I have to import a tab delimited file into Excel and export it back out to correct a formatting issue caused by FoxPro. I need to pad a column with 10, Zeros and that is good with this here: objxl.columns("B:B").numberformat="0000000000". However I have 2 cells in the sheet, row 1B and 2B that I want to exclude from the number format above. Because it is a date field and it writes to that same column so it pads my date.

My pc is a Vista SP1 + VS2008 I try to import a csv file into an existing access database with the following code but I have the message that the database is only in read access and I can't update it with the csv file.I tested the code on an other pc with XP and VS2005 and it works.
I am looking for some guidance with the most optimal or efficient way to export a dataset to an excel file. I have searched the forums and found a number of methods to do this. However, the code I am currently using is very inefficient as it is itterating through the rows and columns to create the excel file. The app I am working on needs to be able to create 50 or so excel files each with 500+ rows and 40-50 columns. This method seems to inefficient for my use.
I have seen some code out there to use an ODBC call to excel to create the file. I am wondering if someone can verify that this is the most efficient way to meet my goal. It should also be noted that after the export I will want to do some basic formatting of the sheet. Adding bold column headers, autofilters, and autofit all columns.

I am using asp.net oledb to export information to excel file. I encounter problems when the information to export becomes too big, in this case the code I have given below, the excel file generated becomes an empty spreadsheet.If I changed the loop to 1123 for insertion of the rows. The generated excel file is fine, 1125 rows, and 4 columns shown.A test program in windows form is also working fine regardless of how many rows.[code]I couldn't find a solution to my problem as well. What I did eventually was to run the process using another separate windows service. The code works perfectly fine running from a windows form or service program, but not asp.net, not sure why.

Dim conn As New OleDb.OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:PureshowPureshow.mdb;") Dim cmd As New OleDb.OleDbCommand("SELECT PWTC08.Lot AS LotID, PWTC08.Reg AS OfficialID FROM ((PWTC08 INNER JOIN SWTC08 ON cint(LEFT(PWTC08.Lot,

I am almost to the point of just outputting to a CSV and telling the user to import into excel each time. I can export to excel if I put it in a webform, but I cannot figure out how to do using a console app.
