[RESOLVED] [2008] Getting a list of files with certain file types

[Louix]

Hi!
How do I get a list of files with a certain extension in a directory and return that list in a combobox?
e.g
Say I want to find all the text files in the "C:\" directory and return their names in a combobox, how would I go about doing it?

Any help is much appreciated.

Louix.

        Dim di As New System.IO.DirectoryInfo("C:\")
        Dim fi() As System.IO.FileInfo
        fi = di.GetFiles("*.txt")
        For ct As Integer = 0 To fi.Length - 1
            Debug.WriteLine(fi(ct).FullName)
        Next

Use the GetFiles function.

Option Explicit On
Option Strict On

Public Class Form1

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim xlFiles() As String
        xlFiles = System.IO.Directory.GetFiles("C:\Users\UserName\Documents", "*.xls", IO.SearchOption.TopDirectoryOnly)
        ComboBox1.Items.AddRange(xlFiles)
    End Sub

End Class

If you want only the file names, rather than the full paths, displayed in the ComboBox you'd modify what's already been posted:

myComboBox.DisplayMember = "Name"
myComboBox.ValueMember = "FullName"
myComboBox.DataSource = (New IO.DirectoryInfo("folder path here")).GetFiles("*.txt")

By binding an array of FileInfo objects to the control you have access to the file name only as well as the full path. Setting the DisplayMember to "Name" will display just the file names in the control, while setting the ValueMember to "FullName" will return the full path of the selected file from the control's SelectedValue property.
