View 5 RepliesA new project requires that we have two servers set up to accept requests. Originally we had a reporting system which queried a database and brought back various details to the user. We now obviously need to query two database on seperate servers and merge this information to provide real-time reporting.

I am building VB.NET application that takes data from text files that are exported from a legacy DOS program. These are written to a datatable and displayed in a datagridview. Right now my code simply loops through the datagridview and inserts the data into the database (SQL Server). There is a requirement now that the client number must be checked before the insert to see if it exists in the database. If it does, then the value of one field (tax rate) is checked against the value of the field in the datagridview. If there is a difference, then the rate is to be updated in the database and the data that was in the database is to be written to a history table for audit purposes. If the client number is not there, then we are to do the insert (which is already written). I want to know what is the most elegant and efficient solution for this problem.
I need to compare what is in the database table with what is in the datagridview, update the history table for records that exist, and then insert new records.
I have a DataGridView table that I allow the user to enter data into. I have a button to add a row. This works OK but how can I select that row after the button has been clicked. The reason for this is so the user will not have to scroll to the bottom of the list the enter data into the new row.

Im trying to add values stored in an array to a database. Here's a little piece of the code.
[Code]...
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 to get the value of table in sql database and adding in existing table?
View 1 RepliesI am using data grid view in Windows Form standalone application to display items as excel spread sheet in VB.NET. I got a table named CostTypes with column names [CostTypeID, CostType] and values [1,External] and [2,Internal] (These are constant but more values can be added to table).
I want to create columns with names of the values[External , Internal] in DataGridView. If I use databiding directly I get columns [CostTypeID,CostType] which is not what I am looking for.

I have a class that represents the table of a db-row. Its properties are the columns of the table. I add a new row to the table with the following code:
Public Sub AddRow(oTestRow As TestRow)
Dim sql As String
With oTestRow
[Code]....
That is just an example, but my classes have around 30-40 properties and this brings a very large and complex sql string. Creating, editing or maintaining these sql strings for many classes could generate errors. I am wondering if any compact way or method exists in order to add the whole object's istance (the properties of course) to the table "TestTable" without writing such a large sql string. I created the TestRow in the way that its properties are exactly the columns of the table "TestTable" (with the same name). But I did not found in the ADO.NET anything that could be used.
I have a datagridview which is bound to a local databse table through a Linq to SQL class.
Everything works as I would expect, when the application runs, up to a point.
If, in the datagridview tasks pane I enable Adding, Editing and Deleting all work as expected.
If I disable Adding & Deleting, leaving Editing enabled, Editing works as expected.
If I disable Deleting & Editing, but leave Adding enabled, Adding does not work, despite the row for new records being displayed. I can move around the row but not enter data.
I suspect somehow its the datasource as opposed to the datagridview that is the cause of my problem but as I say, I can add rows if the Enable Editing option is selected.
Changing the relevant properties programatically makes no difference.
I've been searching for the reason for a couple of days without success.
I have a workaround, by leaving Enable Editing set and programatically setting each row during the RowPostPaint event to be readonly except the row for new records. I would just like to understand what is going on.
I am making a application that has the ability to edit values on a access database table. As a simple example, My table looks something like this:
Order Number Completed
2000 No
2001 No
2002 No
The application needs to edit the Completed columns. I have 1 text box, and 1 button in my form. You enter the Oder Number in the textbox and press the button. The VB application then needs to change the Completed to Yes in the database. Example, I type in 2002 in the textbox and press a button. The application changes Completed to Yes for this order number in the access database and saves/updates the database.
I am unable to load the dat into the data Grid. Here is where I keep getting stuck.
dgvOleDb1 = table.Select
dgvOleDb1.DataSource = DataGridViewEditMode.EditProgrammatically
dgvOleDb1.DataSource = ds.Tables(0)
I am confused; I am using VB2010, IBM.iSeries.DB2 on an as400 V5R4. I am trying to establish an OLEDB connection, and return the values from the selected table to a DataGridView. I had one of the admin's make me file named GARBAGE, in the Rprtaccess catalog. In the past, I have been able to connect via access and an ODBC connection. My project is too big for access, and the SQL middleware we have is clunky and not user friendly. This is a program that will generate the SQL statements, specifically the WHERE: clause and populate the datagrid with the selected criteria. In essence I am making a user friendly striped down program, that has variables that are manipulated by the end user, and the rest, referenced tables and libraries are coded.

I have to compare an item value in two tables. these two tables are on different database(same server).
I have succesfully generated sql query to return both table values.

It is resulting with no rows.
Does the connection to multiple databases wont work from vb.net.
The following classes are used to get the result ...

There are 2 subs. First one populates a DataGridView with data from a SQL table:
Dim SQLCom As SqlCommand
Dim myDA As New SqlDataAdapter
Dim myDS As DataSet = New DataSet()
[Code].....
In the example from my book, I'm coding a button click event, and adding the code..."me.width=me.width + 20"The author states that "me refers to the object to which the code belongs(in this case the form)".
But this isn't exactly accurate, is it? The "code belongs" to the button object -- not the form object, right? So, I'm guessing that what the author really should have said is that "me refers to what ever form you're working on". Would that be true?
I need an application which opens a table from a database(in my project) in a Datagridview. Then it allows me to modify it and save the table. I managed to do all this but when I open the database in my project( with Ms Access) the data remains the same. Why is this happening?
I have all connections working and I am using this code to save:
Me.RegistrationTableAdapter.Update(Me.ContactsDataSet.Registration)I need a reply asap if it is not a problem.
I have one textbox at form named "Ord ID". I have bind database table with datagridview control and now on load event data is displaying correctly. In Datagridview there is one column which is checkbox type, suppose at datagrid there are 10 records displaying, and I have tick 6 checkbox for 6 records, so when I press add button then the value exist in textbox automatically comes to only six records of Datagridview column named "StatusID".
