Question

I use this code in my VB.Net application

Protected Sub btnBHNas_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnBHNasBackup.Click

    'System.Diagnostics.Process.Start("batch\backupbhnas.bat")
    Using writer As StreamWriter = New StreamWriter("C:\backupbhnas.bat", True)

        writer.WriteLine("@echo off")
        writer.WriteLine(" echo ""Specify username""")
        writer.WriteLine("set /p Name=")
        writer.WriteLine("net use k: ""\\backups\back-ups""")
        writer.WriteLine("mkdir k:\%name%")
        writer.WriteLine("set drive=K:\%name%")
        writer.WriteLine("set backupcmd=xcopy /s /c /d /e /h /i /r /y")
        writer.WriteLine("echo ### Backing up My Documents...")
        writer.WriteLine("%backupcmd% ""C:\Documents and Settings\%name%\My Documents"" ""%drive%\My Documents""")
        writer.WriteLine("echo ### Backing up Favorites...")
        writer.WriteLine("%backupcmd% ""C:\Documents and Settings\%name%\Favorites"" ""%drive%\Favorites""")
        writer.WriteLine("echo ### Backing up Desktop...")
        writer.WriteLine("%backupcmd% ""C:\Documents and Settings\%name%\desktop"" ""%drive%\desktop""")
        writer.WriteLine("net use k: /delete")
        writer.WriteLine("echo Backup Complete!")
        writer.WriteLine("pause")

    End Using

    Dim myFile As String
    Dim myDir As String = "C:\"
    For Each myFile In Directory.GetFiles(myDir, "backupbhnas.bat")
        File.Delete(myFile)
    Next

End Sub

and it works. However, when I use it in a button in ASP.Net it does nothing. Am I missing something?

Answer 1

if you need to write file in C drive your application may need administrative rights(Under Vista and beyond). Check your exceptions and it will help you to find exact issue.

Try

    //code 

Catch ex As Exception

   // check exception if any

End Try
