Chart Control - Bind Data To Different Series From Tables In DataSet?

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.

Inserting Data In Multi Tables Using Details View In DataSet

Mar 27, 2009

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?

Timeout Using SQLite - Create A Database And Several Tables - To Populate The Tables With Data From Arrays

Jul 25, 2012

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.

Populate Tables In A Dataset?

Oct 12, 2011

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

VS 2010 Add To The Tables In A Dataset?

Apr 13, 2012

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.

Dataset Tables Missing From Xml Input?

Nov 3, 2010

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

Forms :: How To Create DataSet And Tables From XML

Aug 4, 2011

I have an XML file that has a basic hierarchical structure about horse racing. It has a summary of the tracks, some data about each track, then a list of all the races at each track racing that day. So lets say there are 10 tracks, and for each track there are 8 races. This is a snapshot of the data....

HTML
-<Meetings xmlns="" Jurisdiction="VIC">
-<Summary MID="MR_20110801">
<VenueName>ECHUCA (VIC)</VenueName>
<Type>R</Type>
<Events>10</Events>
<Track>DEAD </Track>
[Code] ......

I have written the code to pull down the data into a data store, but I dont know the BEST way to put the data into a set of tables. My first thought was to traverse the nodes and add rows into tables but I figure there must be a native VB process that reads the xml and puts it into the the appropriate table. How to code up the process for getting the data into a set of tables that match the xml. So lets say I have a Summary table, I would like all the data about each track to go into that table. Then I would have a Races table and have the data for each race go into that. What I have done already is import the xml into Access to create the tables (which was a breeze!) and then link that data source to my project. So I have the tables already built.

Why Can't Access Tables In A Dataset By Table Name

Oct 25, 2011

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?

Inserting Records To Two Separate Tables Via DataSet

Dec 19, 2009

I've got a form where a user enters data. When the user submits that data, it inserts a record to two separate tables via a dataset. One of the records has no problem being saved into the database (in the table it was put into), but the other record seems to temporarily be in there (according to a third form), because it exists for the duration of the application, but when I exit, and then check the database, it's not there, and it's not shown on the third form when I restart the application again either.

Populating A Dataset From The Tables That Are In An Access Database?

May 7, 2010

I have a database that has tables in it. Tables can be added to this databse programatically as well as the data that needs to be in those tables.I need to be able to query that database to get what tables are in it, place the names of those tables into a listbox so that when a user clicks on the name of the table, It will update a DataGridview with the data that is in that table in the database.I assume that you would need to build a dataset at runtime based off of what tables are in the DB, but i have no idea how to do this.
