Error On Ambiguous Reference Points To Same Method Twice
Oct 25, 2010
I used this brilliant solution to convert a linq query to a datatable. But I'm getting a strange error when running it. Build succeeds though.
Compiler Error Message: CS0121: The call is ambiguous between the following methods or properties:
'Gruppkoll.App_Code.ConvertToDataTableFromLinqResult.ToADOTable<Gruppkoll.MessageSet
(System.Collections.Generic.IEnumerable<Gruppkoll.MessageSet>)' and
'Gruppkoll.App_Code.ConvertToDataTableFromLinqResult.ToADOTable<Gruppkoll.MessageSet (System.Collections.Generic.IEnumerable<Gruppkoll.MessageSet>)'
I've tried re-building it and restarting the IIS. It seems as there are two classes with the same method but I've checked this and that's not the case. I'm using .NET 4.0 ASP.NET Webforms.
using System.windows.forms; using System.web.webcontrols.....
Textbox ambiguous reference error is occured from webcontrols and forms, how can i rectify this error... but i need those two namespaces in my asp.net page.
I am getting a CS0120 error when trying turn a button visible after checking some variables. In plain english, If AmmohelpSession.UserActions contains AmmohelpEnums.UserAction.ArticleEdit then turn the Edit button visible. Here is my comparison:
[Code]....
In the code behind for AmmohelpSession, a public class AmmohelpSession which contains a private variable: private HashSet<UserAction> _userActions; has been stated. In that same file, there is a public function for the UserActions that does a get or set method.In the code behind for AmmohelpEnums, we are setting byte variables to specific actions. Mine would be something like:
I have one project in TFS and once I get latest version it gives following error. "Resource is ambiguous, imported from the namespaces or types 'System, System.web'". Even I have checked twice that there is no duplication but still giving error.

I am integrating third party Web Page Management CMS solution into my web application. I am getting the following error when I try to recompile:
Parser Error Message: The type 'oboutSolutions.ManageWebsite' is ambiguous: it could come from assembly 'C:VS2010 ProjectsTestCMSCMSinoboutSolutions.DLL' or from assembly 'C:VS2010 ProjectsTestCMSCMSinCMS.DLL'. Please specify the assembly explicitly in the type name.

The problem occurs when debugging a Web App, speciically when making a request to a WebMethod of a WebService.The project compiles just right. It generates My.Website.dll on bin folder and if I publish the Web Application. It works fine.The asmx file is on the root of the application. The CodeBehind file is on App_Code and its marked to be compiled to generate My.Website.dll.The way this person exposes its problem is somehow similar but I get starting to be lost when he talks about a proxy class and shared dlls I don't use.
I have an aspx page that is getting an Object Expected javascript error on submit, but when you break into the error the breakpoint is somewhere in the middle of the __VIEWSTATE input html element.A javascript stack dump shows just "{anonymous}(null)".What does this mean and how does one go about debugging further?
http://www.somepage.com/main.aspx. In this page, when I click on a link it takes me to a page http://www.somepage.com/cental.aspx?cid=200. So in the cental.aspx.cs page I did the following in the page load:
if(request.querystring["comp"].tostring() != null) { //do some thing [code].....
So I got an error like: object reference not set to an instance of reference.My problem is, I am using the same page. So when I go from some page, I will have "comp". but other times not. So when there is no "comp", how do I handle it in request.querystring?

I am creating an Asp.net web site which will support dynamic data. When I am creating a dynamic web site from Scratch (from template in VS) all is working fine. But when I am trying to add dynamic entity (.edmx) file and running the application I am getting following error
"The method 'Skip' is only supported for sorted input in LINQ to Entities. The method 'OrderBy' must be called before the method 'Skip'. "
in my default.aspx page i have a dropdown List and a textbox with a submit button below that there are 2 listbox... and the dropdown list holds the names of the listbox
my logic here is to select an item from the dropdown list and put some text in the text box and submit the form which will add an item to the listbox selected.. but when i do this i get an error saying Object reference not set to an instance of an object. i tried to figure out the problem and found that when i remove the reference to the Site Master Page it works fine and when i undo and apply my reference back to the Site Master Page i get the same error.
I don't know what I'm making wrong.I have a submit button, and on click it should execute the funktion in the code behind, but I get the error that the funktion is undefined.this is my code in the .aspx webform:
I have seen 2 methods to handle error in project. One is using try catch in every method and another is using custom page and error log file .I know both method. Which one is the best method?
I'm helping out a colleague on this one so if I'm missing some details that's why.We have an asp.net 3.5 web application calling a WCF service. Originally the app used a "Web Reference" to register the service however after having some trouble and burning an incident with Microsoft their solution was to replace the "Web Reference" with a "Service Reference" to the WCF service.This is great except the problem is that when we create a Service Reference, the method signatures are different than they were when a Web Reference was used.From what I've read this may be expected, however in our case this would mean some significant changes to the application and of course it was due yesterday...so......I'm wondering two things:Is it normal/expected that method signatures will change based on the reference type?Is there a way to create the Service Reference that will generate method signatures identical to the original Web Reference?
I have just asked which one is better?Static Vs Non-Static? [URL]I would like to take this discussion one step ahead.Consider If i pass reference of Panel control as parameter to Public static method, will static method still rules in performance?
I am using grid view as mentioned below, it is giving me error "object reference not set", but if comment allowpaging and pagesize lines, it works. let me know whats wrong I am doing?
How do you reference an asp.net control on your page inside a function or a class. private void PageLoad(object sender, EventArgs e) { //An example control from my page is txtUserName ChangeText(ref txtUserName, "Hello World"); } private void ChangeText(ref HtmlGenericControl control, string text) { control.InnerText = text; } Will this actually change the text of the txtUserName control? I tried this and is working private void PageLoad(object sender, EventArgs e) { ChangeText(txtUserName, "Hello World"); } private void ChangeText(TextBox control, string text) { control.Text = text; }
