    <p>at the moment I have a small application and need to take information from an object and display it into an excel file, using the Microsoft.office.interop class I've been able to write to the file, and it shows one by one the records being added, however about once every 3 times I try it, the spreadsheet stops filling somewhere between the 300th and 600th record, I have 6,000 in total and it's not breaking every time, I put a check after it finishes to see whether the last record is filled in but the code never reaches that point and I'm unsure of what's happening</p> <p>I also don't know how to debug the problem as it'd mean going through 6,000 loops to check for it stopping... which might not even happen?</p> <p>a little section of the code is here</p> <pre><code>loadExcel(incidents, WorkSheetName) If WorkSheetName.Cells(DBObject.HighestInci + 1, 6) Is Nothing Then MessageBox.Show("Failed to fill spreadsheet, Retrying now.") loadExcel(incidents, WorkSheetName) End If </code></pre> <p>above is the code calling and checking the method below</p> <pre><code>Private Sub loadExcel(ByVal incidents As List(Of Incident), ByRef WorkSheetName As Excel.Worksheet) Dim i = 2 For Each inc As Incident In incidents WorkSheetName.Cells(i, 1) = inc.DateLogged WorkSheetName.Cells(i, 2) = inc.DateClosed WorkSheetName.Cells(i, 3) = Convert.ToString(inc.DateLogged).Substring(3, 2) i += 1 Next End Sub </code></pre> <p>Thanks in advance</p> <p><em>EDIT</em> </p> <p>I'm thinking loading it to a buffer of some sort then writing once they have all been updated would be the way to go instead of it currently loading and writing each separately? however I have no idea where to start for that?</p>

    1. COHave you checked your input data? Something wrong in `inc` var could be the potential source of the problem. Add a System.Diagnostics.Debug.Writeline(....) inside the incidents loop.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
