Here's my code:
var comment = xlSheet.Cells[iDataRow, iCol].AddComment(sb4info.ToString(), "Dean");

After that, I opened the excel file. And then there's an error msg:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<recoveryLog xmlns="http://schemas.openxmlformats.org/spreadsheetml/2006/main"><logFileName>error082960_01.xml</logFileName><summary>Errors were detected in file 'C:\AAAAAAA\CDS\TestLDSS\CDS_LDSS_V_2.2.1ALL.xlsx'</summary><repairedRecords summary="Following is a list of repairs:"><repairedRecord>Repaired Records: Comments from /xl/comments2.xml part (Comments)</repairedRecord></repairedRecords></recoveryLog>

When I use a stored procedure to fetch data into a data set table containing a formula in one column and load the data into excel file from a specified row using LoadFromDataTable method, the formula column displays just the formula and not the value calculated using the formula. What settings I need to use for the cell to display the value using the formula in that column which is fetched from the stored procedure ???

Created Unassigned: ExcelPackage Write + System.OutOfMemoryException [14942]

Hi,

We have been using EPPlus version 3.1.3.0 successfully quite for some time now. Thank you for this wonderful functionality. We used to have a 64 bit Win XP machine with a 8 GB RAM. It was indeed very satisfactory at that point. But now we are limited with 32 bit Win 7 machine with 3.39 GB usable RAM.
This limitation has also affected our tool functionality as well. We are getting the following error for quite some time now.

Exception Details : System.OutOfMemoryException: Exception of type 'System.OutOfMemoryException' was thrown.

While we check the file we found despite raising the error the file has been filled with all the records properly. ( approx 10 Lacs + record).

We have also monitored the program execution and found out that this error comes while it reads from c:\pagefile.sys and writes to the concerned excel file <filepath>.

Memory consumed during this time is almost full. ( only 6-100 MB is Free). We are very much limited with the Memory increment ( from 4 gb to 8 gb and 32 bit to going back to 64 bit again ). Could you please suggest if there is any other way to resolve this issue.

I have mentioned below the code we are using,

Calling Block :

try
{
Writer objWriter = new Writer();
objWriter.exportExcel(dataDump, full_file_name);

dataDump.Clear();
dataDump.Reset();
}
catch (Exception ex)
{
dataDump.Clear();
dataDump.Reset();
string logfileName = dr["SHEET_NAME"].ToString() + "_error.log";
StreamWriter logwriter = new StreamWriter(Path.Combine(foln, logfileName));
logwriter.Write(ex.ToString());
logwriter.Close();
}
finally {

dataDump.Clear();
dataDump.Reset();
}

The currently targeted framework ".NETFramework,Version=v4.0,Profile=Client" does not include "System.Web, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" which the referenced assembly "EPPlus" depends on. This caused the referenced assembly to not resolve. To fix this, either (1) change the targeted framework for this project, or (2) remove the referenced assembly from the project.

Created Unassigned: Cannot save Excel sheet when using VLOOPUP formula [14945]

When using VLOOPUP formula when you open the generated Excel and try to save it you get the error message [One or more formulas in the workbook are longer that the allowed limit of 8192 characters. If you press F2 then Enter on the formula then apply this to the whole column you are then able to save.

Code used to create the formula in the table:
sheet.Cells[string.Format("P2:P{0}", sheet.Dimension.End.Row)].Formula = "VLOOKUP(E2,'Tag Link'!E:E,1,FALSE)";

Commented Unassigned: Changing any row height after inserting picture makes it square [14846]

After inserting picture I change some other row's height. The result is that picture is square. If I comment out row's height change, picture is rectangular as expected.

Image position and size does not have any impact on that issue. It does not have to be positioned in the row with changed height.

```
static void Main(string[] args)
{
var targetPath = Path.Combine(Path.GetTempPath(), Path.ChangeExtension(Path.GetRandomFileName(), ".xlsx"));

using (var package = new ExcelPackage())
{
var worksheet = package.Workbook.Worksheets.Add("new");

var image = new Bitmap(150, 50);
using(var g = Graphics.FromImage(image)) g.FillRectangle(Brushes.Black, 0, 0, 149, 49);

var picture = worksheet.Drawings.AddPicture("Picture", image);
worksheet.Row(1).Height = 5;

package.SaveAs(new FileInfo(targetPath));
}

Process.Start(targetPath);
}
```
Comments: I think we only need modify drawing code https://github.com/ylatuya/EPPlus/blob/master/EPPlus/Drawing/ExcelDrawings.cs maybe new constructor or new parameter inside ```AddPicture``` method to accept pictures as oneCellAnchor ```<xdr:oneCellAnchor editAs="oneCell">``` and compute related ext values here: ```<xdr:ext cx="3857625" cy="1047750" />```

Created Unassigned: Supplied properties in parameter Properties must be of the same type as T [14946]

First of all I'd like to thank you for this great plugin.

In the following method,

public ExcelRangeBase LoadFromCollection<T>(IEnumerable<T> Collection, bool PrintHeaders, TableStyles TableStyle, BindingFlags memberFlags, MemberInfo[] Members)

Then following code is throwing an exception, when I pass a dynamic object T with known MemberInfos.

var type = typeof(T);
if (Members == null)
{
Members = type.GetProperties(memberFlags);
}
else
{
foreach (var t in Members)
{
if (t.DeclaringType != type)
{
throw (new Exception("Supplied properties in parameter Properties must be of the same type as T"));
}
}
}

Currently I have commented this code and importing the whole source code in my solution. If the 'else' part is commented out is commented out all is working well.

Do you think you could comment the else part and update the nuget? if not why do you have to check the types of individual properties? This would not allow dynamic objects to be passed using dynamic keyword.

Please let me know.

Thank you.

Created Unassigned: XmlException on loading some xlsx files. [14948]

February 18, 2014, 8:09 am

If we load xlsx file created by some accounting software, access to Workbook.Worksheets lead to XmlException: Unexpected XML declaration. The XML declaration must be the first node in the document, and no white space characters are allowed to appear before it. Line 49, position 16.

One reason is that xml files created by this applications are formatted (with tabs and newlines).
In Worksheet.cs we have set of Load functions (LoadCells(xr);, etc.) whict are not expecting any whitespace.
For example, in LoadColumns we have following peace of code:
```
if (ReadUntil(xr, "cols", "sheetData"))
{
while(xr.Read())
{
if (xr.LocalName != "col") break;
if (xr.NodeType == XmlNodeType.Element)
```

This will not work if we have whitespace between "cols" and "col" nodes.
Possible solution is to skip all whitespace like this
```
while(xr.Read())
{
//skip whitespace
while (xr.NodeType == XmlNodeType.Whitespace) { xr.Read(); }
if (xr.LocalName != "col") break;
```
