VS 2008 WinForms Label Control Handle Focus?
Jan 30, 2011There is a panel which contains 2 components: a label and a TreeView. The hierarchy, obviously, looks like this:panel1 // handles Enter event
- label1
- treeView1
I need to do some UI updates when user starts interacting with any of these 3 controls. My attempted strategy was to catch the Enter event of the panel, which would fire when user clicks a label, or TreeView. This way, I can write only one (1) event handler instead of several. While it worked for the TreeView, it didn't work for the label. When I click the label, I don't get the Enter event on the panel. Whats different about the label control? I could handle the Click event of the label. At the same time, I wonder what the other solutions might be.
Simple Databinding - Handle Bound Field/property Change - Winforms / .Net?
Oct 19, 2009I have a custom control with a bindable property:-
Private _Value As Object
<Bindable(True), ... > _
Public Property Value() As Object
Get
[code]....
Also, here, I'm adding a handler to the DataBindings.CollectionChanged event.This is the second place that I retrieve the type:-
Private Sub DataBindings_CollectionChanged(ByVal sender As Object, ByVal e As System.ComponentModel.CollectionChangeEventArgs)
If e.Action = CollectionChangeAction.Add Then
Dim b As Binding = DirectCast(e.Element, Binding)
[code]....
I need the first place, because the BindingContextChanged event is not fired until some time after InitializeComponent.The second place is needed if the binding field is programatically changed.Am I handling the correct events here, or is there a cleaner way to do it?
Note: My GetValueType method uses the CurrencyManager.GetItemProperties....etc, to retrieve the type.

Adding An Empty Row To A Databound Listbox Using Linq2SQL And Winforms?
Sep 28, 2011what is the most robust method for adding a empty row (to select "nothing") to a ListBox?
Dim List = Enumerable.Repeat(New TABLE With {.Text = "", .ID = -1}, 1).AsQueryable().Union(From t In mainctx.TABLEs)
ddlMangelKategorie.DisplayMember = "Text"
ddlMangelKategorie.ValueMember = "ID"
ddlMangelKategorie.DataSource = List.ToList
But this has some drawbacks:wordy must explicit write the Type (TABLE in this case), so i cant wrap this in a function have not found an solution, which works with anonymous types I.e. if I add a From t In mainctx.TABLEs Select Text=col1, id=col2 to the query, this method does not work anymore.

View 3 RepliesJoystick Handle - Use Only The Handle Of The Component?
Mar 23, 2009I wrote an application to handle a joystick with directinput. It works fine if it uses the handle of the main window but it doesnt happen the same if the handle is the one of the component that contains the joystick's operation.
I mean:
main form handle: 15
component handle (which is inside the window and the joystick needs the focus of this component to work): 25
It always work if the handle i initilizate the device is the main form (15).How can i use only the handle of the component?
IDE :: Set Project Default For Winforms Projects S/ Default Modifier For Controls Added To Winforms Is Private
May 28, 2010Is it possible to set a project default for VB.NET winforms projects so that the default Modifier for controls added to winforms is Private (not Friend)?I know there's a "modifiers" property in the properties window so I can set it for each individual control however I would like to change the project so from now on myself and other developers have to specifically decide to change from friend to private. (Which I would strongly discourage them from doing).I believe there is no way of doing this, but on another forum a while ago someone mentioned it would be possible with an add-in (but didn't name the add-in or where to get it).
View 1 RepliesListBox PreferredHeight - Make ListBox Calculate Correct Integral Height Before ListBox Is Made Visible
Nov 19, 2009If I set a ListBox.Height = ListBox.PreferredHeight when the control is hidden and IntegralHeight = True, then set it visible:
a) Actual Height reduces by typically 3-5 pixels after redraw (but not 1 pixel per item).
b) PreferredHeight does not not appear to give the correct integral of item heights.
Is there a way to make ListBox calculate the correct integral Height before the ListBox is made visible, so it can be correctly pre-positioned from bottom edge?
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
ListBox1.Visible = False

Listbox Items Colour - Two Types Of Items Populating In A Listbox (checked Listbox)
Apr 28, 2009I am using VB.NET (version 2008). I have two types of items populating in a listbox (checked listbox). For example: lets say one is type "A" and other is "Type B". Their names maybe same so if the user sees those items in listbox then he won;t be able to determine their type until he click on them and checks out its properties. I wanted that I add each item to listbox and colour them so that blue for example means type "A" is there and red means the other. So this way I will be able to know at a glance that how many item of what type is present. I guess it may not be possible to do that in a standard checkedlistbox. I am also using component factory's krypton controls which enhance the gui of an application. But I dunno if I can progress using that.
View 5 RepliesInterface And Graphics :: Listbox Event - Scrollbar That Comes With ListBox Is Too Small For Touch Screens
Jan 6, 2011The scrollbar that comes with the ListBox is too small for touch screens, so I use my own scrollbar instead. But when you do this on various forms you end up repeating a lot of code. So my solution was to create a custom scollbar that has a property I can set to the control I want it to be a scrollbar for. In vb6, I can use the withevents keyword to get access to the control's events so that all the scrollbar related code can be in the custom scrollbar object I created, except...I had to create a refresh method for the consuming code to use to let the scrollbar know when the number of items changes. The scrollbar doesn't need to be told how many items there are because it has access to the control, but for a listbox there is no event to tie into when an item is added/removed so not 100% of the scrollbar related code could be encapsulated.

[2008] Copying From One Listbox To Another And Keeping The Paths Of The Files In The Listbox's
Jan 26, 2009I am having problems with copying from one listbox to another and keeping the paths of the files in the listbox's. At the moment i have two listbox's, listbox1 shows the list of files without the directory paths showing. Listbox2 is used to add items from listbox1 which work ok but what i need is to be able to preserve the directory paths to each file. how to do this and have searched high and low for a solution without any luck.
I have worked out one way of doing it but i think there is a better way of doing it as the reverse does not seem to work. So basicly i want listbox1 to list the files without the paths and pass it on to listbox2 so that the files can be copied to temp directory as they are being add to listbox2.
Below is my
