Asp.net - Crystal Reports Viewer: Failed To Open The Connection Error
Jun 19, 2012Currently I'm working on a piece of code that involves using the Crystal Reports Viewer to export .RPT files to PDF. My problem is that the code works on literally everything except the website I'm planning to eventually put it on.
When placed on the website it throws back the error "Failed to open the connection." which I believe is connected to the SQL Server connection that's formed in order to read data for the report itself.
The code itself is solid and works when used in a separate console application I built to test it whether said code is run on my local machine or on the server itself. It even runs when I test the website in Visual Studio's virtual host.
I've narrowed it down to being some sort of permissions issue, but I am not knowledgeable enough in the various permissions settings to figure out which ones specifically apply to this situation. It's worth mentioning that other pages on the website are directly connecting to the same database, but they are doing so directly through Linq instead of going through the Crystal Report Viewer.
So does anybody know which settings I need to modify in order to fix the connection error.An added note: One of the other suggestions is to make sure there's an ODBC DNS in place that matches the one being used by the code. I have created such a DNS already.

View 2 RepliesUniversal Way To Connecting To Excel Through OleDB Connection?
Nov 17, 2011A While back I developed a application that connected to Excel using DB connection. It worked fine since the application was designed for usage on one particular PC with Excel 2003. I especially liked the solution since the data retrieval was much faster compared to what I would get if I connected to Excel using Interop libraries.
However, recently when I tried to implement the same solution onto another app that would run on various PC that could use different versions of MS Office I ran into multiple problems. First of all, I can't use the same connection string on various versions. Also, the whole x64 vs x86 thing is adding to the problem.
I wonder if there is a way to check the version and use the apropriate connection string for every version?

Asp.net - Reading CSV File With OLEDB Ignores First Line Even With HDR=No In Connection String?
Jan 4, 2011We'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;""")
[code]....
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.

Make An Oledb Connection To An Access Database : Invalid Authorization Specification
Sep 15, 2007I am trying to make an oledb connection to an Access database.
1. I added a component class.It said drag from the toolbox to add components.
2. I dragged over the Oledbconnection and OledbdataAdapter
3. I clicked on new connection string for the oldeb Connection and try to connect to the SHX.mdb datababase in the debug/ bin folder I don't have a username or password for the database and do not want to set one up.( is this possible in .net?)
4.As soon as I try to test the connection, I get the "invalid authorization specification" message. I can't get past this and do not really understand why I am getting this message.I have vb 2005 standard edition, not express edition.The exact same thing happens when I try to set up the data adapter to the shx.mdb database.
I am on XP2 and not logged in with a password or username. Could this be the issue or is there something else I am overlooking.Also, since I am coming from vb6 and ADO is there anyway to just write the code without having to use datasets, adapters and oledb connections to bound controls?
