System.IO.DirectoryNotFoundException: Could not find a part of the path 'C:Documents and SettingsAdminMy DocumentsVisual Studio 2008WebSitesElcomponics Sales-BDsamples�50841010_sd113201031833.pdf'.
Why so?
When i deployed my app on server and accessed it from client system. It is not throwing exception.What is the difference?
Still i want to confirm will it throw the same exception in case i deployed it to server and access it from client.
I am having this strange case, at first time when the page loades, everything goes fine. But as soon as I click on any link which makes any ajax request, after that, I get this error while trying to read the configuration."System.Configuration.ConfigurationManager.ConnectionStrings' threw an exception of type 'System.Web.HttpException"I am using asp.net mvc 1.0
I am using Server.Transfer("axpx page", True) in my page.aspx.vb code. This line of code is there in the Try block. The exception "error : canot obtain value" is occurred when this line is executed. This is started all of sudden in the production.I have temporarily fixed this by keeping this line after try - catch block. But I'm not sure why is this problem occurred?
I have developed my web app in 3.5 framework and deployed at high config server(15 gb ram). In my app there are some rdlc reports which always throws out of memory exception. each report has around 15-20 pages. rest of pages are working fine. there are 700-800 users hitting this site concurrently. i m checking my server utilization and its never gone beyond 2 gb. wot i need to do so that my app can utilize full memory.
when a user enters a bad email I am doing a check on this and throwing an exception message as follows, this works fine on the test site but for some reason the same code on the live site gives a "internal server error" (http code 500). The code below:
[Code]....
not certain why this is happening, I assume that it's some server or config difference between the test and live sites. has anyone seen this before? For a quick fix i'm registering javascript alert and showing the same text so it works but I would like to figure out why the code above is not working.
I have an ASP.NET application that was working fine on my server up until last night when I installed a bunch of windows updates, now it's throwing this exception : System.Security.SecurityException: Requested registry access is not allowed.Unfortunately there is some things that makes this hard to debug. I added the debug="true" attribute to the web.config file to get the line where the exception is lauched. The line identified in my code is an End If and the code just before seems benign :
A dataview is throwing an out of range exception when a page submit button is clicked. The strange part is if you change the data in the dataview by selecting a different person in the DDL the page works fine. Its only when the page loads and the default person in the DDL is when the DataView throws the exception.
The exception is thrown on the last line when I add DV.Rows(0).Cells(1).Text to the id_num parameter. I know there is a value in the dataview because it is displayed on the page. I can refresh the dataview with another person's information and the code works fine. This really has me confused. Here is a bit of the code behind.
Dim dashDataSource As New SqlDataSource() dashDataSource.ConnectionString = ConfigurationManager.ConnectionStrings("SSSConnectionString2").ToString() dashDataSource.InsertCommandType = SqlDataSourceCommandType.Text dashDataSource.InsertCommand = "INSERT INTO tblAcadReferrals(all columns and parameter info here)" dashDataSourceInsertParameters.Add("id_num", DV.Rows(0).Cells(1).Text)
What is the point of throwing an exception? It it anyways going to be caught in the Global.asax Application_Error method.
Lets say in the following code we throw an exception.
try { using (var dc = GetDataContext()) { // We are doing some data inserts here. } catch ( Exception ex) { throw ex; }
My Question: Even if we do not use try catch and throw here, any exception which will be raised here will be caught inside Application_Error method in Global.asax. Then what is the point of try, catch and throw in this case?
I have an asp.net application with separate classes for business logic and database interaction and then of course the UI. I am building a form to add a widget to a widget list table in the database. My UI collects the information and submits it to the business class. I'm going to write the business class to first double check that the widget has a name (I know I should do this in UI with validation, and I will, but this is just in case validation is forgotten) and if it does, go ahead and send the information to the database class. The database class will then attempt to write the info to the correct table using a try catch finally block. Any errors caught here are logged and then rethrown so I can inform the user. So, knowing that my database class may rethrow an error, my business class code will also be written in a try catch finally block.
So at this point I have a number of possible outcomes that I want to inform the user via the UI:
1) Everything was fine and the widget was added.
2) Something happened with the database write and the user should try again later.
3) The user forgot to name the widget.
My question is: should I write my UI in a try catch block and then throw a custom Exception with an Exception.Message in the business layer if anything goes wrong, or just have my business logic return a string that is the message? I'll want to know if the process was successful or not, because I'll want to format the actual message differently, so I'd have to use if...elseif to determine if the message was bad or not.
It seems like throwing a custom Exception in the business layer may be a good way to tell the UI something bad happened. If the UI doesn't catch anything then of course the operation was successful. Then again throwing an exception for missing data seems a bit hefty.
I am using AjaxToolkit 4.0 which suggests to use ToolkitScriptManager in place of ScriptManager. But when I am using ToolkitScriptManager, it throws javascript exception when Page_ClientValidate() in called from javascript. However, this error is not coming when ScriptManager is used. Can anybody tell me how to make Page_ClientValidate() run when using ToolkitScriptManager?
Now it doesn't throw any exception, it executes fine but receiver does not receive any mail in his inbox. How can I fix this? Edit - This is the stack trace im getting.................
then i insert an item to the top of list (at zero index):
Code:
protected void Title_DataBound(object sender, EventArgs e) { var item = (RadComboBox)sender; item.Items.Insert(0, new RadComboBoxItem("Select title...", "0")); }
It works perfect but, IF the Title field is zero and you Click EDIT LinkButton it throws an exception: Selection out of range Parameter name: value I would say that it's expected as zero index does not exist at the moment when i click edit button. I bind the combo from within RadGrid1_ItemCreated event.
In our application we have to access session objects in business class. We are using HttpContext.Current.Session to get the session value. In some cases it returns the value but mostly its throwing a null reference exception(Object reference not set to an instance of an object). We have the following code Try
If HttpContext.Current.Session("Username") IsNot Nothing then ' Statements to be executed End If Catch ex As Exception 'Log to db End Try
Here HttpContext.Current.Session("Username") is mostly throwing an exception "Object reference not set to an instance of an object" While debugging we found that HttpContext.Current itself is nothing.

When the Stored procedure is executed through SQL Server Management Studio, its taking 23 seconds,When the same Stored proc is called through web app, its throwing below copied exception. It is noticed that when the data is more than 100k records this exception is thrown other wise expected records are shown in UI. Another stored proc from the same app returns over 150k records without any excetpion. Can't conclude that the exception is in Stored proc, because it works from SQL Server Management studio, but throws below exception from Web app.
I'm a lowly DBA.I am supporting a web app that allows users to upload images (among other documents). The system is deployed and working and not having issues with the uploads. However, I upgraded my development box recently and since then I have been encountering an "access denied" issue. Initially I thought it was a simple security issue but now it seems it is more complex.
