I have a trouble updating my records to SQL. I have a programme, It will save user entered records from spreadgrid to sql server using "do while, loop" method. Later it will load the saved record to the same spreadgrid for editing the records by programatically not using the inbuilt datasource method.the problem is how to update the old records with the newly added records programatically especially with "do while, loop" method. I hate the data adaptor method.[code]....
I have created simple database project, using vb.net, ado.net, oledb, datatable, datagridview.My program is working nice, I just need Help with how to add, delete, update and edit records.
I am using following code to edit and update field in my databse table. But it does not cast any effect on database. Dim drCurrent As DataRow drCurrent = DbResultDataSet.tblResult.Rows(0) MsgBox(drCurrent.Item("PaperID")) drCurrent.BeginEdit() drCurrent.Item("PaperID") = "433" drCurrent.EndEdit() TblResultTableAdapter.Update(DbResultDataSet.tblResult)
i am using MsAccess as database.insert/edit/delete commands are working perfectly in my code. the problem is that if i insert a record it is definitly inserted in table in MsAccess but that cannot be seen on runtime. To see that inserted record i have to close MsAccess Table to verify that the record is inserted there. And also I have to stop debugging and then restart debug to see that the record is being displayed in Datagridview. How i can changes in records can be seen on runtime in DatagridView as well as in the MsAccess table on runtime.
I can add new/delete info to data, but cannot update/edit, I have tryd everything that I could, but no luck on my side, I have put txt file of my page.
I have a DataGridView bound to a non-SQL Server database. I need to allow users to edit existing records but under certain circumstances I need to intercept the edit and instead of committing and updating the dataset I need to delete the edited record and re-add it as a new record. I have tried using every event I can think of to do this but haven't managed to get it right.
The closest I have got is with this: Dim theRow As DataGridViewRow Private loading As Boolean = True Private rowLeft As Boolean = False Private WithEvents cm As CurrencyManager Dim copiedRow0 As String [Code] .....
This almost works but sometimes completely messes up and re-adds rows twice and all kinds of other bad side effects. It seems a really simple thing to want to do but I just can't get it working.
I'm trying to create a Library System in VB 2010 which is connected to a 2007 MS Access Database manually. I was successful to create a "Search" button where it displays content from the database based on the user's entries on several text boxes.
The result is shown on a Data Grid which I set to allow Editing on it. My problem now is I can't find a way to create an "Edit" button. My idea is basically allow the user to search, let the result be shown on the data grid, edit the data grid, and click the Edit button to save the updated records back to the database.
My question is it possible to create such button? Here is the code that I use to connect to the data base for the Search button. [CODE...]

I'm using visual basic 2008 express edition by linq to sql for my database operation such as edit records. I did not use any sql server but I'm just using the built-in sql server within the visual basic 2008 express. I tried to revised the codes, no error in syntax but there's an error at runtime and it pops-up a window message saying its error message. What I want is to edit the records which were retrieved from the database into the text-boxes and when you click the button5 whatever the new value on the text-boxes should replace the previous one.The Account field is the field in my Table1 in memrec.dbml which I set up for primary key is true and the rest of the fields are false in its primary key.[code]...

I Fill a DataTable using a SQLDataAdapter then use a BindingSource as my DataGridViews DataSource. My DataGridView contains a ComboBoxColumn named "Status". There are two ways to update the Status column. One, the user can change the value by clicking a cell in the column then the combobox appears and they make their selection. Second, the user can click a button on the form and the Status for all the visible rows are changed to "Exported". I use a stored procedure as my adapters Update command.
This is the hardest part of LinqtoSql database handling operations in visual basic 2008 I ever encountered,w/c is the update operation cause Ive been posting this thread several times from the other forum site but noone yet was able to answer my question,examples were given but its not efficient cause it won't specify based on the codes i gave and i know its not easy but im still hoping that one of the answerers of this forum will be able to resolve this particular linqtosql operation codes. I used textboxes in manipulating all data into the database such as displaying records, adding records, & updating records, basically I used with textboxes in doing those database operations. I will give you 3 block of codes w/c corresponds those database operations I used and differentiate from each other inorder for us to determine why one of them has no progress or won't do its operation w/c is the update operation...
*************Block of Codes#1(Adding Records)************* Private Sub Button1_Click(------------------) Handles Button1.Click Dim db As New memrecDataContext()
[code]....
I would like you to identify,differentiate, or troubleshoot the block of codes#3, or anyhow, why it has no progress at all or it won't edit and change the records but it runs and no error in regards with its code, and the other 2 blocks of codes were able to successfully do its operations.I was just wandering why only the block of codes#3 is not doing its operation successfully when you change the record being displayed in the textbox.Is there a possible way to edit records in the textboxes?If there is.... Is it possible to debug the block of codes#3 to successsfully do its operation? If you could possibly give an example,can you based it on the block of codes#3?
I am trying to use the combobox to update/edit/view the saved data (in contact form) from sql server.

The problem now is when I saved a record into sql server (EG Technical Manager) and try to view back the saved data, it always show the first item (Director) in combobox. But, my sql server has saved is "Technical Manager" for that saved record.
