    How to get combo box to show .exe files and not full path

    Apologies in advance I am very new to all this and working on my first project. I am trying to get the exe filename only to show and not the full path to it. for example doom.exe. Thanks in advance.

    This is what I have so far

    Code:
        Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
            Dim directory = "D:\Steam Library"
            Dim files() As System.IO.FileInfo
            Dim dirinfo As New System.IO.DirectoryInfo(directory)
            files = dirinfo.GetFiles("*.exe", IO.SearchOption.AllDirectories)
    
            For Each file In files
                cmbSelectGame.Items.Add(file)
    
    
            Next
    
        End Sub

    You are working with an object of type System.IO.FileInfo.

    Google search for that, and you will find the Microsoft documentation all about System.IO.FileInfo, and you should be able to find an appropriate Property that gives you the result you are looking for.

    It might seem rude for me to not just tell you the answer, but learning to find answers yourself will be much more valuable for you in the long run.

    Good luck.

    Also, don't add items in a loop like that. At the very least, add all items in one go with a single call to AddRange. Better still, bind the data by setting the DisplayMember, ValueMember and DataSource properties. That way, you can display the file names but, when the user selects one, get the full path from the SelectedValue. I'm not sure exactly what you want to do with the selection but, in most cases, you're going to need the full path of a file to do anything useful.

    Becoming familiar with Microsoft's documentation is one of the most important things any VB.NET developer can do. Good luck.

    If your TextBox is named PathTextBox,

    Code:
    Dim directory As String
    directory = PathTextBox.Text
    To populate PathTextBox.Text with the folder selected from a FolderBrowserDialog, take a look at the documentation below to find the appropriate property to use:

    https://docs.microsoft.com/en-us/dot...g?view=net-5.0

    Good luck.

    To get the directory that the picked in the FolderBrowserDialog, use the SelectedPath property: https://docs.microsoft.com/en-us/dot...g.selectedpath

    From here you can optionally set the TextBox's Text property: https://docs.microsoft.com/en-us/dot...s.textbox.text

    Finally, you can set the ComboBox's DataSource (documentation), DisplayMember (documentation), and ValueMember (documentation).

    With all of that being said, here is an example:
    Code:
    Using browseDialog = New FolderBrowserDialog()
        If (browseDialog.ShowDialog() = DialogResult.Ok) Then
            MyTextBox.Text = browseDialog.SelectedPath
    
    
            Dim selectedDirectory = New System.IO.DirectoryInfo(browseDialog.SelectedPath)
            With MyComboBox
                .DisplayMember = "Name"
                .ValueMember = "FullName"
                .DataSource = selectedDirectory.GetFiles("*.exe", IO.SearchOption.AllDirectories)
            End With
        End If
    End Using

                .ValueMember = "FullName"
                .DataSource = selectedDirectory.GetFiles("*.exe", IO.SearchOption.AllDirectories)
            End With
        End If
    End Using

    Thank you very much!

    This worked for when using the browse folder button however I want the user to be able to save the steam library path and be able to select the game from launch game combo box. When user loads back in they have to select browse again. Not sure if my idea is possible or where I would start. Ill add a photo of the project below to see how I have set it up. Thanks.

    You can create a setting: https://docs.microsoft.com/en-us/dot...ettings-object

    Once the user picks the folder using the dialog, you would add an extra step in the code that I provided where you persist the setting value: https://docs.microsoft.com/en-us/dot...-user-settings

    Finally in the form load event, you would get the setting value and basically run the same code that I already provided: https://docs.microsoft.com/en-us/dot...ation-settings
