Hi,
the same happened to me. I don't think we did something wrong, the files cannot be found in source browser either.

Created Unassigned: First row always skipped (CreateBinaryReader, AsDataSet) [12647]

January 8, 2014, 2:19 pm
$

when reading a .xls (binary) file, the first row is missing in the returned datatables, even if IsFirstRowAsColumnNames=false

__reason__ :
in method 'readWholeWorkSheetNoIndex', line : justAddedColumns = true; is not at the right place

__Patch__ :
```
if (triggerCreateColumns)
{
if (_isFirstRowAsColumnNames || (_isFirstRowAsColumnNames && m_maxRow == 1))
{
for () {...}
justAddedColumns = true; // added by jerome.raffalli
}
else {...}
triggerCreateColumns = false;
// justAddedColumns = true; // removed by jerome.raffalli
table.BeginLoadData();
}

```

Created Unassigned: Missing cell values after empty lines in a binary sheet [12648]

first cell after an empty row in binary .xls file is not detected.

__Reason :__
Too many calls to m_stream.Read();

__Patch :__

```
private bool moveToNextRecordNoIndex()
{
//seek from current row record to start of cell data where that cell relates to the next row record
...
m_currentRowRecord = rowRecord;
//m_depth = m_currentRowRecord.RowIndex;

int Memo_Read_Position = m_stream.Position; // Store current read position [jerome.raffalli]
//we have now found the row record for the new row, the we need to seek forward to the first cell record
XlsBiffBlankCell cell = null;
do
{...} while (cell == null);

// if searched row is < found row, remember to cancel previous reads [jerome.raffalli]
bool Cancel_Read = (m_depth < cell.RowIndex);

m_cellOffset = cell.Offset;
m_canRead = readWorkSheetRow();

// restore read position [jerome.raffalli]
if (Cancel_Read) m_stream.Seek(Memo_Read_Position, SeekOrigin.Begin);

//read last row

New Post: Remove formatting from file

I'm using the AsDataSet() method to import large Excel files into DataSets. It performs extremely well until I hit a file that has a lot of formatting. With formatting, I cancelled after ~ 30 minutes. I then opened the Excel file, removed all formatting, and it worked almost instantly.

I'm using .xls files, not .xlsx.

I might have the option of removing the formatting when they are generated, but it would be a lot easier for me if I could somehow make then work, whether it's by telling ExcelDataReader to ignore the formatting or by somehow removing it before processing.

Any ideas?

New Post: Fork to remove SharpZipLib?

I've grabbed the source of this project and modified it to remove the functionality related to SharpZipLib (SharpZipLib has a GPL license that is a legal problem for my product).

Is there any way to create a fork of this project to track my version? All I saw was a place to upload a patch. I'm removing functionality, so I'm assuming that my "patch" would not be welcome.

Added additional random component to zip temp name as it was only using date, which was quite likely to clash in multithreads

This is the problem with codeplex. No way of forking I know of for this repository. I'd much rather have the whole thing on github. Maybe I should just move it there as I seem to be the only active developer anyway.

Commented Unassigned: Date incorrectly read as Double [11860]

Hi

when trying to read attached file, the reader is incorrectly reading the first column's values (from row 4 down) as double. Instead it should be either string or datetime.

Any fix/workaround for this? We really like this tool but can't use without fixing this.

Thanks,
Stevo

I get the same error but I am NOT able to do a workaround with my Excel flies.
I am using version 2.1 and only get the date as string and it is ALWAYS 1899-12-31.
Extremely confusing.
I try to format column in Excel but the result is the same.

Please come with a solution!!!
This component works perfect for my usage except for this bug.
With a failure on all dates the component is not really a valid option.

New Post: Moving to github?

Hi everyone,

I would really like to move this project to github. There are a few reasons for this:
  1. It's quicker
  2. The UI is much better
  3. People can fork the project and contribute that way. It makes it easier for people to contribute, and that is a good thing.
  4. I'm pretty much the only active developer on this project at the moment and I really prefer git.
  5. I don't know who is actually the admin of the project any more.
So, I'd thought I'd put this up for discussion to see if anyone cared either way, or had a strong opinion about it.

Cheers
Ian
