However, my insertcommand is shown as invalid. so I need your help to figure out my errors. I put the codes in my reply below to be clear.
I'm trying to create a simple Data Grid that will automatically save changes. So far I have a data grid connected to a MS Access 2007 Database that reads the data. I can create new fields in the Data Grid, but I need to program to save the data automatically to the database on update (or on close).
I have a database, added in data sources. I can manage records with automatically generated database toolbar.I want buttons for Add, Replace, Erase data from Database. So far i've seen some Tutorials but they are most likely for VB6 and also i'm really new on VB at all.

Only my local dataset updates when adding, deleting or editing records.The Source Database is supposed to update on issuing DataAdapter. Update(dataset )However, when I check my source database after running the operations it remains the same as the original.
I don't know if I can have several same forms to do the manager jobs, ACTUALLY THE STORE VALUES ARE DIFFERENT(those forms can have the independant data values to store into the forms), like if I can have the datagridviews to store the different values? SO,MY QUESTION IS if I can have several same forms(FROM ONE SAME FORM), and can store different data values into the forms with vb.net & access, OR I HAVE TO CREATE SEVERAL SAME FORMS.

If you have to store and retrieve data from a database is a string not the most effcient way? What is best?
How does this work in a real world scenario.
For example: I have a customer ie first name and last name and the CustomerID is autoincremented when initially added to the database. Now, the user could lookup and find the customer by their ID but we all know that's not practical. They don't know 231223 is John Adams, they know John Adams or Adams John.
So how do you handle this? Access is the database I am using but I think this would apply to any database.
I am following some examples I have found in earlier discussions, but have run into a problem trying to save the data. I have included my code below, and everytime I reach the ExecuteNonQuery() command it generates a syntax error in the Insert command error.[code]...
I am new here and really excited to see the huge resources on this forum for vb.net. I have just started my learning of vb8 and need to create some basic applications for my personal use.I need to develop an application that can extract data from a html table and store that data into Access database. I have learned to create web browser on Visual Studio 2008. Below is the link from which I need to extract data and store into a database
I have written lots of code with the ADO Library in VB Excel and previous versions of Visual Basic. With the dissappearance of the recordset object, how do we perform data manipulation with an attached Access Database? It seems things could be a lot easier, and less complicated by now, however, the best methods appear to currently remain ellusive.

I need a way to store just the time only to my access database. the datetimepicker isn't working because there is no way to have a null date.I found this and it seems to be exactly what I need.When I try to convert it to vb2008 i get a few errors I can't figure out.
I'm trying to retrieve data from an Access database - a simple one. (Just a single table with one column) My task is to view these records through a 'ListView'. No need to manipulate or anything. Just to retrieve data with a simple SQL statement and display via a ListView.
A simple database has been created in Access, which is just basically a table of text, with some images as entries. A form has been created in VB2008 Express and linked to the database. Either a combibox, text boxes or pictureboxes are linked to a column form the database. The first row entries are all displayed correctly in the relavant boxes (except for the images, which for some reason aren't displayed). If another value in the comibox is selected, the other box values don't change and there is still no images visible...
I'm creating an application and I want to pass on a string value from one form to the other.Is there an access modifier in VB 2008 EE that would allow me to do that?Example: I have a name such as Mike in one form, in a list box, and Mike has a file attached to it with different information.I then click on a button to load another form, where the name Mike will be passed on and will be used by my program to find the file and display all the information in the file of his name.
concantenate rows from my ms access database using vb.net. I have a table in ms access where there are contacts of clients, so now i want to seleect only mobile numbers of all clients and then concantenate them seperated by deliminated commas. give me all the mobile numbers into a single row/line seperated each number with a deliminated comma. I have tried different methode but it gives my endless errors. Amongst other things i tried to bind the mobile numbers in to a listbox so that i can loop through and insert all the number in the textbox seperating them with a deliminated commas....that does not work it says "Operator '+' is not defined for type 'DataRowView' and string ";".
This is the code i have used:
Dim address As String ' Dim n As Integer For i As Integer = 1 To Mobile_PhoneListBox.Items.Count - 1 Step 1
I am working on my new project and I need to create a table for each user dynamically. In which the user will provide the Table name in the textbox and on pressing Create button a new table gets created in the same MS access database file with the provided name.[code]...
i have successfully connected VB2007 Express edition to MS Access 2007 but i don't know save the newly entered record into access database from the VB interface.
for an example I'm making an RPG game for learning purposes and I have several modules, each for storing different data (one for items, one for enemies etc).I'm storing each item or enemy in a structure in the module so it's easy to find and obtain the values and makes it easier to add more when needed. I'm sure there's a easier way because at the moment I'm storing it like this:

As you can see, I have all the weapons(which are in a structure) nested into another structure called "weapons" so it's easier to find.Is there an easier way to store the data and make it still readable, obtainable and easy to add more weapons later on.To display the stats on the currently selected weapon I have to test for which weapon is selected and then several lines of code just to display the stats for that one weapon.
Microsoft Access 2007 A Students.mdb database file Visual Basic 2008 Express Edition. I was informed that one can connect to Access files with ease from the Express Edition and most of the tutorials on the internet also show this however I am encountering a problem.
I open Visual Basic 2008 Express Edition Start a new project, with a form, and then click on the Data window, and add new data sources from the Data menu.
I click on database. The problem starts with the data connection. I click New Connection Change the Data Source from Microsoft SQL Server Compact 3.5 to Microsoft Access Database File and instead of then leading back to the other window (as happens on the tutorials for me to browse for the mdb file). Another window pops up asking me to Add a Connection.
It has the data source listed as Access and asks for a Connection String under the misc section. I type in
CODE:
When I click on Ok I get this error: Format of the initialization string does not conform to specification starting at index 0.
The Test connection button works and says connection success whether the Connection String field is empty or not but when I click OK it still gives me the same error. So I can't leave it blank either
So basically I can't connect to the Access database since I can't change the connection type and it won't just let me browse and add the file anyway.
