Body
copied!<p>I have a messaging application set up in C# and will add the messages received asynchronously into a list. I am using only the Microsoft.Office.Interop.Excel namespace and not VSTO extensions thus faces a problem with the listobject.</p> <p>What I want to do is to create a listobject using the method below and use a timer object to write to excel spreadsheet.</p> <pre><code>public static ListObject AddListObject() { oXL = (Excel.Application)System.Runtime.InteropServices.Marshal.GetActiveObject("Excel.Application"); oWB = oXL.Workbooks.get_Item(1); oSheet = (Excel.Worksheet)oWB.ActiveSheet; activeRow = oXL.ActiveCell.Row; //content oSheet.Cells[activeRow , 1] = Store[0].name; oSheet.Cells[activeRow , 2] = Store[0].address; oSheet.Cells[activeRow , 3] = Store[0].number; oSheet.Cells[activeRow , 4] = Store[0].dob; Excel.ListObject listObject1 = oSheet.ListObjects.Add( Excel.XlListObjectSourceType.xlSrcRange, oXL.ActiveCell.CurrentRegion, false, Microsoft.Office.Interop.Excel.XlYesNoGuess.xlNo, Type.Missing); listObject1.TableStyle = "TableStyleLight9"; oXL.Visible = true; oXL.UserControl = false; return listObject1; } </code></pre> <p>In the main program, after starting the messaging portion, I will get the listobject and pass it to the timer to update the spreadsheet.</p> <pre><code>listobject1 = AddListObject(); timer = new Timer(DoSomething, listobject1, 0, 1000); </code></pre> <p>How do I do that when the timer object calls the DoSomething method every second?</p> <pre><code>public void DoSomething(ListObject obj) { //refresh listobject and write and update to spreadsheet every second } </code></pre> <p>In VSTO, I will do the following:</p> <pre><code>listobject1 = AddListObject(); listobject1.DataSource=Store; listobject1.AutSetDataBoundColumnHeaders=true; timer = new Timer(DoSomething, listobject1, 0, 1000); public void DoSomething(object state) { //refresh listobject and write and update to spreadsheet every second ListObject lbo = (ListObject)state; lbo.RefreshDataRows(); } </code></pre> <p>How do I do the following without VSTO extensions?</p>
