Hello,

Using VB.net in VS2010.

I have a Main form and then a Reports form.  This Reports form has a ReportViewer, called rptExpenses.  When I load the Reports form, the following code runs:
Private Sub frmReports_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Dim SQLText As String = "SELECT * FROM expenses"
        Dim SQLData As DataTable = DBGetTable(SQLText)
        Me.rptExpenses.LocalReport.DataSources.Clear()
        Dim rprtDTSource As Microsoft.Reporting.WinForms.ReportDataSource = New Microsoft.Reporting.WinForms.ReportDataSource(SQLData.TableName, SQLData)
        Me.rptExpenses.LocalReport.DataSources.Add(rprtDTSource)
        Me.rptExpenses.LocalReport.ReportPath = "C:\Users\Jason\Documents\Visual Studio 2010\Projects\Remote-Expense\Remote-Expense\Report1.rdlc"
        Me.rptExpenses.RefreshReport()
    End Sub

Open in new window

Here's the problem: Everything works fine, however, when I exit the entire application (not the Reports form), I get the following error:

Error while unloading appdomain. (Exception from HRESULT: 0x80131015)
Screenshot:Error while unloading appdomain. (Exception from HRESULT: 0x80131015)Commenting out this one line removes the error:
Me.rptExpenses.LocalReport.ReportPath = "C:\Users\Jason\Documents\Visual Studio 2010\Projects\Remote-Expense\Remote-Expense\Report1.rdlc"

Open in new window

[u]Questions:[/u]
What am I doing wrong?
And how can I fix it?


Thanks!
