Session Empty In IIS After Rebuild?
Feb 19, 2010
I'm working on an ASP.NET MVC web application and I've made my own authentication module, which is session-based (no cookies). The problem is: When I rebuild my application, I'm automatically logged of (session is empty).
Normally this is not a big problem because my application is not 'automatically' rebuilding in a production environment. But I've also made a module that changes the resource-files and after a modification of a resource file, the application seems to rebuild automatically.
So my actual question: Is it possible to 'keep' the session variables/stay logged on after a rebuild?

I have a strange problem with the session. I have global.asax with code in the session_start event. This code calls some code that I have in a helper class. When I first run the project in debug everything is fine. However when I stop debugging and then re-run the project it fails and I have discovered that once the code in the helper class is hit the session is null. If I look in the global.asax session_start code the session is instantiated before it enters the helper class. If I then re-build the project and the re-run it everything works fine again! Why does the session suddenly become null and why does a re-build fix the problem?

I have this code in a button click event:
[Code]....
When the page is first opened, Session("LeverancieFilterExpression")) is supposed to be blank or empty so the next statement should be executed but this is not happening. Can anyone explain why? I have the .IsNullOrEmpty method elsewhere in the program and it seems to work. Also, I have

I am trying to pass a key value from one page to another, using VB.net and Visual Studio 2008 Professional. I am creating a session variable in one aspx page and trying to retrive the value in the second aspx page (Dircted to by a button with the postbackurl set) However, the session object is empty when I try to access it in the second page. If, however, i put a debug hold on the code which retrieves the variable, and examine the session object from the "locals" debug window, i see contents. When I then resume the application the code retrieves the value correctly. I am executing my code using the development server that comes with Visual Studio. Could it have something to do with that?

Second Page:

Can anyone explain to me why this first example works fine but the second, which would use a little less code and in my mind appears to achieve the same result, yet throws a null ref error?
This works ...
if (Session["sid"] == null || Session["sid"].ToString() == "")
{
// session is NOT valid.
}
else
{
// session is valid.
}
This does not work?
if (String.IsNullOrEmpty(Session["sid"].ToString()))
{
// session is NOT valid.
}
else
{
// session is valid.
}

In asp.net is it a requirement to rebuild the whole page during every callback? For example my web page is split into three distinct areas and I have an update panel for each area. Lets say I want to update the third area, do I have to bother with any processing of the other two areas?
For example lets say there is a grid view in area two. The update panel in area three callbacks to update its content. Do I have to rebind the grid in area two?

I have several small web apps that were developed in VS 2005. Included among these are several class libraries used by many of the apps. I've begun to develop in VS 2008. Today I had to add to one of the libraries that was originally generated by VS
2005.
My question, now that I've rebuilt the class library using VS 2008 do I need to rebuild all the small apps that use this library?
Background: We have a production website that is composed of several small webapps. The dlls reside in the bin folder and the .aspx pages in the appropriate folder within the website structure. If I move this changed library dll to the bin folder, are all the pages that used the old library dll going to break? The changes I made to the library class will not cause them to break.

I have a solution containing 4 class library projects and one "web site" project. The web site project contains references to the 3 class library projects, whenever I make changes in any of the class library projects, the only option I see is to rebuild the web site which takes a lot of time. Is there any option that I can only update the dll references and the changes are reflected in the web site project?

I have a web application project. I have DLLs that I reference in the project stored in my bin/ folder. Well, whenever I do a rebuild or clean from Visual Studio, it will delete everything in that folder. How do I prevent this from happening?

As I understand it, I should be able to change an aspx file in VS, update in the browser and then see the changes without rebuilding the entire solution. For me thats not the case...
Edit: I use VS 2008, .NET 3.5 and development server. It is a Web Application project and I always need to rebuild to see the changes in the aspx files. I use master pages and aspx controls. I use edit and continue and have no problem updating the code behind files without rebuilding.

I recently purchased the source code of an existing DotNetNuke module in order to make a few modifications. The source of the module contains various .ascx, ascx.resx and .ascx.vb files. as well as a main.dll file. Lets call them:
myfile.ascx
myfile.ascx.resx
myfile.ascx.vb
myfile.dll
I'm using Visual Studio 2008 PRO.
I've made a few changes to "myfile.ascx.vb". When I rebuild "my_module" via Build --> Rebuild my_module, I get confirmation that there are no errors in the Error List. I then upload a fresh copy of "mydll.dll" from the "/obj/release/" folder on my local machine up to the "/bin/" folder on my DotNetNuke site.
The issue that I'm having is that the changes that I made to "myfile.ascx.vb" are not appearing on my DotNetNuke site. Are there additional files that need to uploaded? I've checked timestamps on all of my local files and the only files that are updated after the build is "mydll.dll".

I was working on a .Net 2.0 application. Late at night I upgraded it to .Net v.4. Then, as SVN was complaining I started to do manual conflict resolution. Even later than that I tried to check in my changes, then hit some conflicts so manually merged changes from the two different .csproj files.
I can't get back to where I was and rolling back to the previous version makes me lose all the code that has been written for it.
So I'm looking for a quick/dirty and reliable way of making sure my application code doesn't get lost?

I've got a solution that contains several projects. There is a main exe project which I'll call MyProj.exe that references several other projects which reference yet other projects in the solution. Additionally a few projects in the solution are not in MyProj's reference chain and aren't regularly built. There is 1 project (a class library project) named Payment which is giving me a particularly hard time. The two of MyProj's references have a project reference to Payment.dll. So the reference heirarchy looks like this:
- MyProj.exe
- Transactions
- Payment
- Accounts
- Payment
When I right click MyProj in the Solution Explorer and choose Build, everything works fine, but when I choose Rebuild, I get the following results:
Payment.dll is deleted but never rebuilt. It doesn't exist in the output directory MyProj.manifest in the output directory doesn't have a reference to Payment.dll. (What is this file? I don't remember normally seeing it in other project's the output directories.) 19 of the project .pdb files are deleted and not rebuilt This is a big problem for me because this is a ClickOnce application and when I'm publishing, Payment.dll isn't getting included in my deployment which is a problem I suspect is closely related.

I'm working on a VS2010 Solution containing an ASP.NET Website Project and 8 c# class libraries. All projects are set to compile under .NET 3.5
When I set a breakpoint somewhere in the class libraries, the debugger breaks correctly and everything is fine. If I then stop debugging, modify code in the class library, and start debugging again (which of course rebuilds the libraries which were modified) the debugger ignores the breakpoints.
Has anyone else experienced anything like this? I'm lost and it's extremely frustrating to not be able to debug after making even a single line change and rebuilding.

When editing a UserControl (.ascx) in my project, it forces a rebuild of the website when requesting the page. This really gets annoying when programming any large project, the build time goes up to 15sec+.
In the last few days I found myself looking at a blank screen more often than programming. This gets frustrating, all the waiting.

I have a sql database that on some field will have a empty string/field. I am using a Datalist to display my results. How do I not make the labels that are empty not display? Currently if the field is empty it will leave a space there which my goal is if the field is empty do not leave a white space instead move the other colunms up.

I am working with a gridview that pulls data from a SQL database based on selections in dropdown lists. The source table has six columns for attributes of the selection, but depending on what is chosen, there could be anywhere from one to six of those that are empty (all null values). When the column is empty, I would like to have it hidden so the page is less clunky and confusing.
I've searched around for an answer for the past couple days, but what I have found so far is either related to hiding columns that you know are empty which I will not know or removing them in the SQL code which I think doesn't work if the column is called for in the gridview code and doesn't exist in the query.

I added the following code to global.asax to load up several session variable when a session starts. I'm assuming that when a page goes to use the variable that I should be
1) checking at the page level that the value is valid not 0 when its not expected to be 0, not a zero-length string when its expected to have a length
2) have code at the page level that sets the values if the values have not been set as when the Session timeout, ideally putting the code in a class derived from Page and then deriving all of my pages from the new class so that the code does not have to be repeated in every page
