Add two strings together with the & operator. "hello" & "world"

Add two strings together with the & operator. "hello" & "world"

do you mean

IO.File.Copy(fullPath, IO.Path.ChangeExtension(fullPath & ".bak"))

hi i have this code but i get an error

Conversion from string "??" to type 'Long' is not valid.

Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
        Dim Filename As String
        Dim fs_con As System.IO.FileStream
        Dim CONHeader(CON_HEADER_LEN - 1) As Byte
        Dim fullPath As String
        Dim dirName As String
        Dim Backup As String = ".bak"
        
        If CheckBox1.Checked = True

            fullPath = Label4.Text
            dirName = Label5.Text
            Filename = IO.Path.GetFileName(fullPath)

            My.Computer.FileSystem.CopyFile(fullPath, dirName \ Filename & Backup, True)

        Else
            Return
        End If

My.Computer.FileSystem.CopyFile(fullPath, dirName \ Filename & Backup, True)

You can't divide strings.

Looks like you want something like:

My.Computer.FileSystem.CopyFile(fullPath, dirName & "\" & Filename & Backup, True)

That is, of course, assuming dirName and Filename are both variables you have defined.
