Check the file exists

[jessiejane]

I have a filename with Example112409.txt file in the folder.

The date changes according to the current date.

I file is palced everyday in the folder. How would I check the exists without checking the date.

Like Startswith and endwith..

       Dim FileFound As Boolean = False
        For Each file As String In System.IO.Directory.GetFiles("SomeFilePath")
            If file.StartsWith("Example") AndAlso file.EndsWith(".txt") Then
                FileFound = True
                Exit For
            End If
        Next
        If FileFound Then MessageBox.Show("File Found")

That helps me.

How would I test whether that file is empty or not?

As the filename is Example112409.txt and I need to check with the startswith("example") and endswith(".txt") whether the file is empty or not?

Any help...

Here is an example. Run this code, then incorporate it into your code however you wish.

        Dim ofd As New OpenFileDialog
        ofd.ShowDialog()
        Dim fi As New System.IO.FileInfo(ofd.FileName)
        If fi.Length = 0 Then
            MessageBox.Show("File " & ofd.FileName & " is empty")
        Else
            MessageBox.Show("File " & ofd.FileName & " is " & fi.Length.ToString & " bytes long")
        End If
