VS 2008 Displaying A List Within A List In A DataRepeater?
Feb 2, 2010
Firstly i apologise for another topic on a subject i have created already but this is a slightly different question and not related to LINQ at all despite the fact the code uses LINQ (the linq works fine and creates a List(Of Test) where each 'Test' contains a List(Of TestList) This data could be anything i guess and could come from an array or a database rather than xml literals.Ok, essentially i have a list which contains a list and i wish to display all the properties (List and list within this List) onto a DataRepeater Control. I have developed a testbed to get this working so i can implement it into my main application. Firstly I'll show the current code and how to construct the form and after that i will explain what i have tried and what i have had happen from these trials over the last week.
Public Class Form1
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

I currently have a list of words in a text file sorted in to alphabetical order and put into lower case, but I would like to be able to also display the line numbers on which these words are associated with.. but only one instance of.
For example,
"This is a random text
file that I
have just made
up this second"
[Code].....
As you can see above, I would like to show that "this" for example appears on line 1 and 4. Hopefully tabbed so that it keeps a nice look to it.

I am trying to understand classes in VB 2010. I am a bit confused with displaying information from a list into a listbox.When I run the following code, the word collection appears in my list box. How do I drill down into 'hostnames' to display the info I want.
Public Class computer
Private _HostName As String
Public Property HostName As String

I could not include the code since it's too large but here is the LINK. I have most of it working. I just need to know how to display the passenger list in the ListBox when the flight number is changed from the ComboBox.

This is what I'm sure will be the first of many noob-ish questions from yours truly... I'm studying as a mature student for a Computing Degree (encompassing web design, hardware, programming and systems analysis). The programming seems to be my weak spot this year. I enjoyed C++ last year, doing basic console applications, but progamming visually with VB in Visual Studio 2008 I'm struggling!

I think (?) this is about object design, and perhaps about structural and/or creational patterns. But a bit hard to say when I only know a couple of patterns yet.[code]But... what if we INSTEAD want each Product instance only to (in some way) refer to one instance of a specific list of Components. So we wan't to save the products list to one file, and the components list to another file. Then would I build the objects the same way, or different? So let's then say we have now Class B as below. [code]
1. Will not need to update each component variable of the products list when the components list changes.
2. If the Product object shall be shown in a DataGridView, for editing properties, it seems easier to implement the selection of the component property.
Is this wrong approach? Is it suitable in some cases, and if so, when? Are there other solutions I perhaps am not aware of that would be appropriate? Is this about structural design patterns? and if so, can the alternatives above be catagorized to some pattern type? I don't really know exactly what I'm looking for.. But I think probably I'm looking to understand whether the object design will be determined by the way the objects are saved.. And if i shall save the objects by serializing to file, vs saving to a database, would I create the business objects differently?

I want it so every time I click an ITEM in the Listbox it displays ALL the data into the textbox. I know there's an easy way using table adapters and binding the listbox, but I'd prefer to do it this way for my project.
So this is what I got.
Lst.DataSource = ds
Lst.DisplayMember = "tblStudent.FirstName"
Lst.ValueMember = "tblStudent.StudentID"
[code]....
It only adds the first rows details to the text box when I click the second record the first rows details are still there.

Ok i'm trying to declare a global list of type T (or is it <anonymous type>) i declare it in a module with something like Friend query As New List(of {whatever type i try}) the app takes some xml and parses it into a list but i need this list available to other classes and methods within the app, everything i have tried fails resulting in an error like Value of type 'System.Collections.Generic.List(Of <anonymous type>)' cannot be converted to 'System.Collections.Generic.List(Of {whatever type i try})'.
What would be the correct way to declare a list of this type? is there another way i could do this?

What I am trying to accomplish is this: I have a login page were a student logs in. After the login the student will be taken to a student user page. This page has 2 list boxes. The first is showing the exams that he has passed and the other shows the exams he has yet to complete or fail. I can not get any data to display in my list box. If I can figure the first one out I can do the second one easily but I can not get the first one to work. Here is my code that I have so far:
Private Sub Student_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Label1.Text = "Welcome " & _passedText

I am using a ListView control to display Pictures along with description and caption. I used to save the full path of the image in the url field, so when I display them in the ListView I don't need to edit anything. Now I am using something like:
HttpContext.Current.Server.MapPath("~/photos/") + savedURL
How can I edit my ListView to make it show the images?
I used to do the same to GridView when in GridViews RowDataBound event I manipulate the contents like:
Dim photo As New Image
photo.ImageUrl = "~/photos/" + e.Row.Cells(TheCellNumber).Text
e.Row.Cells(0).Controls.Clear()
e.Row.Cells(0).Controls.Add(photo)

I can't seem to get the syntax right for this. I have a structure stored in a generic list and when it displays I get this "GenericList_T_.Form1+stuMotorInfo" in the messagebox. I've tried a few things and get roughly the same thing.
Here is the code:
Option Strict On
Public Class Form1
Private Structure stuMotorInfo
Public MotorId As String

So we are just starting to learn about list boxes in vb1. In this program the user enters up to 10 scores and after each input (decInputScore) the total score so far has to be calculates (decTotalScore) and then of course when all the scores are entered, at the bottom the final score it calculated. (decFinalScore) (decFinal). I'm not exactly sure what I'm doing wrong, I can't get it to calculate the correct total scores after each input, and I'm getting 0 as the final score. Here is a visual of what the form should look like: the black square is (btnEnterScore) a pop up message box comes up in which the user enters each value when clicked.[code]

I am trying to get VB.NET XML Comments to work with IntelliSense, and maybe it doesn't work the way I think it does.

This should, when you are typing in a function, display the "Get or sets the Patient Code" then below that, it should display a list of bulleted items with "Validation:" as the header? Maybe I am doing it wrong, but it doesn't seem to be working correctly.

I have a table in a databases that contains 12 rows. I am loading a runtime dataset with that table. The result are displayed on 2 different controls. The first one is a DataRepeater and the second one is a DataGridView. The DataGridView displays all 12 rows just fine.
The DataRepeater does not. Some of the 12 rows will be blank and some will have the data. Sometimes I won't see any data until I completely cycle the scroll bar to the end and then back and still some of the 12 rows will be blank.

I have a list of string. When user inputs chars in, the program would display all possible strings from the list in a textbox.
Dim fruit as new List(Of String) 'contains apple,orange,pear,banana
Dim rx as New Regex(fruit)
For example If user enters a,p,l,e,r , then the program would display apple and pear. It should match any entry for which all letters have been entered, regardless of order and regardless of additional letters.

I have a form displayed where a user can can select a 'function' from a list box. That 'function' has a corresponding ID number which I need to be able to take and use later in the code.The List of functions is preset (about 150+ them and the IDs are already assigned (so I can't just use the index).So if the user selects "Function A", I need the code to set a variable to, for example "42" (or whatever that Funtion's ID is).
I was going to do this using listbox.item and listbox.itemData, but I'm using VB.Net in VS2008 and I understand that function is no longer present (to add ItemData at design time).Here's where it gets complicated. When the form loads it looks at the variable containing the FunctionID and if there is one present, I want it to populate the co-ordinating FunctionName. I can do that if I know the index number, but I don't know how to look at the FunctionID and return it's index (all FunctionIDs are unique).
A) store the info, either in the Listbox using ItemData, in an array (but I'd prefer to do it at design time), or some other way you might suggest.
B) cross-reference the ID and display the name in the listbox when the form loads.

When an item is selected from the list it displays in the text field of the combo box and I want to clear it without clearing the items in the list. I've tried [dropdown list_name].text = ""[Eg:- CBSelect.Text = ""] but it doesn't work since the text entering field in a drop down list box is read only.How should I do that. By the way, I'm coding in VB.NET 2005 so please give answers in VB.NET 2005.And my selection is from combobox its clear. same combobox property ( DropDown style = DropDown List ) text is not clear.

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?

I have a gridview that is bound to a datasource on a Windows Form (VB.NET). The grid displays a list of "certifications", and each "certification" can be associated with many languages. So in the grid, I'd like to display "languages" as a column, and display a comma delimited list of the language names for each "certification".
In the "certification" class, one of the properties is a list of "language" objects, and each "language" has an ID (guid), name (string), and value (integer).
So in the datasource, I have the list of "languages", but I can't figure out how to display them in a column on the grid. The gridview won't let me add the language list property as a column.
So is the ONLY way to add a new property on the "certification" class, which returns a string that contains the comma delimited list, and show THAT on the grid? Or is there a way to display that list of "languages"?

II am trying to create a toggle button that switches a list to a range and then back to a list if needed. I am able to get it to do both but when I add an item to the list, convert to a range and then convert back to a list it leaves off the last items I entered.I tried to work in a code to select all cells but I must not be putting it in the right place.This is what I have so far:
ActiveSheet.ListObjects.Add(xlSrcRange, Range("$A$3:$AE$7"), , xlYes).Name = _
"List1"
I realize the problem is the $AE$7 (the $A$3 is correct)

In VS 2008, VB.Net, I am successful connecting to a local SQL Server (version 8) and seeing all tables/views/procedures in Server Explorer. The local OS is Win XP Pro SP3. I created an ODBC data source to a remote SQL server (also version 8) with a database of the same structure as the local one. The connection tests out ok. The remote computer runs Windows Server 2000 SP4. In the VS 2008 Server Explorer I add this ODBC source. When I click on the plus-signs to expand items, neither the tables nor the views show anything, whereas the full list of procedures appears. Is it the old SQL Server version? Is it the old Server OS version? Something else alltogether?
