Nested Xml To Table
Apr 2, 2009
I have an XML file which is a multitable nested xml file (.Tables.Count returned 12 tables). I would like to have all of the xml contents in one table or, if not, select different columns from these different tables (that are stored in XML) and put them in one table. As I understood Datagridview only allows only one table at a time. Is there any way to create a new datatable by joining exsting tables from XML?

I have a data table whose one column is related to a column of another table. I have a listbox in a form which shows a column (which is sorted by another column value by ORDER clause) of the parent table and other columns are in textboxes. The child table is represented by a datagrid. When I add a new item in parent table and click save, the newly created item is listed at the bottom of the listbox violating my ORDER clause. When I wrote some codes to fill data again after updating, it shows an error message[code]...

I have an outer listview and inside its itemtemplate an inner listview. Each has its own SQLDataSource. A Id field from the outerlistview works as a select parameter for the second listview.
When stepping through with the debugger it works perfectly, unfortunately the rendered page only contains data from the outer listview. It appears the databinding of the outer listview fires and renders the page (including the inner listview) before the codebehind can provide a where parameter to the second listview. The aspx page is below.

I've a large table of Items and I need to organize them by Category, then by Year and then by Month.Item has CategoryID and Dated properties.I got this far:
Dim Items = From Item In DB.Items _
Group By CategoryID = Item.CategoryID _
Into Categories = Group _
Order By CategoryID
But where I put the:
Group By Year = Year(Item.Dated)
and the
Group By Month = Month(Item.Dated)
The final result should be something like this:
For Each Category in Categories
For Each Year in Category.Years

All I would like to do is populating a DataGridView with 4 columns (Name, Age, Language and Artwork). Each of which containing its appropriate value whereas the latter will contain all pictures... See what I mean?

I'm working with a database that includes a table called MenuItems. The table is hierarchical, so an item can have child items under it. A record's ParentID corresponds to the ID of the parent record, or the ParentID can be 0 if the item is on the top level.What I'm trying to do is create a VB.Net application to populate a TreeView with the records in my MenuItems table, using the recursive function ListSubMenus in the code below:
Code:
Private Sub ListSubMenus(ByVal ptvnParent As TreeNode, ByVal plngParentID As Long)
Dim strSQL As String

I can't seem to find a lot on how to use events in nested objects. I suspect that I should have access to the events in the nested objects through intellisense if I had done things right. I have many objects with 50 or so properties and I would like to access them with out adding handlers for each one and additional events in parent objects.
Example:
Public Class Form1
Dim WithEvents myCombinedClass As New CombinedClass

I am constructing some XML using XML literals. I have a function which returns an XElement.
Function RootElementFormattingFunction() as XElement
Return <Root Data="foo"/>
End Function
In reality it is a bit more complicated than that, but it is called from several places. Now I have linq sequence which generates a set of nodes which I want to make children of the XElement returns

I am working on a project that requires that I use nested case blocks. However, I am not quite sure what this looks like. And for whatever reason I'm having a hell of a time trying to find the answer through google. Are nested case blocks like nested if blocks? Or are they something completely different? More information on the project can be given if needed.

I have a couple of controls that are set to runat="server", but are showing up as "not declared" in the vb code behind. They are not being setup in the designer.vb file at all, even if the design.vb is re-created.
The only thing that I can think might be causing this is that the controls are inside of a custom control. The code looks something like this (it has been modified because of NDA):
<abc:MyCustomControl>
<additionalItems>
<asp:CheckBox id="coolCheckboxOfPower" runat="server" Text="Triple Rainbow!">
[Code]....
So using the example above, if I try to use coolCheckboxOfPower in my vb page, it says it is not declared.
It has been suggested to me that asp controls cannot be nested. Is this true, and if so, how do I get around that?

I have a datasource that needs to gather information for a label. These are both inside of a DataList that is connected to a different DataSource. When I debug my application, the value is Nothing. I thought I had the verbage right since there are no squiggly lines, but it isn't working.
I tried FindControl("dsPicklist") and DirectCast(FindControl("dsPicklist"), SqlDataSource) but neither one gets a value returned.
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
' Find the nested DataSource control in the DataList.

I am working in a proprietary language based on basic on a measuring machine. I delibritly set the first two checks to fail for testing purposes. The first set of ifs for size X works great. When the code is run and it gets to Size_Y, if the operator picks "no I don't want to remeasure" (returning a 7) the code jumps all the way to the last end if. I suspect I have improperly nested my Ifthens, but I can't see it.

How do you do nested recordset loops in ADO.NET? In ADO, you could just open one firehose cursor for the outer loop and a static, client-side, read-only cursor for the inner loop and nest the loops. But you can only open one DataReader at a time and Datasets aren't read-only.
'Classic ADO Code
Dim rsOuter as New ADODB.Recordset
Dim rsInner as New ADODB.Recordset

I've seen people discourage other from using nested classes, because the make things more complicated and are evil and whatnot.But I want to know what possible justification there would be for using a nested class and if there are any possible benefits for using them(or structures for that matter).
