I have a web application that has worked until today.
My dataset stopped working for some reason.  Here is the line of code from my data access component:

daParent_AnalystJobs.Fill(dSet)

This is the stack trace:
[ArgumentNullException: Value cannot be null.
Parameter name: dataSet]
   System.Data.Common.DbDataAdapter.Fill(DataSet dataSet, Int32 startRecord, Int32 maxRecords, String srcTable, IDbCommand command, CommandBehavior behavior) +103
   System.Data.Common.DbDataAdapter.Fill(DataSet dataSet) +38
   Analyst_In_Time.data.FillDataSet(dsAnalystJobs dSet) in C:\Inetpub\wwwroot\Analyst_In_Time\data.vb:463
   Analyst_In_Time.Admin.RefreshDatabindings() in C:\Inetpub\wwwroot\Analyst_In_Time\Admin.aspx.vb:66
   Analyst_In_Time.Admin.Page_Load(Object sender, EventArgs e) in C:\Inetpub\wwwroot\Analyst_In_Time\Admin.aspx.vb:56
   System.Web.UI.Control.OnLoad(EventArgs e) +67
   System.Web.UI.Control.LoadRecursive() +29
   System.Web.UI.Page.ProcessRequestMain() +724


This was working fine yesterday.  I've done a release configuration on the project.  

Does anyone know what might have happened?

Hi,

How are you instantiating the dataset object?

Hint: Create a new instance of the dataset before
you call to fill it.

The issue was related to instantiation of the dataset.  Somehow, the dataset control disappeared from the component tray of the form.  Also, I could not regenerate it in Visual Studio 2002.  This appears to be a bug in Visual Studio 2002.  Hopefully, it is fixed as I installed the Service Pack 1.  Thanks for your reply.
