Creating A Big List?
Jul 20, 2011
I want to create a big list box that has lots of default values in many lines so they can then be edited later.Right now I have in my initializer:
Dim counter As Integer = 0
For counter = 0 To counter = totalNumber
listBoxThingy.Items(counter) = ("DEFAULT DETAILS TO BE COMPLETED")
Next
with my list box called listBoxThingy and totalNumber a previously defined constant of how many items I want in my list box.yet when I try to run the code I always just end up with the first list value containing the text.Even if I put a counter=counter+1 it still only gives me the one completed value of my list box?

I would like to know how I can get the list of possible choices to Intellisense for my class object, like it does with MsgBox.For example, when creating a message box you type MsgBox "Test Message Text", vbYesNo, "Test Message Title".In typing that, when you type the comma just before the vbYesNo, it gives you the possible selections for button types in a drop down list: i.e., vbYesNo, vbOKOnly, etc.I have a class called clsKeyState. what it does is turn on/off/toggle key states, such as CAPS LOCK, SCROLL LOCK, NUM LOCK, etc... I have set my property for it as Get/Let "State". When I call it to set a key to on/off I will be doing it like this: KeyState.State WhichKey, On/Off/Toggle.I would like the WhichKey part to automatically display all the possible selections that I define, such as CapsLock, NumLock, Scroll Lock; and I want the On/Off/Toggle to display those specific items also (On, Off, Toggle). I will be using the ability to create these displayable options for many more things in my project than just this one simple class.

So I have a program that is supposed to support a small business. I have the work completed and the professor said it was correct but I wanted to go do a little extra. Basically, on the Order screen, you begin to type the name of a customer/supplier/employee into a text box and a list of names that fit the criteria pops up in a list box (lbMatchingAccounts). When you select it, you can hit enter new order and be transported to the Order Details screen to enter the new order.

I want to create a sorted list, where I enter a name in two separate text boxes(Jones, Brown) and their values in two other textboxes(200,500), then in a fifth text box I enter one of the names and it gives me a messagebox with its corresponding value. Here is my code below.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim saleslist As New SortedList(Of String, Decimal)

I'm trying to create a small program where someone would select one of five items from a list box (Hot, Medium, Mild, Sweet, Zesty). When they select this, they then enter in a qtyTextBox the quantity they want, ie.e, 1, 2, 3, 5,... Then they the Calculate Button, which then the total would go into the preDiscountLabel box, where it would calculate the amount they want * the sale price. Here is the Price Listing:
Hot - 3.19
Medium - 3.09
Mild - 2.98

I want to create a generic list - but I want to specify the type at runtime - is there a way I can do this? using reflection perhaps?Something like this...
Public Shared Sub create(ByVal t As Type)
Dim myList As New Generic.List(Of t)
End Sub

I'd like to create a list of an anonymous type, for example:
Dim dsResource = New With {.Name = dsResourcesEnd(index).Last_Name & ", " & dsResourcesEnd(index).First_Name _
, .StartDate = dsResourcesStart(index).Day _
, .EndDate = dsResourcesEnd(index).Day}
I have created that anonymous type. Now I'd like to add it to a list of that type. How do I declare a list of that type?

I am using MS Visual Studio 2005 and SQL Server 2000 to develop an application. I wish to make a list of radio buttons when I fetch a particular column from a table. for example, I fire a query that returns to me 10 types of candies, (yummy!). I want to show these candies as options on the form. I want to use Radio Buttons. Now the number of candies are not fixed, it can be any number (less than 15-20). So I wish to dynamically create this 'Array of Radio Buttons' on the form.

Im working with VB 2008 express
I have several pictures on my form designer and a large textbox to the right of them. When the user clicks the pictures I want a list to be created in the textbox. I was able to get a single button posted into the textbox but when a second picture is clicked it over rides it and replaces it. I wasn't sure if i should be use some kind of loop or not.

I am creating a List(Of String), always of size 9.This list contains True/False values. I need to go through this list and find the 3 values that are True (will never be more than 3, but could be less) and then set 3 string values in my code to the 3 index's of those values + 1.
Here is my current code:
Private Sub SetDenialReasons(ByVal LoanData As DataRow)
Dim reasons As New List(Of String)
With reasons
[code]...
I had 3 True's next to each other in the array and the code failed with an exception saying count must be positive or something.Now if there are less than 3 True's, it should set the remaining DenialReason's that haven't been set yet as blank (however they are set as blank in the constructor already to account for this).

I have been trying to figure out how to get my code to work. (It was a homework assignment which has already been turned in but I am determined to get this code to work.)I have a text box titled txtSearch and btnClick.I need to search a list box for a city name and then have it displayed in a message box. If there is not a match then I need to display an alternative message box stating there is no match. City is in the list box starting at 16.The text needs to be case insensitive.I am only getting the message "That is not a valid city." for any entry that I type into my txtSearch even though I know it should be a match.
Here is what I have for code
Private Sub btnFind_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnFind.Click
' Declare variables to find text on txtSearch when button clicked
Dim length As Integer = txtSearch.TextLength
Dim value As String = txtSearch.Text.ToUpper

I'm having trouble creating a global array that i can use in other functions.
I have this code right under "Public Class myClass":
Dim LoadedPlugins As Array
Then in a function I have this:
Dim PluginList As String() = Directory.GetFiles(appDir, "*.dll")
For Each Plugin As String In PluginList
Dim Asm As Assembly
[Code]....
Now obviously that doesn't work, how can I add the tmpPlugin to an array or list so I can use it in other functions?
The main thing I need to be able to do is loop through all the loaded plugins and execute the CustomFunction in a separate function than the one that loads the plugins listed above.

I am building a form that will eventually list a group of functions on the left. If you drag a function onto the form, it will create a listbox and a label at the loction you dropped it to. If you drag a function into a listbox, it will add that function as a listbox item. I have this working kind of. The problem is that once I create a new listbox, I am no longer able to add items to the previous ones. Here is my code:
Public Class Form1
Private MouseIsDown As Boolean = False
'rivate Functionlist As ListBox

The first list box contains the project name. Based on whatever is selected in the Projects list box, the 2nd list box is generated with Custodian names associated with that project.

What I'm trying to do is make a list of members in a read only textbox getting the data from two textboxes (first and last name) and a 'save' button. I've made a class named 'Deltaker' (Members in english) to store data and a list 'resultater' (eng: results) using the 'Deltaker' class. I'm trying to get user input from two textboxes 'tbxFornavn' and 'tbxEtternavn' and I use my class' public function 'Navn' to display it in the textbox 'tbxHistory'.

I'm trying to get user input from two textboxes 'tbxFornavn' and 'tbxEtternavn' and I use my class' public function 'Navn' to display it in the textbox 'tbxHistory'.
I've got a sub procedure to add the input to the list and clear the textboxes and enable another reset button.
So for the save button click event I run the sub procedure and I've written a for next loop to display the results from the list. The first name I enter is all good, but with the second name entry both the first and the second name gets listed as well as the first name that is already there. I thought about using the .clear function to clear the list after each input, but I also want to incorporate laptimes in the list and display the best time in a lable at the bottom of the form. Maybe also sort the list, so I need the data in the list to stay intact.
Public Class Form1
Dim resultater As New List(Of Deltaker)
Private Sub AddDeltaker()

I don't know if this is doable, maybe with Linq, but I have a List(Of MyType):
Public Class MyType
Property key As Char
Property description As String
End Class
And I want to create a Dictionary(Of Char, MyType) using the key field as the dictionary keys and the values in the List as the dictionary values, with something like:
New Dictionary(Of Char, MyType)(??)
Even if this is doable, internally it will loop through all the List items, I guess?

I've been searching about how to list and remove or create all list of the ports forwarded on the current machine. So I can allow my app to create a port to allow the "chat". Wondering how this is possible. I saw many samples on net, tested most of them and none worked properly. Is there a possible way to edit ports with visual basic 08 or 11?

Recently I have learned visual basic 2008 express edition and developed programs for data crunching and analysis. The VB 2008 express edition has microsoft visual studio 2008 v. 9.0.30729.1 SP and .NET Framework version 3.5 SP1. Now I want to create x-Y (date-Y value) graphs using the crunched data stored in an array list simulating a data base access. I download and installed the "Microsoft Chart Control for .NET Framework " and try to learn to use it within the VB 2008 express edition using the tutorial. It seems that the chart control did not get installed?
1. Do I need at VB 2008 professional to allow using the chart control?
2. Why after installing chart control, there is no change on the items under the NET components within the Toolbox>ChooseItem>.
3. How do I get to use the chart control under VB 2008 express edition.
4. Any code available to generate versatile graphics without using the chart control? Because the chart control has tons of classes already it seems the best is to just use the existing and downloadable chart control?

I am trying to create a list of a generic type in vb.net 2.0 framework.
This is the generic type definition:
Public Class GenericParamMap(Of T)
Public Sub New(ByVal pParamName As String, ByVal pPropValue As T)
mParamName = pParamName
[Code]....
The compiler does not allow a "T" in the method's parameter because it's not defined, but I'm not sure how or where to define it. I thought it was okay to have a generic method definition.

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?

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!
