如何在visual basic 2008中使用线程来优化线程 [英] How to use threading for optimise threading in visual basic 2008

问题描述

我有一小段代码从指定目录加载图像并使用它们动态创建image-checkbox并添加到FlowLayoutPanel。现在我想使用带螺纹来更快地加载图像。我是新手，不知道如何使用线程。有人可以帮帮我吗？



我的代码：

I have a small piece of code to load images from specified directory and create image-checkbox dynamically with them and add to a FlowLayoutPanel. Now I want to useelp threading to load images faster. I am a newbie and don't know how to use threading. Can anybody help me?

My Code:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim dlg As New FolderBrowserDialog
        If dlg.ShowDialog = DialogResult.OK Then
            TextBox1.Text = dlg.SelectedPath
            For Each item As String In Directory.GetFiles(TextBox1.Text, "*.jpg")
                Dim checkBox As New CheckBox
                Dim original As Image = Image.FromFile(item)
                Dim resized As Image = ResizeImage(original, New Size(78, 78))
                original.Dispose()
                checkBox.Size = New Size(117, 109)
                checkBox.Text = (Path.GetFileName(item))
                checkBox.Image = resized
                checkBox.BackColor = Color.Gray
                checkBox.ForeColor = Color.White
                checkBox.TextAlign = ContentAlignment.BottomCenter
                AddHandler checkBox.CheckedChanged, AddressOf myhandler2
                FlowLayoutPanel1.Controls.Add(checkBox)
            Next
        End If
    End Sub

我尝试过：



我不尝试任何事情。因为我对如何做到这一点一无所知。

What I have tried:

I do not try anything. As I don't have any idea on how to do that.
