You did something wrong. I have no idea why you got this wired issue. This must not be a bug.

I receive an 'error evaluating cell' message when running the EvaluateAllFormulaCells method on an xls that has a cell with the present value function PV. i do not receive the error on any other formulas.

Please see my code below and let me know if any ideas. Thanks!

HSSFWorkbook xssfwb;
using (FileStream file = new FileStream(@"c:\Book1.xls", FileMode.Open, FileAccess.ReadWrite))
{
xssfwb = new HSSFWorkbook(file);
HSSFFormulaEvaluator.EvaluateAllFormulaCells(xssfwb);

Please make sure that you open with the correct namespace. For xls, you must use HSSF. For xlsx, you must use XSSF. The error occurs because you are trying to open xlsx with HSSFWorkbook. Instead, XSSFWorkbook should be used.

<p>Even if you set the value of scale in Print Setup object, it doesn&#39;t work in Excel 2007/2010. The radiobox of scale is no selected as expected.</p>

It looks a bin file of PrintSetup is not generated correctly in the current version of POI as well as NPOI. I'll try to fix it. This is confirmed as a bug

NPOI 2.0 alpha

When using XSSH and invoking CreateDrawingPatriarch() on a sheet only the first call will return an IDrawing object. Subsequent calls will return null.

Sample Code:

private static void SetCellComment(ISheet worksheet, int columnPosition, int rowPosition, string comment)
{
//Get row
var row = worksheet.GetRow(rowPosition) ?? worksheet.CreateRow(rowPosition);

//Get or Create Cell
var cell = row.GetCell(columnPosition) ?? row.CreateCell(columnPosition);

//We need a drawing patriarch as a graphics surface.
var drawingSurface = worksheet.CreateDrawingPatriarch();

//The creation helper can provide objects.
var objectFactory = worksheet.Workbook.GetCreationHelper();

//We need a graphics anchor.
var anchor = objectFactory.CreateClientAnchor();

//Create the new comment.
var newComment = drawingSurface.CreateCellComment(anchor);
newComment.String = objectFactory.CreateRichTextString(comment);

//Link the comment to the desired cell.
cell.CellComment = newComment;

Hello, is there any particular reason to have this 'design'? For some users, this looks like a constraint anyway.
Thanks for your great work.

This is my code...

using namespace NPOI::HSSF::UserModel;
using namespace NPOI::XSSF::UserModel;
using namespace NPOI::SS::UserModel;
using namespace NPOI::OpenXmlFormats;
...
IWorkbook^ book;
book = gcnew XSSFWorkbook(stream);

And I have all the DLLs referenced including NPOI.OpenXmlFormats.dll, I tried with the Alpha 2.0 release. My project is being compiled with .Net 3.5 using Visual C++ Express version.... as reference, I tried other library and also complains with the XML libraries (not using this one) so, there may be an issue with some XML patch or security setting....

When I try to list all members in the NPOI.OpenXmlFormats.dll I only see the namespaces:
Vml
Wordprocessing
Noting like XmlSerializers... as if this namespace or class were not included in the library...

Regards...

Commented Issue: NPOI 2.0 Unable to Export 70k Rows [11160]

<p>Hi,</p>
<p>&nbsp;</p>
<p>I am using NPOI 2.0 Alpha to export data from a work system as we wanted to get round the Excel 97-2003 65K row limitation. </p>
<p>&nbsp;</p>
<p>I have implemented it today but it seems to be unable to export 70k rows and falls over with an OutOfMemory exception.</p>
<p>&nbsp;</p>
<p>The file is only 70k rows by around 20/25 columns of text - no formatting is present.</p>
<p>&nbsp;</p>
<p>I understand XML requires large amounts of memory but the limitation doesn&#39;t seem to be down to my machine (it has plenty of RAM spare), instead it seems to be down to one of the internal structures that NPOI is using (memory stream or byte array perhaps?).</p>
<p>&nbsp;</p>
<p>I have attached a stack trace to demonstrate.</p>
<p>&nbsp;</p>
<p>Could someone advise if there is a way round this? Alternatively, where can i find the NPOI 2.0 source code for download so i can step through and try and find a solution myself?</p>
<p>&nbsp;</p>
<p>If this can be solved it&#39;d be a real bonus as this will likely be a common problem.</p>
<p>&nbsp;</p>
<p>&nbsp;</p>
<p>Thanks in advance,</p>
<p>&nbsp;</p>
<p>u33db</p>

Comments: ** Comment from web user: tonyqus **

No workaround for now. We will try to optimize this issue in NPOI 2.1 or later version.
