I am using an image button and on click of it i want to go to visited page.Now i am using - Response.Redirect(Request.UrlReferrer.ToString()),It is going to previous page, but when i am in a page of some user details where the link is looks like - users.aspx?userid=25 and i visit some other page and click back(image button) i want to see the same userdetail page. How to track that.
I have a search page with a couple of pulldowns. Dependig on the values of them I show a grid matching the searched criteria, basically a table with links the user can navigate to. My problem comes when the user wants to navigate back. At the moment I have a "Back" button which simply redirects the user to the initial search page. I think it would be a good improvement to have the values of the pulldowns filled in with the values the user selected, this way when he presses the "Back" button he would not have to restart the whole search process again.
I have created a console application. So this is the problem. I have set a main menu, when I input A, it sends me to menu A, but how can I go back to the main menu? What is the correct code should I use?[code]...
On my current project I want to deny going back once my customers hit submit button and redirected to the final page. How can I deny from going back to previous page or some mechanism to expire the page if the back button is clicked. I tried this code and it didn't work.
I have a menustrip, in which i have put a BACK option so that the user can go back directly from where he came to the current form, as there are many form which leads to the that particular form.
I am currently having a problem in my SQL Statement . I am creating a back and next button and about the Next Button it works just fine. But in previous button its kinda ok...but the problem it goes at the first row not the previous of the selected row.
Here is my SQL STATEMENT... "SELECT t1.* FROM (SELECT RecordID FROM tbl_assessment WHERE StudentNo LIKE '%" & txtstudentno.Text & "%')t2 CROSS APPLY (SELECT TOP 1 * FROM tbl_assessment WHERE RecordID < t2.RecordID ORDER BY RecordID ASC) t1"
I have a need for a button to take the user back to their previous page.Because of how this page is accessed, the only way to do this is with javascript using history.back()
This part works perfectly apart from the fact when a user goes to click a button on the page they have gone to back to, I get the error that Request.QueryString is not supported in this context.I'm guessing the Request object is lost when javascript is directing the user to the previous page.I cannot use Request.UrlReffer either because the the nature of the back button. (it causes a loop at times).
I have a routine that has an if else statement at the else part it calls another routine. Within that routine it has a msgbox script. At the part that is actually is suppose to show the msgbox it goes back to the previous subroutine at the else statement and runs again but this time it displays. I have never seen this before.
THe code is posted below.
1 Else 2 Me.lblTurnsLeft.Text = Me.lblTurnsLeft.Text - 1 3 If Me.lbltimer.Text = "0" Then

We have a server application and a client application that communicates with each other using socket.
When the server application sends 2 messages about 16-31 ms apart, the 1st message is received by the client application with little delay (like 16-32 ms after it was sent). But the 2nd message is received by the client application a lot later (like 200 ms later) than when it was sent.
We already disabled Nagle algorithm (set NoDelay = True) in the socket in both the server and client application.
We are having problems with sending back to back emails on one of our web sites. The site is built with .net framework 2.0.We can send the first email without any problems on every try. But to send a second email you need to wait about 20-30 minutes.the problem.One thing we tried was changing the smtp email server. We tried a third party smtp server but the same problem persisted. So I think the problem is not with the smtp server but with our .net code.
I am creating an application that will be faced with multiple decisions to make and I want to know if it is possible to create around 20 if statements to excute or decide between before excuting?
The application will encounter multiple websites but each website will have the same elements but not neccessary in the same order so I was going to tell the app to loop through the IF statement and if the condition is met to run that sub routine where it starts over and loops through the IF statements until next condition is met.
Is this possible in VB.NET or is 20 or so IF statements to many to use at once?[code]...

I am working on a project which requires me to connect to a MySQL database. From there I query the database and need to do work on the returned values.
I can query the database just fine. However, now I need to do work on the results. The two columns returned are user_name and user_password. The rows are the user accounts. I would like to take my query results and put each column into its own arrary().
[code..]
Instead of writing the results to the console, I would like to write each column to an individual array. Is there an easier way to accomplish this task? Or, what is the code I must place within the loop to do this.
i want to fill a Datatable with a Datareader row by row but get an exception because the reader's columns have a different order than the Datatable's columns.
Why and how does a Datatable loads itself with a Datareader correctly, even so it has a column collection with different order?
I need to calculate values for every row so i dont want to load the Datatable completely but row for row. It has 25 columns so i dont want to set it all manually.
There must be a chance to load/fill/add a new row from a datareader without having the same column order(reader.GetSchemaTable?).
Following is what i have but what doesnt work:
Using reader As System.Data.SqlClient.SqlDataReader = command.ExecuteReader 'next line works(configInfo.DataSource is a Datatable)but is inappropriate configInfo.DataSource.Load(reader)
I have this sub as part of my login / logout system. When this sub is called to login users it works perfectly, but on logout it throws an error that doesn't make any sense to me.
[Code]...
This sets a nonsense email address so that when validate_session searches for a valid email/session combo in the db it trips the destruction of the sensitive session data.
The question boils down to this: Why is the error being thrown when the logout sub calls validate_session?
