At my work we use Trace.Write() and Trace.Warn() quite extensively. The problem is, sometimes the output can be difficult to read with all of the other default trace info written, so we want to be able to extend that a bit and add new colors, bold versions, etc. I had tried the following, but as I've never tried adding to an existing class, I failed miserably.

Presently we have converted a project from vs 2005 to vs 2010,
we have using typed dataset as our business object in separate project
after converting that dataset to vs 2010 dataset, datatable is been changed to System.Data.TypedTableBase<dataRow>,
because of that all project getting error saying method/properties not found default method/properties provided by datatable like select,rows, columns.. etc. are not able to access outside that project, but can be accessed with in that project.
Is there built in methods into .net framework to do the following:
Get role GUID from user name/user GUID
Get role name from role GUID
So far I have been sending queries to the asp_roles and asp_users tables to obtain that information and I'm wondering if there is a nicer way of doing this?
I have the following methods that I store in the ASPUtilities class:
getRoleGUID(guid userGuid) { LINQ joins }
getRoleGuid(string userName) { LINQ joins }
getRoleName(guid roleGuid) { LINQ joins }
EDIT:
I have just looked into extending SQLMembershipProvider examples.
Few examples completely override the SQLMembershipProvider, but I think what I'm interested is just adding few extra methods to deal with the roles by using LINQ. Is this feasible?

1) i have a databse file on microsoft access. and i want to add system date in my databse using c#, what is the method to do this?
2) i m new in asp.net , i m making a demo application and storing a record of a person. there is a column of Date of birth. i used "datetime" data type for this column, because it have check on dates like i can't enter 29-02-2011, since its an invalid date. but problem with that it contain time with it, which should not be mentioned in date of birth column. plz guide me which data type shoul i use?
or if i simply use text data type and then add "regular expression" in textbox, then what regular expression should be used to have a check on invalid dates. remember i m not asking about the format of date, i m asking about invalid and valid dates.
I am currently adding checkbox functionality to a system. I would like to check a group of users and add them into a db table. I currently have the administrator values flowing into the db table fine but it will not insert the empID into the table from the gridview. Here is my code:[Code]....

I have an extension method as follows:
public static class PageExtensions
{
public static int GetUserId(this Page targetPage)
{
var user = Membership.GetUser(targetPage.User.Identity.Name);
return (int)user.ProviderUserKey;
}
}
Now in a page I need to use this method in a static WebMethod, so I have added another 'extension method' to PageExtensions:
public static int GetUserId()
{
return (int)Membership.GetUser(HttpContext.Current.User.Identity.Name).ProviderUserKey;
}
and I call it as follows in my WebMethod: PageExtensions.GetUserId()

View 2 RepliesI am beginner in web applications development. I started one little project and host it on source forge "https://homoco.svn.sourceforge.net/svnroot/homoco". And I started implementing authentication in this application to learn how it works. From my experience people never use out of the box things so I want to implement this stuff alone (like in real world projects). So some questions:
1) Is there any reason to use membership out of the box? To use database table schema, stored procedures etc. that tool generate for developer. I think that this lower control over code and I decided to implement it my self. I don't know if I am right.
2) Is my approach in this demo project good or bad (if someone have time I like to do just a little code review)? I created database based on business rules. Not using database schema that membership provider require. Extend "MembershipProvider" class to satisfy my needs. Implement queries to database myself.
3) Now, this question is a little wired but I have to ask it. If we make custom Membership Provider and do sql queries alone, implement all MembershipProvider class methods ourselves, and in application use Membership.blabla() why is this approach different from not extending MembershipProvider class and putting all this methods in some unique class and call its methods then? I hope that someone understand what I ask here.
I am sorry for three questions, but I really trying to find the best way to implement this feature in my demo project like it is a real world application.

We are developing a web app that will have a pretty complex user and permission system. The general idea is that we have 3 levels of security:
a simple user - that can only access basic data that is in a data repository
a manager - that can open up data repositories
a superuser - that can open up repository factories.
Each repository contains various data types(text, images, etc etc). We are looking for authentication methods that will allow us:
1. Scalability.
2. Customization.
3. To create permissions that will effect the GUI + deny access to certain pages.
4. To create predefined roles - that will allow for easy setup of new users.
5. To create custom roles for specific users - allowing them permission sets that are different from the predefined roles.

Everything was well, uppon the day I needed to format my computer.
And what can goes wrong with a format? I don't know
I have installed the MVC2, I build the project, no error displayed, but from the time I've uploaded the project in the production server
I am getting this error.
