Thanks

Thanks again.

Thanks all!

I gave Cell A1:C10 with a name ‘Chargeable’ in Sheet1, how can we get the data from it?
I’ve tried using ‘Select * From [Sheet1$Chargeable]‘ but it didn’t work.

string sql = “SELECT * FROM [sheet1$]“;
cmd = new OleDbCommand(sql, connection);
OleDbDataAdapter da = new OleDbDataAdapter(cmd);

DataSet ds = new DataSet();
ds.Tables.Add(”xlsImport”);
DataTable dt = ds.Tables[0];
dt.Columns.Add(”field0″, typeof(string));
dt.Columns.Add(”field1″, typeof(string));
dt.Columns.Add(”field2″, typeof(string));

da.Fill(ds, “xlsImport”);

This was the data formatin the excel file. the actual data was from 4th row. how to read the data from nth row and display in grid

I found a solution for this problem.
Microsoft DAO 3.5 Library is needed

When i try to do a “select * from [CLEAVEDB62305offer_0529163742Ge$10:100]” , it shows me an error message.
Obs.: If I try : “select * from [CLEAVEDB62305offer_0529163742G$10:100]” it works fine
Anyone have any idea to solve it ?

The other option would be to change the “Extended Properties=”"Excel 8.0″”" code in the connection string to an earlier version. I think I’ve seen elsewhere that you’d want to use Excel 5.0 for the older worksheet formats, but I’m not sure; you’d have to test that out.

I got it , I needed to set IMEX=1 ; and now I m getting all values.

But thats very strange that why I was getting the values column X,Y,Z if I add value for for these columns for other rows ?

Any how my problem is solved thanks for help , But I think Jet driver should throw some exception , warning or something to warn user for this kind of situation.

Send us the
connection string used to read the excel worksheet, the data of the X,Y,Z columns and
Registry Setting of
“TypeGuessRows” and “ImportMixedTypes”

First of all Grt article.
Actually I m reading Excel file with columns till ‘CH’ and 15 rows.
My problem is due to some reason its not reading the values of only these 3 columns X,Y and Z.
(Column X,Y,Z have only values for row 12,13)

If I add value for column X on row 5,6 ( or any row ) I strat to get values of whole column and thats true for Column Y,Z.

Now this is very weird , I have check the excel sheet and those columns are no different from other columns in any regard , I have few other columns who have values against 2,3 rows and they all are showing proerly.

Any sugesstions for my problem ?
Thanks,
Maverick

Excel File column contains: 18520022
This will be retrived as: 18520000

If we use in the select query from excel like
“select Format([ColName], ‘0′) from [SheetName]“, the same issue exists.

If we put ‘ at the beginning of cell then the it is readed the original data. But this is not efficient way of solving the issue.

Have tried a lot on this issue this is the only way to get rid of the problem.

Hoping anybody can help me solving the issue.

One small addition. While reading the sheet names, in case there is . in the sheet name for example .net data, it will replace the . with #, meaning in above example it’ll return #net data rather than .net data. While coding make sure to handel this exception.

same problem for me
long integer is reading like this
4.08217e+009
4.08217e+009
please help

string.Format(”{0}”,item[i])

Thank you Pronojit for this tip.

I was wondering, is there anyway I could change a worksheet setting via this? I would like to use the above to turn on/off gridlines for a given worksheet. Do you think that is possible? Thanks

This, for instance does *not* work. Looking for an alternative:

SELECT *, CAST([col name] AS DATE) FROM [table name]

This is truly awful ADO implementation…

I am wondering what will happen when the worksheet has (say) 80 rows and the TypeGuessRows is set to 0.

Will the JET engine scan all the rows upto 16384 or just upto the last (ie 80th) row of the worksheet.
