What do I need do after this to export my data to excel?
i need to export a query result to excel. I did it using a few methods but it seems that it is taking to long if loading large amount of data like 1000 rows. I did looping a datatable and write the values to excel via excel object 11.0. - 20 secs for 1000 rows exporting the data to CVS but i will have problems formatting the data. using copyfromrecordset using adodb. But they want it to be done in .net Are there any better and faster ways? Must be done programmatically using vb.net.

When this runs, I get an error message that says: System.Data.OleDb.OleDbException: The Microsoft Jet database engine could not find the object 'Sheet'. Make sure the object exists and that you spell its name and the path name correctly. The excel file has only one sheet that is named "Sheet", and the location specified in the connection line is correct. Any ideas on why this may be happening?
I am using Visual Studio 2008 and looking for an efficient and hopefully straightforward approach for exporting data from a DataGridView to Excel. If doable, my preference would be to export the data to Excel without instantiating an Excel application. I found some code on the Microsoft support site that is fairly accessible but the example shows how to export just a few pieces of data. Would someone be able to demonstrate how to modify this code to so that it could be used for large amounts of data (for example, data from a DataGridView).

The CLR has been unable to transition from COM context 0x1b3008 to COM context 0x1b3178 for 60 seconds. The thread that owns the destination context/apartment is most likely either doing a non pumping wait or processing a very long running operation without pumping Windows messages. This situation generally has a negative performance impact and may even lead to the application becoming non responsive or memory usage accumulating continually over time.To avoid this problem, all single threaded apartment (STA) threads should use pumping wait primitives (such as CoWaitForMultipleHandles) and routinely pump messages during lonunning operations.

I'm trying to export the content of a data grid to an Excel file. But here is my problem:
1. If I use a Data Grid which was set to allow Adding and Editing of columns ( this appeared the first time I add the control to the form) , the resulting excel file will show all the content of the data grid, except for the Headers ( Column names) .
2. If I use a Data grid which was set to disabled adding and editing of columns, the resulting excel file is lacking the bottom-most row of the data grid content. The Headers are also not included.
I cannot choose Option 1, since the data grid must not be editable by the user. I cannot choose option 2 since the last row is being omitted. Another thing is that the Column Names ( the data are coming from a MS Access File) are not added into the Excel File for both Option 1 and 2.
Here is the code I'm using. I found it from the net and tried changing the values of i and j but still I can't get the result I wanted.
For i = 0 To dgreport3.RowCount - 2
For j = 0 To dgreport3.ColumnCount - 1
xlWorkSheet.Cells(i + 1, j + 1) = _
dgreport3(j, i).Value.ToString()
Next

I am trying to export an excel file directory into an Oracle table as opposed to looping through the range and executing a lot of insert statements. I would think that there are better ways to accomplish this in .NET but I can't seem to find any other answer besides convert excel to csv & load it using Sql Loader or External Table. Does anyone know a cleaner & more efficient way that looping through the ranges creating & executing insert statements?

I 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.
View 2 RepliesI am building an ordering system for my job. The idea is that the customer will put in a stage name for an item. That stage name is then interpreted by the program.The product id and the amount the customer wants to order is placed in a list box on the form. There are a couple of buttons, ADD, REMOVE, CLEAR, and EXPORT. The user input is handled by input boxes. When the user pushes the EXPORT button, excel should open and list out the interpreted product codes with the corresponding amount to order. I can get excel to open, but I can not get excel to display more than one line. It will display the first product, but then it comes up with an unhandled exception.I can not figure out how to get excel to return down a row and display the next product within the list box.
View 6 RepliesI've written a very simple program that writes a tiny "config.cfg" (text) file to the computer (using StreamWriter), and a second program that is supposed to read that data back.
Unfortunately, it appears you can't save to the same folder as your program under Win7 ("Program Files (x86)" is a restricted folder.) So instead, VB automatically saves my data to the "C:Users(myname)AppDataRoaming..." folder. This is annoying, but tolerable.
PROBLEM IS: How does my second app then FIND my data file (without doing a time-wasting drive search every time the program is run?)
My code:
' Program #1:
Private Sub cmdSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdSave.Click

View 1 RepliesA year ago I saw a beautiful simple code that gets a data table and saves it in an excel file. The trick was to use the web library (something with http) and I'm almost sure it was a stream. I find a lot of code with response but I can't make it work in a win-form environment. There is also a cell by cell code - not interested -too slow. I want to paste it as a range or something close.
View 5 RepliesI can launch Excel with the document I want using VB.Net 2010:
Dim p As New System.Diagnostics.Process
p.StartInfo.FileName = "c: empmyfile.xlsx"
p.Start()
Excel starts OK with the file opened. I edit the file, but when I close it down, Excel doesn't ask if I want to save changes. So it closes and loses my edits.
If I do the same with a text file:
Dim p As New System.Diagnostics.Process
p.StartInfo.FileName = "c: empmyfile.txt"
p.Start()
It opens (in Notepad++), I edit it and close it, and Notepad++ asks if I want to save changes.
I've now tried similar code with a Word document - and that's OK. Also with an OpenOffice Sheet document and that works as well.
This behaviour is happening in Windows 7 with Excel 2010. It works as expected in Windows XP with Excel 2007.
What am I doing wrong with Excel? Is it me?
