How to identify the line nr. where the exception has occured and show a piece of code around the exception?I would like to implement a custom exception handler page which would display the stack trace, and I'm looking for the easiest way to accomplish the above. While most of the information is available through the Exception object, the source code information is not available there.
View 1 Replies I just installed Visual studio 2010 ultimate RC on my windows 7 server. It doe snot show line number. So I went to Tool->Option->Editor, however, there is no where I cna find line number choice.
I used to have Visual Studio 2010 professional beta, it has the same problem, no line number to show up. However, it has a check box: line number. Even if I check the box, still no line number to show up.
Basically I want to take the following:And make it match the styling of the rest of the application.I am creating a custom error page in my C# based project and I want it to be able to show the same information that is displayed in the ASP.NET default error page. From fiddling with reflector I can see that this is generated through HttpException.GetHtmlErrorMessage() but when I try to use this in my exception it returns null.

View 2 RepliesI knwo how to capture a line number from en exception error...but I have a need to capture the line number that certain things occur wihtout having excpetion thrown. I guess one way would be to force an exception to occur and then trap the line number but I dont really want to do that because that seems clumsy to me.
What woudl be nice is if there were some way to just say "what line of code is this?" programmatically.
so that regarldess of any code changes when I need that information to be grabbed it alwasy grabs the right value.
We're trying to write an error tracking solution for our sites and ran into something interesting. Sometimes the error exception includes the actual file and line number that the error occurred on and other times it doesn't. Is there a setting somewhere that we need to change to enable the file and line number to be returned? The two situations are each on a different server. Do we need to change something on the server?
Examples, with error file and line number:
System.IndexOutOfRangeException: Intro at System.Data.ProviderBase.FieldNameLookup.GetOrdinal(String fieldName) at System.Data.SqlClient.SqlDataReader.GetOrdinal(String name) at System.Data.SqlClient.SqlDataReader.get_Item(String name) at AccountUser.get_PracticeInfo(String sUserName) in C:xxxxxxxxxxxxeta.xxxxxxx.comAccountUser.vb:line 106
Without line number:
System.NullReferenceException: Object reference not set to an instance of an object. at Dealers_Toolbox_UserEdit.LoadRoles()
I want to get the line number of my code -- not in case of an exception though. Is there a way to capture this?

i have a radio button list that on selecting, queries a table and displays data in a textarea. now i'm trying to enhance my code so that the value of the radio button is displayed within the URL. that way i can send users links to content displayed by the radio selection (i.e. articles).
So far i've been able to place the "Article_PK" within the url successfully when the user makes a selection. now i'm just stuck on how to get my databind working again. so basically, i need to read in the value of the "Article_PK" in the url to display the data within the textarea. need someone with some mad coding skills to save the day!
