Web Forms :: Reading And Posting A .csv File Into A SQL Database
Jul 13, 2010
I have the following data that basically I only need a few bits of information from: The only things I need from this are:
Patients Name
Drs Name
Patients Phone Number
Appt Time
Appt Date
and the rest of the information I can discard. A customer uploads this as a .csv file (even though it really isn't as you can see) and I'd like to parse the needed information and post that to my SQL database and discard the rest. I think I can do this with a dataset but I've never built that before. The fields from the customer will always be the same and the fields I will need will always be the same. Also, the date time has to be in the format of yyyy/mm/dd:hhmm and the phone number always has to have 512 as a prefix. Here is the code I currently have for my site:

I know this is probably a pretty easy thing to do and it is if I can upload the file and store it onto the hard drive of the server. What I need to do is read the text file into memory and then parse through it one line at a time. Anyone have any code that demonstrates that?

My question is how can I avoid this scenario?

I was trying to go through this tutorial:
[URL]
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."
here's my web.config file:

THere is an external ASHX url that dinamically generates an XML file.
I tried to parse this XML using the doc.Load("http://www.domain.com.br/asp.net/integration.ashx") but it haven't worked.
The same code above work fine if I use a XML file instead of ashx one.
I need to read the XML file generated by the ASHX one in order to integrate the websites.

I have a third party CMS system that can create forms but can't manage true File upload capabities. I am able to get users brows for thier file and have the value submited to my custom .net code behind page for processing. So I end up with like "C:somefilefoldersomefile.doc".
But on my processing page I want to read this file (like the file uploader) and save it to a location. I tried using the file uploader control (but have it not visible) but realized I can't preset it as I was planning to set it and do the normal processing from there. Is there another way to do this?
