I'm trying to pass email addresses from an array to a stored procedure, then display the results in my gridview. I get the following error:No mapping exists from object type System.String[] to a known managed provider native type.On this line: Dim DR As SqlDataReader = MyCommand.ExecuteReader
[Code]....
I'm making the leap to move from vb.net to C#, and I'm getting this crazy error when I try to execute one sp, set a value, and then execute another sp based on the value. proc_GetSectionDetails is my first stored procedure. From that, I get a value for SectionID, and then use it for the second sp called proc_GetSectionDetails

I am using VS 2010 with an ASP.Net web application (FW: 3.5). When I run the app in VS, I get the following message:
c:WindowsMicrosoft.NETFrameworkv2.0.50727Temporary ASP.NET Files

I have deleted the temporary files/folders and as soon as I run the app, I get the same message and the files reappear. This is a show stopper and I do not know where to turn. I have searched the web, but the only thing I found was suggestion to delete the folders, which did not work.
I've just gone thru a large-ish project and renamed A LOT of namespace directives. Everything works fine on my developer box - deploy it to stage and I get:
Compiler Error Message: CS0433: The type 'ASP.usercontrols_pageheader_ascx' exists in both
'c:WINDOWSMicrosoft.NETFrameworkv2.0.50727Temporary ASP.NET Files
oot89252a5f7305b927App_Web_hodsbmv3.dll' and '

oot89252a5f7305b927App_Web_pageheader.ascx.6bb32623.bs4iljip.dll'
Yuck. Very similar to this: Deployment Project dlls cause 'type x exists in both' errors, but must be coming from a different cause.
I have none of the problems I've seen mentioned in other articles (App_Code / CodeFile directive). Worked out why it works on my machine: the website has no problem when it is in a vdir. If I remove the "PageHeader" usercontrol from the masterpage it lives on everthing is fine. If I rename "PageHeader" everything is fine. Updated: renaming the usercontrol doesn't help.
I'd had a look at the assemblies mentioned in the error in reflector; App_Web_hodsbmv3.dll contains dynamic classes for all the usercontrols in my project. App_Web_pageheader.ascx.6bb32623.bs4iljip.dll' contains the same code just for the PageHeader usercontrol. Why would ASPX decide to create the same class in two assemblies?
I just upgraded my blog [URL] to BlogEngine 1.6.1 (from 1.6.0) in order to use the reCaptcha extension. I upgraded my local code from 1.6.0 to 1.6.1, then published via FTP through WebMatrix. After the upgrade, I am getting this error:
Compiler Error Message: CS0433:
The type 'Resources.labels' exists in both
'c:windowsMicrosoft.NETFrameworkv2.0.50727Temporary ASP.NET Files
oot9fd92f8745a2ba06assemblydl3a64307f6f14811b8_0291cb01App_GlobalResources.DLL'
and
'c:windowsMicrosoft.NETFrameworkv2.0.50727Temporary ASP.NET Files
oot9fd92f8745a2ba06App_GlobalResources.md7pit6m.dll'
The source file and line number where it breaks varies, but it is always the same basic message. What differs is the "md7pt66m" section of the App_GlobalResources.md7pit6m.dll (the second file path in the error message). I was able to fix the error locally by deleting the Temporary ASP.NET Files, but I can't do this on my hosting server (GoDaddy). Is there something I can do to fix the error? Based on suggestions from the codeplex discussion page, I have edited web.config file in order to cycle the app pool, and renamed BlogEngine.Core.dll to BlogEngine.Core2.dll and then back in order to restart the blog. I have also added batch="false" to the <compilation> tag in web.config (based on this post). I have turned custom errors off, so you can see the error on my site now.

I have an asp.net web site where I'm trying to resolve what looks like a problem with ASP.NET AJAX:
Microsoft JScript runtime error:
Sys.ArgumentTypeException: Object of
type
'Sys.Extended.UI.AccordionBehavior'
cannot be converted to type
'Sys.UI.Behavior'. Parameter name:
instance
I've googled around a lot, and looked at the code presented (see below, no idea what it means) but no luck.
I've tried changing scriptmanger scriptmode to release, and a bunch of other things too.
Details:
Visual Studio 2010
ASP.NET 4.0
Ajax control toolkit 4.0
jQuery 1.4.2
jQuery UI 1.8.5
JS Code the error occurs in, inside ScriptResource.axd:
dispose:function()
{
var c=this;
b.UI.Behavior.callBaseMethod(c,eb); --------- this line
var d=c._element;
if(d)
{
var f=c.get_name();
if(f)
d[f]=a;
var e=d._behaviors;
Array.remove(e,c);
if(!e.length)
d._behaviors=a;
delete c._element
}
}
Declaration of accordion control:
<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="atlas" %>
(snip)
<atlas:Accordion ID="menu" runat="server" SelectedIndex="0"
ContentCssClass="accordionContent" FadeTransitions="true" FramesPerSecond="30"
TransitionDuration="250" AutoSize="None" Width="270">
</atlas:Accordion>
*Update: *
Added accordion control declaration as requested, is there anything else I can add that could be useful?
Does anyone have any idea about this error at all - am I right in thinking it's MS AJAX not playing nicely with other javascript (probably jQuery UI) on the page?
Solution,I had also moved ashx and asmx files at the same time as this. The Class attribute of the WebService/WebHandler directives were pointed at the wrong namespace. The moral of the story is to make sure you view the markup for all as*x files you change the namespace for by right-clicking on them and choosing "View Markup".
I'm experiencing the same problem as in this question and this link, but none of the answers fixed my problem. (edit: Setting the web.config batch attribute works, but that's a coverup, not a solution)
The problem I'm having is with a User Control that I moved from the root directory to a subdirectory within the same Web Application project. It used to work fine before I moved it. When I moved it it started giving me the error message.
It's saying that the class name exists in two dll files in Temporary ASP.NET Files. Sure enough, when I open Reflector, it's in two dlls.
If I rename the class and ascx file, everything works fine. No usages of the original name exist within any of the files in my entire application. When I rename the file, I opened all of the dll files in Temporary ASP.NET Files with Reflector, and no references to the original class name exists.
So where's this phantom reference coming from how can I fix this?
Edit: I literally grepped every file in my working directory for the solution and my temp directory for the old class name and deleted every file that contained it. I then renamed back to the original, broken name and I still get the error.

Edit:Ok, so I did some more testing on what works and doesn't work.Let's say the original file name was "BadUserControl.ascx" in namespace "MyNamespace".
I moved the file to a directory called "NewDirectory" and changed the namespace to "MyNamespace.NewDirectory". There are no copies of "BadUserControl.ascx" anywhere else on my HDD. I double-checked my TFS history to ensure the ONLY difference is the addition of ".NewDirectory" to the namespace in the markup and code-behind files.
Inside of this namespace are two other user controls named "OtherUserControl" and "AnotherUserControl".
This situation fails:
I have 2 Register directives:
<%@ Register src="BadUserControl.ascx" tagname="BadUserControl" tagprefix="uc1" %>
<%@ Register src="OtherUserControl.ascx" tagname="OtherUserControl" tagprefix="uc2" %>
These situations work:
1) I keep "BadUserControl.ascx" named as is.
I have 1 Register directive on a page in the same namespace:
<%@ Register src="BadUserControl.ascx" tagname="BadUserControl" tagprefix="uc1" %>
2) I change "BadUserControl.ascx" to "GoodUserControl.ascx"
I have 2 Register directives:
<%@ Register src="GoodUserControl.ascx" tagname="GoodUserControl" tagprefix="uc1" %>
<%@ Register src="OtherUserControl.ascx" tagname="OtherUserControl" tagprefix="uc2" %>
3) 2 Register directives without BadUserControl.ascx at all:
<%@ Register src="AnotherUserControl.ascx" tagname="AnotherUserControl" tagprefix="uc1" %>
<%@ Register src="OtherUserControl.ascx" tagname="OtherUserControl" tagprefix="uc2" %>

Of course I understand the type cast issue but why would a IIS recycle resolve the issue?
It has a part where it sends new users their first password in email.. and yes I'm getting that annoying cannot access CDO.Message object error traced back to the "Error loading type library/DLL" message. but I remember that it used to work fine with my old computer I started the development on.
1. It isn't a permission error.. like most cases (tried granting admin access to the ASPNET user)
2. I have the required dll files registered (checked them several times and even reinstalled them a few times)
3. Tried putting only that piece of code in a new application to be able to experiment.. Started commenting out blocks of code until it finally "worked" (I didn't get the error). So it seems like I only get the error if I add a mail field (which is bad since I need those for authentication..)

I've tried to work around it but can't fix this
This error is occuring randomly, and I can't seem to pinpoint what is causing it. For the most part, the code works fine. I'm confused why it works sometimes, but then suddently craps out on me, lol.It happens in the code when I call upon the asp.net membership provider. It only seems to happen when i use Membership.GetUser() to grab the logged in user's information.
View 9 RepliesI have installed the final version of Crystal Reports for Visual Studio 2010. I created a new ASP.Net project, saved it, closed it, and then came back to it later. I was prompted to convert the project because of an out of date version of Crystal Reports. But I just created the project...how can the version already be out of date? Also, once the conversion is complete the CrystalReportViewers error stating "Unable to cast object of type 'CrystalDecisions.Web.CrystalReportViewer' to type 'CrystalDecisions.Web.CrystalReportViewerBase'. I am using .NET Framework 3.5 (I cannot use 4.0 for other reasons). Is this the cause?

I have been reading many other posts on this and can not find the resolution to my issue. My problem is that i'm trying to create a visual studio project for a application that was created years ago with no project. So I have a class file in the app_code directory and I have set it's build action to "Compile" because one of my aspx pages did not find the class that was being accessed. After doing this and running the application I get the CS0433: The type '*********' exists in both error. Both paths go through the temp asp net files. The developer of this app has this call in a aspx page
MyUtils utils = new MyUtils();
Then in the global.asax he has
MyUtils Util = new MyUtils(); This is where the error occurs.
In a MVC2 project I moved a file from App_code to Content folder, compile it. Then move it back again to App_Code and then changer its Build Action to "Compile". Now I get this error and I don't know how to fix this to make my program work again:
CS0433: The type 'Helper' exists in both 'c:Users...AppDataLocalTempTemporary ASP.NET Files oot00d4b7d2553f9cApp_Code.zowyklar.dll' and 'c:Users...AppDataLocalTempTemporary ASP.NET Files oot00d4b7d2553f9cassemblydl35c6d353719f85663_cde9cb01MyProject.DLL'
