Databases :: Read Excel Files Using Oledbreader Row By Row?

Aug 5, 2010

i'm trying to read an excel file and get data on a row by row basis. Since after converting the pdf file into an excel file, the formatting went a bit haywire but if read row by row, i'm still able to retrieve the original data.

As I am unable to generate the excel file using a single worksheet, i have multiple sheets in the excel file. I also need help on reading multiple sheets.

Currently i am onli able to get data via columns but due to the formatting going haywire, i gave up on it.

Databases :: Creating, Opening, Writing To Excel Files?

Aug 5, 2010

I am creating an site where a user uploads an excel file to check if any of the records exist in a database. Then they are returned an excel file with only the records that are NOT in the database.
I was thinking I should do it this way1. User uploads their excel file. The app opens excel file and loads records into a dataset (so far this is working with the code below)2. Using datarow and another function to check if each excel record exists in the database3 If the record does NOT exist, and it is the first record tested, create an excel file called records.xlsx and write the record into the file

4. Check the next record and if it does NOT exist in the database, then check if records.xlsx already exists then open it and write it into it.


Hopefully its clear, sorry if its not, I'm a bit of a novice at this. Is this a good way to do it? Does anyone know of any tutorials that might outline how to open an existing file and write to it?

Exporting Multiple Tables In A DataSet To An Excel File With Multiple Sheets?

Jul 8, 2010

I was in need of exporting multiple tables in a DataSet to an Excel file with multiple sheets. I found a very good article in [URL].[URL] was able to successfully export each of my datatables in the dataset to excel worksheets. This solution worked for small number of rows. But when the data got larger I am consistently getting the system.outofmemoryexception. THis is because the code is using up the memory when creating excel.

Does anyone have another option to do the above?

Databases :: Page Times Out Reading Excel File?

Mar 31, 2010

I have some code that reads records from an excel file and then imports that data into an sql database. The issue only happens when the excel file has more then 350 rows in it. In the middle of the import it just stops executing and I get directed to the 'Internet Explorer cannot display the webpage' page or just a blank page when using firefox.

I dont get any time out errors or any error at all but still I tried messing around with the script timeout settings but still does the same thing at about the 2 min 30 sec mark.

Databases :: Reading Excel File Without Saving To Disk First?

Aug 31, 2010

I need to be able to read an excel file from a file upload control but I can not save the file to disk first, it must be done in memory.


Above is my code for reading the data file if it IS saved to disk, but again, I have to be able to do this without saving the file to disk, it must be done in memory. I have not been able to find any sample code anywhere on how to do this from memory, everything seems to force the file be uploaded, saved to disk, and then read in the connection string, which again I can not do.

Databases :: Reading Hyperlinked Page In Excel File Using C#?

Nov 19, 2010

I understand how to use a connection string object to read excel sheets. What I don't know is how to follow a hyperlink inside excel, grab matching data from the linked page and return it to my database. Essentially, the spreadsheet has two columns:

Title | Class#

Class# has the hyperlink which links to an internal web site. The connected page has a course description and any pre-required classes that must be taken before you can take this class. This is where I'm rather stumped as I've not had to do this type of thing before.
