We have a VB 2005 program that reads data from a database and builds an Excel output file to be emailed. This works fine from my computer but when we put it on the server it fails on the Excel functionality.
The error is: Unhandled Exception: System.Runtim.InteropServices.COMException
Although Excel is not installed on the server we did also build a Setup program to install our program. It copies the Microsoft.Office.Interop.Excell.dll to the server folder with the exe.I thought the setup program should register the Excel DLL and the program should work even if the server does not have Office or Excel installed.
I'm writing an application that imports and tidy up address data into a cleaned, deduped excel workbook ordered in rows with each column as an address field. One of the issues I've ran into is that we sometimes get a workbook where the multiple address fields are held in a single cell with line breaks. I've written code to extract all of this data out of the excel sheet in to a dataset with each sheet as a table and the address fields contained within. I now want to create a new Excel workbook from this data with the address fields in Row and columns the problem I have is I can Open/create the Workbook but when I try to insert a new Sheet (Table) I get an error saying the Workbook is read only....

I have data that I'm taking from an Excel sheet with the ultimate goal of displaying in a DataGridView.
Currently I am just going over the UsedRange of excel data and plugging it into a datagridview. This works fine, but can get bogged down when there 100+ rows of data.
I have also toyed with going from excel into a dataset (using the same wasteful method), and as expected it takes about the same time to load the data. Maybe use the XML from the Excel file?
EDIT:
Some Additional Information:
This is a WinForms application and the user will be picking and loading the excel file at run-time.
EDIT
The Return of Some Additional Information:
The Excel file is located on the user's pc. The general assumption is that they will be loading different files each time they use the application. [not sure if this helps, but might be good to know :)]

I am required to make a program for a small company that reads data from an Excel 2010 file. I have no issues reading this data into my DataGridView control and displaying it for the user.
However, one particular column header is titled "Complete", to which the entire column will either have a "Y" or "N" value. What I want to do is to fill the entire data set from the Excel file (I have done this already), but I need to only display those rows that have the "N" marked under the "Complete" row.
I imagine this would require a For...Next loop based off the DataGridView1.RowCount, but I cannot figure out how I would add just one particular row at a time after checking for a "Y" value in that column. I am only familiar with filling the entire DataGridView.
I included a picture of a sample of what this program would look like (this is how the customer wants it), in case my explanation was not enough.
I found this Code Snippet GridView Export to Excel, that works but does not export the last column and is a little slow.

So I'm working on this project. I got around 60 images or so which I need to OCR, then I'll be inputting that data into my program which formats it and inputs it within this DataGridView. Now, I need the same data to be exported into an excel file. I saw several tutorials online but none of them are current (for VB 2008 or 2010). Either that, or they're not for VB.NET Windows Form Application. [I'm using VS 2010]
I'm fairly new to Datagridview as well. Just learnt how to add data to datagridview using this tutorial:

I have a datagridview(DGV) which contains data based on a user selections from a pre-defined dataset
In point form:
User starts program
program builds datatable
user opens file and program read all data from file into the dataset.datatable
user defines the data they want to see
program displays datagrid based on dataset.datatable and user choices. (basically it displays the whole dataset and removes unwanted columns
ecords)
I want to be able to export the datagrid to excel (not sure which method yet). I have tried the excelexporter component i found somewhere on the msdn forums (it exports the data to look exactly like the datagridview) but its painfully slow. It exports something in the region of 100 records per minute. Most of the time, the datagridview can contain anywhere from 3000-32,000 records. As such, at 100 records per minute, the excel generation can take updwards of 50minutes. Unacceptably slow for the purposes of the program.
What do people recommend as the best method to quickly dump the contents of a datagrid into excel. By quickly, im talking at the speed of about 10,000 records per minute. In all honesty, anything over 5000 records per minute will be fast enough, but the quicker the better!
Is there a way of creating a new dataset.datatable that is built of the contents of the datagridview and then building an excel sheet by connecting to the new dataset?
I would like to be able to export to Excel 2000-2003 at a minimum, but if i can do excel 97 as well it won't hurt.

View 5 RepliesI am filling a datagridview with very lengthy results. Roughly 60k rows on average. I am filling them via an oracle database using a table adapter. The records then have a filter placed on them in the datagridview so the results displayed are a bit different.
My problem: I built an export to excel function which populated a dataset and then red through it and wrote to excel. Bad idea with the amount of records I am using. I tried just writing the records straight to a csv file using streamwriter but I don't very much like this way.
My proposal: I would like to fill an array from the datagridview and then be able to dump the array into excel. However I am having some trouble finding examples on creating an array from a datagridview.
i have a datagridview in vb.net that is filled up from the database. I've researched and i found out that there is no built in support to print directly from datagridview. I don't want to use crystal report co'z im not familiar with it.

I have been trying to make a problem, that allows me to open a excel worksheet into the datagridview, and then print the datagridview out. However, the code that I'm using now to import the excel worksheet into the datagridview, doesn't import the images from the excel worksheet.[code]Is it possible to get the correct posttion of each table, and the images, so if i print the datagridview out, it look just like the excel worksheet, but was just edited before printing.
View 4 RepliesI have done a google and see that many people have asked the question on how to export a Datagridview to a Excel (.xls) file. For some reason I cannot seem to get it to work (i have gotton the program to open an Excel and save it, all hidden in the background). I use a bit of the coding from this source code [URL] but modified it and incorporated it into my program. It connects an OLE Database connection with the excel sheet... but what i want to do is beable to alter the sheet in the datagridview and export it back to an excel sheet. I am not trying to sound pushy when i say this but... if you download the source file i am using you will get a really good idea of my situation..
