Xml - DataSet.GetXML() Put Data In Attributes Instead Of Elements?
Aug 20, 2009
I have a dataset which I am populating via an Oracle SQL query:
SELECT col_id, col_desc
FROM table_data;
Then I generate the dataset, via the function
Dim ds as New DataSet
OracleDataAdapter.Fill(ds)
Now, when I get the XML of the generated dataset via:
Dim strXML as String
strXML = ds.GetXML()
When I read/display the string, it is showing as follows:
<NewDataSet>
<Table>
<COL_ID>ABC001</COL_ID>[code]....
How would I be able to accomplish this? I would read the rows from the table in the dataset and construct the string?

I'm trying to create a treeview in a VB 2008 project that shows all the elements and attributes of an XML Schema.The MSDN documentation for XML schemas seems to imply that by loading the schema into an XMLSchemaSet and compiling it I should get access to all the elements and attributes with their values but this doesn't seem to work in practice.
Using a for loop such as:For Each elem As XmlSchemaElement In compiledSchema.Elements.Values
I can use elem.Name to get the element name (and attribute name with a similar nested loop) for a simple type but this doesn't work for a complex type.Whenever (and however) I try to get values for complex types I hit a brick wall.

I have given the local name of an element or attribute and the schema for the document. What is the easiest way to determine the basic datatype of the element or attribute. By basic datatype I mean the xs:string, xs:date etc. (The built in data types for the xml schema.) One of the problems I face is that it is rare for the elements type to be one of the basic built in types. 99% of the time it is a complex type that 50% of the time refers to another complex type that refers to another complex type and so on.
A simple Example for this schema: I want to find the basic type for Employee/Person/Name/LastName (determine that LastName is xs:normalizedString).
In the schema Employee is defined as an xs:element and type="bns:EmployeeType"
EmplyeeType has a Person element defined but it is type "PersonType" and then Name in person is NameType which is a complex type that extends GeneralName type that is type BasicNameType and that type finally defines the LastName which is of type "LastNameType" and on and on. There also definitions etc. I am currently writing a parser using linq-to-xml to get at this but it isn't easy or pretty. I have searched for other solutions and haven't found any but I fully admit my XML/schema/XPath ignorance. Is there an easy way to get the basic type for elements?

I have two user controls that need to add a class atribute to the body tag of my page, however they currently over write one another if I just use Body.Attributes.Add("class","value") So I need to check if the class attribute exsists and if it already contains the value Im going to add.
If Not Body.Attributes("class").Contains("value") Then Body.Attributes.add("class", Body.Attributes("class") + " " + "value") End If
EDIT: The contain constraint doesnt return the expected value, resulting the the class not been concatinated, Example: add class "dog" then I a different instance of the same control tries to add "dog" but the contains("dog") returns false

[Code] Somewhere my system haves a function that returns a DataSet with the books of a certain subject and all the Authors that wrote such books. I need to show the book's attributes in some textboxes inside a Form. I use a BindingSource to display the ISBN, Name and Subject of the books in a textbox, yet I don't know how to display the author name of the book I am currently viewing in a TextBox, taking into account I already fetched the Author into the DataSet.
Its pretty much the Child/Parent display problem somewhere discussed in the codebank, but kinda backwards, the thing is that I;m navigating through the CHILD records here, not the parent, yet i have all the data needed in my Dataset.

Dataset's ReadXML() method would read an XML document. But how would we skip certain columns? [Code] So, if I use ReadXML(), it would read the whole document and the dataTable would have "id" column, "name" column and "price" column. But I want to have only "id" and "name" column. How can I skip certain columns from reading it?

I'm wrangling with issues regarding how character equipment and attributes are stored within my game.My characters and equippable items have 22 different total attributes (HP, MP, ATP, DFP). A character has their base-statistics and can equip up to four items at one time.[code]Final character ATP in this case would be 88.I'm looking for a way to implement this in my code. Well, I already have this implemented but it isn't elegant. Right now, I have ClassA that stores these attributes in an array. Then, I have ClassB that takes five ClassA and will add up the values and return the final attribute.However, I need to emphasize that this isn't an elegant solution. There has to be some better way to access and manipulate these attributes, including data structures that I haven't thought of using.I should note that there are some restrictions on these attributes that I need to be put in place.E.g.,these are the baselines.For instance, the character's own HP and MP cannot be more than the baseline and cannot be less than 0, whereas the ATP and MST can be. I also currently cannot enforce these constraints without hacking what I currently have :(

in the sense that MVC does not complain about my protected inner abstract Metadata class, and the model validation still works:
Partial Domain Object, generated by a tool:
Partial Public Class SampleDomainObject
Private _id As Integer
[code]....
I did this because I didn't want to have to implement actual properties with backing fields, getters, and setters in VB.NET for the Metadata class to keep the maintenance to a minimum (I'm on .NET 3.5, no auto-properties for me).What I'm worried about is that having a protected abstract inner class could be confusing to others using this domain object outside of MVC (my domain objects are part of a shared data access framework).

I have tried everything I can to get beyond this error which shows below as <<<<< error here. It is trying to fill a dataset from a data adapter. If I change the SELECT statement to just SELECT * FROM xTable I get the correct number of records in each table. But anytime I try with a more complex statement I get the error message shown below which indicates System.Data.Common.DbDataAdapter.Fill(DataSet dataSet. I've completely erased all data and entered a new set of test data so I know there is no problem with relationships. Each table has primary key which is foreign key in other table. IS there something wrong with the Imports section: Imports System

I have two Datagrids, One grid has all the customers garments on it with style number and contact length. The other grid has the users who have garment issued to them. the style number is in both grids. I need to loop through the users grid and say if the contract number is 1 from the first grid then the contract date on the second grid will be todays date + 365 days (year contract) I have looked at using a stored procedure and also a for each command but I am just getting stuck with it all.

I created a method and pass the element type, id, and any inner text that instantiates a new html element. The last statement: Me.Controls.Add(element) adds it to the end of the page, but I would like it to be inserted in a specific position (between 2 divs within a form). What I am describing is very similar to this post on SO here, although it was for javascript.

I have an access database with one table and 4 or 5 different fields.
All I need to do is be able to be able to use a loop to read the values in a specific row and column and store it in a variable (or array).
I don't need the code for the loop or anything, just the syntax for reading the value of a specific row and column in a table to a variable.

I'm trying to write a simple game ui, it is grid/tile based, and i have the grid built using grid column and row definitions and I'm successfully placing objects in various grid locations. I am currently stuck as trying to build the player object. I want a single object reference to represent the various components of the players piece.
Currently I am using a polygon to represent the piece on the grid. Eventually I want to replace this with images or something. I want to add in properties for what weapon and armor it has equipped I want properties for health
Essentially in code i want something like this
dim player1 as new playerobject
player1.polygon.points = 0,0 60,30 0,60
player1.health = 100
[Code]....
I can instantiate all this as separate variables etc, but I'd like to have a singular reference that contains all the variables, properties, objects, controls etc.
I'm using vb .net in vs 2010 (and no, I'm not looking to write in something else)

I have the following "contact" data (exampled below) stored in an xml file.I've created a frmContacts windows form and placed a list box control inside it.I'm new to the list box but plan to have the users manage the list by letting them add, delete, and pick from it. For searching there should also be a sort function/button (by last name then first name).If the user deletes from the list the corresponding data in the file will be deleted.If the user picks from or adds to the list, I'd like to find the best way to populate the corresponding data elements on another form (i.e., in their respective text boxes). This will include the ability to edit/save from this other form too.
<?xml version="1.0" encoding="utf-8"?>

I have a situation where I have an xml document that has a bunch of elements that I basically use as data variables. I populate the variables from various sources and then transform the xml file to an html file for user viewing.having to remember the names of all the data elements in the file is somewhat tedious. Is there a way to generate a strongly typed xml document object so that one can simply dot into the various data elements?

I have a situation where I serialized data from a dataset to an xml file as a method of backup.I am trying to get the data deserialized back to the dataset.But for some reason, I cannot get the data to persist back to the DB.I don't receive any error messages either.The first chunk of code is the serialization code and the second chunk is the deserialization code.I can show that the deserialization back to the dataset is complete because this code in the 2nd block DataGridView2.DataSource = Movie_dbDataSet.movie_tb - displays the data in correct form all it is all there in the datagridview2.I call the update method but it does not get persisted back to the db.[code]

I created a dataset in Visual Studio 2010 containing two tables: tblCategories and tblAnswers. tblCategories has two columns: CategoryNumber (AutoNumber and primary key) and CategoryName. tblAnswers has three columns: AnswerNumber (AutoNumber and primary key), Answer, and CategoryNumber. The CategoryNumber columns in each table are related. I have a command button which I want to use to add a record to the CategoryName column in tblCategories with the data typed in a textbox. When I try to access the dataset to add a new row(dataset.tblCategoriesDataTable.NewRow), the NewRow method isn't present. I've done some reading which suggests that I need a TableAdapter, but it seems like that is for connecting to an external file because I have to select a connection. I have no external SQL files or database. I want the user to be able to create a database within my program.

How do you plot data from a dataset or datatable. I have loaded a dataset with data from the database and now cannot do the plotting. When I tried: myChart.dataContext=ds("myTable").defaultView, no chart shows. If I replace: dataContext with: dataSource, I get an error. I am using WPF not Windows Forms.
