We should analyse the second row to find the correct type and use that type 
for the DataColumn.. Currently i only changed to add the DateTimeValue 
instead of the Value.

for (int currentRowIndex = 1; currentRowIndex <= Cells.LastRowIndex; 
currentRowIndex++)
            {
                DataRow dr = dt.NewRow();
                object value = null;
                for (int currentColumnIndex = 0; currentColumnIndex <= 
Cells.LastColIndex; currentColumnIndex++) {
                  if (Cells[currentRowIndex, currentColumnIndex].IsEmpty)
                    dr[currentColumnIndex] = Cells[currentRowIndex, 
currentColumnIndex];
                  else {
                    switch (Cells[currentRowIndex, 
currentColumnIndex].Format.FormatType)
                    {
                      case CellFormatType.Date:
                      case CellFormatType.Time:
                      case CellFormatType.DateTime:
                        value = Cells[currentRowIndex, 
currentColumnIndex].DateTimeValue;
                          break;
                      default:
                        value = Cells[currentRowIndex, 
currentColumnIndex].Value;
                        break;
                    }
                    dr[currentColumnIndex] = value;
                  }
                }
                dt.Rows.Add(dr);
            }

Hi Guys,

 That last correction I had suggest don't quite work for me, so I Resolve
to Add just 2 new Types on cell Format to make it easy... 

 If you want to you it, fill free to do so: 

After yours "public static readonly CellFormat Date = new
CellFormat(CellFormatType.Date, @"YYYY\-MM\-DD");"

I write: 

        /// <summary>
        /// Format the DateTime with: "HH:mm:ss" e.g: 14:45:00
        /// </summary>
        /// <example>Format the DateTime with: "HH:mm:ss" e.g:
14:45:00</example>
        public static readonly CellFormat Time = new
CellFormat(CellFormatType.Time, "HH:mm:ss");
        /// <summary>
        /// Format the number with: "#,###.00000" e.g: 100.12345
        /// </summary>
        /// <example>Format the number with: "#,###.00000" e.g:
100.12345</example>
        public static readonly CellFormat Engineer = new
CellFormat(CellFormatType.Scientific, "#,###.00000");

This problem has already been mentioned, but here is some more detail.


What steps will reproduce the problem?
1. Reading a large file. (For me large is from around 10mb)
2.
3.

What is the expected output? What do you see instead?
I have encountered this problem at two different stages (not sure what it 
depends on, possibly:

1.
internal static Int32[] ReadArrayOfInt32(BinaryReader reader, int count)
        {
            Int32[] data = new Int32[count];
            for (int i = 0; i < data.Length; i++)
            {
                data[i] = reader.ReadInt32(); //throws EndOfStreamException
                //reader Length is   23164416
                //reader Position is 2106864640 (I suppose Length is 
supposed to be greater than Position?)
            }
            return data;
        }


2.
        internal int[] ReadSectorDataAsIntegers(int SID)
        {
            int offset = GetSectorOffset(SID);
            Reader.BaseStream.Position = offset; //throws 
ArgumentOutOfRangeException (GetSectorOffest returns large negative int)
            return ReadArrayOfInt32(Reader, SectorSize / 4);
        }

                dt.Columns.Add(Cells[0, i].StringValue, typeof(String));

            // Extract data
            for (int currentRowIndex = 1; currentRowIndex <= 
Cells.LastRowIndex; currentRowIndex++)
            {
..

1. Try to open big Excel file (about 300 Mb)


It seems problem is in "int" type insted of "uint" in position and

Hi all,
first of all thank you for your good library, I've been using for only a 
few days the dll compiled on 2009-02-12 in a VB.net project running on 
winXP. I'm not a good programmer so maybe it's my fault and I'm missing 
some steps, but I experience a problem with date. My code get a date value 
from a DataView and put it in a cell, but when I open the xls file I find 
1 day added, i.e. february 25 instead of february 24, note that if I stop 
the code during debugging and read the cell value it is the right one.
No problems with other cells containing decimal or string values.
This is an extract of the code:
........
Dim MyDataView As DataView = New DataView MyDataset.Tables(MyTable))
dim MyWorksheet As Worksheet
....the dataview is rowfiltered.........
Dim MyDate As Date = MyDataView.Item(0).Item("date")
MyWorksheet.Cells(Riga, 0) = New Cell(MyDate, "DD\-MM\-YY")
...........

Another question: is it possible to change font color, backcolor, border 
or alignement in a cell?

Many thanks.

     Stefano

hi,

i would suggest adding the following to the Cell.cs:

public override string ToString()
{
  return StringValue;
}

because i think it would be more usefull than default ToString which 
returns ExcelLibrary.SpreadSheet.Cell

Classes in SpreadSheet logical layer should not reference classes in 
storage layer.

What steps will reproduce the problem?
1. Add a number with more than 1 decimal place (using code: .Cells(0, 0) = 
New ExcelLibrary.SpreadSheet.Cell(1.2345)
2. Save spreadsheet 
3. Number shows as 1.23 (rounds up or down)

What is the expected output? What do you see instead?
1.2345

What version of the product are you using? On what operating system?
Latest dll, VB2005, XP

Please provide any additional information below.

it fails when I create two worksheets and save (workbook.save)
it's no error when add multiple sheets into workbook but failed when save.

is it possible to save an excel more than a sheet? thanks

Is it possible to implement such thing?

example:
input: two merged cells
------------------
     CellData     |
------------------

output
--------------------
CellData | CellData |
--------------------

Hi!

 I'm thinking in use your excellibrary into my program, but for this I will
have to made a little modifications, to transform this great development
into a dll version...

 I can do it, for you, your do you prefer I just do for my propose only?


Thanks for written this very nice work.

What steps will reproduce the problem?
1. create a new file or open one
2. make changes
3. hit the save button
4. the changes aren't saved

What is the expected output? What do you see instead?
i wish the data was saved, the data isn't saved

[deleted issue]

What steps will reproduce the problem?
1. Opening the attached file using workbook.open().
2.
3.

What is the expected output? What do you see instead?

The code throws an exception in the Record.ReadString() method.  So there 
is no output.

What version of the product are you using? On what operating system?

I don't know what version of the product I'm using.  I downloaded my 
current version on 2-13-2009 from 
http://www.codeproject.com/KB/office/ExcelReader.aspx.  

The attached files were created using Excel 2003 on a Win XP system.

Please provide any additional information below.

While attempting to open a file using your product, I sometimes get an 
error.  The error occurs in the Record.cs file, in the ReadString() 
method. Specifically, the error occurs when the code then reads an 
incorrectly large value for the variable "stringlength" (representing the 
length of the string to read), or the variable "size," (representing the 
length of the Asian phonetic settings). This large value is typically 
greater than 10,000 or even 100,000, and creates an exception because that 
many bytes cannot be read into an array.

Through testing, I've found that the error seems to occur when your code 
switches to a continued record using SwitchToContinuedRecord() because the 
end of the current stream has been reached.  The switch to a continued 
record I'm referring to occurs on line 3 of the ReadString() method. I've 
been unable to determine the cause of the error. Maybe its just because 
the file is from Excel 2003. Or maybe its because about 30-35 records end 
up in the "default" case in the Record.Read() method.

Steps to reproduce the problem:

1. create a XLS 
2. Open it with M$ 2003 SP3

The "index to active (displayed) worksheet" WINDOW1 Offset 10 Size 2
doesn't work for Office 2003 SP3

(for example: window.ActiveWorksheet = 0;) I can see the first worksheet
(of 2 for example) but the name of the worksheet isn't bold, the worksheet
isn't activated. You can try to print the sheet, then it will tell you that
there aint any data to print at the active sheet.

I think its a M$ Office BIFF8 problem, because its shows ok with OpenOffice
3.x. The right worksheet is active and the worksheet name is bold, i can
print it. 

Can you help? What can I do, to fix it?

System: Windows XP 64bit latest updates, english
Office: M$ Office 2003 (SP3) Professional, german

and your latest great library!

I feel that ExcelLibrary.Office.Excel is also not a good name.
My propose is:
Use the following namespace for logical layer:
 ExcelLibrary.SpreadSheet
Use the following namespaces for storage layer:
 ExcelLibrary.BinaryFileFormat
 ExcelLibrary.BinaryDrawingFormat
 ExcelLibrary.CompoundDocumentFormat
And change the project directory structure correspondingly.

While I was writing test case for DataSetHelper, I noticed that
Workbook.Save() may create malformed Excel workbook under some special
circumstances. 

Workbook.Save() wrote to file without any warning. However, when open the
same file using Workbook.Open(), I get System.IO.EndOfStreamException. If I
try to open the file using Excel, I also get "Unable to read file." error.

I have created a test case to demo the issue, SimpleTest.WriteCellTest1(),
please have a look.

Please provide any additional information below.

The current version of the library does not seem to store Font records.  
Am I mistaken?  

It does not seem difficult to store font records and make them accessible 
through the workbook.  I have modified the files below in the following 
ways to account for font records:

1. SharedResource - added Fonts() list
2. WorkbookDecoder.decodeRecords - adds FONT records to the Fonts() list 
in SharedResource
3. Added RichTextFormat class to SubRecords folder.
4. SST (extended version) - added variable to hold all "RichTextFormat" 
data for all strings in SST
5. SST (extended version) - modified decode() to call readStringRTF() read 
the RichText info into a separate variable
6. Record - added ReadStringRTF(), which reads and stores the "rich text 
format" data associated with a string
7. Record - added decodeRichTextFormatting()

I've also attached my revised Worksheet file.  I am interested in 
retrieving the font record for a given character in a cell.  I implemented 
a binary search through the rich-text formatting runs (stored as in the 
attached files), although I did this using an old version of your project, 
so it does not compile properly now.  

Anyway, I hope you implement the font records in a forthcoming update.  It 
would be really helpful.

What steps will reproduce the problem?

Workbook workbook = new Workbook();
Worksheet worksheet = new Worksheet("Test");

worksheet.Cells[0, 0] = new Cell(101u);
workbook.Worksheets.Add(worksheet);
workbook.Save(tempFile);

What is the expected output? What do you see instead?
System.Exception: Invalid cell value.


Please provide any additional information below.
Patch included 

What steps will reproduce the problem?
1. Make a xls file read only
2. Call Load on file


What is the expected output? What do you see instead?
Allow reads from xls file. Exception was thrown, access denied to file

What version of the product are you using? On what operating system?
Latest. XP

Please provide any additional information below.

May need to add a calculation engine

What steps will reproduce the problem?
1. Open an excel file that has formatted text using CompoundDocument.Open
2. Save it with a different name. All the format was lost

I expected that the format were kept.

The same happened when I set a bold font programmatically and then saved 
the file. Format is not taken into account

The version of the product is of 03/31/2009

What steps will reproduce the problem?
1. Create a new cell or access a cell that already exists
2. Try to set the background color of the "Cell" object

What is the expected output? What do you see instead?

We should be able to write:
myCell.BackColor = System.Drawing.Color.Yellow;

Instead, the property is read-only.

What version of the product are you using? On what operating system?

In GetSATSectorID should be checking for SATSectorIndex == NumberofSEcIDs -
 1

In AllocateSATSector it appears to be confusing sectors and sectorID's 
i.e. for each new sector "SecIDCapacity" new sectorIS's should be 
available (not one more as would be the increment for number of new 
sectors).

Hi,
when I try to print the .xls file created got an error from excel (2002 
and 2007 running on winXP); it's in italian, a rough tanslation could 
be "I can't find any information to print". The problem disappear if I 
enter any value in a free cell.
With OpenOffice the error doesn't appear and the printing is normal.
Thank you.

I am using the ExcelLibrary Dll into my class library to read excel 
documents. One of the methods that I call and which in turn has calls to 
the dll's methods and objects, fails on the step of creation of Worksheet 
object.

When I comment the Worksheet declaration statement the code works fine.

What steps will reproduce the problem?
1. Create a spreadsheet using excellibrary
2. Open the spreadsheet in Excel
3. Try to print the spreadsheet

What is the expected output? What do you see instead?
Should print, instead get message 'Excel could not find anything to print'
If you copy the data to a new spreadsheet then it prints fine.

  Hi!

 In my code i used: 
  planilha.Cells[i + 4, 0] = new Cell(intervalos[i].dtTime);
  planilha.Cells[i + 4, 0].DateTimeValue = intervalos[i].dtTime;
  planilha.Cells[i + 4, 0].FormatString = "h:mm:ss";

I expected to set a DateTime to the property DateTimeValue, to in next line
format to a time. 


Error: SharedResource was NULL !

                this._value = days;
            }

Since we move all existing code into this new project, we should consider
to change existing namespace - QiHe into ExcelLibrary. This is more
consistent and also less confusing for the users of this library.

Cannot open one xls file in OfficeDoc. Exception in this source code of

            BinaryReader reader = new BinaryReader(stream);
            MaxShapeID = reader.ReadInt32();
            NumIDClusters = reader.ReadInt32();
            NumSavedShapes = reader.ReadInt32();
            NumSavedDrawings = reader.ReadInt32();
            IDClusters = new List<long>();
            while (stream.Position < stream.Length)
            {
                //IDClusters.Add(reader.ReadInt64());
                int drawingGroupId = reader.ReadInt32();
                int numShapeIdsUsed = reader.ReadInt32();
// In this line i has a Exception (Double keys)
                GroupIdClusters.Add(drawingGroupId, numShapeIdsUsed);
            }
        }

    }
}

I remove line GroupIdClusters.Add(drawingGroupId, numShapeIdsUsed); and all
be fine. 

What steps will reproduce the problem?
1. var book = Workbook.Load(filename)
2.
3.

What is the expected output? What do you see instead?
Throws an ArgumentException "Stream was not writable" at:

        {
           ...
            this.Writer = new BinaryWriter(this.FileStorage, 
Encoding.Unicode);
           ...
        }
