New Post: Upgrading NPOI. Need Help.

Windows Server 2008 R2. IIS 7. Visual Studio 2012.

I am using a older version of NPOI. But I am not sure what version or how to tell. However, my current (old) version has there files in my Bin folder:

NPOI.DDF.dll
NPOI.dll
NPOI.HPSF.dll
NPOI.HSSF.dll
NPOI.POIFS.dll
NPOI.Util.dll

Version 2.0 has the files:

ICSharpCode.SharpZipLib.dll
NPOI.dll
NPOI.OOXML.dll
NPOI.OOXML.XML
NPOI.OpenXml4Net.dll
NPOI.OpenXml4Net.XML
NPOI.OpenXmlFormats.dll
NPOI.XML

Do I just replace the old files with these?

Second question. In my VBA code I have:

'Libraries needed for the NPOI Excel worksheet creation
Imports NPOI.HSSF.UserModel
Imports NPOI.HSSF.UserModel.HSSFCellStyle
Imports NPOI.HPSF
Imports NPOI.HSSF.Util
Imports NPOI.POIFS.FileSystem

What do I replace these with using the new version of NPOI?

Is there anything else I need to do to utilize the new version and to remove the old version from my web site?

Thanks for the help.

Hello, I have an application that fills with data an excel template .Template has .xlsm format .In template I created vba function called SumByColor when i try to set a cell formula to this function i get :
{"Name 'SumByColor' is completely unknown in the current workbook"}
I set formula like this :
```
sheet.GetRow(rowIndex).GetCell(startPos + 2).SetCellFormula(string.Format("SumByColor($AQ$7,F{0}:AI{0})",rowIndex+1));

Commented Unassigned: Buffer overrun while writing a workbook [13159]

Hi,

I'm trying to write an excel using filestream
```
using (FileStream file = new FileStream(selectDest.SelectedPath + @"\Import update LHT.xls", FileMode.Create, FileAccess.Write))
{
wbImport.Write(file);
}
```
and I'm getting this error
```
An unhandled exception of type 'NPOI.Util.RuntimeException' occurred in NPOI.dll

Additional information: Buffer overrun i=111;endIndex=152;writeIndex=43
```

The workbook has only one sheet with about 500 rows so I don't think the size is the problem.

The workbook writing worked until last week and since I keep getting this error and I don't know why.
Comments: ** Comment from web user: tonyqus **

The error is thrown by LittleEndianByteArrayOutputStream class

private void CheckPosition(int i)
{
if (i > _endIndex - _writeIndex)
{
throw new RuntimeException(string.Format(CultureInfo.InvariantCulture, "Buffer overrun i={0};endIndex={1};writeIndex={2}", i, _endIndex, _writeIndex));
}
}

If it used to work, the issue may be caused by the original xls template. I need your complete code and xls file to check what's going on.

I found that if it is set style by the NOPI DLL, the template Excel style will be lost. If I do not implement the "getWhiteText" function, it will not be lost.

Please help me! thanks!

Edited Issue: SetSheetOrder breaks XLSX [13142]

August 2, 2014, 6:50 pm
$
0
0
NPOI 2.1
XSSFWorkbook.cs

Issue:
When setting the sheet order (i.e. moving a worksheet) with XSSF, the XLSX file will break and cannot be opened with Excel.

Reason:
CT_Sheet.Set will set the SheetId of the moved sheet to 0, which the OpenXML format does not allow.

our workaround:
keep the sheetId
```
public void SetSheetOrder(String sheetname, int pos)
{
int idx = GetSheetIndex(sheetname);
XSSFSheet sheet = sheets[idx];
sheets.RemoveAt(idx);
sheets.Insert(pos,sheet);
// Reorder CT_Sheets
CT_Sheets ct = workbook.sheets;
CT_Sheet cts = ct.GetSheetArray(idx).Copy();

// get sheetid from sheet to be moved
uint Mysheetid = ct.GetSheetArray(idx).sheetId;

workbook.sheets.RemoveSheet(idx);
CT_Sheet newcts = ct.InsertNewSheet(pos);
newcts.Set(cts);

// retrieve sheetid
newcts.sheetId = Mysheetid;

//notify sheets
for (int i = 0; i < sheets.Count; i++)
{
sheets[i].sheet = ct.GetSheetArray(i);
}
}
```

Hi,

You are right, the issue is the xls file because it was created badly as an export from another application.

Created Issue: Adding more than one chart to worksheet results in corrupt .XLSX file [13181]

I am trying to create an Excel worksheet containing multiple charts. However, when I add a second chart the resulting .XLSX file is corrupt when I try opening it.

Here is a code sample that shows the issue (modified from the LineChart example):

```
static void Main(string[] args)
{
int NUM_OF_CHARTS = 2;

IWorkbook wb = new XSSFWorkbook();
ISheet sheet = wb.CreateSheet("linechart");

IDrawing drawing = sheet.CreateDrawingPatriarch();

for (int i = 0; i < NUM_OF_CHARTS; i++)
{
CreateChart(sheet, drawing, i);
}

using (FileStream fs = File.Create(String.Format("test-{0} charts-{1}.xlsx", NUM_OF_CHARTS, DateTime.Now.Ticks)))
{
wb.Write(fs);
}
}

static IChart CreateChart(ISheet sheet, IDrawing drawing, int factor)
{
int NUM_OF_ROWS = 3;
int NUM_OF_COLUMNS = 10;

Random r = new Random((int)DateTime.Now.Ticks);

System.Threading.Thread.Sleep(r.Next(50, 100));

// Create a row and put some cells in it. Rows are 0 based.
IRow row;
ICell cell;
for (int rowIndex = 0 + (NUM_OF_ROWS * factor); rowIndex < NUM_OF_ROWS * (1 + factor); rowIndex++)
{
row = sheet.CreateRow((short)rowIndex);
for (int colIndex = 0; colIndex < NUM_OF_COLUMNS; colIndex++)
{
cell = row.CreateCell((short)colIndex);
if (rowIndex == 0 + NUM_OF_ROWS * factor)
{
cell.SetCellValue(colIndex);
}
else
{
cell.SetCellValue(r.Next(0,100));
}
}
}

IClientAnchor anchor = drawing.CreateAnchor(0, 0, 0, 0, 10, 0 + (10 * factor), 20, 10 + (10 * factor));

IChart chart = drawing.CreateChart(anchor);
ILineChartData<double, double> data = chart.GetChartDataFactory().CreateLineChartData<double, double>();

// Use a category axis for the bottom axis.
IChartAxis bottomAxis = chart.GetChartAxisFactory().CreateCategoryAxis(AxisPosition.Bottom);
IValueAxis leftAxis = chart.GetChartAxisFactory().CreateValueAxis(AxisPosition.Left);

IChartDataSource<double> xs = DataSources.FromNumericCellRange(sheet, new CellRangeAddress(0 + factor * NUM_OF_ROWS, 0 + factor * NUM_OF_ROWS, 0, NUM_OF_COLUMNS - 1));
IChartDataSource<double> ys1 = DataSources.FromNumericCellRange(sheet, new CellRangeAddress(1 + factor * NUM_OF_ROWS, 1 + factor * NUM_OF_ROWS, 0, NUM_OF_COLUMNS - 1));
IChartDataSource<double> ys2 = DataSources.FromNumericCellRange(sheet, new CellRangeAddress(2 + factor * NUM_OF_ROWS, 2 + factor * NUM_OF_ROWS, 0, NUM_OF_COLUMNS - 1));

var s1 = data.AddSerie(xs, ys1);
s1.SetTitle("title1");
var s2 = data.AddSerie(xs, ys2);
s2.SetTitle("title2");

chart.Plot(data, bottomAxis, leftAxis);

return chart;
}
```




Any ideas?

Commented Issue: [Bug] Broken named ranges after existing file modification [13165]

August 8, 2014, 2:11 am
$
0
0
I tried to open existing xlsx file (from excel 2007) and alter named ranges (can be specified in excel in Formulas/Name manager).

Problem is that when file is saved, all names' scope is changed to Sheet instead of whole Workbook. It breaks existing expressions.

Primary issue seems to be in CT_DefinedName class, Parse method is setting fields
ctObj.localSheetId = XmlHelper.ReadUInt(node.Attributes["localSheetId"]);
ctObj.localSheetIdFieldSpecified = node.Attributes["localSheetId"] != null;

while Write method always set localSheedId even if it was not originally present - it causes that field is set to 0 and scope is set to 1st sheet instead of workbook. There should be some check if localSheetIdFieldSpecified is set.
XmlHelper.WriteAttribute(sw, "localSheetId", this.localSheetId, true);


Btw, another bug is that expression "=SHEET_NAME!defined_name" cannot be parsed by NPOI, it fails with error that reference is expected. Expression "=defined_name" works but I cannot use it as it works with global scope names only.

Hi, I'm using the NPOI 2.0 Version of your library, and I'm having an issue when creating an Excel file and try to open with Microsoft Excel 2013.

There is a column with date format, that works fine from row 1 to 10, but from row 11 the program stops reading this property and shows a weird decima value.

The llibrary works perfect for me in older versions of Excel, OpenOffice and GoogleDrive.

I attach a screenshot.

Thanks and regards!

I'm experiencing the same sort of problems..

I generate a file and if I open this file in Excel 2010, everything looks fine, just the way I want it, and if someone runs the program and opens the generated file in Excel 2010, the table looks fine from row 1 to 10, after row 10 the style isn't applied anymore.

Comments: ** Comment from web user: applepie89 **

for additional information, I use this code to apply the style:

First I Defined the style I want to apply:
```
HSSFFont fontStyleSubject = (HSSFFont)xlsWorkbook.CreateFont();
fontStyleSubject.Boldweight = (short)FontBoldWeight.BOLD;
ICellStyle cellStyleSubject = xlsWorkbook.CreateCellStyle();
cellStyleSubject.SetFont(fontStyleSubject);
short colorIndex = new HSSFColor.GREY_25_PERCENT().GetIndex();
cellStyleSubject.FillForegroundColor = colorIndex;
cellStyleSubject.FillPattern = FillPatternType.SOLID_FOREGROUND;
```

after that, I have the following:
```
if (cellIsHeader)
{
wbCell.SetCellValue(cellValue);
wbCell.CellStyle = cellStyleSubject;
}
```

the strange thing is, as you can see in the attachment (difference), I also have a borderstyle, and this behaves correctly on all the rows as you can see, the code for this is nothing more then:

defining the style:
```
ICellStyle borderStyle = xlsWorkbook.CreateCellStyle();
borderStyle.BorderBottom = BorderStyle.THIN;
borderStyle.BorderRight = BorderStyle.THIN;
```

and if none of the if/else if's apply on a row, this code is applied:
else
```
{
wbCell.CellStyle = borderStyle;
}
```

Created Unassigned: Missing Rows in XSSFWorkbook [13193]

August 11, 2014, 9:19 am

I'm using npoi 2.0.6.0 with .net 4.5.

I'm trying to load and parse a spreadsheet that is publicly available on the internet on the web page http://www.directedge.com/MarketData/SecuritiesTraded.aspx .

The file is the "EDGA Securities Traded" - I've attached the original spreadsheet and another spreadsheet that indicates the missing rows. This spreadsheet is liable to change every day, but the direct download link is http://www.directedge.com/Portals/0/02Market%20Data/Securities%20Traded/EDGA%20-%20Tradable%20Symbols.xlsx

I load the spreadsheet like this:

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(Url); // Same as displayed above
HttpWebResponse response = (HttpWebResponse)request.GetResponse();

using (Stream ResponseStream = response.GetResponseStream())
{
IWorkbook workbook = new XSSFWorkbook(OPCPackage.Open(ResponseStream));

Then, I iterate through the rows:

for (int RowNumber = sheet.FirstRowNum; RowNumber <= sheet.LastRowNum; RowNumber++)
{

This is where the weirdness starts. When the attached spreadsheet is loaded into Excel, the first row is 1 and the last row is 8156 which is 8155 rows. However, in NPOI, the FirstRowNum=0 and the LastRowNum=8147 which is 8148 rows. So seven rows are missing. I've determined the missing rows are:

RowNum Column A Column B
[3393] HIH HELIOS HIGH INCOME FUND INC
[3421] HMH HELIOS MULTI-SECTOR HI INCM FD
[3480] HSA HELIOS STRATEGIC INCOME FUND
[4542] MCLB MICROLIN BIO, INC
[4543] MCLBW MICROLIN BIO, INC
[4898] MTY CITIGROUP FDG INC 8/11/14
[4909] MUK CITIGROUP FDG INC 8/11/14

Can someone tell me why they appear to be missing?
