After Upgrading / Getting Contains Is Not A Member Of System.array Error
Aug 17, 2010
I have a website I developed in VS 2008 targeting .net 3.5. It has worked well. I recently upgraded to VS 2010 and needed to make a few changes to the site. However, I'm receiving compile errors (haven't made any changes to the code yet--was just launching the site to make sure it worked ok). I get "Contains" is not a member of system.array. Everything I've read states that the contains method was added in .net 3.5, which I know to be correct because it was working in VS 2008. I've been targeting .net 3.5 in VS 2010, but it still isn't working. I also used linq quite a bit with linqkit to do dynamic queries and all of my linq queries were saying my queries weren't queryable (I don't have the actual error in front of me). Anyway, to fix that one, I had to import system.linq (I previously had system.data.linq and it was working fine). To reiterate, I haven't targeted my site to .net 4 in VS 2010, I've left it targeting .net 3.5.
I tried converting my arrays to arraylists since arraylists were still pulling up with a .contains method, but then it broke my linqkit queries when I ran it on the site.
Here is my linqkit query:
Dim str() As String = archlist.ToArray(GetType(String))
Dim str3 As New ArrayList
str3 = ArrayList.Adapter(str)
predicate = predicate.And(Function(l As CompatTesting) str3.Contains(l.application.cpuarchitecture))
Before, I didn't have the arraylist conversion, I just had str.contains and it worked great to generate a sql "in" statement. Now after using the code above, the site launches, but when I actually run the code, I get Method 'Boolean Contains(System.Object)' has no supported translation to SQL. I also tried upgrading my linqkit dll to the latest version but it didn't help.
My questions are, since I'm targeting the same .net 3.5 framework in 2010, why is it not allowing me to use array.contains anymore? Maybe if I can address that issue, it will fix my linqkit issue where it says "contains" has no supported translation to sql.
My web site used ASP.NET 3.5 SP1, MVC 2, and EF. Last night I tried to upgrade to ASP.NET 4 (& EF4) under VS2010.
If my views are compiled (MvcBuildViews property is true), then the build fails with this error message: Error 5 Could not load type 'System.Data.Entity.Design.AspNet.EntityDesignerBuildProvider'. C:WindowsMicrosoft.NETFrameworkv4.0.30319Configweb.config 129
It's actually complaining about my system web.config file.
If MvcBuildViews is false, then it will run (and compile the views normally just fine).
OS: Server 2008 R2, all updates applied at time of writing.
I have recently developed a new vs2010 web application that I would like to add to my web site.
The existing website was developed using vs2008. The web site is hosted on a windows 2008 server running iis 7. My new web application sits below my main website i.e. mywebite mywebsite/mynewwebsite
I have set the application pools for the mynewwebsite to be asp.net v4.0, leaving the application pools for mywebsite as .net v2.0 If I try and open my new web application i.e. [URL] then I get 500. Internal server error. I assume that it is iis that is unhappy here. Do I have to rebuild the whole of my web site to be vs2010 using asp.net v4.0. If I do should I use ASP.Net v4.0 or ASP.net v4.0 Classic for my application pools, and should I have a separate and distinct application pool for each of my web applications ( I have 4 of these) Just to clarify my clients can log on the web site as

Argh.. I've run into thei before,but can't remember how I solved it.I have a gridview with a button in a template field.I've added an event to the button,but am getting the dreaded 'RowIndex' is not a member of 'System.EventArgs' error.
I'm trying to grab the value of a label in the gridview for the row that is selected when the button is clicked.Should I be using something other than e.RowIndex?

I have to get the value from a textbox (not bound) that has been put into a formview control. The Submit button also resides in the formview control. I have this code in the button's click method:
Dim TestValueTextBox As TextBox = New TextBox [Code]....
to get that value entered and store it into the enteredValue variable (and yes, I know I have to do validation, etc). But when this runs, the value of the text in the textbox is "". I tried to put this up in the page load event, but then I get an error about declaring New.
I have a webform that has a formview (fvwContract) and inside itemtemplate there is a Tabcontainer with three tabs (invoice (spanish: factura), receipt (spanish: recibo) and beneficiary (spanish: beneficiario). I have another formview inside invoice tab (fvwFactura) with many textboxes that I need to manipulate in code behind. The thing is that I canīt reference any of them like the following:
I struggling trying to insert the value I select from a "DropDownList1" country list into a TextBox inside a FormView1. I have tried the following but It wont insert the text:I also tested on a textbox1 outside the FormView1 and it works but just after clicking Cancel or Inser in the formView1.
i was normally using VS2005 and SQL server 2005... i upgraded to SQL Server 2008... and then... i could not build my project anymore... because of this error: 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.
I upgraded a Website to use ASP.NET 4.0, from 3.5. This involved setting it up on a different server, with the same hosting company. I'm using a shared hosting plan on Windows Server 2008.
Since migrating, it gives an error message when I try to login to the site:
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)
I'm using the same connection string as I did in the old version, which always worked. I also changed the permissions for the database to allow connections from the redeployed Website, via the host's control panel.
I have searched the web.config, and the source for the site, and I haven't been able to find a connection string that looks incorrect.
I've contacted the host about it, in case it is a configuration issue on their side.
I am having some trouble upgrading an existing SQL Server 2000 Reporting Services installation from an old server to a new one commissioned for this purpose, which is running SQL Server 2008 Reporting Services. I have been following the instructions here: [URL] but after trying to connect with reporting services 2008, i get this error: The version of the report server database is either in a format that is not valid, or it cannot be read. The found version is 'C.0.6.54'. The expected version is '147'. (rsInvalidReportServerDatabase) before starting the process, I ran upgrade advisor and got back the following results:
Description Setup can upgrade a SQL Server 2000 Reporting Services instance that uses a SQL Server 2000 Database Engine in the same instance. However, upgrade is blocked if the report server database is in a different instance, on a remote instance, or runs on a remote SQL Server 2005 instance in SQL Server 2000 compatibility mode.
***** *note, our reporting services IS in the same instance as the SQL Server 2000 database engine. However, upgrade advisor still reported that this instance can not be automatically upgraded. *****
Corrective Action Choose either approach to continue with the upgrade: Upgrade the Database Engine instance on the remote computer before upgrading Reporting Services. The server cannot be in SQL Server 2000 compatibility mode after upgrade. Move the reportserver and reportservertempdb to a SQL Server 2005 or SQL Server 2008 Database Engine instance, and then use the Reporting Services Configuration tool to connect the report server to the database.
so, I went with option 2, move the database then connect. I have: -backed up the ReportServer and ReportServerTempDB databases from the old server, transferred them to the new and restored them to the 2008 Server as ReportServerOld. -I then renamed the old database to ReportServer and ReportServerTempDB, as this is required to use the database as a source apparently. I had to of course change the existing database names to ReportServerNew to perform the rename. I backed up the symetric key for this installation using the rskeymgmt utility...............
I have two member roles at my project: 1.) Administrator 2.) Member
From the toolbox in Visual Studio 2008, I have dragged and dropped the create user wizard into the stage. I aim that a guest can register itself and automatically join the "member" role. Not the role "administrator". How can I do that?
'System.Array' does not contain a definition for 'FirstOrDefault' and no extension method 'FirstOrDefault' accepting a first argument of type 'System.Array' could be found (are you missing a using directive or an assembly reference?)
What am i missing Ctrl . does not work here ( I am using MVC 2) :(
its for getting the string length from the metadata of a class
var stringLength = member.Member.GetCustomAttributes(typeof(StringLengthAttribute), false).FirstOrDefault() as StringLengthAttribute;
Its part of some code i found on the net for a custom helper to create textboxfor with Maxlength without having to add to to ever textbox for manually.
I am using a webservice (provided by webservices.nl) to extract company data depending on a company number.
myserviceBusiness = new nl.webservices.ws1.Webservicesnl(); nl.webservices.ws1.BusinessDossierV3PagedResult result = null; result = myserviceBusiness.businessGetDossierV3(KVKnr, "0000", 1); string address = result.results.item.EstablishmentPostcode;
VS underlines only "item" in curly red line Error/ 'System.Array' does not contain a definition for 'item' and no extension method 'item' accepting a first argument of type 'System.Array' could be found (are you missing a using directive or an assembly reference?)
So the problem is that intellisense doesn't recognize item and also streetname. When I take something else from that message, it works :
I've looked everywhere, Google, here, Bing, etc, and I haven't found anything that could help me with this error. I am trying to databind an asp:hyperlink using this code:
