Databases :: Reading Text File Into DataReader?

Jul 8, 2010

I'm trying to read data from a text file into a DataReader object using the following code but I get an exception:

OleDBException was unhandled.

Cannot update. Database or object is read-only.

Also, I would like to know if it is efficient to read data of a text file into a datatable instead of using StreamReader object and traversing through the recordset.

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.

Databases :: Reading CSV File From The Fileupload And Then Retrieve The Data?

Mar 4, 2010

1) I need to make reading CSV file from the fileupload and then retrieve the data.

2) I need to load CSV and the 3 columns rise two functions.

Load CSV data and then stored in a database, but I need to save storage space vary according to 3 column.

CSV Example:
1 column - Cat, 2 column - Black, 3 column - 1
1 column - Dog, 2 column - Brown, 3 column - 2
1 column - Cat, 2 column - Black, 3 column - 1
1 column - Dog, 2 column - Brown, 3 column - 2

Now I need to load the CSV in C # and column 3 to distinguish what the operation is carried out.When the load line in column 3 contain the value 1, so will save the table 'Cats' when the value 2 and is saved in the table "Dogs".(Note: Data are separated ";")

C# - How To Cause A Browser To Open A Tab Delimited Txt File In Excel

Mar 18, 2011

We have a tab delimited file that we are making available for download. The file extension is txt, but the users want it to open automatically in Excel. The previous developer had used the following code:


The ContentType is being set to Excel, but that doesn't seem to have any effect. I am guessing the txt file extension is causing it to be picked up by notepad or the like instead. I have tried just renaming it to a xls extension, which works but Excel complains that I am trying to trick it or it might be a corrupted file.

Best Method To Attach Or Import Data From A Comma Delimited File To Access?

Nov 15, 2010

I have a project I am working that requires me to go to an FTP port and copy a file to the local machine... so far so good... the next step is to take the comma delimited file and import the records (rows) into a local Access database...

Should I be looking the Attach method in Access? To attach and dump all the data in one shot?

OR To open the file with StremRead and process each row one at a time?

I am using VS2008, C#, .NET 3.5, Access 2007... once in production there could 20 - 30 thousand records to be appended to the DB then normalised.

WCF / ASMX :: Add Service Reference Reading Svc File But Not Reading Service?

Mar 10, 2011

I was trying to go through this tutorial:


but when I tried to add the service reference to the silverlight app, the Add Service Reference window would show me that there was a service file, but the node wouldn't expand to show the rest of the files that contain the services and what not. I got this error instead:

"An error occurred during the processing of a configuration file required to service this request. review the specific error details below and modify your configuration file appropriately."

"Parser Error Message:There is no service behavior named 'AdventureWorks_WebServer.Service1Behavior'."

"Metadata contains a reference that cannot be resolved: 'http://localhost:55579/Service1.svc'.

The server did not provide a meaningful reply; this might be caused by a contract mismatch, a premature session shutdown or an internal server error.

If the service is defined in the current solution, try building the solution and adding the service reference again."

Reading Txt File And Modify Content To A Output File?

Jan 5, 2011

I would like to find a way to read a txt file (in my case delimited by €). I need to change the order of the columns and also add and remove some columns. My output file should be a txt file delmited by ;.

I tried Jet.OLEDB to read the file and put it into a datatable and then used a stringBuilder and streamwriter to get an output file in .txt format. However. This does not me since IŽ, reading the txt file from start to end and my output will be the same. It does not seem like I can have a custom sql statement when reading the file. The only query that works is

Dim da As New System.Data.OleDb.OleDbDataAdapter("Select * from 1.txt", TextConn)

How can I possible modify a txt file?

This is my code for now:
