In my page, if i refer
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 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.
'DataTable' is an ambiguous reference between 'System.Data.DataTable' and 'Microsoft.Office.Interop.Word.DataTable'

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:

The message sent to browser is as follows:
The type My.API.Class is ambiguous: it could come from assembly '[on Temporary ASP.NET Files]' or from assembly '[on bin folder]'
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 a user control with GridView. GridView template has label that suppose to get custom object value Name.
aspx:
<asp:Label ID="lblImage" runat="server" Text='<%# MyData.Name%>' />
cs:
public MyObject MyData;
During page loading MyData object is null, so I'm getting exception: "Object reference not set to an instance of an object.".
How to avoid the error?
I am trying to call web reference "A" in an application.
The web reference "A" will then call a function in another web reference "B" through HTTPS connection (require certificate).
Then I keep getting the following error:
An unhandled exception of type 'System.Web.Services.Protocols.SoapException' occurred in System.Web.Services.dll
I have a url like this:
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?
Dim queryString As String = "SELECT Presenter_Assignment_.username, Presenter_Assignment_.FirstName, Presenter_Assignment_.LastName, Presenter_Assignment_.SchoolName, Presenter_Assignment_.SchoolTalk, Presenter_Assignment_.Dates, Presenter_Assignment_.Time
FROM Presenter_Assignment_ INNER JOIN UserInformation ON Presenter_Assignment_.username = UserInformation.username WHERE ('@username' = username)
When I run a page with this statement, it pops up an error saying 'Ambiguous Column Name 'username'. Why is this so? ._.
The following code always comes out with the error:
"The server tag 'asp:BulletedList' is is ambiguous. Please modify the associated registration that is causing ambiguity and pick a new tag prefix".

I want to prevent a user from entering blank spaces into a username textbox.
View 4 Repliesin 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 do have a log system and the correct error is well explicit there, but I want to give a better message to the user.
I keep trying several ways but I'm using Telerik components and well jQuery and I ended up using both ASP.NET Ajax methods and jQuery, so I use
function pageLoad() {
try { [code]....
as well$(document).ready(function() { ... }
that alert(err) is never fired even upon OnClick events
what's the best approach to avoid this message errors and provide a cleaner way?
all this happens in <asp:UpdatePanel> as I use that when I didn't know better (3 years ago!) and I really don't want to mess up and build all again from scratch

I have a simple Entity query:

I then check whether one of the result values is more recent than six months ago using an if..then like so:
If rhcexists.First.SignatureDate > Date.Today.AddMonths(-6) Then
End If
However, if there are no results returned this will return an error. Is there a way for me to tell it to act as if the date is older than six months if there is no value at all? e.g., could I in pseudo do something like:
If Exists(rhcexists.First.SignatureDate, Date.Today.AddMonths(-8)) > Date.Today.AddMonths(-6) Then
End If

I think the popup message is a poor idea because OnClientUploadError has already provided developers a good option to handle the error easily in whichever way they prefer. The worst is that if a user clicks OK, he will see a window that should be seen only by software developers. Is there any trick to stop the error alert?
View 9 Repliesi have a command like
SQLCommand cmd = new SQLCommand("insert into customers name values ('"+textbox1.Text+"')",conectionstring);
cmd.ExecuteNonQuery();
now when people enter a (') single quote, this doesnt work. how do i avoid this error as this is driving me nuts!! i cannot prevent users from entering single quotes as names like "O'Connor" contain a single quote. parameterized query doesnt seem to be the best solution as it involves loads of coding and will involve huge changes in the code. as its not a fresh app im making... can some modification in the code above so this can be avoided?
