View 1 RepliesI 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 has been simplified, "information ..." in the sql insertion command represents 1803 characters.
ExcelObjConn = "Provider=Microsoft.Ace.OLEDB.12.0;" & _
"Data Source=" & fileName & ";Extended Properties=Excel 12.0 XML"
ExcelConnection = New System.Data.OleDb.OleDbConnection(ExcelObjConn)
ExcelConnection.Open()
Try
SqlCommand = "CREATE TABLE ABC ([row1] text, [row2] text, [row3] text, [row4] text)"
ExcelCommand = New OleDb.OleDbCommand(SqlCommand, ExcelConnection)
ExcelCommand.ExecuteNonQuery()
ExcelCommand.Dispose()
For i As Integer = 0 To 1124
SqlCommand = "Insert into ABC ([row1], [row2], [row3], [row4]) Values ('information...', 'information ...', 'information ...', 'information ...')"
ExcelCommand = New OleDb.OleDbCommand(SqlCommand, ExcelConnection)
ExcelCommand.ExecuteNonQuery()
ExcelCommand.Dispose()
Next
Catch ex As Exception
Finally
If ExcelConnection IsNot Nothing Then
ExcelConnection.Close()
ExcelConnection.Dispose()
End If
End Try
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.

View 6 RepliesWhen I click on the export button and get the pop-up where you choose the export format....when I choose the Crystal Reports format and click ok,the contents of that pop-up window is now the same as the page where I clicked the export button along with an 'Access Denied' message above the tool bar.
If I choose any other export format,this does not happen and I get the expected dialog where I can choose to open or save the export file.It seems to be a permissions issue, but I can't figure out what CR is trying access that it doesn't have permissions for.

In C# ASP.net, could someone show me how I can write entries from an Array/List to a CSV file on the server and then open the file? I think the second part would be something like - Response.Redirect("http://myserver.com/file.csv"), however not sure on how to write the file on the server.
Also if this page is accessed by many users, is it better to generate a new CSV file every time or overwrite the same file? Would there be any read/write/lock issues if both users try accessing the same CSV file etc.?
Update:
This is probably a silly question and I have searched on Google but I'm not able to find a definitive answer - how do you write a CSV file to the webserver and export it in C# ASP.net? I know how to generate it but I would like to save it to www.mysite.com/my.csv and then export it.

View 3 RepliesExporting DataTable data to CSV file. It is working fine as expected as long as the export records are less than 65,536. When the records are more than 65,536 , only 65,536 records are shown in CSV file (remaing records are not shown). When the export is done(with more than 65,536 records), opening the file shows below message window. File is not loaded completely. When the Ok button is selected, below text displayed...
This message can appear if: You are trying to open a file that contains more than 65,536 rows or 256 columns. To fix this problem, open the source file in a text editor such as Microsoft Word. Save the source file as several smaller files that conform to this row and column limit, and then open the smaller files in Excel. If the source data cannot be opened in a text editor, try importing the data into Microsoft Access, and then exporting subsets of the data from Access to Excel. You are trying to paste tab-delimited data into an area that is too small. To fix this problem, select an area in the worksheet large enough to accommodate every delimited item.
Notes: You can not configure Excel to exceed the limit of 65,536 rows and 256 columns. By default, Excel places three worksheets in a workbook file. Each worksheet can contain 65,536 rows and 256 columns of data, and workbooks can contain more than three worksheets if your computer has enough memory to support the additional data. Solution:- Seems like here is the suggested solution. But it takes ages to export and show data. An export is done about 15mins ago, still it is doing that. Has anyone managed to find/resolve this issue?
