style2.SetFont(font1);

style2.TopBorderColor = NPOI.HSSF.Util.HSSFColor.Black.Index;
style2.Alignment = HorizontalAlignment.Left;
style2.WrapText = true;

return style2;
}
```
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!

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,

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.

Hello,

Is there possible to know the export progress state, in order to display a progress bar for time consuming excel export operations (large files combined with AutoFit) ?
And also is it possible to Cancel a started Excel export operation?

Currently I don't find any other way then displaying a marquee progress bar w/o a Cancel button.

Thanks,
Bogdan

≪ Previous: Reviewed: NPOI 2.1.1 (7月 28, 2014)

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.
