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

I can get it to tell me if the ISBN I entered is valid or not, but there is a second part I need that I keep drawing blanks on. I need to be able to enter an ISBN with a missing digit marked by a "?" in the textbox i am entering the ISBN in. For those who don't know what an ISBN is it...
An ISBN (International Standard Book Number) is a ten digit code which uniquely identifies a book. The first nine digits represent the book and the last digit is used to make sure the ISBN is correct. To verify an ISBN you calculate 10 times the first digit, plus 9 times the second digit, plus 8 times the third ... all the way until you add 1 times the last digit. If the final number leaves no remainder when divided by 11 the code is a valid ISBN.
1.Write a program that reads a ten digit number and validates it.(DONE)
2.Write a program that reads in a valid ISBN with a single missing digit, marked with a ?, and outputs the correct value for the missing digit.(Ehhh....)[code]So i need help making it so i can input a ISBN with a missing digit marked by "?" and output a valid ISBN with missing digit.

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 ?

I am trying to develop a report that displays the result of a query that returns two tables. The first table is always a single row of values, the second should be a grid. I can get a report to display either independently, however it will not allow me put them both on the same report.

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 have some problem with working with tables which were created on previous form. Say we have a form Customers in which Customers are displayed in datagridview.Now to create or add ne customer to this customer table on sql server, another form is opened.In this form user enters all data like customer name, phone number etc. when changes are made to the sql server using a stored procedure this form is closed now I want to show this newly added customer in the datagridview of the previous form.Right now what I am doing is creating data set and command et. and again fetching data for all customers from sql server.

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....

-<Meetings xmlns="" Jurisdiction="VIC">
-<Summary MID="MR_20110801">
<VenueName>ECHUCA (VIC)</VenueName>

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.

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'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.

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.
