VS 2010 - Update DataSet To Reflect Changes In Database?
Apr 4, 2012
I 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?

I've made a dataset using the dataset designer, and I'm trying to add a column to reflect changes made to the database (added a column, nothing fancy). Is there a way to 'refresh' the dataset schema from the datasource without deleting my adapter (and all the methods and queries I've created)?

I'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 sql database, and have created a dataset for a sample table in it.The dataset is HotelDataSet2 and data table adapter to insert to it is Various_itemsTableAdapter.
MsgBox(HotelDataSet2.various_items.Rows.Count)
Various_itemsTableAdapter.Insert(Item_nameTextBox.Text, itemcode, PackingTextBox.Text, UomTextBox.Text, PriceTextBox.Text, RemarksTextBox.Text, TaxTextBox.Text, StatusCheckBox.Checked, Rate_inclusiveCheckBox.Checked)
MsgBox(HotelDataSet2.various_items.Rows.Count)
This always reflects the same count, before and after inserting..But if i execute this
[Code]...
it shows the new count to be +1 of the old one. So i concluded that everytime i change some data to the table via table adapter, i have to always refill the dataset?? How is that useful then??

For some reason my tab pages won't update their data when I change the data contained in them. I have to scroll to the next Company and then scroll back for the changes to be reflected in that particular tab. I have no clue why this is as when I walk through my code in debugging, it shows that the appropriate labels are being set the appropriate values. But if I have one of the tabs as the one in focus when I change my company, it is updated correctly.

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 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 in a situation where I have a tool which is always running. Now if any new entry is added or deleted from the database then unless we dont restart the application it will not reflect the changes. So I want that the application itself should check for the updates or at least it should refresh itself.

I am trying to rewrite a program written in an older version of VB. The old program has a input table that looks like the one below.
1) How to I get the row headers to reflect the row line number? I have tried DataGridView1.rows(1).HeaderCell.Value = "2" but that didn't work.
2) How do I make one (or more) of the cells into buttons? Each of the cells marked "Change" and "View" are buttons.

I have linked VB to my sql server and all my tables and data load correctly in VB.I drag and dropped my table in "detail" view and then debugged the program, little did I know, when I tried to add a new instance of data into my table I literally have to enter the primary key. I am trying to figure out how to set the "STU_ID" (PrimaryKey) to auto-increment off of the last row of data on my table.

I am in a bit of a sticky situation. I am currently writing a program where users are going to have to search for a specific skill in order for a calculation to take place.I have to hard-code around 500 skills but they also have to be able to search for the skill via a text box.I am stuck on whether or not to use an XML file to hold all this data or use a DataSet.I have no experience with either, but the XML file seems more appealing because I wouldn't then have to re-release the program for an update on skills, only the XML file would need to be replaced.

Ok, 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"

How can I update local dataset with mysql database without making duplicates. Assuming I set some column in mysql as primary key, which has unique string.
adapter.fill will just add duplicates, but adapter.clear before that is not an option.
So I want to update if the key column is the same with mysql data and if there is option for ignore adding new row.

Well I'm using VS2010 and I'm still fairly new at it, and with the databases in it. So here's what I'm trying to accomplish, and it too is also very basic I'm sure, but I haven't been able to figure out the few lines I need to accomplish it.
I have a generically database (Database1) and the generically names dataset (Database1DataSet) along with a table names Ruler_Information (tableadapter and bindings for this table). I have two text boxes named Ruler_NameTextbox and Ruler_PasswordTextBox. I want the database to accept these two textboxes as inputs for a new row. Here is my code, it obviously doesn't accomplish what I want, that's why I'm here:
