Dim ImagePath As String = "E:\Net Project\Voting\FJCCI\FJCCI\" & Val(TxtReceiptNo.Text) & ".jpg"

                Dim FileInfo As New FileInfo(ImagePath)
                MessageBox.Show(FileInfo.Extension)

                Dim extension As String = Path.GetExtension(ImagePath)

                Console.WriteLine("GetExtension('{0}') returns '{1}'", ImagePath, extension)

                Console.WriteLine(extension)
                ' Console.WriteLine(".txt" = extension)

Try:

Dim folder As New DirectoryInfo("E:\Net Project\Voting\FJCCI\FJCCI\")
Dim file As FileInfo = folder.EnumerateFiles(TxtReceiptNo.Text + ".*").FirstOrDefault()
If file Is Nothing Then
MessageBox.Show("The specified file does not exist.")
Else
MessageBox.Show(file.Extension)
End If
