I have a project which contains a large number of lookup tables, and I have all of these lookup tables represented in a single typed DataSet, which contains TableAdapters for each lookup. I've designed an editor for these lookup tables, which should allow editing of one of these at a time. My front-end is written in VB and WinForms, the back-end is a SOAP web service; I can successfully pass the changes to the DataSet back to the web service, but can't find a way to use a TableAdapter to update the single table that has been changed.
What I'm trying to do is instantiate the appropriate TableAdapter for the updated DataTable by sending the name of the table back to the web service along with the DataSet, then referring to the TableAdapter with a dynamic name. The normal way to instantiate a TableAdapter is this:
Dim ta As New dsLookupsTableAdapters.tlkpMyTableTableAdapter
What I'd like to do is this, but of course it doesn't work:
strTableName = "tlkpMyTable"
Dim ta As New dsLookupsTableAdapters(strTableName & "TableAdapter")
Is there any way to achieve this, or am I taking the wrong approach altogether? My other alternative is to write separate code for each table, which I'd prefer to avoid!
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.

View 1 RepliesI fill table data into dataset using Adapter. How to update dataset changes back to Microsoft SQL Server Table. I refer to the following URL, the solution is working fine, it makes use of the adapter.UPDATE to get table updated with changes made to dataset. [URL]
Sample Code:
cmdBuilder = New SqlCommandBuilder(adapter)
changes = ds.GetChanges()
If changes IsNot Nothing Then
adapter.Update(changes)
End If
I would like to know is there any other alternatives besides the one I have mentioned above. Can the alternative supports scenarios such as update existing record (probably based on primary key or defined conditions), insert new record as well delete existing record.

I was wondering if the following is possible. In a particular operation I want to create a dataset, bulk copy it to another SQL Server, then update a flag column in the copied rows.I'll have a system that will be regularly inserting new rows of data, then at regular intervals want to copy that data to another SQL Server. Once the rows have copied I need to change a flag column so that they won't get copied again.Whilst this is going on there is a strong possibility new rows of data will be being inserted into the source table. These new rows will be copied at another interval.
View 3 RepliesI have a gridview loaded with data from my database and a gridview swapping function which after exchanging data between rows with a column call "Priority", I want to save these changes back to my database. Only the "Priority" column value will be change, how do I update only that Column of my dataset table to my SQL database?

I have written some functions that I have in a module. In one of the functions I would like to update a table that is in a dataset. I would like to do this with this function and not from a form class where the table could be bound. I need to call the function from various places in the application.

View 1 RepliesI 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?
How can i do a workaround for this? I two databases(.sdf). Database A has table A1 Database B has table A2 Table A1 is an exact duplicate of A2 minus 3 columns My dataset(.xsd) is based off of tableA2 in Database B. I can fill all my tableadapters in Database A and all info in table A1 using the dataset. My problem lies when I do TableAdapter.Update() for Table A1(Since the dataset has the 3 missing fields) it tries to update table A1 with info that isn't there and I get an error. How can I update table A1 and ignore the 3 missing columns using the single dataset? Or is TableAdapter.Update() designed to Update the Database with all columns found in the dataset ?

View 8 RepliesI'm confused about DataSources and DataSets.I created a DataSource (DataSet?) via the DataSource wizard called PPIDataSet. This has tables in it Customer, Vendor, Orders, etc.Now I want to access the data in these tables via code. So I'm expecting to be able to do PPIDataSet.Customer.AddRow or something like that. However, when I access the PPIDataSet object, in IntelliSense,I only get PPIDataSet.CustomerDataTable PPIDataSet.CustomerRow
How do I access the table data via the DataSet? Or do I have to access it some other way?
In my VB.Net desktop application, I have several places where I am accessing a table, both for reading and for updating. For example:
Dim tempCount As Integer = Glbl.GlobalDataSet.Tables("Profiles").Rows.Count
The above does not work. However, the following does:
Dim tempCount As Integer = Glbl.GlobalDataSet.Tables(4).Rows.Count
I am pretty sure it was working in th past (I have recently switched to VS 2010 - could this have anything to do with it?) but it is not working now.
How can I make the first statement work, so can access tables by table name instead of by index?
I think this may be a usual issue but I am not able to find much info. There is a master customer database and a call log database at work. The call log database has two tables that are updated from the master database monthly. Now I am writing this vb frontend for the call log database and cannot figure out the update portion
For p = 0 To maxrowsC (currently around 1000 rows)
With myCommand.Parameters

I have a Windows Form application with a form that has an underlying data set. When the users click a particular button, the code clears some fields on the form but also is suppose to update a value in the underlying dataset on a field that is NOT displayed on the form.
In VB6 and VBA this is very easy to do. I simply says Forms!formname!NameOfUnderlyingFieldNotshown and pass it the value. How do I do this in VB.net with a Windows Form and underlying dataset?
I have 2 databases that I am working with. One is a compant customer database and the other is my personal call log. Now I am creating a front end for the Call Log. I was updating my customer list by Importing 2 tables from the customer database, a series of queries would erase all of my info, take all the data from the imported tables and move it into mine then erase the imported tables.
Im trying to accomplish the same in my VB frontend. I can connect and fill datasets from the customer database. I can erase my tables. How do I take all of this data from the newly created dataset and move it over to my empty tables?

I've created a Point of Sale program using Access and VB.net. I have an Inventory table from which items are sold. There is a quantity column and I want to be able to reduce the quantity for any item by the quantity that was sold in the point of sale front end. For example, there are 5 bracelets in inventory and 1 is sold. The quantity is typed into a textbox. The inventory quantity should now be 4 in Access. I don't know how to make this happen from the point of sale screen.

I use a dbDataAdapter to populate a DataTable from an unlinked oracle database.I have a dbDataAdapter that I want to insert rows into an SQL Server table using SQLCommandBuilder.I have been trying all day to update the DataTable that references the SQL Server table with the data from the Oracle DataTable so that I can insert the rows.
View 2 RepliesI've create a new VS 2008 Window Form Project using VB. I added an oleDbDataAdapter to the first and only form, set it to a table in my Access 2007 Database (there is only one table, PK field autonum of course and two Memo fields). The Database is in the Project's folder. A standard oleDb Connection object was created, as I expected, then I select the DataAdapter and choose 'Generate Dataset' which produces a standard DataSet called 'DataSet1.xsd'. Now when I build the project I get an error 'Error 1 Type 'FontTest.DataSet1' is not defined.' I do have a reference in my new Project to System.Data.So what the @#%$@ is going on? Why isn't the Dataset create by the DataAdapter being recongized? I can get into the DataSet Designer. The DataTable create is perfect, three columns defined correctly as I expected.
View 2 RepliesI have looked all over for a solution to this problem and have tried a bunch of different things, but nothing seems to work.I have a sub procedure that does the following:
1) adds two columns to a data table (table1)
2) fills a dataset with several tables in order to make calculations (this determines the data that will be stored in the two new columns of table1)
3) updates ONLY table1, and ONLY the two columns that have just been added (these columns are thus empty for every row before the update begins)
As it is now, the da.Update takes about 3 hours to populate the entire table (it updates about 300 records per MINUTE if I'm lucky). There are approximately 40000 records in table1 for this test subset, but there will eventually be up to 1.5-2 million (in other words, this is a small table currently). I have tried using executenonquery() along with a sql UPDATE command instead of da.Update, as well as many other things, but none of them has improved performance at all. I've also tested it on two PCs, one running Vista and one XP, and there were no differences. I'm using Access 2003. I know Access is not ideal, but for now it is the only option.
I know that the root of this is the line of code with the da.Update, because the giant loop before it that I previously thought was causing the slowdown executes in 30 seconds, leaving only the update before the subroutine is complete. I don't know how exactly the da.Update works, but I've suspected that maybe it has something to do with that? Code is below:
