I just installed the SmallBusiness Starter kit from MSDN. I believe the starter kit by default points to MDF and LDF files in App_Data folder but I would like to use my SQL server instead. Could you please provide me with instructions on how to convert these two files in actuate tables in SQL server?

I need to create a query which does a join between two tables which are in different databases. I can easily connect to each database, and write queries in each, however, I can't seem to find a way of generating a query which does a join between two tables from different databases.

I am storing image (jpeg) files into SQL server 2005 using MS Access Forms. When I try to read and render it on a webpage using ASP.net and C# code behind, it could not read it.
But if I write the image to SQL server using ASP.NET C# and then read it back using ASP.NET C#, it render the image just fine in the browser.
Does anyone know if Access write the blob is difference than ASP.NET write the blob into SQL server? I am using the same varbinary as my column in the database.

from an Access database, I created an Excel spreadsheet. On the spreadsheet I made the adjustments I needed to and then proceeded to use the SQL Server 2005 Import/Export Wizard to import the spreadsheet into a SQL table. I then get the following error message:[Code]....
When I remove the problem columns from the import, then it works just fine. But I really need those text columns! The SQL Server columns that they are supposed to go into are varchar(MAX).

so I know that DataTables are often used as the DataSources for gridviews. Lately, I have found that I can also use generic lists as data sources for gridviews. But I figured that out by simply trying it to see if it worked.
I have looked all over the web and simply cannot find any kind of inclusive list or description of exactly which data structures can be used as the data source for a gridview. Does anyone know if there is such a list, or some kind of reference that I can look to for this info?
Although it sounds like an obvious question, like there is obviously one out there and I just haven't looked, my experience has been that it's just not so.

We are using a tierd design with a Data Access Layer and classes for everything we need. This serves as an advantage because we do not have to write querys over and we can separate the Presentation layer from the Data Access Layer and Business Rules.I have always in the past populated GridViews, DataLists, repeaters,etc with SqlDataSources. This is what I have become accustomed to and I feel like it is simple. For querys such as Select * from Members, I feel like using a DataSource is simpler than having to go in the code and calling methods to populate and DataBind these presentation controls.
I am working with a gentleman who has introduced me to the world of Data Access Layers and we are breaking everything down into simeple, but effective queries to populate controls and do what we need to accomplish with this application. He is not very approving of using any type of DataSource. We are disagreeing on the time and place to use these class methods to call the database.So my question is, which is more widely used in the programming world? Do most people use DataSources to populate presentation controls regardless of the Data Access Layer they are working with? Which type of queries are best suited for a DAL - simple, populating queries or complicated joins and upserts?

I have a stored procedure written using dynamic SQL in the SQL Server and I am calling it on the code behind and adding parameters to it and filling a dataset and binding the data set to a Gridview. But I am getting this error when I bind it.
Can someone please tell me how to fix this?
It used to work fine when I did not use dynamic sql.

I need to display some data in a gridview. Its shipping data.
Part of the data can come from a generic database query. Static shipping data that can be looked up from the database. Part of the data is external and has to be queryed from USPS. Any suggestions on what is the best way to accomplish this.
Should I just programmatically fill the gridview from the code behind doing the database lookup manual and filling the gridview with manual data then going out and filling the rest of the gridview with the data obtained from the USPS service?

this is me once again moving around data access. my problem now hide in the import process of an excel file that would be inserted into sql db.
the problem is the excel file may be updated or changed and i have to periodically import it and perform the process but I still cant check or compare between the two Data Source (excel, sql) as I violate the entity integrity (PK)
i found a kind of stupid approach that each time i want to import the file i will empty the table then re-insert the data, but at this step a new problem raise that other tables are !engaged! with it ... so i will violate the referential integrity (FK)
i looking for solution to compare between two sources for each tuple / row, ignore the existing one and insert the new

I am importing a comma seperated, single quote delimited file based off of client specifications. The only problem is now the client is sending apostophes in the file and is throwing off the single quote delimiter.
For Example:
'FirstName','LastName'
'John','O'Grady'
I need to figure out somehow to escape or replace that character before it goes into my OLE dataset import and then handle it before it hits my SQL table. Here is my current process flow:
Save the file to the App_Data using a FileUpload control Build a schema.ini for the ' delimeter Import into a dataset using Microsoft Jet OLE Use a for loop to pick out the fields that I need and build an insert into SQL I was trying to replace the ' with an underscore but then ended up replacing the whole file instead of just the one in the name.
