My Connection string :

I am using above ConnectionString to communicate with database. To make it work, I have to store password (don't want to do that) in session and use it every time I need to talk to db.
1) Is there any other connection string without username and password with oledb?
2) I use "Integrated Security" for MSSQL. How can I use the same with OLEDB - Oracle database?

Without the full path, I can't replace the Data Source by a variable and I definitely can't assume all users will have their Excel files named Book1.xls located in C:Doc all the time.

View 2 RepliesHow to connect to different data providers(Say Oracle and SQL Server) using single connection string?
View 1 RepliesI only made 1 other dynamic page before, without users. I do remember I setup a read-only user to the database and that was the user used in the connection string, simple.
In managing multiple users, does asp.net's membership & roles automatically switch up the databases connection string upon login? Do you setup hypothetical "groups" of user access permissions in your database (mysql) then associate that user to that group in membership & roles?
I'm just looking for a general idea of what to expect before I start reading.
I have 3 Databases that I am pulling data from for my web site. 2 of the databases are in the same SQL instance, however the 3rd one is in a different SQL instance. Both of the SQL instances are installed on the same server, one of them is a Named instance and the other is installed under the default instance. So my connection strings look something like this:
<add name="ABCConnectionString" connectionString="Data Source=BobDataDB;Initial Catalog=Bob;User ID=*******;Password=*********;" ProviderName="System.Data.SqlClient"/>
<add name="BCDConnectionString" connectionString="Data Source=BobDataDB;Initial Catalog=Sue;User ID=*******;Password=*********;" ProviderName="System.Data.SqlClient"/>
<add name="EFGConnectionString" connectionString="Data Source=Bob;Initial Catalog=Sue;User ID=*******;Password=*********;" ProviderName="System.Data.SqlClient"/>
I'm in the process of moving this application from the Development Server to the Production Server when I noticed this issue. Previously the ABC and BCD connectionStrings where pointing to a different server and instance. So my question is how do I get this wo work with the server names being the same but the instances being different?
I have a db connection string 'ApplicationServices' defined in the connectionString section of web.config and 3 Entity Framework connection strings which have the provider connection string attribute with the same connection string as the one in 'ApplicationServices'. Is there a way to reference connectionString in 'ApplicationServices' for the provider connection string attribute of the EF connection string in the web.config, rather than providing the connection string all over again?
View 1 RepliesI am new in Asp.net with Oracle and not build proper connection in it.
View 2 RepliesI have a stored procedure that returns 3 tables within the single recordset it returns. If I set a SqlDataSource to get data from this procedure, it works, but it only returns the first table. I want to have a GridView display the data from the 2nd or 3rd table using a SqlDataSource, but I can't figure out how to specify a particular table.
While there are some posts discussing this out there, I can't get a definitive answer about whether or not this is even possible (?). In a worst-case scenario, I can create another SP that only returns the 3rd table - but that creates a little maintenance headache that I would prefer to avoid.
just for my testing purpose i know i can define both the connection's outside in a single web config file by different name's and access them in my front end according to it but what if i want to have seprate for both connection's web.config situation is like this see image so i want to access my connections from second web config file how i can do that.

I am preparing for an Access2007 db conversion at the beginning of the year and would like to know what the best process would be for connecting to the sqlserver2005 database. I have read about adding the connection string to the web.config file. I have also read about using ADO.NET and put the connection information into a class and not the web.config file.
I would like to hear from others as to what you have used, are using, or plan on using for a webapp (vs2010), and why so I can get an understanding.

My question is, when I want to connect to SQL using a "trusted connection" in the Connection String, what user will actually be passed into SQL?
I thought it would pass my logon details, but it is coming back with an NT AUTHORITYANONYMOUS LOGON error, which seems to point towards it not passing in my logon.
