Can't Insert A Guid (userID) Into Table!
Feb 10, 2011
I'm creating a web project for one of my uni modules using Visual studio 2010. I'm using asp.net membership and have all of my sql-server tables set up correctly (I'm pretty sure).
I have a form that I have created myself that inserts into the database using sqlDataSource.insert(). I had some problems initially with not being able to insert any data into the table at all, but I have cleared that up.
My problem now is that I need to insert the currently logged in user's userID into one of the columns of the table. But every time I hit the submit button, I am told I cannot insert null values in the userID column.
I can retrieve the userID using this snippet:
[Code]....
This is the code behind for the page:
[Code]....
As you can see it is a bit of a mess, I've been frantically trying different variations, as I need to catch up a little with other uni modules.
Here is my SQLDataSource from the .aspx page, The controlparameters work fine for the other data I am inserting. maybe the <asp:parameter name="userID" /> is wrong?
[Code]....
I'm relatively new to vb, and I come from a html & css background.

I'm trying to insert userid that is a System.Guid into an additional table into the same userid field that is uniqueidentifier. It seems as it cannot insert the System.Guid type there wether I'm passing it directly as the System.Guid or as a String then converting.
<System.ComponentModel.DataObjectMethodAttribute _
(System.ComponentModel.DataObjectMethodType.Insert, True)> _
Public Function InsertUserInterests( _
ByVal strUserId As String, ByVal strCode As String) _
As Boolean
Dim userInter As New DS1.tblUserInterestsDataTable
Dim userInterRow As DS1.tblUserInterestsRow = userInter.NewtblUserInterestsRow
Dim ug As System.Guid = New Guid(strUserId)
userInterRow.UserId = ug ' This didn't go through I beleive
userInterRow.InterestCode = strCode
userInter.AddtblUserInterestsRow(userInterRow)
Dim rowsAffected As Integer = Adapter.Update(userInter)
Return rowsAffected = 1
End Function

I'm using ASP.Net/C# and I have a form that allows people to add information into a table and along with it I want to collect the Current Users GUID and insert it.
I have a field setup (UserID) as a unique identifier and I have the following code:
protected void Page_Load(object sender, EventArgs e)
{
MembershipUser currentUser = Membership.GetUser();
Guid temp = (Guid)(Membership.GetUser(User.Identity.Name).ProviderUserKey);
Guid @currentUserID = temp;
}
SqlConnection con = new SqlConnection("Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\ASPNETDB.MDF;Integrated Security=True;User Instance=True");
SqlCommand cmd;
protected void Button1_Click(object sender, EventArgs e)
{
con.Open();
cmd = new SqlCommand("insert into Accom (UserID) values('" + @currentUserID + "')", con);
cmd.ExecuteNonQuery();
}
I basically want to link the variable to the Database how as the above gives errors.

I recently read Scott Mitchell's article series "Examining ASP.NET's Membership, Roles, and Profile". In Part 6 [URL] It says "to store additional, user-specific fields...If you are using the SqlMembershipProvider, this would mean creating an additional database table that had as a primary key the UserId value from the aspnet_Users table and columns for each of the additional user properties."
I created a table named Thread to store some specific users information and comments they make. I set the ThreadId as the primary key and the UserId as the foreign key to the UserId in aspnet_Users table. But when I run the application and use a user's account to submit a comment, there is an error in my Comments.aspx.vb page "Cannot insert the value NULL into column 'UserId', table 'ASPNETDB.dbo.Thread'; column does not allow nulls. INSERT fails.The statement has been terminated."
How can I make the logged-on user's UserId inserted into the Thread table when storing the user's other data information?

We have a system where an administrator can login and create other users. If the administrator creates another user, then logs out and immediately logs back in with the new user information the UserID Guid is not available. If you log out and login again with the new username it works, or if you simply refresh the page it works.
Why does it not work on the first run?

So I'm almost finished my project but I'm stuck. In my application's database I save some records that contain the currently logged in user's userID - and so when it comes to displaying these records, I've been just been outputting the userID whilst developing the rest of the application. Through googling I've found this line of code that will get the a username based on a userID:
Dim membershipUser As MembershipUser = Membership.GetUser(New Guid(userGUID))
Which works great if I can supply it with a GUID - but I'm struggling to see how I can use this line of code if for example I want to show the usernames for comments on an article which are contained in a repeater control.Maybe it would be simpler to just merge my application's database with the asp.net membership database (ASPNETDB.mdf) so I can just select the username in SQL instead - but I'm not even sure how to do that.

It sounds pretty simple, but I can't find a way to make it work. I have a FormView with a InsertTemplate where it inserts the current logged in user's UserId and content from a HTMLeditor, and a EditTemplate where it retreives the current logged in UserId and shows content from database in the HTMLeditor.
How can I get it to show EditTemplate if the userId exist in the table, and InsertTemplate if the UserId does not exist in the table?

I have followed this tutorial which provides me with Membership, Role, Profile etc.

Everything is working fine, but I noticed that the userid is in standard INT, not GUID. Is it possible to get around this? I want the userid as GUID.

I want to assign Guid to UserId of my UserDTO if UserId is Null. Is it possible to do this in the CreateMap or creating any formatter?. I am using automapper as an attribute on my Actions in controller.
protected override void Configure()
{
Mapper.CreateMap<User, UserDTO>()
.ForMember(d => d.FullName, o => o.MapFrom(s => s.FirstName + " " + s.LastName));
}

I have a confusing question, I have a user table and it stores all the usual data for a user that you would expect but im trying to figure out how a user could add another user?
Sounds strange but each user in the User table has his own UI which is UserID how could I add another table where UserID can have a relationship with another UserID?
i.e how would I right the syntax for the above question if I wanted to display all the UserIDs friends on a page. How would I add a friend.

I have a page with a gridview that is populated depending upon the value of the querystring passed to it - there is a one-to-many relationship between Jobs and Locations respectively (one job can have many locations), and the gridview is a list of Locations that are associated with a particular Job. So far so good.
I have a DetailsView below whose DefaultMode is Insert to add a new location, though I can't seem to capture the JobId (guid) from the querystring. I've tried the following code on the Datasource's Inserting event:
[Code]....
but on both occasions I get the same error: Foreign Key constraint broken on JobId field. It seems that the querystring is not being passed to the datasource for inclusion in the insert.

I created the Table Profile Provider with the VB.NET and it works perfectly but I have one issue with it.. My Table (UserProfile) can't be linked with any other tables because the UserID on userprofile is different than any other table yet when I do profile.firstname on the vb code it works perfectly. Say for example I have a username called john If I do select * from aspnet_users where username = 'john' The results would come to 2 rows, 1 which has a userid and applicationid that is used on ALL the tables in my database EXCEPT for userprofile The second one would have a applicationid and userid that is only use on my userprofile table.

There are lots of posts about this issue but I can't work out the answers as most of them are for C# or similar. I'm trying to automatically insert the UserId generated by Membership into a custom table. I have membership working correctly, as well as the custom table (I'm able to insert other things from the registration form). But I can't get it to extract the generated UserId and insert it into the custom table. Here's my code:
[Code]....
As you can see I've experimented with the parameters for inserting the record, but that doesn't work (I get an error about ProviderKey not being a part of system.web.security.membershipuser).

Perhaps this is a simpler VS9 question, but I want to link a SQLServer table with additional user data to the standard SQLServer membership table using the GUID userID as a foreign key. I go into design mode of my table, right-click on relationships, and click add in the dialog. but the left hand column shows me only the tables in my database. How do I get it to show the tables in the ASPNETDB.MDF database? I went through the tutorial (http://www.asp.net/learn/security/tutorial-08-cs.aspx), but it seems to magically appear in there without explanation.

I get this error while trying to run my project: "Column name 'UserID' appears more than once in the result column list." Indeed, the query generated in my SqlTableProfileProvider.vb is the following (text in brackets [] has been changed):
"IF EXISTS (SELECT 1 FROM [table] WHERE UserId = @UserId) BEGIN UPDATE [table] SET UserID=@Value0, LastUpdatedDate=@LastUpdatedDate WHERE UserId = '[Guid]'END ELSE BEGIN INSERT [table] (UserId, UserID, LastUpdatedDate ) VALUES ('[Guid]', @Value0,
@LastUpdatedDate) END"
I'll emphasize that the above statement is generated in SqlTableProfileProvider.vb, which was written by .Net people. While I have little control over its source, I've apparently given the fodder whereby the mistake can be generated. Any clues as to why UserID is being written twice in the statement?
