Can we have RoleProvider and MembershipProvider connect to different types of databases?

Posted By:      Posted Date: August 31, 2010    Points: 0   Category :ASP.Net
Say for my ASP.NET application, I have implemented my custom RoleProvider by using my existing Users table on my Oracle 11g database.Then, for my Membership Provider, can I still use the AspNetSqlMembershipProvider that comes with the .NET framework and uses SQL Server?Please share your 2 cents. Thank you.

BCS: Best practice of Toggling external content types between staging and production databases



Environment :
Sharepoint 2010
using BCS to point to external database
create two Secure Store Application ids , one with production credentails and another with staging credentails

I have several external content types (ECT) using an external system(ES) pointing to staging databases.
Now i want to change only one of my ECT to point to production DB but suprisingly the only way i could achieve this was by modifying the ES that all the other ECT are using, this is not practicaly because this makes all the ECTs point to production and not just the one that i want.

Question is how can i have different ES and how can i make only one ECT out of all the ones to point to production, i tried using the "Switch connected systems" but did not like it and below are the details:

Created a new ECT pointing to production which would show the ES being used in BCD services and then i  used the "Switch Connected Ssytems" option under designer to switch the staging ECT to the production ES. Dos the job but the problem is that if there are no ECT pointing to staging ES then it does not appear under BCS services which mean neither can i switch my ECT back to it nor would it be available when i am creating new ECT whch need to point to staging.

Hope i was clear, please suggest how to handle this sit

Connect to two databases.



I've had a site up and running for quite some time with "ASPNETDB.MDF" as database. I recently got a request to make a second site with it's own database, but that also includes a admin interface to manage the first site's database.

"Fine", I thought. "I'll just add a new connection string and point to the first database.". But unfortunately it seems to involve a few more steps then that.

My connection strings are:
<add name="ASPNETDBConnectionString" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\ASPNETDB.MDF;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient"/>

<add name="myfirstsite_ASPNETDBConnectionString" connectionString="Database=myfirstsite_aspnetdb;Data Source=.\SQLEXPRESS;AttachDbFilename=C:\\Inetpub\\myfirstsite\\App_Data\\ASPNETDB.MDF;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient"/>

But whenever I start up my first website I can't access the database through my second one. I just keep receiving the error:
"Cannot open user default database. Login failed.
Login failed for user

SharePoint Tutorial - Content Types

SharePoint content types provide users with a way to manage and organize content in a more meaningful way. It's a reusable of settings you want to apply to a particular type of document in a library or item in a list.

Writing custom MembershipProvider

ASP.NET Membership mechanism allows to use the build-in server tables to store and retrieve user data. By default, this mechanism can only be used with SQL Server database to which Microsoft provides suitable MembershipProvider class.
Inheriting from this abstract class, developer can use his own table(-es) from any database and use any database engine other than SQL Server, like Oracle, DB2 etc.

UML Diagram Types

UML provides a number of diagram types as a mechanism for entering model elements into the model and showing overlapping sets of models elements and their relationships. UML does not specify what diagrams should be created or what they should contain, only what they can contain and the rules for connecting the elements. The diagram types include:

UML Diagram Types - 2

Further diagram types include:

Activity Diagrams - a generic flow chart used much in business modelling and sometimes in use case modelling to indicate the overall flow of the use case. This diagram type replaces the need for dataflow diagrams but is not a main diagram type for the purposes of analysis and design.

Ready made List Types provided by SharePoint

SharePoint provides some out of the box List Types. Some of the most used ready made list types that SharePoint provides currently are listed below:

Tuples, Anonymous Types, and Concrete Types

Tuples can save you a great deal of repetitive tasks. They can also lead to completely unreadable code in a language like C#. Tuples are data values that contain N items. The .NET framework supports tuples containing 1 to 8 members. To use tuples with more than 8 members, you use another tuple for the member of an octtuple

Content Types in MOSS 2007

In this article I will try to describe the one of the best feature in Microsoft office Share Point 2007 called Content Types.

Content types are simply collection of contents.Each content in a Content type can have different settings.Basically it is a reusable collection of settings which you want to apply to a particular category of contents.

Data Types - Date and Time in SqlServer

Date and time values can be stored with either the DATETIME or SMALLDATETIME data type. The difference between the two is that SMALLDATETIME supports a smaller range of dates and does not give the same level of precision when accounting for time. The DATETIME data type can hold values from January 1st of 1753 to December 31st of 9999. The time is stored to the 1 three hundredths of a second and each value takes up 8 bytes of storage. The SMALLDATETIME data type can hold values between January 1st 1900 and June 6th of 2079. The time is tracked to the minute and each value takes up 4 bytes of storage. The majority of business applications can live happily with SMALLDATETIME, however, if you are in an environment where each second matters or you need to make estimates to the distant future (or past) then you have to resort to DATETIME. If you fail to specify the time when inserting a value into a DATETIME or SMALLDATETIME column, a default of midnight is used. If you fail to specify the date portion the default of January 1, 1900 is used.

Frequently Asked Questions - SQL Server Data Types

This is good and precise introduction and Frequently Asked Questions - SQL Server Data Types

could somebody give me example how I can connect to database only once if I use many models in contr


I use in my ASP.NET MVC application repository pattern and I use in controller for example 3 models:

   namespace MvcApplication1.Controllers  
        public class HomepageController : Controller  
            private IWebsitesRepository _repository_websites = new WebsitesRepository();  
            private IFirmRepository _repository_firm = new FirmRepository();  
            private IPhotosRepository _repository_photos = new PhotosRepository();  

In WebsiteRepozitory, FirmRepository and PhotosRepository classes I have:

Database1Entities _entities = new Database1Entities();

So I have 3 connections to database ? Is it wrong ? How can I solve it ?

How do I persist custom complex types in design-time


Let's say that I've got one custom webcontrol called MyControl.

public partial class MyControl: WebControl {
public IComplex Complex { get; set; }

The control is a very simple control but it holds an instance of a complex type that is accessable through a property. The property has the propertytype IComplex

public interface IComplex {
string Name { get; set; }
List<IComplex> Children {get;}

Let's say that I am able to pick one of several different types of object that derives from IComplex in design-time and assign it to the controls property "Complex" property.

Naturally I would like to persist this information to the HTML-View in a user-friendly way.

Because we don't know what type the user has picked there is no way to instansiate the type if we don't persist the name of that type. The Type could also contain more properties than the Interface the controls property is refering.

<cc1:MyControl id="MyControl1" runat="server">
<Complex> <!-
