[HELP] Save File Fialog/Stream Writer - 1llusion - 02-22-2011

Hi, well, I was working on a little generator and I came across a problem,

For some reason, I keep getting "Cannot acess file.php because it is allready used by another process"

Code:
Dim ofd, ofd2 As New SaveFileDialog
        Dim SWE As Stream
        ofd.Filter = "php files (*.php)|*.php|All files (*.*)|*.*"
        ofd.ShowDialog()
        File.Create(ofd.FileName)
            SWE = ofd.OpenFile()
            Using sw As StreamWriter = New StreamWriter(SWE)
                sw.WriteLine("<?php")
                sw.WriteLine("$action = $_GET['action'];")
                sw.WriteLine("$data = $_GET['data'];")
                sw.WriteLine("if ($action == " & Chr(34) & "delete" & Chr(34) & "){")
                sw.WriteLine("unlink(" & Chr(34) & "log.txt" & Chr(34) & ");")
                sw.WriteLine("$new = fopen(" & Chr(34) & "log.txt" & Chr(34) & ", 'a');")
                sw.WriteLine("fclose($new);")
                sw.WriteLine("}")
                sw.WriteLine("if ($action == " & Chr(34) & "write" & Chr(34) & "){")
                sw.WriteLine("$open = fopen(" & Chr(34) & "log.txt" & Chr(34) & ", 'a');")
                sw.WriteLine("fwrite($open, $data." & Chr(34) & "\n" & Chr(34) & ");")
                sw.WriteLine("fclose($open);")
                sw.WriteLine("}")
                sw.WriteLine("?>")
                sw.Close()
            End Using

thanks for any help Smile

Just remove the File.Create.

Here is the whole code:

Code:
Dim saveDialog As New SaveFileDialog
        Dim aStream As IO.Stream
        saveDialog.Filter = "php files (*.php)|*.php|All files (*.*)|*.*"
        If saveDialog.ShowDialog = 1 Then
            aStream = saveDialog.OpenFile()
            Using sw As IO.StreamWriter = New IO.StreamWriter(aStream)
                sw.WriteLine("<?php")
                sw.WriteLine("$action = $_GET['action'];")
                sw.WriteLine("$data = $_GET['data'];")
                sw.WriteLine("if ($action == """"delete""""){")
                sw.WriteLine("unlink(""""log.txt"""");")
                sw.WriteLine("$new = fopen(""""log.txt"""", 'a');")
                sw.WriteLine("fclose($new);")
                sw.WriteLine("}")
                sw.WriteLine("if ($action == """"write""""){")
                sw.WriteLine("$open = fopen(""""log.txt"""", 'a');")
                sw.WriteLine("fwrite($open, $data.""""\n"""");")
                sw.WriteLine("fclose($open);")
                sw.WriteLine("}")
                sw.WriteLine("?>")
                sw.Close()
            End Using
        End If

Thanks

And, the """"write"""", how does that work? Smile

thanks

Inside double-quotes, double-quotes will appear when there are 4 continuous double-quotes.
For opening and closing, you need three of them.
