ListBox And Keyboard Control
Mar 27, 2009
I have a ListBox Control containing 5 items. This control displays the current condition and allows the condition to change. The ListBox.SelectedIndex is calculated from the current condition (normally item 2 in the list) and displayed. If the user requires to change this condition the Keyboard Up/Down would be used for navigation (The App is very keyboard intensive), however if the ListBox.SelectedIndex is set at 2 and the keyboard down arrow is pressed the selected item displayed changes to 0 not 3 as required. Is there a way to synchronise the keyboard control with the current selected index?

I'm developing a program in WPF (VB) that relies on keyboard navigation only.In my program, I have a listbox that displays up to 20000 items.What I want is that when the listbox has keyboard focus, and I move to the bottom item that is visible (using ArrowDown), I want the focus to move to the next item outside the listbox. I'm using PgUp and PgDown to scroll the listbox contents, and text search to jump to items.Is there a way to detect if the focused/selected item is the last/first visible item in the listbox?If so, I could just use:
ListBox1.MoveFocus(New TraversalRequest(FocusNavigationDirection.Down))

I have found a program called ledsdriver( http:slicksolution...edsdriver.shtml ). i can control the serial ports on your pc but also the keyboards lights (caps lock,num lock and scroll lock). The good thing is if i connect 2 keyboards i can chose which one i want to change the lights.I want to make one that could control the keyboard lights but only on one keyboard. I wold like to make my own because i could customize it(that one isn't open-source). How can i do that?

I used the following code:

I use VB in VS2010..My form has a textbox..I can control the keyboard entry by using the SuppressKeyPress method..However this does not work for the Menu key - I think it's the menu key - the one that looks like a combo with an arrow.This produces a large drop-down menu which I don't want.On checking various forums it appears that the following code should work..[code]

This isn't really a VB specific question. It's .Net in general... if you have ideas in another .Net language, let me know... I know most of the .Net languages (I don't know that foxtrot or what not weird ones). Furthermore this isn't a 'I don't know the method on some class I should be using' kind of question, it's a design/problem solving kind of question.I'd like to know how you'd approach the problem with in the boundaries set.

I have created a virtual keyboard like the "Windows onscreen keyboard". So, I have used the method sendkeys.But if I click on the button, it doesn't write nothing.
I think I have a problem with the FOCUS.As you can see, the "Windows onscreen keyboard" is always on top.This doesn't happen to my form. How can I do?

I am using Visual Basic 2008 Express Edition and I am trying to set a listbox so it starts to scroll when it hits the middle point of what is viewable on my list. I also want to set it so the list is always visable so you when you reach the bottom of the list you can scroll down to the bottom but if you scroll back up once it reaches that middle point it will start to scroll up again.

I have a listbox control (in a WinForms application) that lists a bunch of statistics about records selected from a database.
Is there an easy way using VB .NET to take the contents of this listbox and send it all to the printer, or at least have one of those standard windows print dialogs come up, prompting the user for which printer to send the listbox contents to? Doesn't have to be fancy or anything.

I thought I'd embark on a little project, just making a registry editor as the one on WinXP is a little.. Plain and boring, so I thought I'd make my own.I'm having no problems loading the registry into my form, although I'm having difficulty loading the data into a ListBox control.. I can set parents, for example Local MachineDynamic DataPerformance Data..This is no trouble. I know it's possible, but I don't know how to create the following structure [code]Basically, I don't know how to add a child node to the ListBox control.

I'm writing an application; I have an Advanced Tree control and a ListBox control. When I populate the ListBox programmatically, using a function that returns a ListBoxItem, it adds the field fine, but displaying incorrectly; it doesn't just add say "My item," it adds "ListViewItem: {My item}"
When I add the item using just a string, it adds fine but I need to use the return function to set the tag data and such, but when I use that function, it adds the above which is really annoying.

I'm using a list box control and I've specified an item height of 25 and DrawMode of OwnerDrawFixed as well as coded up all the necessary ListBox_DrawItem code to get this to work. My problem is when it displays my list all the items are top justified in the list. I want them to be centered and right justified so when the are selected they are in the center of the highlighted box, not at the top of it. Does anyone know how to do this?

I have the following sub:Private Sub AmIintheListBox1(ByVal datatoenter As String)'Note.- ListboxItemsCount is a variable in the listbox1 change event
[Code]...
I do not know how to do the search of the datatoenter in a listbox with more then one item. If the item is already in the listbox then exit otherwise add it to the listbox.Threaddisplay adds the data to the listbox which I can do when there is no item yet.

Using ASP.NET and VB.NET code behind, I have the following code:
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim I As Integer = 0
For I = 0 To 10
ListBox1.Items.Add(I)
ListBox1.DataBind()
System.Threading.Thread.Sleep(300)
Next
End Sub
The intended output of the code is to update the listbox1 control at each iteration, but what really happens is it updates the listbox1 control after the entire loop finishes..Is there a way to update the listbox1 control as its intended by the code logic?

I need a 2-listbox mover/selection type control such as the example here: [URL] For over a week now I've searched countless forums and done myriads of googles. All I've been able to find is C++ or ASP based stuff. I really would like this to be VB.net, but at this point, I'd even settle for C#.
I've taken a shot at developing it myself, but am too new to the .Net world to really get anywhere with it other than being completely overwhelmed and frustrated. I've even looked at some 3rd party custom control webistes, and am even willing to spend a few bucks for this thing, if I could find one that suits my needs.
