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?

We're converting a Classic ASP site to an ASP.NET site. One function was to upload a 'template' of data in CSV format for importing into the database. There were several different record types in there (the first field always indentifies the type of data).
The task was to get the CSV into a DataTable so it could be validated (new project is to have MUCH better validation rules)
The code seemed pretty straightforward - watered down (taking out comments, Try/Catch, etc) it is as follows:
Dim da As New System.Data.OleDb.OleDbDataAdapter
Dim cn As New System.Data.OleDb.OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & strDirectory & ";" & "Extended Properties=""Text;HDR=No;FMT=Delimited;""")
Dim cd As New System.Data.OleDb.OleDbCommand("SELECT * FROM " & strCSVFilename, cn)
cn.Open()
da.SelectCommand = cd
da.Fill(dtData)
The DataTable (dtData) is populated, but only starting with the second line of the CSV file DESPITE the fact that "HDR=No" is in the connection string. What am I missing here?
I have an input type, so a text box which has a browse button next to it. When it is clicked, the file that is selected has it's full path placed into the text box.
<input type="file" runat="server" id="txtFilename" style="width:400px" />
Where is the event!
Now that I have the path to the file in the textbox of the input type, I want to load each line of this file into a textbox that is able to handle multiline text.
I don't want the file to be uploaded to the website. I just want to contents of the file read and placed in a textbox all with one click on the browse button.
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."

1. I know about collections but I dont remember the precess. I know you drag a sqldatasource control on the form(Select everything in the database ie. selct *) and then delete it. But how do I use it i code.
Example. I need to select services where country=canada from the Agencies table.
2. I know how to manually pull data from an access database using the code below. I want to know how to pull data from a sql database just like the one below.
3. explain the difference between Collections and manually pulling it like the one bellow?
<code>
<script>
Stringpath = Server.Mappath = Server. MapPath(/website");
String connStr = Provider=Microsoft.Jet.OLEDB.4.0" +"DataSource="+path+

conn.open();
OleDbCommand cmd= new OleDBCommand();
cmd.COnnection = conn;
cmdCommandText = "Select * From [Suppliers];
OledbDataReader dr= cmd.ExecuteReader();
Response.write(dr.getvalue(1);

View 3 RepliesI have a webform with 6 controls (3 drop downs, 2 text boxes, 1 file upload box). User makes selections, chooses a pdf file to upload, then clicks on a submit button which uploads the data and pdf file to a SQL database. Everything works good up to this point, data is uploaded, pdf is sent to database as binary data. Problem is that I can't seem to figure out how to get the form to "re-read" (for lack of a better word) the database, it looks as though a new record was not inserted although it was. There is a field for "ID" that shows what the record ID will be (the next greatest number to the previous record) and that field does not increment unless I stop running the web app and restart. I've included the code behind for the button_click event:

View 1 RepliesI have a CSV file (with semicolon field separator) of 150MB (about 2 milion rows and 35 columns).
Now I want to loop through the CSV per row and get each row column.
I am trying to read a text file from the root of the server. This is what I tried
Code:
Dim sr As StreamReader
Try
sr = File.OpenText("~ est.txt")
Label1.Text = sr.ReadToEnd
Catch ex As Exception
Label1.Text = ex.Message
End Try
If I test this locally, I get the error: "Could not find a part of the path 'C:Program Files (x86)Common FilesMicrosoft SharedDevServer10.est.txt'."If I upload it and run the code on the server, nothing happens (Lable1.text does not change).
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?
