event, when the first Activated event is called...

My other thought was the Application.Idle event, that you also only allow to
be called once.

Hope this helps
Jay
