Xml - Iteratiing Through The Info/test Items And Then Iterate Again Through The Test_properties?
Mar 4, 2012
I am iteratiing through the info/test items and then want to iterate again through the test_properties, but I don't know how.the properties are never a fixed count, so it could have 1 property or 200.i need the type='" attribute and the value of the property.I use this so far:
Dim Xml_Document As XPathDocument = New XPathDocument("e: est.xml")
Dim Navigator As XPathNavigator = Xml_Document.CreateNavigator()
Dim ns As XmlNamespaceManager = New XmlNamespaceManager(Navigator.NameTable)[code].

I have a ListView with a CheckBox as one of the columns, bound to a boolean property of a custom object. I'm trying to figure out how to iterate through the items in the ListView and check all the checkboxes. What I have so far is below:
XAML:
<ListView x:Name="MyListView" DockPanel.Dock="Top" Height="275" IsSynchronizedWithCurrentItem="True" ItemsSource="{Binding}">
<ListView.View>

I am using the winform datarepeater control from vb.net power pack. All of the items on the repeater are readonly except for a checkbox column.I want to iterate over the items and find out which checkboxes are checked. I can't find a collection of datarepeateritems on the control and help is scarce.

I can't seem to find any answers that work. Here's the setup:
Info class: Public Class ProductStageInfo
[Code]...
maybe I just don't understand the whole collection/index/thing. All the examples I've found are regarding single dimension collections - 'how to find name within this collection', and the responses use strings to search through them, but somehow the Info class is being treated differently, and I'm not sure how to translate this..

I have a table being imported into my VB application that has 3 columns. I have written code to import the table, and have written code to display on the first column (country) in a list view.
What I want to do now is have the user select / highlight an item in the list view, and have the third column (currency) related to that selected country appear in a text box when a button is clicked.
Here's the code I've written that successfully imports the data and displays the first column:
Private Sub frmCountry_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim dataCountry As New DataTable()
[Code]...
Should I perhaps use something other than a list view?

Currently developing an automation tool to test new desktop OS builds at work. Need to be able to open menu items on toolbarwindow32 windows (main menu of explorer windows). Now this requires retrieving information of all the buttons on the toolbar, obtaining the button ID of desired menu and sending a WM_COMMAND message with the ID. I'm having trouble retrieving button information.Now im using openprocess, virtualallocex to allocate virtual memory in the target process, and then sending the TB_GETBUTTON message with a pointer to the allocated memory then reading out the result. Allocation and the send message works fine but reading the processmemory back out is failing but not returning an error code, getlastwin32error returns nothing either.
<StructLayout(LayoutKind.Sequential)> _
Public Structure TBBUTTON
Public iBitmap As Integer[code]....
As mentioned above, the read process memoery call fails, the return value is -1 The documentation states it returns 0 for fail, non zero for pass. Wondering if the problem lies in incorrect use of types in pinvoke calls or the struct tbbutton is incorrect, or my use of a pinned pointer is wrong,or whether I need to use adjusttokenpriviledges to ensure I have rights.Though I'm running under admin and examples similar to this don't use it.
Relevant documentation

I want to know how to test the 1st list box if it has items more than the other list box but by one item, here is what i have: If lstInvisibleTv. Items.Count > lstInvisiblePc.Items.Count Then it works good if the lstInvisibleTv list box is greater than the other list box by one but it also works if it is greater the other one by one or more which I do not want. I want it to work just by one.

I am working on a media player, and I would like to setup a local playlist feature. I am using a single ListBox and its "Display-" and "Value-Member" properties.

I am trying to do is fill out a form with certain info, put the info into an array, and write it to a listbox using loops, arrays, and maybe a function if I need one. This is for VB2010 and here is what I have so far... I think there are ways to make it shorter but I cannot figure it out.... maybe just brain dead from all the coffee I have been drinking!

how to correlate info from a textbox based on a listbox item selection. For example the user will select an item from the listbox, enter say the length of a song in the textbox say 2:00 for song #1, select say song #2, enter the song time for that song say 3:00, click on song #1 again and have the same textbox display the length of that song and be able to do that until there are no more songs on the list.

Probably a dumb question, but can you write a unit test project in one language to test against another project in a different language?I'd like to translate one of our VB assemblies into C#, but want to build unit tests to verify the results. I've tried to set a unit test project up to do this, but I can't seem to access the VB code within a unit test... I can't figure out if I'm just missing/doing something stupid, or it really isn't allowed.

I'm using a DynamicJsonModelBinder from a blog post to pass my JSON data from JavaScript to my ASP.NET MVC Controller as a DynamicJsonObject.
Have a look at the blog post: [URL]
I converted it for my project to VB.NET : [URL]

This works. In my controller, I can access my jsonObject like this: obj.ID '123
But I haven't got an idea yet how to iterate through all properties. I can get all member names as a IEnumerable String Collection (obj.GetDynamicMemberNames()), but how do I use the TryGetMember method to access the value of a member ?

I have a VB Web Application with a bunch of textboxes on it in Default.aspx (Using the basic template in Visual Web Designer 2010 Express). I'd like to iterate through those textboxes using some sort of VB solution if at all possible and clear them when the user presses a button. I've tried using something like this:

I need some help with a LINQ query in VB.Net, please.[code]This works, and returns me the data I need to work with. Now I want to iterate through the groups, using a For Each construct. like this: For Each x In drivers Next...However, the compiler is barking at me, telling me that the "'x' is not accessible in this context because it is 'Friend'."

I have a simple XAML file with a grid in it and textboxes. But when using my code it does not find the textboxes by iteration.
VB.Net:
Dim ctl As FrameworkElement = Me.MainWindow

Dim ChildrenCount As Integer = VisualTreeHelper.GetChildrenCount(ctl)
'ChildrenCount is always zero
For i As Integer = 0 To ChildrenCount - 1
Dim Child As FrameworkElement = VisualTreeHelper.GetChild(ctl, i)

I have a BindingSource bound to a DataTable.
I use the BS Filter and would like to iterate the filtered dataset of the DataTable using the Bindingsource.
I know I can do a MoveFirst and the MoveNext and each time using the BS.Position get the correct row in the underlying DataTable. But how do I know when the sets ends? I'm sure there must be such a property, but what is it?
