View 6 RepliesExport DataSet To Existing Excel Worksheet
Nov 4, 2010VB2005. I have several DataSets that I create or grab from an external source. One example is
Dim sql As String = "SELECT TOP 30 * FROM myTable" & vbCrLf & _
"WHERE Area='YY' AND CarNum='734EP' " & _
"ORDER BY ProcDate ASC;"
Dim da As New OleDbDataAdapter(sql, myOLEDBconn)
'create a dataset and fill it with the returned data.
Dim ds As New DataSet
da.Fill(ds, "MyData")
Once I have these DataSets I then have to pump them into a specific worksheet in an existing Excel2007 workbook. The connection and interaction with Excel and the workbook/worksheet is already established and that works. But I am stuck in exporting the DataSets
into the specific worksheet.
Note that I have already scoured the web and MS Community site and all code that I have found so far iterates through each and every row and column of the DataSet and then adds that to the worksheet in a cell by cell manner. This is fine and in testing that works. But there has got to be a better way to do this. For even a moderate sized DataSet the exporting just takes a long time. 25 records with 15 columns takes about 10 to 15 seconds.
I've also been experimenting with some scratch code I found that converts the DataSet to an ADODB Recordset and then uses the xlwksht.Cells.CopyFromRecordset function to export it in one fell swoop. I haven't got this one to work just right but it seems in the end it also does an iteration through each and every record and field to convert to the ADODB recordset.

View 2 RepliesVS 2008 - Most Optimal Or Efficient Way To Export A Dataset To An Excel File
Oct 29, 2011I 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.
VS 02/03 - Using ODBC To Export Tables From A Dataset To Excel File Without Auto-formatting
Jan 22, 2010I'm using ODBC to export tables from a dataset to an Excel file without auto-formatting Excel or even needing to have Excel installed on the users PC. This works great but I just had a request to autosize the columns and make the header line bold. The only way I know of doing this is to fully automate Excel to control the row/column/cell formatting. Does anyone know a way of doing this without auto-formatting Excel?

Zip Code Is Dropping Leading Zero When Displayed On Excel. Export To Excel From XML To XSLT Transform?
Aug 16, 2010I am exporting data from vb.net to excel and it is dropping the leading zero when its displayed on excel. How can I avoid the dropping of leading zero? I read the solution of adding a single quote but it makes my excel sheet column ugly. Also users will complain if they see a single quote on zip code field.vb.net code
Response.AddHeader("content-disposition", attachment)
Response.ContentType = "application/vnd.ms-excel"
Response.Charset = ""
the stored procedure outputs XML and it is transformed by XSLT before it is displayed on EXCEL
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<HTML>
[code]....
adding a single quote or manipulating excel sheet with column formatter (general/numbers ) etc. I don't want user to make any changes on excel to get the display properly when the excel is displayed from web page it should be all set with proper formatting. also we have no control over client excel software?

.net - Exporting To Excel Removes Leading Zeros. Css Styles To The Table Does Not Carry Over To The Excel Export?
Aug 4, 2011I have an asp:table which I want to exported to excel. One of my fields are alpha numeric and when exported to excel the leading 0s are stripped off. After going through this thread: Validation (CSS 2.0): 'mso-number-format' is not a known CSS property name I would like to use the css method "mso-number-format:@;.But the css is not exported to excel. I just tried to test it with simpler css things like bold font etc but its not getting carried over. I can see that if I surround my asp:Label with tags this change gets carried over to the excel but not the css bold . Other solutions in other thread does not work for me as ="00111" shows up as desired in excel but in the web form it shows up as ="00111" which is not what i want.

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.

Excel Export In ASP.NET + .NET Bug?
Mar 20, 2009We use a small bit of excel exporting code in our app code at work to export XML controls from our ASP pages into an excel format using the following code:
Public Shared Sub Export(ByRef xml As Xml, ByVal filename As String)
Dim response As HttpResponse = HttpContext.Current.Response()
response.Clear()
[code]....
This is all fine, except we've encountered a rather frustrating bug. If the XML control has a link in it then the export code is called again. We have a button which will say "Export to Excel" from the .aspx page which simply calls ExcelExport.Export(Xml1, "MyFileName") which is in a LinkButton click event.Here's the order of events based on the form submit (selecting filters)
Enter filters
Submit form
Page_Load occurs
[code]....
So the user submits a form which loads up the XML control in a nice viewable XSLT page. Then they click "export to excel" which will give them the page in excel instead, then they click on the XSLT page, for example a link, but the save dialog for excel comes up again. We've gone through the series of events, and if we do not call the excel exporter it goes through the series of events as normal. If we do call the excel exporter it will go through the page load event and unexpectedly go into the link button click event.
