.net 4.0 - Upgrade Webforms Site From .net2 To .net4 | Accessing Referenced DLL Woes

Jan 24, 2011

I have an asp.net2 WebForms project which worked fine, including referencing a dll compiled for .Net2.

Problem is that I have now recompiled the dll for .Net4 and have also 'upgraded' the VS2010 asp.net WebForms project to .Net4 and the asp.net WebForms application won't access the dll.

The first time the dll is called I get System.NullReferenceException: Object reference not set to an instance of an object.

The new dll is accessed by other WinForms applications OK.

Whatever the problem is, VS2010 freezes and I need to use Task Manager to close it down.

Cannot Create A Process In A COM Object (written In .Net4) From An Asp (vbscript) Site

Jan 14, 2011

I'm updating an old process that already exists, which works as follows:

The user submits a form which runs the following asp (simplified, names changed):

set rb = Server.CreateObject("RecordBuilder.SomeObject")

The RecordBuilder.SomeObject was an old VB6 DLL, I don't have VB6, so I converted it to VB.NeT 4.0

The call to Calculate() works as expected, the call to StartProcess() fails.

StartProcess() is the following:

Public Function StartProcess()
strProcess = "Starting process"
Dim proc = New Process()
proc.StartInfo.RedirectStandardOutput = True
proc.StartInfo.UseShellExecute = False
proc.StartInfo.CreateNoWindow = True
proc.StartInfo.FileName = "d:AppRecordProcessor.exe"
Dim procHandle = proc.Start()
strProcess = "Started process"
Catch ex As Exception
Err.Raise(vbObjectError + 9999, "RecordBuilder.SomeObject", strProcess & " failed: " & ex.Message & "<hr />Stack Trace:<br />" & ex.StackTrace)
End Try
End Function

This fails with the call to proc.Start(), however if I copy the test ASP to a .vbs file it will work as expected.

I have changed the permissions on d:AppRecordProcessor.exe to grant execute permission to the group Everyone.

Configuration :: Deploy A .NET 4 Site To Upgrade An Existing .NET 1.1 Site?

Oct 3, 2010

I am neither a server administrator nor very knowledgable about how to configure IIS, so I have the following problem:

My client hosts their public website from their own internal server running Server 2003 with IIS 6. The current website is a .NET 1.1 application configured as a website in IIS. Within this site a separate virtual directory configured as an application runs a separate .NET 1.1 app that serves as their online webstore.

I've been tasked with upgrading the website (not the webstore) to .NET 4 and getting it installed and working on their server. My initial plan was to simply change the existing websites home directory to the new home directory from the IIS admin console and be done, but then I read that this would break the application directory that hosts their online store because .NET 1.1 applications cannot be nested within .NET 4 applications. Can anyone confirm this?

Website - Webforms Physical Site Structure With Dynamic Site Map

Feb 2, 2010

I am having a little difficulty trying to wrap my head around site structures. I have quite a large asp.net site, for which: Admins can see a user list, Each user can have many accounts, and for each account can have many items. I can picture this as a breadcrumb trail of editing a particular item. User List > Mr Bob > Accounts > BOB77 > Items > Item32 > Edit

User List = All the users Mr Bob = A user the administrator has selected from the User List Accounts = A list of the user's accounts 12BOB = The administrator has selected the account named 12BOB Items = A list of the items an account contains Item32 = The item that the administrator selected Edit = The action that the administrator wants to do. I can picture how this would look like if it was using ASP.NET MVC with the URL, but I am unsure how to map this out using Webforms, and in the physical filesystem.

This is what I have thought up about how I am guessing the physical structure would look like. Will this have to use session variables to achieve what I am trying to do?

/Users/User/Edit.aspx <- for editing a user
/Users/User/View.aspx <- for viewing a user
/Users/User/Accounts/Default.aspx <- for viewing all accounts
/Users/User/Accounts/Account/View.aspx <- for viewing an account
/Users/User/Accounts/Account/Edit.aspx <- for editing an account
/Users/User/Accounts/Account/Items/Default.aspx <- for viewing all items in an account
/Users/User/Accounts/Account/Items/Item/Edit.aspx <- for editing an item

Where can I read more about this kind of setup in a web application? Or, can someone point me in the direction of an available project that has this kind of layout?

Jquery - WebForms Site Sample?

Mar 4, 2011

What I'm looking for is a good sample of an open source WebForms site which contains demonstrations of some best practices, design patterns etc. Just want too look how experienced people apply their knowledge to build websites which can be shown to everybody without shame :)It would be good if the samples show these technologies: IoC, Entity Framework, Unit testing (with mocks), jQuery. The small samples which demonstrate the particular technology are useless as I've already examined many of them.My goal it to improve the existing huge WinForms application, so I'm not interested in ASP.NET MVC for the time being

NET WebForms - Processing String Parameters Across All Pages On Site

Jun 25, 2010

Working on an ecommerce site which will be integrated with a 3rd party vendor--that vendor uses different identifiers for stores than we use internally (i.e. their store ABC123 is our 001-321). I'm researching the best approach to inspect incoming requests for reserved query-string parameters that indicate the request is using their identifiers and map the identifiers back to our identifiers (so if the request is example.com/&theirId=ABC123 I want to transform the request to example.com/&ourId=001-321). To do this mapping I need to inspect the provided ID, execute a lookup against the database or cache, and forward the request to the specified page--limiting the modifications to just the query-string parameters (other parameters will need to be maintained, as with the details of the HTTPHeader, etc). So far I'm researching a few different approaches: Implementing it in a base Page (which already does too much, but has the benefit of our Logging infrastructure and some other injected dependencies) Implementing it in an IHttpModule Using URL RewritingUsing URL Routing (looks like routing isn't what I want, feel free to offer insight if you think it still fits) Performance cost is a consideration: the actual number of times this translation will occur will be very small compared to the number of requests not requiring it--perhaps 1%. However for another integrated site we will perform this mapping on nearly every request--would a different approach be better suited to this scenario from the previous?

Webforms Site Using HTTPCookie With 100 Year Timeout Times Out After 20 Minutes

Jun 11, 2010

I have a site that is using Forms Auth. The client does not want the site session to expire at all for users. In the login page codebehind, the following code is used:

// user passed validation
// grab the user's roles out of the database
String strRole = AssignRoles(UserName.Text);
// creates forms auth ticket with expiration date of 100 years from now and make it persistent
FormsAuthenticationTicket fat = new FormsAuthenticationTicket(1,
UserName.Text, DateTime.Now,
DateTime.Now.AddYears(100), true, strRole,
// create a cookie and throw the ticket in there, set expiration date to 100 years from now
HttpCookie cookie = new HttpCookie(FormsAuthentication.FormsCookieName,
FormsAuthentication.Encrypt(fat)) { Expires = DateTime.Now.AddYears(100) };
// add the cookie to the response queue
Response.Redirect(FormsAuthentication.GetRedirectUrl(UserName.Text, false));

The web.config file auth section looks like this:

<authentication mode="Forms">
<forms name="APLOnlineCompliance" loginUrl="~/Login.aspx" defaultUrl="~/Course/CourseViewer.aspx" />

When I log into the site I do see the cookie correctly being sent to the browser and passed back up: However, when I walk away for 20 minutes or so, come back and try to do anything on the site, the login window reappears. This solution was working for a while on our servers - now it's back. The problem doesn't occur on my local dev box running Cassini in VS2008.

SQL Server :: SQL 2008 Installation Woes?

Feb 13, 2011

I'm a complete newbie when it comes to SQL, and to be honest it frightens the hell out of me too.

I've been running a version of SQL 2008 Express for sometime, however after getting some free software off Microsoft I updated my version of Visual Studio to professional and then tried to update my Express version of SQL to 2008 R1.

I downloaded it from the MS site and proceeded to work through the pre-installation instructions, however I wasn't offered the opportunity of installing a new instance and was then advised there was nothing to upgrade on the version I had installed.

When I go into SQL management studio I can see the database I used to be able to access but can't expand it. My version of SQL is 10.0.2531.whats happening or how to work around it?

Installation :: Impersonation Woes / The Error Message Persists

Jul 26, 2010

I have a web-service that I am trying to write.

Part of it's function will be to write files to other servers accessable via file share on the same domain. With that in mind I enabled impersonation and set up the account. I now get the following error:

The current identity ([domainuseraccount]) does not have write access to 'C:WindowsMicrosoft.NETFramework64v2.0.50727Temporary ASP.NET Files'.

I have gone into the security tab for this directory and added this user with FULL CONTROL, I can reboot the server and re-look at the security tab for this directory and I can SEE that the permission are there.

If I take the impersonation account and make it an administrator it all works fine. Obviously that is NOT what I want to do.This is a windows 2008 R2 server running on a domain. The impersonation account is a domain account not a local account. The impersonation account has been added to the local 'Users' group.

I am stumped. I can see that the account DOES have full permissions on the directory, but the error message persists.Back in the days of Windows 2000 there were steps that had to be taken to set ntfs permissions that would allow impersonation (or even the asp.net) accounts to work properly. I have not found a similar document for Windows 2008 R2.

I have isolated the problem in two project which are the same except one targets 3.5 and the other 4.0This is breaking my app, and really causing major headaches.This is the mapping of the route:


Which uses a custom contraint:


This is the controller Action

In Home/Index.aspx I have created a few links:


All link have a different link text wich I use here to reffer to themThis generates the following links which are in my opinion faulty in both frameworks, but 4.0 offers no workaround.In 3.5:

actionlink = /Home/Special (?)
actionlink routevalues = /MyPrefix (This is what I want)

Installation :: ERROR: There Are Too Many People Accessing The Web Site At This Time

Jun 16, 2010

I have been trying to fix this issue for several hours now, and I was hoping to find out if someone can shed some more light on it. I get the above error on ONLY ONE virtual root in my IIS 5.1 installation. I have other web sites I am developing in .NET 2.0 and 3.5 and they seem to work fine. This is a development workstation with only 1 user, and I get this error continuallyevery time I access only 1 of my web sites - even after rebooting the machine. It makes no difference what order I access the web sites in - this one always fails and the other ones always succeed.

Note that the web site does not use frames and the changes I made to it yesterday (just adding some javascript and a few span elements to support BuySafe's new 3-in-1 guarantee program) were very minor.OS: Windows XP/IIS 5.1Dev Environment: Visual Studio 2005/.NET 2.0Browser IIS 7.0Every page on the internet I have read about this seems to indicate it must be something with the "HTTP Keep Alive" setting. I disabled this setting but it made no difference at all.I keep full backups of my machine and I restored my OS/IIS partition from a few days ago (including the full IIS metabase), but I still continue to get the same error.The error suddenly started occuring today - I just made some updates on the web site and deployed them to production yesterday (and neither my test or production servers are exhibiting this behavior). It happened after a power failure and my UPS software forced my Lenovo T500 laptop to sleep. When the power failure occurred, both VS 2005 and a browser with this web site were open on the machine. The machine woke up and the programs were all still running, but I was no longer to access this web site.I had a problem like this years ago and I ended up rebuilding the machine from scratch. Please give me an alternate solution.Full Error Message:The page cannot be displayedThere are too many people accessing the Web site at this time.Please try the following:Click the Refresh button, or try again later.

Sharepoint Woes - Couldn't Load File Or Assembly - BadImageFormatException

Jan 27, 2010

I've been working on a project that's been a rather seat-of-the-pants experience. We have MOSS 2007 and Silverlight 3 installed. We're trying to make use of some new 3rd party software, Visual Fusion([URL] While working through the tutorial I ran into a bit of an issue. All I really have to go on is the guidance package and sample stuff they provided so it's still a little fuzzy. Basically when I debug the project in Visual Studio 2008, instead of loading the default.aspx page, I get this on my browser instead:

Server Error in '/' Application.
