Updating GUI Before Redirect
Oct 5, 2010
I have a GUI that contains several components (combo boxes, textboxes, etc) with their associated labels. When a button is pressed, the selection in each input component is validated, and if found to contain an invalid value, the label color changes to red and an error message appears. This works fine on its own.The problem arises when invalid values are provided and then later fixed. When the user presses the button and the inputs are valid, I redirect the response to an asp using Response.Redirect, which then runs and opens a PDF report. When this happens, none of the code to change the labels back to their original color or to remove the error message runs. If I change Response.Redirect() to Server.Transfer() and the user goes back, it returns the page to its original state (removing the error messages), but I want to keep the valid data in each component.
What can I do to either remove the error messages when the user goes back or to retain the valid input from the user?Most of the controls are non-standard .NET controls and I'm working with VB.NET 2003.

I have a webpage with a form that is used to edit some object. This object contains a Collection of other objects defined like this: Public Overridable Property Employees As List(Of Employee)
On a form I can delete an employee, add a new one or modify existing one. When I click save new values are sent to the server. On a server I check if the user exists. If exists then I modify its values, if it does not exist then I add it. All employees that exist on the server and were not sent are marked as deleted (State changed to EntityState.Deleted). I try to use the following code (dbCollection = database entities, newCollection = collection sent from the form):
[Code]...
This code does not work, because changing to EntityState.Deleted removes the object from collection, and for each loop breaks, since the collection is modified...I know that I can overcome this problem by using a for loop or adding objects to delete to some other list first, but I hope maybe there is a pattern that would make my code nicer.

I need to redirect my page based off of the ID that was just created.This is my insert statement that generates the ID that I will need to fetch for the redirect.
'SQL Insert: Product table
Dim sqlInsertProduct As String = "INSERT INTO Product
(ProductName, Status, CreateDate, ModifyDate,
CreateUser, ModifyUser, Price)
VALUES (@ProductName, @Status ,getdate(),
getdate(), @CreateUser, @ModifyUser, @Price)
[Code]...
The Response.Redirect is all the way at the bottom of the page after 3 other inserts into 3 different tables. The only thing I can think of to make this work is to put the redirect into that using, but I can't because I need the other tables to get inserted into and it wouldn't make sense to redirect before the rest of the inserts.

I am using the following code to try and redirect to https, it is not working.
If Not Request.IsLocal AndAlso Not Request.IsSecureConnection Then
Dim redirectUrl As String = Request.Url.ToString().Replace("http:", "https:")
Response.Redirect(redirectUrl)
End If
What I can check, using fiddler now to look at traffic. SSL is set in IIS 6, cert is correctly installed on site.

I am using VB in VS 2008. I am tring to call an external process and redirect the input, and pars the output back to my code.I started with the useal
Dim myProcess As New Process()
Dim StringFromProcess As String
myProcess.StartInfo.WorkingDirectory = (path & "in")
[code]....
but I will need 4 of them to get to the data and it seem to me its messy coding. Is there a way to get ReadToEnd to work when reading data over TCPIP? Or perhaps a different/better way to read back from my process?

[code]Basically what this does is a users email is passed to the 3rd party site and a token is generated and returned. Then in turn both are passed together with this redirect to log the user in. I have a few others similar to this and they work fine but somehow I keep getting the Newline error in IIS. The only thing that's different from my other authenticators is that this end point URL is .ashx. My others are .asmx or REST.I've tried the HttpUtility.UrlEncode(URL) option but still doesn't work...

My ASP.NET (VB.NET) application uses SiteMaps to display a navigation menu on the top of each page. In the code behind of some of the pages, I am dynamically amending the URLs of the SiteMaps nodes (to add parameters to the end of the URL) e.g. say I have somePage.aspx.vb and anotherPage.aspx.vb and they both contain the following:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
AddHandler SiteMap.SiteMapResolve, AddressOf Me.ExpandForumPaths
If Not Page.IsPostBack Then
Setup()
[code]....
My problem is this, if I am in the code behind of somePage.aspx and I do a Response.Redirect("~/anotherPage.aspx") - then, when anotherPage.aspx.vb is being loaded, it is the ExpandFormumPaths method of somePage.aspx.vb that is hit, not that of anotherPage.aspx.vb.
My understanding is that a Response.Redirect tells the browser to do a new request to the supplied URL - I don't know why it's hitting the method belonging to the previous page.
I've tried amending the method names (i.e. not having the node processing method called ExpandFormumPaths in all classes) but I still encountered the same issue.
When I go straight to the URL of anotherPage.aspx the correct method is hit, it is only when I am using Response.Redirect that this happens.

I'm fairly new to VB.net and this is my first post on this forum.I'm creating a website in Visual Web Developer 2010 Express in ASP.NET/VB and I'm trying to find out how to alternate a Reponse.Redirect, basically I'm looking to redirect every other visitor to go to a different site.
For example:
Visitor 1 gets: Response.Redirect("http://site-a.com")
Visitor 2 gets: Response.Redirect("http://site-b.com")
Visitor 3 gets: Response.Redirect("http://site-a.com")
Visitor 4 gets: Response.Redirect("http://site-b.com")
and so on
Also, if there is a way to set a cookie for that visitor, so if they visited within let's say the last 90 days, they will go to the same site they visited before, and not be redirected by the Response.Redirect.
