View 1 Repliesi've got some problem reading excel files to store into sqlserver database. currently my code has a fileupload control and a button for me to save the excel file into a folder and read the data inside the excel file and write it into the sql database. The code works only if the excel sheet name is Sheet1.xlsx, however i tried upload a diff file named ImportUserFile.xlsx and it gave me the exception below. 'ImportUserFile$' is not a valid name. Make sure that it does not include invalid characters or punctuation and that it is not too long. i have also tried other file names and it seemed only Sheet1.xlsx works.

I want to upload data from an Excel Sheet into my DB. Now my major requirement is, I do not know the header count in the files to be uploaded and they may vary, for example one file may have 3 headers while some may have 6. and I want data of both these files to go into a single DB. That is, I want to dynamically generate columns in my DB, and store these values. So how do I go about achieving this.

and i found it, here http://forums.asp.net/p/1480079/3451771.aspxi can fairly easily code for a general dbase (name, address, etc..)my question here with this code is...where does my dbase info go?
my dbase info
dbase name = files
tablename = fileTable
column names = fileOne, fileTwo, fileThree
the file upload object is called "fileupload1" and this all goes with a "submit" button
also, that is pretty much for one file, what if the user is uploading more than one file? do i just add more if/then statements, one for each fileupload object?

View 1 RepliesI creating a page where our clients can view advertising images and then able to download the images in different file formats. So I need the images and the different download types all saved into the same row in the database so that when I go to display them on the page when they select a picture the right download links will be there. So here where my problem comes in, I don't know how to code it so that I can insert mulitiple file paths into the database at once. The images are saved in a table called images. The downloads are saved in a table called Image Downloads.
Here is the code for the page I have it coded to submit the images to the database but not sure how to add the rest. I have got three different sql datasources for each table not sure if that's the way to go.

I need to read an Excel work book with 2 sheet which have more than 60,000 records. The application is an ASP.Net application so the performance matters.
Which approach should I take? Sohuld I do it using Microsoft.Office.Interop.Excel or should I do it using OLEDB in ADO.Net?

I have a C#/Asp.net web application which caches SQL DB schema information. Is there a way that I can determine what child relationships a given table has? I have looked into using the DataTable.ChildRelations property, but it is never populated with items unless i manually create a relationship using the .add property. I also have access to DataColumn information for each column in the database.
View 4 RepliesI need to populate a database (SQL Server) with some data from a templated excel document.Here are some approaches:
A) User upload a file.xls or file.csv that the server reads, checks and updates the database (cons:the uploaded file might be too big. file.* needs to be in correct format)
B) User downloads a tool.exe to read and upload file.xls (cons: maintenance of the tool.exe)
C) Use of a web service in excel? (don't know how to do it) but
this article might give you a hint
Which one is the best to use? Are there any others?

View 1 RepliesI'm trying to store multiple selected checkboxes from a single checkboxlist, but i don't know where to start. Imagine i have three tables: tbl_events, tbl_organisors and tbl_settings and i want to store the organisors of an event. Each event can have multiple organisors, so each organisor should be added as a single row into tbl_settings. I know how to bind tbl_organisors to a checkboxlist, but how do i store the results (meaning: add the rows to tbl_settings) ?
tbl_events: Event_ID (PK) and Event_Name
tbl_organisors: User_ID and user_name.
tbl_settings: Settings_ID (PK), Event_ID and User_ID
Checkboxlist:
[Code]....
SQLDatasource:
[Code]....
Initially all checkboxes will be unchecked, but users must be able to select multiple organisors from the checkboxlist and then store them into the DB by submitting a form. So the query will look something like: INSERT INTO tbl_settings (user_id, event_id) VALUES (@user_id, @event_id). And this is where my head cracks
1) How do i loop through all selected checkboxes and store each value (user_id) in a new row in tbl_settings?
2) After saving, the users reloads the page and the organisors he just selected must be selected by default in the checkboxlist. How?
The short story is, I'm developing an SSIS package to select from a remote Oracle database (read: no Windows Authentication) and store into an SQL Server db. I can execute the package just fine in development and after importing, but when I run it as a scheduled job, I get an ora-01017 error (bad un/pw). The details are, I built this package and tested in in BIDS but came across the problem that BIDS really doesn't save the password I'd set for the Oracle connection. After poking around a bit, I found this
[URL] which showed how to create an XML configuration which the package could then read. Fiddled around with that, got it working in BIDS. Connected to Integration Services on the server on which I want to run the package, imported it, right-clicked and did the "Run Package" option as a test, it works great. However, when I connect to the same server's Database Engine to create and schedule a job, I cannot connect to Oracle. For some reason, it seems as if the package is not reading the configuration when run in schedule.
I've tried removing the job and re-working it, thinking maybe it didn't pick up the new version when I re-imported the package. A new job had the same problem. Next, I tried re-naming the .dtsConfig and doing the "Run Package" option as a test. Failed with the same error. A bit surprised, I thought I'd get some kind of file error and we wouldn't get as far as trying to talk to Oracle. Anyway, thinking maybe it's permissions on the configuration, fixed the .dtsConfig name and gave full access to Everyone. That ought to let the Agent see it. Scheduled up the job, still can't talk to Oracle. So it seems as if the scheduled version is ignoring the configuration. Anyone have any idea what I'm missing, that scheduling an SSIS package makes it act differently than running it manually? BTW, the instance under which we're running the package is VS 2005. BIDS 2005 to build the package.
