Oct 5, 2009
I have an office project which shoudl basically do the following:
1) take different TEXT files of fixed-length fields and put them in separate tables.
2) use the data from the different tables and compile them to a master table in a mdb.
3) display data in compiled mdb in datagrid 4) allow editing in datagrid 5) save the data in datagrid into the mdb 6) save the data in datagrid in a csv file i did some googling and came up with the following code:

I've been working with a remote mysql database. The design of the database pretty much requires that I use SELECT commands that include multiple tables, and sometimes joins. Updating a single table query is SO EASY, yet dealing with multiple tables has me pulling my hair out.
[Code]...
What's killing me is that if I make a change to a field in the products table in the datagridview and press button1, the changes are saved. If I make a change to a field in the specials table in the datagridview and press button2, the changes are saved. If I combine the two updates together in a single routine, only the first one is saved. I presume this is because after the first update executes, the dataadapter no longer reports that there are any changes to save, since the update already happened.
I've tried breaking this up into separate dataadapters for each table, but then even using dataset relations, I can't get the data together in a single datagridview. On top of that, the grid itself is only intended to be used for searching and querying data. It still needs to be bound along with a set of textboxes that accept the input.
Lastly, this database is part of an ever-evolving website database with dozens of tables that need interfacing. I just can't see manually maintaining hand written sql statements for every table. That's why I've been working so hard to get the commandbuilder to handle it.

I am using ADO.NET Datasets in my VB Applications. I have a typed dataset with one Parent table and many child tables. I want to generate Identity Key when I insert data into Parent Table and then update the data in all child tables with the Same key (As Foregin key).At last, I want to update the dataset in Database(SQL Server08).Well, the above thing can be possible by first inserting Parent Table in Database directly, get the Identity column and than use to for Child tables.

I think my subject sums up what I am interested in knowing. I am looking to create a chart where Series1 is from Table1, Series2 is from Table2 in the given Dataset. My code below doesn't throw any errors, but it appears to be grabbing the data for each series from the first table.
Imports System.Windows.Forms.DataVisualization.Charting
Public Class Form1
Public Sub New(ByVal ChartData As DataSet)
' This call is required by the designer.

There is a "how do I video" on how to properly control updates, inserts and deletes in multi-user applications on forms that edit master-detail related data. [URL] Massi worked through the process using Order (OrderID is PK) as the master table and Order Detail (OrderDetaiID is PK) as a related table in dataGridView. The dataGridView automatically generate orderDetailID whenever the mouse enters in a new row. I am doing a similar form, but placing order form and orderDetail form in two separate tabs in a tabcontrol, and also using Details view for both tables. When I click "new" button in BindingNavigator, the orderID is automatically generated. If I use dataGridView for my orderDetail tab, then the orderDetailID is automatically generated when the mouse enters. This allow me to insert/update tables correctly. However I need the Details View for my orderDetail form too. How do I get a orderDetailID automatically generated when user insert a new order and have the mouse click on OrderDtail tab?

I'm an experienced Office & VBA programmer, I am new to .NET programming. I'm in the process of migrating an Access 2007 database application from Access to Visual Studio Visual Basic project for further development. In particular, I am interested in using .NET controls to display data in a user-friendly hierarchical grid control.The data for each hierarchical display is stored in two separate tables (I call them tblData and tblExtraInfo), and then I use a query to join the data and prepare for display (I call the query qryBOM).

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.

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 am using VS2008 and SQLite. I have created a database and several tables and am attempting to populate the tables with data from arrays.
The following code (example) works fine but stops after it inserts 30 to 50 records. I am running the VB code in debug mode and when it stops, I press pause to see where it is. It stops on "SQLcommand.ExecuteNonQuery()" and when I press continue (F5) it will insert another 30 to 50 records.
I do not get an error message. Is this a timeout issue? How do I keep the loop running to the end of the array?
Following is example code.
Dim
SQLconnect As New SQLite.SQLiteConnection()
Dim SQLcommand As SQLiteCommand

I have need for a database in my latest app, i quickly realised it had been a long time since i last used a database and am in fact very very rusty on the subject. So i decided to create a simple DataSet using the designer, i created 2 tables as follows
Table 1 is Named Map and contains a 2 dimensional array each cell containing an array of object id's of anything in that cell, and a level ID.
Table 2 contains data about these objects ie size weight and a z-order, again referenced by an object id (matching Table1)
This i did with no issues, when it came however to actually populating these tables i drew a blank. Do i have to locate the database file and edit with notepad? I presume not. Maybe i have to use an external app like sqlmanager? I seem to recall from my past that i added table rows from within the designer but i cannot find this in 2010 express

I am working on a database application. I had used Dataset to link my VB programme to a database and selected specific tables. However, I created more tables in the database and I wanted to add the new tables to the dataset. I could not find a simple way to do this, so I deleted the existing dataset and created a new one. This move has broken my VB codes. I can no longer run them as errors are shooting up. In fact, I connot view the forms in my programme anymore. I have a backup of the codes to rerun, but then I need to add new tables to the dataset.

I build xml in memory from the file, separate that into nodes for binding to different grids, works fine except the dataset is missing two tables and I can't find out why, the code below uses a stream but I've tried a ton of stuff by now, and, just using ds.ReadXml(path) doesn't work to get the proper nodes and drops all but the first major node: vs2008/vb.net project.
I believe what's going on is that the nodes have attributes ... none of the nodes that do come through have them, the "author" and "entrydate" nodes are being dropped from the string:
If (My.Computer.FileSystem.FileExists(pPath)) Then
xmlDom.xmlArchMaster(pPath, xml)
_default.ActiveSiteID = xmlDom.siteheaderNode.Attributes("id").Value
