I want to use Full SQL Server 2005 as a data store for my role provider. I installed the aspnetdb using the wizard. in my application I added the following connection string
<connectionStrings>
<clear/>
<add name="LocalSqlServer" connectionString="Data Source=localhost;Initial Catalog=aspnetdb;Integrated Security=True" providerName="System.Data.SqlClient"/>
</connectionStrings>
then I configured my role provider as follows:
<roleManager enabled="true">
<providers>
<clear/>
<add name="AspNetSqlRoleProvider" connectionStringName="LocalSqlServer"
applicationName="/MyApp"
type="System.Web.Security.SqlRoleProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
</providers>
</roleManager>
I create roles programmatically like this:
if (Roles.RoleExists("RoleName"))
Roles.CreateRole("RoleName");
but when I check my aspnetdb from the SQL management studio I found that the table aspnet_Roles has no records and that the roles where not inserted. so is there anything wrong with these steps or something missing ?

i need to save multiple documents stored in SQL server as Image type to disk.
What i want to do is "backup" all files in a table (column) to disk, zip them and Response.TransmitFile(FilePath) to client.
I could use C# ot VB but that would require a lot of connections to database or a lot of server memory and i don't want that, becauze there are a lot of files to be saved Since SQL can write files to disk i was thinking about saving those files to disk directly from sql. Something like when u're doing a backup

i have a website written in asp.net c#. it was using a sql 2005 db but due to requirements we have ensure it's compatible with a sql 2000 db. everything on the site converted ok except for one page that is using a stored procedure to read in a marquee. the @Url_FK variable is no longer being passed to the page via the stored proc.
The only difference in the table design is 2005 uses nvarchar(max) and 2000 uses varchar(8000) for the TOD_Text field.

View 5 RepliesPassing a null or nothing value to a datatime datatype database field (Access)
I've been all over the internet looking at this and I have tried dozens of methods without success.
I've read a few forums where, some say you can not assign a null value or a nothing value to a datetime datatype field. Then I see others where they say...'I got it to work'.
If this is true (that you can not pass a null value), how come I can create a record in the Access table and not assign a value to this date field? (The field is defined as not required).
Yet, once a value is in the field, I can not update that field back to a null or a nothing value.
So I'm hoping someone has the definitive answer to this.
I am using VB.Net Vs 2003 and updating an Access data base.
I have an update statement (see below) that uses parameters for updating.
what will work, so that I can put back the null or nothing value?
Or if it really can not be done, I guess I'll have to take that as truth.

specify a querystring to be always null when there is no value to pass?I always get an error saying NULL can't be converted to INT.The SQL datatype for this querystring is int.
