View 5 Repliesthis is a reference to the thread:he problem I was having while loading data into a datagrid from Excel is solved when I have changed the connection string property IMEX to 1 in:

the logic of this has gotten the best of me. In my scheduling app the user creates schedules for 6 groups(RNAM, RNPM, NTechAm, NTechPM, WCAM, WCPM). The user can then preview each schedule in a DGV on a separate form. After previewing all 6 schedules they then export them one at a time to excel. I want to do after the first schedule is done, is keep the workbook open and add a new worksheet for each remaining group(total of 6 worksheets).
[Code]...
Should I do away with checking if the file exists and just create the workbook and keep it open and then add all 6 worksheets by exporting them 1 at a time.
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.

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.
View 5 RepliesI 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).

I am writing a program that uses several textboxes that a user will fill in and then click the add button to add the data into the datagrid. There is no backend database or anything. Just seeing the data in the program only.
What I want to do is then export this data from the datagrid into a file, preferably excel.
I've done copying textbox data into txt files but I can't find a method to copy datagrid data into a file.
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

View 4 RepliesI have some code that i am using which exports a datagrid view to an excel file. It works, I am trying to either delete or clear a series of unused columns at the ens of the sheet, there are 9 columns. I am using the following loop to rid the columns and i am getting Exception from HRESULT: 0x800A01A8.
I did some research and it seems to do with late binding, code that is giving me the exception follows:
Dim ZZ As String = "J"Dim AJ As Excel.Range = CType(wSheet.Columns("A" & ZZ), Range)
With AJ
For g = 1 To 9
.Select()
.ClearContents()
[Code]...
I read on msdn if AJ in this case starts out as nothing then vb will throw this exception and to use early binding. I cant bind a column if it hasn't been created yet, so i played around with the placement of the declaration of AJ to no avail, what is the right Direction i should take to fix this issue?

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?
