When Update The Dataset The Focus Comes On PhoneText_Leave
Feb 6, 2010
From my main application, I call CustomerDetails form. User confirms data and makes changes if required for which again a call is made from main applicaiton file only. This time am making some changes in db and on calling adapter.update(dataset), the control is gone to a textbox leave event of CustomerDetails form. The code is :
In main program :
' Open Customer Details to Show the details, once confirm, show Order form
cd = New CustomerDetails("VW")
[CODE]...
My concern is when res = 3 i.e. Modify. What I want is, I remove all data related to that customer via DeleteOrdersOfCustomer() & then allow user to update the details. But here, in DeleteOrdersOfCustomer, when I update the dataset, the focus comes on phoneTxt_Leave. I don't want to go the focus anywhere unless I complete the DeleteOrdersOfCustomer() How can that be achived or else I have to add cd.close & cd = nothing before calling DeleteOrdersOfCustomer().

Today i have been checking out the concept of datasets and i like the way they work except for a minor issue i have with it.The following code should get a databasetable and put it in a dataset and return that set to the user.[code]I submit the table name and it will select it, read it and fill the dataset with it, then return it. And it does exactly that once.If i try to re-read the same datatable it just returns the exact same dataset as the first time yet i am 100000% sure that i changed it .

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...

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?

I have a datagridview that was bound using the wizard and all the column created that way. So I haven't done any code to bind the datagridview. It will pull the data from the database and dataset just fine. My problem is when I create a new row it won't update the dataset or database. I have tried different ways that I thought it would work in the code and still haven't found a usable way to do it yet. Or if I need to do all my binding and columns through code give me an idea where to start if I have to go that route. This is my first experiences with Datagridview. I normally use comboboxes and textboxes to write to a dataset and database which all work very well.

I have a vb.net form with a dataGridView
The dataGridView data source is the dgvTableAdapter with this sql statement
SELECT membres.ID, membres.refere_par, bands.titre,
membres_1.prenom & ' ' & membres_1.nom AS reference_nom
FROM ((bands INNER JOIN membres ON bands.ID = membres.[band])
INNER JOIN membres membres_1 ON membres.refere_par = membres_1.ID)
[Code]....
I know the delete statement works because I saw the changes in the database. If I close the form and reopen it, the dataGridView is up to date.
The membres table is an access table
I'm running the app in visual 2010 debug mode.
