Update A Database Row With The Update Command?
Feb 11, 2010is there a way to update a database row with the update command by first defining all parameters and then all values just like you can in the insert command? "insert into table1 (parameter1,parameter2,....) values (value1, value2,....)"something like "set table1 (parameter1, parameter2) values (value1,value 2,...) where ...."?because I only know the syntax to define each parameters value "set table parameter1=value, parameter2=value2... where"

Jul 8, 2011Ill start this by saying im still very new to VB, ive had some programming expereice here and there since high school, but never really did much with it till now.Ive got a small app that im working on for a side project, i want to add the details of a given days records from a simple POS system i have built up so far. At this point i have all of the information generated and i cant seem to get the app to commit it to the database. I have seen tons of posts on this, and i have followed a bunch of them to no avail. Im sure this problem is because i have the code written wrong, and i cant get it figured out. Here is the code that im using to try to save the data:

Update Database Using SQL Through VB?
Jun 12, 2011I'm currently working on my A2 computing project, and I am having slight difficulties updating and saving the data in my database when it is entered on a form in VB. I cannot find any reason why it wouldn't work, but if someone could suggest a better way to do it, it would be great as everything else works. It's in the btnsave at the bottom, and when you click the button on the form it come up with a very unuseful error, which is no help to anyone.
This is the code for the edit details form, where on loading, the customers details which are currently in the database are already there, and they can change things on it and save it to update their details if anything changes.

Best Approach To Update A Database?
Jul 18, 2009I am writing a program to assist Paramedic students in learning the Drugs that they have to know in order to pass their classes. I have created an Access database to hold all the information on these drugs, but not every student that will use this program will need to learn all the drugs contained within this database.
Right now I have 43 drugs in the database and still growing.
What I want to do is to present to the student the drugs and have them say "Y" or "N" as to whether its on their required list to learn. That way they only work on the ones that they need to.

Cannot Update The Database Because Is Readonly?
Jan 24, 2011I had created a simple program that uses a MDF file as Database, this includes in the project 2 files: mgcdb.mdf and mgcdb_log.ldf, the program installs in C:Program Files(x86)CompanyNameProgramName, then when I try to update the database I get an error "Failed to update database because is read-only".
During testing on VB I had no problems, since the database was being use by "Authenticated Users group", but on Deployment the Users group don't have enough access to work with these files. So far I know or at least I think that what I need to do is to ADD access to the user, right? Since I didn't know how to do this I found this address [URL].. where it shows you an example on how to add/remove access to a file. I changed the module to this:

View 2 RepliesDatagridview Changes Do Not Update To Database
Mar 31, 2012I have an application doing the following:
- Treeview with customers
- on clicking a treeview, for every project of this customer, a new MDIchild opens, where the products of this project are displayed
- the MDIchild is basically a DataGridView, which is connected to the products-table via a DataView
my Problem comes after changing a value in the products DataGridView:
- if i do not change the row, the changes will not go back to the database after an update
- if i do change the row after entering a new value, everything works fine
The strange thing is, that in both cases, the value in the DataTable is changed, the DataSet is "hasChanges=True" and the DataRow's state is "Modified".

View 2 RepliesEvent To Use To Update The Database ADO.NET?
Mar 1, 2012I'm getting frustrated on how hard it is to find a good DataGridView event, BindingSource event, or DataTable event to use to update my database. I have to use a stored procedure to do my adapters update, because when a user updates a row
I have to check for concurrency to ensure 3 other related rows to the row that has been modified hasn't been updated since the user obtained the data. For example, if my query returns 4 records and the user updates the 4th row, I have to ensure rows 1-4 haven't been updated since the user retrieved the records.
My DataSource is a DataTable and I use a BindingSource to bind it to a DataGridView. I want to update my database whenever a user changes a cell value in the DataGridView or when I change a value programmatically to the underlying DataTable. Anyone recommend an event from any of these objects?
The problem I'm having is this. When the user changes a cell in the DataGridView I want to apply a date time stamp in another cell in that same row before I update my database. If the update is successful for that row then I AcceptChanges or if it fails then I RejectChanges for that row. I can't change any values in the row in the DataTable RowChanged event because it will be an endless loop, plus it does fire when the user changes a cell. I can't use DataGridView CellEndEdit because when I change a cell value programmatically using a loop the event won't fire to do the update. I can't use DataTable ColumnChanged event because the row hasn't been set Modified so the adapter doesn't know to update the row.
What do the experts recommend?
