.net - Visual basic 2010 检查表单加载时文件是否存在

Question

我希望我的 Visual Basic 应用程序运行一个带有进度条的闪屏，然后检查文件是否存在，但我遇到了一个问题，因为一旦我启动并且闪屏出现，文件检查器就会启动，但我希望它检查何时加载 form1 而不是启动画面。这是我的代码，我可以使用一个建议:

启动画面:

Public NotInheritable Class SplashScreen1

    'TODO: This form can easily be set as the splash screen for the application by going to the "Application" tab
    '  of the Project Designer ("Properties" under the "Project" menu).       

    Private Sub Splashscreen1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        Dim Dte As DateTime = DateTime.Now
        Label2.Text = FormatDateTime(Dte, DateFormat.LongDate)

        Timer1.Start()
        Timer2.Start()

    End Sub

    Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
        If ProgressBar1.Value = ProgressBar1.Maximum Then
            Form1.Show()
            Me.Close()
        End If

    End Sub

    Private Sub Timer2_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer2.Tick
        ProgressBar1.PerformStep()
    End Sub
End Class

表格 1:

Imports System.Net
Imports System.IO
Public Class Form1
    Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

        If My.Computer.FileSystem.FileExists(Application.StartupPath & "/read me.txt") Then
            MsgBox("file found")
        Else
            MsgBox("not found")
        End If

    End Sub
End Class

尝试将您的 Form1 代码从 Load 事件移动到 Shown 事件。在表单对用户可见之前运行加载，根据我的理解，这不是您想要的。
