Adding From A Text Box To A List Box With A Button
Jul 6, 2009
I am trying to add things from a text box to a list box. I am running vb.net on visual studio 2005. At the moment, i have a list box, a text box and two buttons one for adding what is typed into the text box and one for deleting what ever is selected in the list box. i understand that for the adding from the text box to the list box i use the button1_click and need to define the entry as a variable but how do i move it accross to the list box? and also how would i delete the items in the list? the code is as follows: cmdAddZp_click is the add button, Zp is the text in the text box called txtnewZp and the list box is lstZp.
Public Class Form1
Private Sub cmdAddZp_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdAddZp.Click
Dim Zp As Integer = txtnewZp.Text

I started working on a product list with an array of products, these products are in a list view. You click the item and it is added to another list view and removed from the one it is curently in. I had it suggested to me and it sounded neater. I had no problems tinkering with codes and getting it opperating properly. But, What I am having trouble with is putting a cost to the product.
The idea is that the user would select products from the list and then they will be totalled together which is why it is important to be able to get the cost in there but not actually visable.Athiest advised me of a method used in combo boxes, because i was originally working with combo boxes. So I tried using that for my needs in a list view. Turns out to be a little more awkward than I thought. I get an error while trieing to add the item to my list box because I havent "declared" it.

i'm adding an text to my RichTextBox by using a button. what i need to do is to add the text and Focus the cursor at the end of the text in the RichTextBox.
for example, i use this code:
richRationale.Text &= Environment.NewLine & GV.index.ToString() + ". "
richRationale.Focus()
but the second command will focus the cursor at the beginning of the RichTextBox.

I'm writing a database program that will take various information from the user via text boxes, then save them as a *.txt file. I've already figured out the majority of that business. However, I'm having trouble programming a ListBox.
The ListBox needs to accept three pieces of information from 3 Text Boxes, then concantenate them when a button labeled 'Add' is pressed and scoot them to the ListBox (lstshowresults) while clearing the three boxes at the same time.

I 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?

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)

I dynamically create buttons on a form and use the button text as ids so that I can pass that to an SQL query to pull saved data about that button when necessary, but I also use an image over buttons that have information saved about them. What I need to know is how do I keep the text on the button from appearing when there is an image assigned to that button? By default vb.net shows both the text and the image and no TextImageRelation values allow for the image to take precedence. I tried changing the text color to transparent, but the outline of the text is still visible through the image. Is there anyway to keep the text value as it is but just show the image on the button?

I have to create a form that I enter the price of gas each month over a year. I enter the price in a text box and click the enter button to send the price to a list box immediatley and use an array. I have the following code but I don't think it's working with the array correctly as it will let me enter the information but doesn't stop letting me enter after the 12 prices. I am really having a hard time trying to figure out how to set up this input for an array and make it all work.

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 a program where i let the user dynamically add DataGridViews to the interface, those are also added to a list for easy management. All of the DataGridViews have their own datasources. I am using a Databinding source to get different DataGridViewTextBoxColumns to add.
The problem is the following: When the user adds the first table the following code runs:
dataGridList(dataGridList.Count -1).Clear()
dataGridList(dataGridList.Count -1).Add(NameDataGridViewTextBoxColumn)
No problem there and the right data is displayed, but when the user adds the second table i get an exception thrown:
"Provided column already belongs to the datagrid view"
I think this is strange since i access different DataGridView's right?
The point of all of this is to be able to view different columns in all the DataGridViews depending on the users choices.

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.

Ok so I have an array and wish to add the variables of the array to separate lines of the list box. I came across this which in some ways worked but also didn't. The second thing mentioned on the page was to us:
ListBox1.DataSource = Form2.Title This works the first time you run it but if you try to run it again nothing happens. So using the above or something else how can I get it to update the list box? Another thing I tried was to use the DataSource method but instead to clear the list box first, but that turned up an error

If I'm trying to output to a listbox, what is the easiest way I can enter a string and then a variable on the same line? I'm trying to use listbox1.Items.Add(...). Obviously outputting a string is no problem and outputting a variable is no problem, but I want to add a string and then a variable after the string. For instance:
name = "Joe Smith"
listbox1.Items.Add("Name: ", name) [or something like this]
[Output] Name: Joe Smith
