Hello All,
Thank you for reading this post. Here is my issue. I have an ASP.NET 2.0 web application, that requires users to login and then they are shown the welcome page on successful login(Iam not using forms authentication, user's login credentials are validated against database and redirected to welcome page). The Welcome page has a logout button, on clicking which I clear all session variables, destroy all login based cookies and redirect to the login screen again. My problem is this. After I logout and reach the Login page if I hit the back button I go back to my welcome screen with all user information even though I have explicitly cleared session and cache. Please let me know how I can enforce the login page when back button is pressed. This is what i have on my logout page.
Protected Sub lkbLogout_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles lkbLogout.Click
Session(CustomerInformation) = Nothing
Session.Clear()
'Remove all cookies
If Not Request.Cookies(ConfigurationManager.AppSettings("Cookie")) Is Nothing Then
Response.Cookies(ConfigurationManager.AppSettings("Cookie")).Expires = DateTime.Now.AddYears(-30)
End If
If Not Request.Cookies(ConfigurationManager.AppSettings("Cookie2")) Is Nothing Then
Response.Cookies(ConfigurationManager.AppSettings("Cookie2")).Expires = DateTime.Now.AddYears(-30)
End If
If Session(CustomerInformation) Is Nothing Then
Response.Cache.SetCacheability(HttpCacheability.NoCache)
Response.Cache.SetExpires(DateTime.Now - New TimeSpan(1, 0, 0))
Response.Cache.SetLastModified(DateTime.Now)
Response.Cache.SetAllowResponseInBrowserHistory(False)
Response.Redirect("login.aspx", True)
End If
'------------------
response.redirect("login.aspx",true)

Responce.Cookies is array method not function. You have to use [] not (). This stand also for Session
example:
Response.Cookies[ConfigurationManager.AppSettings("Cookie")].Expires = DateTime.Now.AddYears(-30)

Will the above solution solve my issue ? Iam using VB.NET for my coding not C#

Sorry didn't read your post very well. You coud write javascript that prevents back buttion.
But when you press back button, the browser displays a page in previous. It doesn't call a server to check if that is true. It is imposible.
But you could check every time a postback occourd for every page

Subject says it all.
I've been searching here and across the web for an ASP.NET DatePicker control.
So far, none have handled NULL values properly (unless puking is proper).
Anyone know if Microsoft will fix this in 2008? If so, I'll tell the boss to shelf this.
"Neque porro quisquam est qui dolorem ipsum quia dolor sit amet, consectetur, adipisci velit..."
"There is no one who loves pain itself, who seeks after it and wants to have it, simply because it is pain..."

If you're on 2.0 you can use the Null Coalesce operator to avoid sending a NULL value to the control.
string origDate = null;
string newDate = origDate ?? DateTime.Now.ToString();
So if origDate is NULL, it will use Now.
Hope that helps you get around your problem. If you're using VB.Net, then I have no clue if it has a Null Coalesce equivalent.

Thanks for the reply.
I think I have 1 line of VB code in my ASP.NET application.
Everything is DataBound controls, so not sure where to intercept that.
Guess I'll have to modify someone's control.
"Neque porro quisquam est qui dolorem ipsum quia dolor sit amet, consectetur, adipisci velit..."
"There is no one who loves pain itself, who seeks after it and wants to have it, simply because it is pain..."

I was wondering if any of you have experienced the following behavior because I can't figure out why it is occurring.
When I switch between code view and design view for my site Visual Studio indicates "getting file xyz.gif" in the lower left before it renders the design view. It repeats this for any other necessary files needed to display this. That is all normal. The problem is that it is taking far too long. For example, files that are 1-2kb in size may take minutes to "get". The same thing happens if I CTRL + F5 to build my site. It takes way too long. Much longer than it did before to get the files.
The other odd thing is that it seems like it requests files it shouldn't need because they haven't changed at all between edits. For example, I'll modify a gridview color and hit OK and it starts redownloading xyz.gif which it just downloaded moments prior.
This never used to happen. I am using FTP instead of FrontPage extensions to connect to the site (c# asp) as I always have. The computer I am editing on just recently had Windows reinstalled from scratch with a fresh install of Visual Studio with all updates and SP's applied. It has also been several months since I have done development on the site so maybe something changed on the web host's end.
If I use an FTP client and connect to download files from my site it seems to go very fast so I am not sure why this is occurring.
Is there some cache'ing setting that I don't have turned on in my new Visual Studio install? Is there some other setting I need to toggle to improve performance? Any thoughts or ideas to help me drill drown the troubleshooting on this more?
Thanks!

Huw moch of memory you have?
Did you terminated all unnececary process in background?
Start->Run->msconfig.exe->Startup (Modify your startup programs)
|
|
|
|

2 gigabytes of memory. Plenty of it is free. There are no unnecessary startup items running. The CPU use is very low. Whatever it is is not resource related.

Try closing all open document in VS, Try delete suo file, Or try transfers all file localy, when finished, move back
|
|
|
|

How do I delete the suo file (not sure what that is)?
How do I transfer the files locally?
Thanks!
|
|

suo file resides beside sln file. Default Path is "My Documents\Visual Studio 2005\Projects\[Your Project]
suo file is a VS state, by deliting, you will have default view. Some times this files can go over 40MB.
sln file is a Solution, witch contains a group of projects.

Use FTP Client, such as fileZilla
For local, you woud have to configer database, or connection string

Oh, I thought you meant there was some fancy way of downloading the site locally for some sort of cache'ing. I do know how to download it via FTP client. How would that help speed if I want to work on the remote site?
I am going to check the size of the suo file when I get back to the PC.

Do you have a passive mode for FTP, Al thou i don't know if that helps.
InvalidTypecast wrote: How would that help speed if I want to work on the remote site?
you will have all files, including in your virtual Server, to test and, when is finished, you put updated version to FTP. And you will avoid download and upload. Sometimes FTP requires a little more time to process command. I Have seen it happend. Of course, you could easier debugged the site. (With Breakpoints, not only TRACE)
If the Database does allow connection from remote machine you don't need to set your database. Only correct your connection string if needed.

It isn't using PASV at the moment, but I can give that a shot.

It turns out it was due to the fact these images being accessed were in a folder with 1,000 other images. Apparently this slowed down requests for these files for some reason. Once I moved these site images into a separate folder the problem went away.

I have been assigned a project that needs a treeView that shows documents listed in a grid.
Example: When a root node is selected it would show all the documents... A parent node is selected it shows all the documents listed under that parent... A child node is selected then is shows all doc under that child.
I have done extensive research on this and havne't found anything that I'm looking for.
Any help or suggestions would be great.
Thanks

We will not do your homework. Ask specific stuff.
With such question, don't expect anything.
Look other post, and then ask appropriate question.
A HINT.
Get What Treeview has, then clear grid, and write code to add to grid.

Hi
Here is the situation, I have an aspx page with 10 buttons on it, when each button is clicked I load a user control using the following statement,
Me.DGPanel.Controls.Add(LoadControl("Controls/AmexUC.ascx"))
In each control there is a Label a Textbox and a Datagrid, When the contol loads to the page, Both the label and textbox display fine but there is no datagrid, Here is the code that I am using in the Page_Load of the user control
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
logPath = Request.MapPath("~\\Log\\")
dateFrom = Convert.ToDateTime(Request.QueryString("DateFrom"))
dateTo = Convert.ToDateTime(Request.QueryString("DateTo"))
AmexDataMgr.ListForCollection(dsn, uid, pwd, PriBox, SecBox, Sys, Prod, Serv, db_app, dateFrom, dateTo, "A", "A", coll, logPath)
coll = Me.LoadCollection(coll)
If Not Page.IsPostBack Then
Me.BindData()
End If
End Sub
And the code for BindData():-
Private Sub BindData()
Me.DataGridCtrl.DataSource = coll
Me.DataGridCtrl.DataBind()
End Sub
