View 3 RepliesI have an error panel that is subbed in to a page if an error goes wrong to gracefully handle and display errors.Currently, I am just appending the error messages to a string and pushing that to a label. If you have multiple errors, this gets messy.I'd like to push each error to a list item in a bulleted, unordered list.How can I dynamically generate, from a vb codebehind file, new list items inside of an undordered list element?

I want to rearrange a list of items in different orders for few times; ie: the 2nd in the list becomes the 1st & the previous 3rd becomes the 2nd, ... then the Last one becomes the penultimate one.In the next round, the 3rd of the original list becomes the 1st & the 4th of the original becomes the 2nd and so on. (That is, each item moves one rank above & the Top one goes to the Bottom)Given below is an example.Here, I took only 6 items & rearranged for 5 times only. (I should be able to use several Items and to rearrange for many times).The Original List:
(1) Alpha, (2) Beta, (3) Gamma, (4) Delta, (5) Epsilon, (6) Zeta
2nd List:
(1) Beta, (2) Gamma, (3) Delta, (4) Epsilon, (5) Zeta, (6) Alpha

I am attempting to read the results from a SQL query into a List(Of) and I can see the List.count while adding items to the List increments, however in another part of my code when I am attempting to read the List the List.Count returns 0. My List is as follows:

I'm learning how to add items from a list box to a combo box. I'm trying to follow what's going on in the function loop and comparing a boolean and selected index. I can see that it's comparing the item chosen to each item already in the combo box to make sure that it's not already there. If function finds that it's not in the list it sends back that it is true that the item is not in the list.
It then continues to the statement that adds item to the list. The code for the double click event is working fine and items are getting added to combo box. However, the code for the add button isn't functional. I'm not seeing why it doesn't work? I coded out the original code, and replaced with something I thought might work but it still isn't functional. [Code]

I have some code that adds items to a List(of Object).
Here's my original code
Dim BeaconStoryList as New List(Of My.StoryType)
Dim BeaconStory as New My.StoryType
Dim NewStories() as New Foriegn.StoryType = GetStories
[Code]....
But as soon as the code assigned "Chicken" to BeaconStory.Title, then BeaconStoryList(0).Title would also change to "Chicken".
With my second version of the code this did not happen.
It's as though it was placing pointers into the elements of the array rather than values. If that is the case, however, then why does my second version of the code work - I'm still passing in the same thing - aren't I?
I'm using the free version on Visual Basic 2008 (through school).The assignment is to populate a list box from user input text. The textbook only talks about populating a list of known items.ex animalListBox.Items.Add("dog") Which works just fine, however, we don't know what the user will input.
So, how should I be thinking about this?
I'm still learning VB.net and there is a bit of code I have added which is an array and I want to add a list of items to the array. If that makes sense. I have 6 classes two have arrays.
Here is the code from one of the classes
Public Function getItems() As Array
Return _LevelItems
End Function
How would I add the item list to this? Where do I put it? Like underneath it or in the items class? That code is in the Level class.
I have a small program that talks to a server, grabs the content from a website using a php webscraping program and then places the results in a listbox as a string. My problem is taking this string and creating a list from it. Each item in the string is followed by a | (pipe). I have included the code that I've tried below:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim str As String
Dim start As Integer = 1

I have this code to return a list of fund sources for our organization.
Dim FundSourceList As New List(Of FundSource)
Dim fs As New FundSource
If results.Count > 0 Then[code].....
The problem is that when I loop through the resulting FundSourceList all it shows is the last value. For example, if I have three fund sources (state, federal, athletic), then when I use this code to loop through all I get listed is athletic, athletic, athletic.
For Each FundSource In FundSources
Debug.Print(FundSource.FundDescription)
Next
So I change the code to this. I moved the creation of the fs variable inside the loop.
Dim results = From result In dsResult.Tables(0) Select result
Dim FundSourceList As New List(Of FundSource)
If results.Count > 0 Then[code]....
This works fine but now I'm creating a new class over and over again. It seems a little inefficient to me. Can I not create the class outside the loop and use it over and over again?
In c# I can initialize a List at creation time like var list = new List<String>() {"string1", "string2"};

I am trying to learn how to work with the different controls in Visual Studio for VB.Net in particular the List View and Tree Views. I don't have any code to show as I am not working on anything in particular just messing around with it to learn what the different controls do that weren't covered in my Intro to VB.Net class last semester.I would like a clearer explanation on how to actually use code for these controls. In particular adding and removing items from the List and Tree Views using code.

I am creating an information access system. Here the notifications created by the admin will be visible to the user through a visual basic form and sql database. I need a maximum of 20 notifications and the last created notification should appear at the top in the form. Also when the 21st notification is created it should automatically delete the 1st and so on.

I have a list of Objects. Each of these Objects contains a list of other Objects (pseudo code) :-
Private Structure Object1
dim Name as string
dim ListOfObject2 as List(Of Object2)
[Code]....
I need to sort the list of Object1 by the Value in Object2. I have a comparison class which sorts Object2 by its Value nicely.
I basically want to do what you can do for controls like the textbox where adding a new textbox automatically autonumbers itself based on the existing textboxes(e.g. textbox1,textbox2, textbox3) except for an array or some other comparable instrument.
View 5 RepliesI recently downloaded VB 2010 Express so i am quite new to the language, but i have worked with dark basic, which seems to b very similar.Anyway, my problem is that i cannot seem to correctly set out my array of a custom type/class. i am trying to create two arrays, one of available entities and another of selected entities of which the user selects the entities to be dealt with in irrelevant ways. i have creates a button (called test) which adds some entities to the available list and all the entities come back the same value but they shouldnt be as you'll c in the code. i have run the step into command a found that "available.item(#).Name = " will change all of the entity's names.As of current i am working with lists as the array kept asking for a 'new' statement but i couldnt figure out where to put it.[code]

I have this list view (which is working fine) and i want to find an efficient way of populating it in a specific order, ie by date, by identity etc.
I know i can use linq but as i understand this is inefficient. If m_batchs is a large list of objects then i will looping through this list many, many time (as linq behind the scenes loops through the object collection).
You can set listview items in a-z order and z-a order but how to set listview items in arbitrary order?
View 4 Repliesso I am working on a program with items entered into a listbox. Then when the user clicks a button it will randomize the listbox items in just a random order obviously. I have tried adding it to an array and everything but I ended up just having to start over now because I couldn't find a solution. I can save the contents and everything I know how to do that it's just randomizing the items that I am struggling with. I have searched high and low and have yet to find a conclusion to my problem.
View 4 RepliesI am trying to create a simple Word doc that when the user presses the button it takes the information in the boxes and tosses it into a template style paragraph. But my issue is that I have two combo list boxes as seen in the picture. I want to have two values in the drop down list as seen in the labels next to them but for the life of me I can't figure out how to do this in Word 2007. In Visual Studio this is much easier but I am work and need to snap this out for the folks at work. Is there an option that I can choose in the properties where I type in the values for each drop down or do I have to add them in at run time?
