Adding Item To Listbox With Enter Keypress
Feb 10, 2009
I have been out of VB since VB 6, but am back into it to write a basic app. I have created a listbox and am able to add data to it from a textbox via a command button. However, I want to give the user the option to simply press the enter key after they have entered the info the textbox, instead of clicking on the command button. I tried calling the function the command button is using from the "ENTER" event on the textbox, but all that does is execute the function when I click on the textbox? I'm sure this is very simple. What am I missing?

For the last couple of days I been trying to add items to a listbox from another class within a system.timer.
They just don't appear in the listbox. I don't get any errors. The items just don't get added :S.
I have:
Form.vb
make object of Control
Control.vb
Here I have a system.timer
In the Timer_Elapsed method I do this: form.listbox1.items.add("hello")
But it just doesn't work... When I add a new item to the listbox1 from the constructor or another method that has nothing to do with the timer it works...

How would one go about checking a listbox's items for duplicates? Basically I need to write a program that displays the teams from a text file provided by my instructor, in alphabetical order. I can do that, but what I can't figure out is how to prevent the For loop from adding a duplicate team. What I'm envisioning is:
If teams(i).name is not in lstTeams.Items Then
lstTeams.Items.Add(teams(i).name)
End If
I have a program that compiles and works so far, except for the above problem and my alphabetical order (which I can probably figure out on my own:
Public Class danbrockteams
Structure team
Dim name As String
[Code]....
This works except that my listbox is filled with the team every player is in rather than just listing all possible teams. Not exactly looking for someone to just give me the answer, as I understand things best when figuring them out on my own, so I suppose a hint is what I'm really after.

I am trying to add to items to a combobox by using the "enter" key. It does work when I add the first item, but if I manually clear the box and add another items it does not get added to the list.
(1) I click in the combobox and type "hello" and press the "enter" key
(2) I click on the dropdown arrow and see that "hello" is in the list
(3) I select "hello" in the box and erase it, item is still in the list
(4) I type "goodbye" in the box and press the "enter" key
(5) "hello" is still in the list but "goodbye" is not
Here is the code:
Private Sub CopyrightCombo_Keypress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles CopyrightCombo.KeyPress
If e.KeyChar = Microsoft.VisualBasic.ChrW(Keys.Return) Then
[code].....
if I comment the if/end if line and type "hello" the items added to the combobox list are: "h", "he", "hel", "hell", "hello" wich makes sens since the add items is run on every keypress? I know that my commands for adding items is good, I know that my keypress event is handled properly but not when I specify using the "enter" key.

I am using the Event Handler below for the Enter Key Press Event, it is running when ever any of the keys is pressed. This is not so much a problem when the app. is running, unnecessary yes. It is giving me problems when ever I am Debugging using Breakpoints. How can I change the Handler so it only runs when the Enter Key is Pressed, doing away with the If statement?
Private Sub Form1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles Me.KeyPress
If e.KeyChar = Chr(Keys.Enter) Then
'Different code blocks will run here depending on what
'TextBox or Label is selected.
End If
End Sub

I'm building a Dialog in Winforms. It's got the two OK and Cancel buttons that are there when you create it, which is what I want. In this dialog I also have a TextBox and a Sub (coding in VB.NET) that handles its KeyPress event. I need stuff to happen when the 'Enter' key is pressed. Now, I've done such KeyPress handling times and times again. This situation, however, is different, because as soon as 'Enter' key is pressed, the dialog automatically assumes you're pressing the 'OK' button, returns a result and closes.
In both the Designer and the actual form when running the application, the OK button is highlight, which means is has some kind of a focus (for the lack of a better term) at all times. How can I disable this feature of a dialog? When I debug my code, pressing enter does not even get to the sub handling the KeyPress event. It simply closes the dialog and returns the result, therefore I can't really step through the code and see what happens behind the scenes. To restate the question, how can I disable this functionality?

move the focus to the next TextBox (don't worry about the Case 38, 58 etc too much I).
My Code:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'(Unrelated code here)
AddHandler Form1.KeyDown, AddressOf EnterkeyHandler 'Would like to understand this better

I have a Telerik Radgrid containing all the valid usernames and passwords that can be used to unlock functionnalities on my web page. The password is encrypted, so you have to click the row to decrypt and show the actual password. All usernames and passwords can be changed by an admin When the admin presses [ENTER] to submit the new username/password combination (instead of pressing the submit button), the new combination is actually submitted (which is fine).

I have two issues. The first is that I want to make a textbox scrolling similar to how credits scroll. I don't want it to move on the form, just to scrolling the text down a line/pixel. I thought I could do it with the "Lines" element, but I'm not exactly sure how to execute it.
The other problem is with my flash screen. Right now I have it set so when a button is click, it goes onto the main form. I don't want to use the button but rather have it so if Enter is pressed at any time, it'll go to the main form. All the solutions I've tried to use involve the "e.Keycode" code, but for some reason its unavailable.

I have a keyboard handler for my combobox1:
Private sub Combobox1_Keydown(....yaddda) handles combobox1.keydown
if e.keycode = keys.enter then
msgbox(combobox1.text)
end if
end sub
this always displays an empty message box,I need the value of the combo box before the enter was pressed, apparently the enter key empties the combobox1.text.

How someone would select an item from a list box and click a button and have that item go into another listbox with it's price? I seem to be stuck on this part.
Here's my code:
I want to select the first option from the first listbox and I want to put it into another listbox along with the price of that item on the same line in the listbox. I can't seem to figure out how to that.

I have 2 listboxes on my form.Listbox 1 - populated with "available" field namesListbox 2 - populated with "selected" field names.There cannot be the same field name in both listboxes - it's either one of the other.The logic I was going to apply was to populate Listbox 1 with every field name ... and then as I populated Listbox with the field names which the user has already selected, remove the corresponding item from Listbox 1.
