I have an ASP.NET web application that takes user input across several forms. Sort of like a wizard. On the first form, the user enters information then clicks the "Next" button. In the Click event of the button I save some information to the Session object (via Properties in the Master page). I then Redirect to the next page. Here is an example of what I am doing:
protected void NextButton_Click(Object sender, EventArgs args) { //Go to the next form Master.SessionVal1 = Value1; Master.SessionVal2 = Value2; Response.Redirect("~/TheNextPage.aspx", false); }
In the MasterPage.cs..
public long Value1 { get { return (long)Session["Value1"]; } set { Session["Value1"] = value; } }
public long Value2 { get { return (long)Session["Value2"]; } set { Session["Value2"] = value; } }
Pretty basic stuff. When I run this in debug mode in VS2008 it works perfectly. When I push this to a test server (IIS7) I get NullReference exceptions when I try to access Value1, Value2, etc. which is stored in the Session object. UPDATE: I have discovered that if I migrate the code to one server I get the problem as described above. BUT, if I promote to another server it works as expected. Both servers are Windows Server 2008 with IIS7. I have looked at the application pool settings and the state management settings and I do not see any differences.
I got a problem regarding CSS in my pages. I managed to apply styles to my page using css and everything looks fine in the Design view. I ran it on IE8 and everything is working fine. Now after I returned to Visual Studio, added some rules to my CSS, and noticing that everything is working fine in the Design view, I ran it again in IE8 and nothing has changed. The rules I added was ignored and it looks the same. I ran it on Firefox and Google Chrome and it's working fine.
But if I ran my project in IE8 through IIS7.5, everything is working fine so it means, the problem is within visual studio 2010.
I am currently working on this situation that I could not find any other resources online to help me Everything is working fine through VS2008 debug mode, or run without debugging ( database connectivity and everything works)but however when i copy the whole project and set up the IIS, everything work except for database connectivity. I could not seems to read from the database which currently I am using a attached .mdf file
the error shown is as below :
Server Error in '/' Application.
Object reference not set to an instance of an object. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.
Source Error:
[Code]....
Source File: Signup.aspx.vb Line: 23 Stack Trace:

but however when i run on VS 2008, I am able to read the data from the database successfully,
I dragged-and-dropped a few image buttons on my VB.net page. I put a break point on the AddButton Sub routine.
When I run debug and click the button it never picks up on the break point. What's up? Is there something about image buttons that I'm not aware of?
Example of one image button and click button sub:
[Code]....
[Code]....
Update: I've just now noticed that whenever I put a breakpoint anywhere in this project and run debug, it never executes the breakpoint at all. Do I need reinstall Visual Studio?
i wrote a sending email function that only works on my debug mode(debug local server) when i publishing and hosting C# code that function doesn't work. This is my email configuration function
any way to deploy code with both release and debug mode together. I know it is logically impossible.
My requirement is to deploy debug based aspx page(for temporary) in release mode build in prod.. the concept is to avoid to put full release build on production again & again.
I am using vs2008 sp1. I am building web site with aspx. I am also using an ajax control. My Site was working normally. I could run it from f5 and it would stop at a debug point. I added an additional aspx page. Then I got a strange error. When I pressed f5 a message box appeared saying that I had not made this version with the debug option. Then from reading an internect post I disabled only my code. That got rid of the message box error but now the debugger does not stop at any break point? Of course this happen when I need to go live with this project in a day.
We have a ASP .Net based web service setup and hosted on a IIS v6.0. We wish to turn on custom error and disable debug mode. I understand these can be accomplished by modifying the web.config and machine.config file. However, since web service does not have a UI...please let me know if the changes made to the config files will take into effect. The reason why we wish to do these changes is because, our external auditors have flagged these as a vulnerabiity.
I am developing a web site in Visual Studio 2008. I have a project for the web application and several class libraries as references. When I add the references I select the file under bin/debug in the class library folder. When changing the project to release mode the references still point to the .dll in the debug folder. Shouldn't this change automatically. How should I add the references so that debug and release are properly referenced?
We all know that we should only be publishing our ASP.NET Web Applications with release build type, so why do I not get a warning when I trigger the "Publish" command in Visual Studio 2008, for a project configured to build in debug mode? Sure, there might be cases where I need to publish a debug build to a development or test environment, but answering yes in a confirmation dialog would be acceptable in these cases. Is there an option that I have overlooked, forcing Visual Studio to warn me every time I try to publish a debug build? Yes, we could just ban using the "Publish" command and use a more solid build management tool, but this involves a change of process and right not be an option in this particular case.
I have a webcast site that lists them in a gridview. Users have two options, either play the video directly or go to a details page on it and play from there. When the user plays the video directly I need to update the count of how many times it has been viewed. When I run the page from my local machine in debug mode it correctly updates the counter. When I run the page regularly, both from my local machine and on the server it does not update the count, but it does open and play the video. It doesn't give any error messages in any method of running. The only difference between running it on my local machine vs production server is that I have to comment out the authentication code on my local machine. The authentication programming was created by someone else with far more knowledge and I only barely understand how it works. For that matter this site was originally created by that same person. He included the hit counter on the details page but forgot to add it on the front gridview page, so I'm modifying it based on his code on the second page.Important parts of code behind and part of the gridview listed below. Yes I know the means of creating the first connection string is bizarre. I think it has something to do with the authenticate files that makes it work. In the past it has always worked for all connections in code behind but for some reason wouldn't work in the btnPlay subroutine this time, hence the second connection string definition.
I got a project when after opening in visual studio 2005 in build mode drop down, only debug mode is shown but release mode not shown.Project builds successfully in debug mode is there a way to enable release mode.
gaining mode changing for formview in VB.The problem is that, the current mode im using was ReadOnly, and i want to add some button so thatit could connect to Edit mode in the same formview.Is it necessary to add modechanging and modechanged in the back code?
I wanted my local iis running application to connect my database in sql authentication mode rather than windows mode,
but it is showing errors of " Cannot open database "aspnetdb" requested by the login. The login failed. Login failed for user 'DBUser'. ". i also ublocked port from firewall,and allowed remote connection of mssql from sql manager, enabled TCP/IP and named piped protocols from SQL surface config, and with sql manager i also changed server authentication mode to sql from windows. my datastring is <add connectionString="Data Source=PARTHIV-PCSQLEXPRESS;Initial Catalog=aspnetdb;User ID=******;Password=******/" name="LocalSqlServer" providerName="System.Data.SqlClient" />
i made a user named DBUser in database as well i don't understand where it gone wrong ???
