Using OleDB, I want to access the hyperlink part of the cell but I'm stumped because I can't figure this out. Here is what I have thus far.

The hyperlink is in the Number field. So using OleDB, can I do this?
The attached code, the oledb part, is giving me a blank web page saying it cant connect on my local dev server. I have another app with the same code, in fact I copied it and changed the db names. The one I copied from works fine.

View 8 RepliesWe'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?

We're trying to get connection pooling working with uodotnet and currently failing miserably. When we turn connection pooling off everything works as expected, but when we turn it on we often get timeouts or errors with one of the following trace outputs:
2011-03-28T15:09:28 System.Exception: Non-negative number required.
[Code]....
Not all the requests fail (for example, when run through a load testing tool, 7/20 requests failed with the timeout problem).
It seems that the sessions are remaining in the pool and new attempts to create a session are repeating until the timeout limit is reached (30 seconds). We're using uodotnet.dll version 2.1.1.7196 and UniVerse version 10.3. running on an HP-UX server. We've got a single license on the dev machine we're testing on with 10 connections available in the pool (theoretically!). We're writing an ASP.Net web site, and we create a new session in the Page_Load() event which is passed to all UniVerse routines and then call close on the session in Page_Unload()/Page_Error().
to what we're doing wrong? We expected that connection pooling would improve performance, falling back on the standard mechanism if the pool was full, but whereas the non-pooled version works fine with 20 simultaneous requests, the pooled version regularly fails. We've set the connection pooling on in the application's web.config, setting MinPoolSize to 1 and MaxPoolSize to 10, leaving everything else at the defaults.
What is the difference between connection timeout and command timeout?
In our application sometimes it is showing a timeout error. When we increased the command timeout value to 100(from default 30), its working. Is there any issue in increasing the command timeout value.
We have been getting this Oracle connection pool exception a lot recently for our ASP.NET website. This is the detailed exception message:
Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached.
This is our connection string
User ID=user1;password=password1;DATA SOURCE=Datasource1
how to set max pool size to 1 so that I can debug it on my local?
what is the recommended pool size for a website with 10,000 users?
Alright, we have two database servers, one is owned by us, one owned by a partner. Our partners have been having issues lately that have been causing us numerous sql timeout errors, which takes down our whole system. We'd prefer to limit the time those queries can take to say 20 seconds max, otherwise quit trying and throw the error (which we can catch with a try/catch block). Couple of questions: Is there a way to set a particular db/connection string to timeout after X seconds? Is this the best way to quarantine that other system? or are there better ways to go about this?
