Jun 18, 2010
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.

How do I fix this error?
I'm running .NET Framework v4.0.30319 so the Framework shouldn't be an issue. I'm not using any DLL files or bin directories. How do I setup the IIS/Virtual Directory if I'm using Forms Authentication for the whole website using VS2010?

I have built an ASP.NET (.NET v4) application in VS 2010. It is working just fine. But when I try to create deployment package (so I can deploy it in our test IIS 7.5 Server), it gives me error like this,
Error 1 Could not open Source file: Could not find file 'C:11-2 estobjDebugCSAutoParameterize ransformedWeb.config'. 0 0 test
Thing is in past, I had deployed the SAME application using the SAME method.

I'm using MSBuild with CruiseControl.Net to run the build for this project. When i run the build from the command prompt it actually builds without errors, but when i run it with CruiseControl.net i get the following error:

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()

The user is getting a 500 internal error occurred. What he is trying to do is create a datagrid. The error only happens when there are a lot of data used to build the grid. But why exactly is it too much data? And can I increase a buffer or set something in a config file to allow all the data? The data come from a web service.

I wanted to post my problem and solution since I've gotten some good information on this board. When deploying my Visual Studio 2008 C# .NET 2.0 web application Production, I encountered some problems, which is not unusual. What was unusual is that my Crystal Reports .NET reports that use the Report Viewer control would not work; they errored out with:
note: Crystal Report works fine in dev environment....
Logon failed. Details: ADO Error Code: 0x Source: ADODB.Connection Description: Provider cannot be found. It may not be properly installed. Unable to connect: incorrect log on parameters.We are using Oracle 11g 64 bit as database. We establish crystal report database connection by two ways,

but we got the same error in report module when we using two methods.

I know that you can use exclamation sign to bind array of simple types (like string) to GridView like this
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false">
<Columns>
<asp:BoundField HeaderText="Array Field" DataField="!" />
</Columns>
</asp:GridView>
But this doesn't seem to be the case with DataNavigateUrlFields
<asp:HyperLinkField DataNavigateUrlFields="!" DataNavigateUrlFormatString="RoleInformation.aspx?role={0}" Text="Manage users" />
and I get following error:A field or property with the name '!' was not found on the selected data source.

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.
