So I'm not familiar with much vb code but I was hoping someone my spell out something pretty generic as far as updating a database. I'm pretty sure I've successfully edited rows but when i'm using my database update i get an error, probably just incorrect syntax. This is what I have so far...
[Code]...
I use this code and update the database with changes in my DataSet but the changes are not showing up in the database.
' Update the connection object.
'------------------------------
myConnection.ConnectionString = FormMain.strDatabaseConnection
[code]....
I have a form in vb8 that is set up as follows:
I have a table in my Access database calledUsers that has a name and a password (encrypted).
Using the toolbar I created aBindingSource with a name of UsersBindingSource and a dataSource ofUsers
Using the toolbar I created aDataset called with a Name and a DatasetName called Users_Dataset
Using the toolbar I created atableAdapter called UsersTableAdapter
I added two textboxes on the form and changed theirDatabindings...Text property to the corresponding field in the Database.
How to now update the database when I click Update. What the program needs to do first is encrypt the Password before saving it. I wrote the code in the TextBox2.Lostfocus event to encrypt the data a place it back into the TestBox2 field. The only samples I find on the net refer to DataGridView controls (which work) but I don't want to use them. How can I get the database to accept these changes as well as changes to radio buttons or comboboxes?
On a form i have several text boxes binded to a bindingsource and including a datagridviewI have populated the textboxes with database fields successfully and the datagridview displays the correct information.I have the following code to save the information to the database but i cannot get it to work. [code] I have tried many code examples here in order to save the data, none of which has worked.Can anyone please help me with this?

View 1 RepliesI am developing an application which uses a database that holds the information about a company and it's personnel. but when I try to edit already existing data in the dataset it just won't update it. I've tried all the method the MS sites provided me, but it just won't. the code looks like this: (notice this code wasn't complete)

I am popolating a DataGridView with a DataSet from an SQL database like in example bellow.
After I am making some changes I need to know how can I save modified data in SQL database>
Let's say that I have a form with a DGV and a button. On load I will put ten lines from a tbale from database inside the DGV. Then i will make some changes and after that when I click on the button I need to save the modified information. Everything has to be done on runtime.

I am using vb2008 express edition and SQL Server 2000What I am trying to do is programmically populate a dataset with records from a database and then bind the fields to textbox controls so that and changes will be updated in the dataset and eventually the database.I have managed to get as far as displaying the data in a form, but cannot understand how to update the database when a button is clicked.
View 3 RepliesI am currently developing an application that is linked to a MS SQL Server 2008 Database. So now I realised that I needed to make a few minor changes to the database (add new columns to some tables, change the data type of a few columsn in some tables). After making the changes, I realised that these changes have not been updated in my VB application's dataset. I then tried to "refresh" the dataset, but it still is not updating the dataset. What do I need to do to update the dataset to reflect the changes in the database?
View 1 RepliesI'm developing an application where depending on a textfile input i should update/insert some data into an Access database. Let;s say I'm updating the bookshelf of a book according to a textfile that goes like:
TEXTBOOK | BOOKSHELF
000000001 | 000000000A
and so on
[Code]....
does that make any sense? What I'm trying to do is basicalle: check if a book exists, if yes, then attach to Dataset, change its Bookshelf to the one in the textfile and repeat until the file is completely read. The Bookshelf can or not exists, if it doesn't then it should be inserted, is it done automatically when I update the Dataset? Finally "Batch update" the whole Dataset.
i have a dataset that filled by this query :
SELECT Invoices.ID, Invoices.invoicenu, Invoices.pdate, InvoiceList.icaption, Invoices.icaptioncode, Invoices.ccode, Invoices.postedbill, Invoices.billnumber, SUM(InvoicesDetaile.price)
AS Tprice
FROM InvoiceList INNER JOIN
[code]....
a datagridview is showing dataset data and user check checkedcolumn of datagridview (postedbill filed) and after user mark a few rows , i want update (invoice table) in database .
I am connecting to a web service that returns a dataset that I use as a datasource for a windows client datagridview.
Once a user has made changes to the datagridview record(s), how do I get those changes back to the connected dataset and back to the remote database.
I wrote the sql update function in the service:
Code Snippet from web service
<WebMethod()> _
Public Sub Update_equipment_repair(ByVal repair_id As Int64, ByVal date_entered As DateTime, ByVal date_sent_in As DateTime, ByVal date_returned As DateTime, ByVal damage_description As String, ByVal vendor_id As Int64, ByVal repair_description As String)
[Code]....
This displays the records perfectly and I figured out how to delete and insert records via web service.
writing updates from the datagridview back to the database.
I am writing a small windows client application that accesses data using a web service that returns datasets.When the dataset is returned, a datagridview's datasource is set to the dataset.
My question is, how do I write changes that were made in the datagridview back to the dataset and then back to the remote database.
[Code]...
Now the client snippet that connects to the service and lists the equipment

View 1 RepliesI have a dataset (WW1Dataset) with one data table(WW1).(database used in an access database) I'm trying to filter the dataset e.g a user wants to filter by a chosen surname (SurnameTextBox.text) so the datset is filtered to display only those records wherethe surname column in the dataset matches SurnameTextBox.text.
View 1 RepliesOk, so I have created an Access database, and everything is working fine (much to my amazement) except for one thing. I want the database "update" button to validate the input before applying it to the dataset, and if there is an error (empty field) I want it to pop a message and highlight the text box in question where the error occured (there are 7 textboxes).
How precisely do I go about doing that?
CODE:
This is what I have so far for the update button. I attempted the "textbox1.isnullorempty"
