Working with PowerPoint chart data not working anymore
New problem after latest MS Office update

Hi

Using the latest MS Office 365 Update (version 2003), closing the workbook containing the chart data of a PowerPoint chart fails with error 0x800A03EC. I have also seen this happening in the newest 2016 version. Closing the window instead of the workbook fails as well. Here some simplified code to recreate the issue:

try
{
PowerPoint.Chart ppChart = ppShape.Chart;
PowerPoint.ChartData cdata = ppChart.ChartData;
cdata.Activate();
Excel.Workbook xlsWorkbook = (Excel.Workbook)cdata.Workbook;

// update the chart data

xlsWorkbook.Close();
}
catch (Exception ex)
{
MessageBox.Show(ex.ToString());
}

Can you confirm this is a bug in the new update? If yes, where do I report the issue?

Do you have a work-around, so I can close the workbook in some other way?

Thanks in advance!

Regards
Fred

Hello Fred,

Make sure that "// update the chart data " also includes releasing all COM objects, including the chart. For a test, you can choose to not do the update thus not creating COM objects.

Also, make sure there's no COM add-ins in Excel. If your add-in is laoded in Excel as well, make sure it detects this scenario by checking ExcelApp.UserControl which is false in this case: the add-in may not show the UI and not react to events in this case.

Hello Andrei,

Thank you for the fast reply!

I did test doing nothing (not updating any chart data - no COM object created), and it still fails. I have deactivated my add-in in Excel, which does not help either.

Using Office 365 version 2002 and all older versions are working fine. I (and unfortunately some of my customers as well) only have this issue using the latest update.

Regards
Fred

Hello Fred,

Please send me a sample project and sample presentation. I'll check the code and test it on my side. Find the support email address in {Add-in Express installation folder}\readme.txt. Make sure your email contains a link to this topic.

Thank you, Fred.

The code produces this error:

---------------------------

---------------------------
System.Runtime.InteropServices.COMException (0x800A03EC): Exception from HRESULT: 0x800A03EC

   at Microsoft.Office.Interop.Excel._Workbook.Close(Object SaveChanges, Object Filename, Object RouteWorkbook)

   at OpenCloseChart.AddinModule.adxRibbonButton1_OnClick(Object sender, IRibbonControl control, Boolean pressed) in E:_Projects_testsFred Balkenende‚0_04_15 14_33OpenCloseChartAddinModule.cs:line 113
---------------------------
OK   
---------------------------


I believe 0x800A03EC relates to Excel being not focused or never focused. To check this, use two buttons: #1 opens that workbook, #2 closes it. Before clicking #2, click the workbook to activate it. If it works in this scenario, you would need to use the machinery we describe in section Wait a Little; see the PDF file in the folder {Add-in Express}\Docs on your development PC. You should focus the workbook window first: use the Excel object model or Windows API to do this. Once that call is done, you send a message (integer > 1024); then the OnSendMesage fires, you filter out that message and close the workbook.

Hi Andrei

Even though it never has been necessary to give the chart data window focus (our solution has been working for many years), I have tried using the 2 buttons. It does not work. After opening, I move the Excel window around, but still get the same error on 'Workbook.Close()' when clicking the second button.

As I see it, the newest version always fails when calling 'workbook.Close()' when trying to close the Excel data window.

Any other suggestions?

Thanks
Fred

Hello Fred,

This looks like a bug in that Excel version. What Excel build are you using? I can create a post on the Excel for Developers forum to let someone know about the issue.

Hi Andrei

It is only happening in the newest versions of Office. I am using the monthly update for Office 365, version 2003 12624.20442. I just updated to version 2003 12624.20466 which was released yesterday. The error is still there.

Thanks!
Fred
