I am very confused about the database type to be used in my vb.net application. I have been using SSCE database, but for that user has to download and install SSCE, which many of my users do not want. If I use Access, the security issue is very very serious.I have downloaded a few database apps from the internet, which donot require any such thing to be installed and also I see no known database format in the application folder. I wonder what kind of techniques they are using.

My Form 1 has a drop down list for user to select username, followed by a textbox to enter password. If correct password is entered, Form 2 will show.
Form 2 start from cbxCategory for category, then another cbxItem for item. Then a button to click �Borrow� Then it should insert.
This is my form 2_load codes:
Private Sub Form2_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Form1.Hide()
[Code]....
I keep getting an error when I try to insert the record. What's wrong with my code?

I have a form that contains a Textbox + Three sets of radiobuttons.
my project idea is to store in any database the values selected or entered by the user.
Textbox goes Name.
First set of radiobuttons are the job position - manager - superviser etc....
Second set "" "" the Period (Shift)- day - nite
Third set "" "" The Condition - part-time - full-time
Anyway, my problem is how to insert those values into a database, something very simple such as MSAccess (is possible?)

My problem is fairly simple. What my code is doing to start with is opening the form by loading a bunch of things from a database. After all the questions are done (because it is a questionnaire) it is meant to save the current score and the username that was entered before, for the sake of programming I have hard-coded a username and score however I think because I am using a different command builder it keeps giving me the same error!
(I am studying A-Level so that might explain the simplicity of the code)

I was wondering how to get a certain data from a MS database and display in a label. Example(Database entries)
[Code]....
The name will be displayed in the label depending on the year and number typed in two text boxes. So if typed 2009 and 1001, the label should display name2. I don't have any background on SQL. The only thing I did for now is that I added the database in the data sources and added a TableAdapter.

Write code or use tableadaptors, bindingsources, dataset, etc.? I have experience with the older ways i.e. connection strings, ado code, sql, etc. but was hoping the newer tools in vs would make the user interface easier and more flexible. So far i have been disappointed. Am I wrong and I am missing something? Am I alone in this opinion or ? What is your past experience in VB and have you found vb.net to be a step forward in db user interface design? if your answer is yes then what is the easiest way to put a table record count into a text box? should i bypass all the new stuff/objects ( adaptors, binding sources, navigators, designers, etc) and just write code or what?

I am trying to delete rows of an .sdf file using the Database Explorer utility of Visual Basic. When doing so, I get the following error message:No rows were deleted.
A problem occurred attempting to delete row 1.
Error Source: Microsoft.VisualStudio.DataTools. Error Message: The row value(s) updated or deleted either do not make the row unique or they alter multiple rows(48 rows). Correct the errors and attempt to delete the row again or press ESC to cancel the change(s). It is correct that the data in the rows are not unique (and not supposed to be; there is no "error" to correct), but why should this prevent deleting them?

i seem to have a problem when i try to update a certain record in an Access 2007 Database. I have a small Access 2007 database with 1 table which has 3 Columns and several records. The 3 columns are RecordNumber (Primary Key and it is autonumber), FirstName(text) and LastName(text). What i am trying to do in VB 2008 is implement a search form which when you find a record you can update it. I do not have any problems with the search, but i cannot seem to edit any other record than the first one. For example i search for John which exists, if that record is the 3rd record when i try to edit it whatever changes i make (for example change that to James), the changes i make are made to the first record and not the current one. I tried a lot of things but nothing works, here is my code:
