I'm trying to implement a file upload system and I don't really get what to do.
I'm looking for the easiest way to do it. After long researches, I've found those explanations.

So, here is the things I've done inside the view :
@Code
Dim fileName As String = ""
If (IsPost) Then

Problem : GetHtml is not a member of 'System.Web.UI.WebControls.FileUpload'
What can I do to fix this? Is it the good way to handle file uploads?
a datacontext defined in a module(domain services ado.net ria)a page having add/delete methods whenever any method is executed, it is found that all the previous actions (NEW RECORD ADDITION and DELETION OF RECORDS) are carried out before the new action is carried out normally
this behaviour is not prominent but "when using break points and inspecting the values of the variables and table object to be added to context, it is clear that all the previous actions take place again. even when the datacotext. savechanges is called, even after that still all actions carried out on the datacontext repeat themseleves, when any new action is to be carried out
I am working on a program using VB.Net 2010 which will enable me to setup groups of files & folders for back up with syncing capabilities etc. I have a concept program which is based on some sample code I found out in one of the VB.Net forums. I have modified it from a command line based program to a form based program. At the moment I consider this code to be a "concept" program which once I have the various copy/sync routines developed and debugged will be integrated in to another program I wrote for
creating "Back Up" groups to automate the process. There are some 3rd party programs that do similar things that I want to do such as Microsofts Sync Toy, but none of them offer the grouping and exclusions options that I am going to program in to this backup/sync program.
So here is my problem, I have the included code taking two folders, a source and a destination, and copying everything from the source to the destination. It will skip over any unchanged files/folders and will delete anything found in the destination folder that is not found in the source folder and it will update all files in the destination folder that have a newer version in the source folder. In other words it will mirror image the source to the destination but will be smart enough not to copy unchanged items from the source to the destination thereby saving a lot of time. The sync part of the program is working fine, the displaying of the progress and results is not.

In my project, I got a page that creates guest users for a number of products chosen.Basically you tell the application how many users to create for each product you choose.When you click 'Save' I generate the guests, save their username + password (before encryption) in a csv file that I transmit at the end of the process, and finally redirect the user to the index page.The problem happens at the file transmission and the consequent redirection to a new action:
Private Sub DownloadCsv(ByVal csv As List(Of String), ByVal filename As String)
Dim sb As New StringBuilder()
For Each Str As String In csv
[code]....
What's happening is the page transmitting the file to the browser and never doing the redirect that follows.I read a bit on the matter and found out that once you add an Header to our Response object and Write a file, it will automatically close the Response. If I'm wrong, please correct me.How can I make it possible to transmit this file after the user has being redirected to the Index or Redirect to the Index after he either saves or cancels the file download?

The below code for some reason isn't working with filefront. I'm grabbing the URL that returns the file to download but the wc.downloadfile() code doesn't download the file. It creates an empty file called 100.rar in my temp directory on C: but doesn't have any data. Is there something I'm doing wrong or is filefronts redirect messing something up? If I put the URL I get with the fixUrl variable, it pops up the file to download in my internet browser fine.

I'm quite new to MVC and while I've been trying to follow the best practices , I believe I may not be understanding certain fundamentals of either
-a. Using models and viewmodels appropriately
-b. Passing models into a controller for validation purposes.
The general purpose of my program is to select a stored procedure from a list of stored procedures, create a form where the user can fill out all the appropriate input variables, and then to execute that stored procedure. The tool is for non-technical people, so I'm eventually going to have to do a good deal of input validation.
As such I have four models: A Script Model, a Parameter Model, a Parameter Enum model and a Query Model, and two viewmodels: a paramviewmodel that generates the form to fill out, and a scriptviewmodel that creates a listbox filled with the possible script choices. I am using a prewritten database system to fill out my viewmodels in an init method in my controller (which I'm not sure is the proper way to do this?).
The viewmodels are as follows:
Imports System
Imports System.Collections.Generic
Public Class ScriptViewModel
[Code]....
I'm trying to work out the functionality. Also, I think this may be too much code in the view, even though most of it is display code.
Anyways, I have two main questions. One, does creating a model in my controller, calling an init method on it, and then passing it to the view make any sense in an mvc context (if not, how would I proceed?). Two, if I want to perform validation on the form I output in my htmlhelper, but I want to use my query model validation (and not my paramviewmodel), how can I do that? Most of the examples I've seen involve a controller that recieves an appropriate model variable, and the binding is performed outside the controller itself. They then just check modelstate. Is there any way I could do something similar here?
Edit: Is there any way I can make the syntax highlighting less crappy?

The generated excel file is fine, 1125 rows, and 4 columns shown.A test program in windows form is also working fine regardless of how many rows.[code]I couldn't find a solution to my problem as well. What I did eventually was to run the process using another separate windows service. The code works perfectly fine running from a windows form or service program, but not asp.net, not sure why.
