hi every1,
i m beginner in asp.net I have watched tutorials on Role base security and trying to implement it.In aspnet database (same database uses for default web sercuty) i added a simple student table with two cols (UserId, UserName) then made a one to one relation between aspnet_User and Student. when i created a user through Asp.net configuration. I found that UserId has been added into both aspnet_users and aspnet_membership tables but not in Student table. please could u explain me how i can add same userid in student table as it has been added in users and membership table. if i cant save UserId in any other table at all then pleas tell me how i can add student data like(CourseId,startdate) wit same user Id. I ll really appriciate ur help.

This seems like a complex task for a beginner, are you teaching yourself ? You should start with something simpler.

u have to add the UserId in 'your' table yourselves ...

thanks for your answer, but I'm sorry I have just realized that I should explain my question properly actually I have three roles in my database CourseTutor, Supervisor, and Student. I want to maintain Student data for this strong reason I need all UserIds' which belong to student and it should save into student table. (I want to work on StudentIds' rather than their names). Is this possible to get all those UserId's which related to Student's role, from Stored procedure.

u need not store roles and userids separately ...

while registering users, assign a role to them ...
now to store personal info, create a table with columns about UserId,name,address etc ....
in the CreatedUser event handler, add a row in this table ...

to know the role of any user, u can use
Roles.GetRolesForUser("<username>");

u can use,
Roles.GetUsersInRole("<rolename>");
to get all the users in a particular role ...

I really appreciate that you gave me the exact answer what I'm looking for.
thnx again. actually I was doing the same as you have mentioned like register a user form Asp.net configuration and assign them roles. but I wasn't sure how to store all UserId's which belongs to Student's role into Student table as well.

I doubt that.

You identify the radiobuttons by name. You cannot set the client side id, but it's generated based on the server side id, and if you want to identify it on the client side, you can create js variables that map to the client ids. You can also set tags to identify them.

Do you have programming experience ? You could write a VB.NET application that would open the Excel document, loop through the rows and create INSERT statements to your SQL server.

Hi,
I have a link my aspx page and onclick of that i need to download
and run the msi(ie i need to run a command in client like "msiexec /i http://(servername)/(virtual directory name)/test.msi ALLUSERS=1" )
which is present in the webserver(IIS 5 or IIS 6)...(it"s an intranet application)

as of now im giving the path of the msi to the link ....but the requirement is to
run msi using msiexec so that we can even perform passive installation...

Please help me out .....and correct me if im wrong

Re: Run msi

It can not be done. IE will not allow you to execute the msi file. You have two choices
1. write an activex code and with permission from the client you can execute what ever you want. But this only works on IE and you need the client to give you permission
2. Let the client download the msi file and give them instructions in your page how to execute it.

Imagine if someone can write malicious code and use IE to execute it, that would be huge security hole.

Hi,

First, note that it uses a named instance (SQLEXPREESS) , so when you try to connect the server you need to specify all (SERVER\SQLEXPRESS)

Second, it is using Integrated Security, so, seems you dont need any specific user/password information.

And yes, the database name is : abc

Use server explorer of visual studio/database explorer of visual web developer

Right Click Data Connections -> Add Connection

Server Name= IP Address of the remote server [must be static IP]
SQl Authentication:
User Name = type in user name who has authentication
Password = type your password

Click on Test Connection, it will work.

If test not succeed then try to ping the IP Address from command prompt. If not pings, its networking fault. and if it works then check permissions of the server.

Try this...

Replace the values for user and active directory group.

DirectoryEntry ent = new DirectoryEntry(appSettings.domain, appSettings.user, appSettings.password, AuthenticationTypes.ReadonlyServer);

DirectorySearcher srch = new DirectorySearcher(ent, "(CN=" + activeDirectoryGroup + ")");

SearchResult obj = srch.FindOne();

DirectoryEntry dr = new DirectoryEntry(obj.Path, appSettings.user, appSettings.password);

foreach (object ob in (IEnumerable)dr.Invoke("members"))
{
DirectoryEntry obGpEntry = new DirectoryEntry(ob);
//Put your code here.
}
