Need help with setting up data connection in ADO.NET. Checked message
boards but have not found solution. Any help would be appreciated. Here is my situation: BACKGROUND: I'm using Visual Basic.NET Standard 2002 on XP Pro running MSDE (the one that came w/ Visual Studio). Here is the problem: when setting up a data connection, I am able to see the MSDE SQL server running on my local machine form the Server Explorer. The connection seems just fine, since I can browse all tables, see all their contents, etc. The problem begins when I try to creat the ADO.NET connection. I drag one of the tables onto a form, and VS begins generating the connection code. However, an error comes up and reports that "SQL Server does not exist or access denied". Afer investigating, I've tried the following changes to my connection string settings, but to no avail: 1. VS configured the SQL Server on my machine (SJ-CGONZALEZ) with the following name SJ-CGONZALEZ\VSdotNET. I edited the connection string to include an escape character for the "\" that appears. In other words, connection string became: data source=SJ-CGONZALEZ\\VSdotNET. It didn't work. 2. I tried using named pipes instead of tcp-ip, adding the following to the connection string: net=dbnmpntw. That didn't help. 3. I tried doing points 1 and 2 a the same time, but it didn't work. What should I be trying next? Any help would be greatly appreciated. Thanks, Carlos |

Hi,
What do you mean "data connection"? Is it same application? Is it ASP .NET application?

Val,
I am trying/learning to make a Windows Application that will connect to a database. What I mean by "Data Connection" is that the Server Explorer within Visual Studio is able to see and explore my SQL server (on local machine). That leads me to believe that the config problem is not with my server but with the VB code in my application. The problem begins when I try to generate the VB code so that my Application will be able to make the connection, create the data adapter, and then generate a data set. I let Visual Studio generate the connection code (connection string, etc.). The problem, I assume, is in the code that is being generated. That is why I have tried the two changes I detailed in the original email. Also, I've tried changing the login from Windows Login to SQL Login, but have had the same problem present itself. I'm a bit of a beginner at VB.NET, so I appreciate your patience and help.

Hi,
Could you post full connection string? Actually you should not escape \ character. This way SQL Server distincts named instances -- Val Mazur Microsoft MVP "Carlos Gonzalez" <cagonzalez@yahoo.com> wrote in message news:#mzEUNyPDHA.1748@TK2MSFTNGP11.phx.gbl... > Val, > > I am trying/learning to make a Windows Application that will connect to > a database.

Val, this is the full connection string: "data source=SJ-CGONZALEZ\VSdotNET;initial catalog=Holdings;integrated security=SSPI;persist security info=False;workstation id=SJ-CGONZALEZ;packet size=4096" Like I said, this is generated by VS automatically. I've tried different configurations (SQL login, Named Pipes), which result in different connection strings, but none have worked. Thanks for your help! -Carlos *** Sent via Developersdex http://www.developersdex.com *** Don't just participate in USENET...get rewarded for it! |
