Hi all,

I have 2 textboxes. First one for source file, second one for destination folder.

When I click source button, an openfiledialog appear for me to select file. And after I click open button, it should put the multiselect file into first textbox. Then I click select destination folder button and it will open folderbrowserdialog to select which dest. folder..but it failed to copy since it appear 1 path in the first textbox. Here are my code, please someone tell me the right code..
Private Sub btnSelectFile_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSelectFile.Click
        Dim strFileNameAndPath As String = SelectFileSource()
        txtSource.Text = strFileNameAndPath
    End Sub
Private Sub btnSelectFolder_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSelectFolder.Click
    Dim strFolderPath As String = SelectFolderDest()
    txtDest.Text = strFolderPath
End Sub
Private Sub btnStartCopy_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnStartCopy.Click
    For Each filePath As String In txtSource.Text
        My.Computer.FileSystem.CopyFile(txtSource.Text, txtDest.Text)
End Sub</pre>
#Region "PATH FILE"
    Private Function SelectFileSource() As String
        Dim strFileName = ""
        Dim fileDialogBox As New OpenFileDialog()
        fileDialogBox.Title = "Select file to copy | " & GlobVars.strFileDesc
        fileDialogBox.Multiselect = True
        fileDialogBox.CheckPathExists = True
        fileDialogBox.Filter = "All Files (*.*)|*.*"
        fileDialogBox.InitialDirectory = Environment.GetFolderPath(Environment.SpecialFolder.MyComputer)
    If (fileDialogBox.ShowDialog() = DialogResult.OK) Then
        strFileName = fileDialogBox.FileName
    End If
    Return strFileName
End Function
Private Function SelectFolderDest() As String
    Dim strFolderPath = &quot;&quot;
    Dim MyFolderBrowser As New System.Windows.Forms.FolderBrowserDialog
    MyFolderBrowser.Description = &quot;Select destination folder for &quot; &amp; GlobVars.strFileDesc
    MyFolderBrowser.RootFolder = Environment.SpecialFolder.MyComputer
    MyFolderBrowser.ShowNewFolderButton = True
    Dim dlgResult As DialogResult = MyFolderBrowser.ShowDialog()
    If dlgResult = Windows.Forms.DialogResult.OK Then
        strFolderPath = MyFolderBrowser.SelectedPath
    End If
    Return strFolderPath
End Function

End Region

At Button Start Copy, an exception occur "Could not complete operation since a directory already exists in this path 'C:\Program Files\Data'." in
My.Computer.FileSystem.CopyFile(txtSource.Text, txtDest.Text)
