Question

I want get value 1 in all line for get path string, and programmatically add cover to flowlayoutpanel.

in Resource/Game List.ini (from drag n drop)

Apex Legends,Resource/Cover/Apex Legends.jpg,Resource/Game Info/Apex Legends.txt
Fortnite,Resource/Cover/Fortnite.jpg,Resource/Game Info/Fortnite.txt
PUBG,Resource/Cover/PUBG.jpg,Resource/Game Info/PUBG.txt

here my code :

Private Sub LabelSetting_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles LabelSetting.Click
        FlpAddItem.Controls.Clear()

        'I am confused in this part to get value 1 in all line for get path string
        'Directory.GetFiles(Path) will be replace with streamreader from lines(i) value 1

        Dim Path = '???
        Dim ImageX As Image = Nothing
        Dim x As Int32 = Directory.GetFiles(Path).Count - 1
        Dim Img(x) As PictureBox
        Dim ImgText(x) As Label
        Dim ImgPanel As Panel

        For i = 0 To Directory.GetFiles(Path).Count - 1
            ImgPanel = New Panel
            With ImgPanel
                .Width = 96
                .Height = 136
                .BackColor = Color.Transparent
            End With

            FlpAddItem.Controls.Add(ImgPanel) 'Add panel to the flowlayoutpanel

            ImgText(i) = New Label
            With ImgText(i)
                .Name = Directory.GetFiles(Path)(i).Replace(Path, "").Replace(".jpg", "").Replace(".png", "")
                .FlatStyle = FlatStyle.Popup
                .Width = 116
                .Height = 40
                .Padding = New Padding(0, 3, 0, 0)
                .TextAlign = ContentAlignment.TopCenter
                .Dock = DockStyle.Bottom
                .BackColor = Color.Transparent
                .ForeColor = Color.Black
            End With

            Img(i) = New PictureBox
            With Img(i)
                .Width = 96
                .Height = 96
                .Padding = New Padding(20, 20, 20, 20)
                .BackColor = Color.Transparent
                .BorderStyle = BorderStyle.FixedSingle
                .SizeMode = PictureBoxSizeMode.StretchImage
            End With
            ImgPanel.Controls.Add(Img(i)) 'Add the picturebox to the panel

            ImageX = Image.FromFile(Directory.GetFiles(Path)(i), True)
            Img(i).Image = Image.FromFile(Directory.GetFiles(Path)(i))
            ImgText(i).Text = Directory.GetFiles(Path)(i)
            ImgPanel.Controls.Add(ImgText(i))
        Next
End Sub

Answer 1

I suggest creating a class for the game name and path information

Public Class GamePath
    Public Property GameName As String
    Property Path As String

    Public Overrides Function ToString() As String
        Return GameName
    End Function
End Class

I have overridden ToString, so that the game name will automatically be displayed in a ListBox.

When loading the form, I read this information from the INI-file and set it as data source of a listbox, where you will be able to select a game.

Private Sub Form_Load(sender As Object, e As EventArgs) Handles MyBase.Load
    Dim games =
        From line In File.ReadLines(IniFilePath)
        Let parts = line.Split(","c)
        Select New GamePath With {.GameName = parts(0), .Path = parts(1)}
    GameListBox.DataSource = games.ToList()
    GameListBox.SelectedIndex = 0 'Select first game
End Sub

Note that it is easier to use File.ReadLines than a StreamReader. You will have to add Imports System.IO to the top of the code. Then we use the LINQ syntax to split each line at the comma and to create the game path information.

The user selects a game in the ListBox and then clicks a button. You can get the file path information from the ListBox like this:

Dim gamePath As GamePath = DirectCast(GameListBox.SelectedItem, GamePath)

Then read the files only once and assign the result to a variable

Dim files As String() = Directory.GetFiles(gamePath.Path)

Get the file count

Dim fileCount As Integer = files.Count

The whole Click method:

Private Sub StartGameButton_Click(sender As Object, e As EventArgs) Handles StartGameButton.Click
    FlpAddItem.Controls.Clear()

    Dim gamePath As GamePath = DirectCast(GameListBox.SelectedItem, GamePath)
    Dim files As String() = Directory.GetFiles(gamePath.Path)
    Dim fileCount As Integer = files.Count

    Dim ImageX As Image = Nothing
    Dim Img(fileCount) As PictureBox
    Dim ImgText(fileCount) As Label
    Dim ImgPanel As Panel

    For i = 0 To fileCount - 1
        Dim filePath = files(i)
        ImgPanel = New Panel
        With ImgPanel
            .Width = 96
            .Height = 136
            .BackColor = Color.Transparent
        End With

        FlpAddItem.Controls.Add(ImgPanel) 'Add panel to the flowlayoutpanel

        ImgText(i) = New Label
        With ImgText(i)
            .Name = System.IO.Path.GetFileNameWithoutExtension(filePath)
            .FlatStyle = FlatStyle.Popup
            .Width = 116
            .Height = 40
            .Padding = New Padding(0, 3, 0, 0)
            .TextAlign = ContentAlignment.TopCenter
            .Dock = DockStyle.Bottom
            .BackColor = Color.Transparent
            .ForeColor = Color.Black
        End With

        Img(i) = New PictureBox
        With Img(i)
            .Width = 96
            .Height = 96
            .Padding = New Padding(20, 20, 20, 20)
            .BackColor = Color.Transparent
            .BorderStyle = BorderStyle.FixedSingle
            .SizeMode = PictureBoxSizeMode.StretchImage
        End With
        ImgPanel.Controls.Add(Img(i)) 'Add the picturebox to the panel

        ImageX = Image.FromFile(filePath, True)
        Img(i).Image = Image.FromFile(filePath)
        ImgText(i).Text = filePath
        ImgPanel.Controls.Add(ImgText(i))
    Next
End Sub

Some details:

In the For-loop you can get the path of an image file with

Dim filePath = files(i)

You can get the name of the image with

.Name = System.IO.Path.GetFileNameWithoutExtension(filePath)

This automatically removes the directory name and the extension.

Later on, you don't call Directory.GetFiles again:

ImageX = Image.FromFile(filePath, True)
Img(i).Image = Image.FromFile(filePath)
ImgText(i).Text = filePath

---

If you only want to read the file paths into a list, you could write

Dim games =
    (From line In File.ReadLines(IniFilePath)
     Select line.Split(","c)(1)).ToList()
