Hi,

I have recently upgraded from 0.65 to 0.73 and while I have seen some performance improvements, several reports that run in parallel threads crashed in my UAT environment. It seems the problem is in the AdjustToContents() method.

The full exception is:

Commented Issue: "Unreadable content" when editing and reopening generated file in Excel 2010 [8466]

August 2, 2014, 8:03 pm

The problem is described in the discussions in the following thread: http://closedxml.codeplex.com/discussions/403797
When I open an existing Excel file using ClosedXml and save it (even without performing any actions), the file gets corrupted when it is edited using Excel 2010 afterwards. Excel 2007 and Excel 2013 do not produce the problem on my Systems (tested with WinXP and Win8).
I've attached the following small sample program:

```
namespace ClosedXml_Template_Test
{
using System.IO;
using ClosedXML.Excel;
class Program
{
static void Main(string[] args)
{
string inFilepath = "Template.xlsx";
string outFilepath = "Generated.xlsx";
byte[] fileContent;
using (FileStream fileStream = File.OpenRead(inFilepath))
{
// Read from file
fileContent = new byte[fileStream.Length];
fileStream.Read(fileContent, 0, fileContent.Length);
}
using (MemoryStream memStream = new MemoryStream())
{
// Write to MemoryStream
memStream.Write(fileContent, 0, fileContent.Length);
// Create ClosedXml instances
using (XLWorkbook workbook = new XLWorkbook(memStream, XLEventTracking.Disabled))
{
// Save the workbook to the stream
workbook.Save();
}
// Get the content from the stream
fileContent = memStream.ToArray();
}
if (File.Exists(outFilepath))
{
// Delete existing generated file
File.Delete(outFilepath);
}
using (FileStream fileStream = File.OpenWrite(outFilepath))
{
// Save the new file
fileStream.Write(fileContent, 0, fileContent.Length);
}
}
}
}
```

EDIT: Reformatted the post (CodePlex somehow killed the layout...)
Comments: I would like to look into this, but I am unable to reproduce the issue on my machine. Can you tell me what versions off Excel/Office you are using, and if the issue still happens for you.

If a excel File has no WorkbookProperties defined the document load fails.

ClosedXML.Excel.XLWorkbook_Load.cs

var date1904 = dSpreadsheet.WorkbookPart.Workbook.WorkbookProperties.Date1904;

It raise "Object reference not set to an instance of an object"

Commented Unassigned: Bug if worksheet name contains ' character [9220]

August 2, 2014, 8:16 pm
$

0
If a a worksheet name contains one or more apostroph characters (') and if a print area is defined for that worksheet, then __new XLWorkbook("mybook.xlsx")__ fails.

The problem is in XLWorkbook_Load.cs

```
private static void ParseReference(string item, out string sheetName, out string sheetArea)
{
var sections = item.Trim().Split('!');

// If the worksheet name is "D'Artagnan" (encoded as 'D''Artagnan')
// *all* apostrophs will get stripped and we get "DArtagnan" instead of "D'Artagnan"
sheetName = sections[0].Replace("\'", "");
sheetArea = sections[1];
}
```

This will lead to an exception later in the XLWorksheets.Worksheet method.

The attached xlsx file exposes the bug.
Comments: The proposed fix causes corrupt output with Excel 2010 on my machine.

Both V7 and W7 cell values are blank, but excel handles this scenario by evaluating MAX to 0.0.

Excellent, thanks for that. Are there any plans for a new release (i.e. 0.74)?

And how about password protected workbook protection, is it being worked on, or are there no current plans to do so?

Thanks again!

New Post: Pivot table "Value Field Settings"

Hey there.

I've been trying to use ClosedXML to generate a group of Excel files systematically.

One of the tabs contains a Pivot Table that I was already able to add but I can't find a way to set the fields to "Show values as % of Column Total", this is an option that can be selected by going to "Options -> Show Values As" when the Pivot Table is selected.

Is it possible to do this with ClosedXML?

Thank you for your help and for the great tool you have developed!
