Require Each User To Have A Unique Id - Adding New Users ?
Aug 15, 2011
For my user system, I require each user to have a unique id. The reading in and saving of the user data is all done, but now I'm focusing on adding new users. In my add user dialog, I have the information fields required to create a new user, one of which is the ID (which must be unique). For this I have created a function that I thought would always give a unique id but it does not. paste the code below:
Function getnextuserid()
Dim id As String
Dim unique As Boolean
[CODE]...

My query returns 4 columns. One column is a unique identifier for the record. I'm trying to hide that column so the user doesn't see it. I'm going to add an edit button and hopefully I'll be able to allow the user to click on the record's edit button and edit only one of the remaining 3 columns and I expect I'll need that hidden value to do the update. I've got code below but it doesn't work. It gives me an exception, "Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index ".
Dim MySqlCommand As New SqlCommand
MySqlCommand.Connection = MySqlConnection
MySqlCommand.CommandText = "SELECT ..................."
MySqlConnection.Open()
GridView1.DataSource = MySqlCommand.ExecuteReader

I'm adding labels at runtime to my form with a tag. Let's say I have 3 labels with the tags, "1", "2" and "3". I'm adding the tags by counting the labels + 1. When I remove a label with tag "2" from the form there are only 2 left. When I add a new label it will add a new tag "3", but that one already exist. So my "solution" isn't a very good one Although tag "2" is free, I want to give it "4". Any thoughts on how to code this properly?

how I can deploy my .NET applicationwithout the user having to install the program.i.e. In VB6, I could just create a executable file which did not require the user to install anything, they would simple run the program.

I made a little program for Hobby-use, and I like it to be installed by an installer. There's an installer program (Windows Installer 3.1?) deliverd with Visual Studio 2008 but that does not do the job completely. I want a coupling to be made between a program and a the users startup directory.If Windows Installer 3.1 can do that after all, can somebody explain how? If not, is there a free or low cost, simple to use (no scripting) installer program what will do the job? At last: Is there a version of .NET Framework 3.5 that does not require downloading during the user's setup procedure?

I'm just getting started with Visual Studio (2005), and my aim is to write a fairly simple application in Visual Basic that will need to store some data to disk.What I really want is to be able to send the application to the end users (xp, vista, win7) and have them just be able to use it without having down download all kinds of extras. For example I'm guessing that if I use an SQL database in my application they will need to download SQl server express or some other sql downloadable?
If so is there a similar downloadable for MS Access?I'm just in the 'seeing how things work' stage at the moment and I don't want to waste time going down the SQL track just to find it won't actually work unless my users all download SQL to their machines (which they won't want to do).

I have a basic IDE for a user control i am building. It allows me to add labels to a panel and move them around, like a very basic form designer. When I add the controls to the panel at runtime, I'd like to give the control a unique name string like how the VS IDE tracks the controls it already has and adds an extra number when it creates the default control name. I have tried checking the controls collection each time a new control is added, but wasnt sure if there was a good string comparison method to return a name with a unique number on the end that hasn't been used yet.

Possible Duplicate: Retrieve identity value from inserted record's primary key.I have a field with a unique field (that I don't have to update automatically) called ID. I'm using this code to add a field to it:
DB.Snippets.AddSnippetsRow(10, 0, Leaves, Coins, Date.Now, Language, Username, Description)
What I need to be able to do is get the unique field it adds. It +1's to ID every time I add a field there, but how do I get that without hacky database looping?

I'm writing an application that will add users to Active Directory. I'm trying to use this code to connect to the "Users" shared folder in AD
[URL]
However it adds the user in with the shared folders, instead of within the "Users" shared folder. Shouldn't CN=Users mean it will add it to the "Users" folder?

I am currently creating a windows form app with a database.The database hosts links that the user can customize.When I go to publish the file, if user A changes the Link to their liking user B also see's the changes and will cause a clash if user B does not need the link that user A has put it.
I wish to be able to have a unique database for each individual and for the life of me cannot figure out how.Currently I am having the person upload to an access DB. This is not required but I am lost for ideas

look at this picture of my index form. It's resized, now you can't see the full labels text.
Example: under the first cover, there stands "Hardbass Chapter" and accetly it is "Hardbass Chapter
21 (2011)". It's not a problem that a peace cut off, but, I want to make that clear to the users,
with adding some points.

I am using VB .Net to access the eBay API and store all completed orders in a database. This database is then fed into a proprietary shipping system, which can not handle an order number larger than 20 characters. eBay returns an order number like so 230407279314-680141236013 which is too long. The order number is always 12 numbers a hyphen and 12 more numbers. What I need to do, is turn this (the result can be alpha numerical) into a shorter, unique order key to store in my database alongside the true orderId (so that this can be referenced by the shipping software instead of the actual order number). The reason for the 20 character limit is the barcode algorithm used. Is there any way to achieve this in VB .Net 2010? This number can be anything unique, so long as it does not exist already (even a good uniqueid function would work, but I would have to query the database to make sure it isn't taken)

Using the Asp.net Membership & Profile Providers: Am I able to retrieve a user profile using their Membership UserID instead of their Username?The reason I ask is because if I have the UserID and not the Username I would have to write the following two lines of code [code]Dim Profile As Profile = Profile.GetProfile("UserID")Will this affect performance? Is my design bad? Am I missing something? I am aware that I can retrieve the current logged in user using the following code: HttpContext.Current.User.Identity.Name

I've got a website and we just had a huge jump in traffic. Now all of the sudden we're getting sql parameter errors left and right. We switched to a new sql server a few weeks ago and everything has been fine but the added traffic seems to be breaking us.I have a data access class that is called when each user trys to logon. It runs through several tasks before finally updating the users last login date and forwarding them to the administration section.
What I'm seeing from the trace logs suggests that when I'm logging in the first several tasks are using my data (lets say user=birk pass=word). But at some point the accessor class starts sending over the data from someone else who's trying to login (lets say user=abcxyz).Every connection we make to the server is closed when we're finished with it. I'm nulling out all of the accessor objects when I'm finished with them. But somehow different user data from different sessions are making their way into other peoples instances of the object.
I'm not using session/application/cache/viewstate to store the objects so I'm not really seeing how they could edit eachother... Its just really weird and I'm not sure how to even go about researching the problem.This is roughly the accessor class... I trimmed out some of the parts that weren't reliant to the issue

I have an asp.net web app that uses forms-based authentication, a SqlMembershipProvider (using an encrypted password format), and a SqlRoleProvider. I need to know if it's possible to administer the users (create new users, assign them to roles, etc.) from a windows application - the powers that be don't want any administrative functionality in the web app itself.Here is the membership provider definition from web.config:

1.I�d like to publish a free vb.net desktop application for the users to download and use meanwhile I�d like to collect usage information ex: user ip address, user�s registration information, used features, time spent� if the user allows the report to be sent back.
2.Also , in order for the user to be able to use the application, he�ll have to register it then, everytime, before the application loads, it gets verified online that it was registered, maybe validate the registration information or a valid user name and password, no critical personal information. The target of this step is for the application to be used exclusively by the registered user and maybe on his computer only.
