I'm identifying a logged in user. I use this code:
[Code]....
[Code]....
When I go to insert form data with LINQ to SQL, says it can't due to string not a unique id.
I realize that user names are unique, but is there another identifier associated with the username? If there is, how do I find out what it is for the user who is currently logged in?
View 2 RepliesI am just wondering how do I get the very last row of a join statement if I don't have any unique identifier... as in row_number field?Is there a way of creating a dummy column on my SQL statement to hold the record numbers of all records ..[1 to n] etc ???Id like to know how to do this and then I can get the MAX record number.Im using SQL server 2005 so the last() function doesn't work.
View 3 RepliesI'm creating a website with sql server db (built in membership database). I design it best possible. Im reluctant to use text fields as identifiers, but this is pretty much my first sql server db.
1. The user registers himself, at the same time registering his company/organisation. I dont think many of them will have the need to register themselves to other companys (N:N) but you never know (anyway not a main concern at the moment).
2. This user becomes a superuser (level1), with the ability to register other users to the same company (level2 users). Finally level1 can register level3 users to the same company.
So you see the identifier will be everywhere in the sql commands. There are quite a few N:N relations as well, which I guess slows it down even more. The selections typically retrieves a few hundred to a few thousand posts, but like I said, many will be in N:N relations.
I'm going to write my own Authentication module and I need a unique identifier base on users requests header , I think [(user IP)+(user Agent)] can be reasonable but I know it's not completely safe do you know any other options or methods?
View 3 Repliesin the code in front i have:
Code:
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:SQL2008R2_799650_xnacsConnectionString %>"
SelectCommand="SELECT [ArticleTitle], [articlehtml], [submittedby], [datesubmitted] FROM [Articles] where articleid ='@id'">
</asp:SqlDataSource>
and code behind is taking a url param (guid) and passing it to the select above
it looks like this:
Code:
protected void Page_Load(object sender, EventArgs e)
{
string id = Request["article"];
as simple as that, the problem is the page falls over saying it cannot convert string to Unique identifier, I'm new to asp.net but not c# so there are a few bits i'm trying to get my head round..
First of all here is my code chunk.

Right now I am creating this session with the session key "PhonePart" which is also the name of object I am passing in as a parameter in first method. In subsequent methods, I use the the same name to retreive and clear session value. My problem is, this approach works fine If I instantiate a single object of the class where these methods are defined and using that object call the methods, but when I create another instance of the same class and calls for instance method AddToSession and pass that instance, it overwrites the session value stored by the first instance of the class as the session key is the same that is "PhonePart".
Considering this scenario, is it possible that I somehow grab the name of the object as string in the calling method say "AddToSession" and create a session with that name? If Yes, then I can do the same in subsequent methods and retreive session value and also clear the session specific to that instance name without affecting the other session values stored by other instances.
i have a web application with form identification agains ActiveDirectory. The user is added to the aspnetdb and then we add his roles and profile.heres my question. If you have a user with "abcdef" for his sAMAccountName and then this user quit the job and someone else came in and we give him the SAME sAMAccountName, how aspnet will react? i guest it will see that the sAMAccountName already exist in the aspnetdb and will use it? if its true, then i will have a problem that the new user will inherit the old user access and profile!how can i solve this? i know theres a objectGUID attribute in AD that i can use but how can i use it with aspnetdb?

It should happen for each entry we make through asp.net page. I mean for each time when the page loads it should create this unique number.
I'm using a ListView and have two buttons that allows users to delete or edit a item from the list. Below is the code for the buttons:
<td>
<asp:ImageButton ID="ButtonEdit" runat="server" ImageUrl="~/Styles/Images/Edit.png" ToolTip="Edit" OnClick="ButtonEdit_Click" />
<asp:ImageButton ID="ButtonDelete" runat="server" ImageUrl="~/Styles/Images/Delete-Red-Cross.png" ToolTip="Delete" CommandName="Delete" />
</td>
When the user clicks the edit button I want to pass the unique identifier from the item in the list to the parameter string so I can retrieve it in the edit page. how to retrieve the ID from the selected item?
I'm using Visual Web Developer Express 2008 and SQL Management Studio Express 2005. I need to link 2 tables to either present in a Master/Detail or GridView/Form view.The goal is to allow the user to view time card information from the AS400 (read only) and then enter any corrections into a SQL table. My problem is in trying to connect the two tables.I've asked the AS400 administrator to add a unique identifier field to the table (HAPOINT), but he says he can't. I've tried to concatenate a field within Visual Web Developer's Query Builder but keep getting errors.Table 1 - exists in AS400, is non-permanent (cleared every 3 months) and can't be modifiedEmpl ID WO Date In Time In Date Out Time Out Table 2 - exists in SQL Server, newly created for this project (no data yet, so can be modified)Rev ID Empl ID Date (of revision entry) X (Revise - y/n) Revised Time In Revised Time Out I tried finding a solution through the SQL Forum, but haven't gotten a solution, so I'm posting here. There are additional details at that post:http://forums.asp.net/p/1516929/3658517.aspx#3658517Can anyone tell me how to concatenate "Empl ID /WO / Date In / Time In" from Table 1 to produce a unique identifier that I can then use in Table 2, thus providing the link between the two tables? Or, is there another way?
View 8 RepliesI need to generate a Unique Reference number that has 7 digits.
It should be formatted in the following way:
1st: B (Ball), G (Gift), C (Cat)
2nd: represents year of booking A(2010), B(2011),C(2012), etc
3rd: represents the month of booking J(Jan),F(Feb),M(Mar),A(Apr),Y(May), U(Jun), L(Jul),G(Aug), S(Sep),O(Oct),N(Nov),D(Dec)
4th: days of booking A(1st) - Z(26th), 1(27th) - 5(31st)
5,6,7th: These are counters for the number issues each day. Each can be A-Z,0-9 giving a total of 46,656 combinations. So 0 is first, then 1, 2, 3, 4, 5, 6, 7, 8, 9, A-Z, then 00 to 0Z, then 10 to 1Z, then 20 to 2Z, etc
Now , the 1st Digit is a Character that I generate based on a condition and that shouldn't be a problem.

View 1 RepliesI need a way to create unique values for a property in my custom server control..
In this case I will have the poroperty called "Name" and I neeed the value of Name to be unique for each "instance" of the control...

I have a sql server 2008 database table that has a column of type geometry. I am trying to update the data for a record. The data that needs to be inserted into the database is a POINT location that i get off of two text fields on an .NET form. I pass the values into a procedure to update the record. Below is what I have been trying with no luck. The @lat and @long variables I pass into the procedure as type. Does anyone have a good way to update this data? When I try to compile this code it gives the error: "Msg 403, Level 16, State 1, Procedure UPDATE_LAT_LONG, Line 19 Invalid operator for data type. Operator equals add, type equals geometry."
create
PROCEDURE [dbo].[UPDATE_LAT_LONG]

@lat geometry,
@long geometry )

ON;
UPDATE MITIGATION_REPORTING.dbo.MR_MITIGATION
SET MR_MITIGATION_LATITUDE_LONGITUDE =

geometry)+' '+cast(@long

WHERE MR_MITIGATION_PK = @PK;
END

With this I get the error "Multi-part identifier 'DMS_MainCategories.allowPublicSearch' could not be bound". But if I put the line straight to the first string, like below, it works.
