I want to have a PageUp Hotkey for the next page browsing and PageDown Hotkey for previous browsing.

XML Comments <list> Not Displaying In IntelliSense?
Aug 26, 2009I am trying to get VB.NET XML Comments to work with IntelliSense, and maybe it doesn't work the way I think it does.
[code]...
This should, when you are typing in a function, display the "Get or sets the Patient Code" then below that, it should display a list of bulleted items with "Validation:" as the header? Maybe I am doing it wrong, but it doesn't seem to be working correctly.

View 4 RepliesInterface And Graphics :: Anchors In Custom Controls?
Oct 21, 2008I'm having some problems with custom controls and anchors today. I made a custom control containing a picture box and a vertical scroll bar. When I adjust the form the custom control outer area (the blank part) will adjust to the size of the form but the picture box and scroll bar do not. I have the picture box anchored to all sides and the vertical scroll bar anchored to the right side. They just will not adjust with the control when it is resized on the form.
View 4 RepliesInterface And Graphics :: Custom ListBox Control
Dec 8, 2009I'm trying to build a custom ListBox control as inspired by the 'Audi Infotainment System' on high-end Audi vehicles. The only difference is i would like to have a 'boundary' where when scrolling up/down moves the actual list up or down. Basically, i would like my list to act like a normal ListBox except i would like to show say one or two items above and below normally only visible items.
View 3 RepliesInterface And Graphics :: Custom Right-Click Menus?
Oct 29, 2008I'm trying to bring up a simple right-click menu on a listbox and I'm having little luck with it. I created a basic ContextMenuStrip named "ContextMenuStrip1" and I'm trying to call it in the ListBox's Mouse Click method:
Code:
Private Sub ListBox1_MouseClick(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles ListBox1.MouseClick
If (e.Button = Windows.Forms.MouseButtons.Right) Then
ContextMenuStrip1.Show(MousePosition)
End If
End Sub
So here's what it's actually doing. The right mouse button doesn't seem to activate MouseClick at all for this object. It is caught in MouseDown, but when I try to call this from that method, the ListBox Index doesn't change. How can I get a right-click to be called from the MouseClick (Not imperative) and how do I get the ListBox to change the index with a right-click?Also, the menu looks like one of Office's right-click menu that can have an image to the left of the text. When I don't have an image the text is about 50 pxls or so away from the left edge. This looks weird. Can I change that?

The intention is to convert an IList of custom objects to a string equivalent comprising each element in the Ilist.

Multithreading - Create Custom Objects/list Of Custom Objects In .NET?
Jan 24, 2010I need two seperate lists, which every item is Integer, String, Bitmap - and one which every item is Integer, String String. However I don't know how to do this, or even where to look - I've googled for custom objects and custom object lists. What I'm trying to do is this.Custom Object1 is Integer, String, Bitmap Custom Object2 is Integer, String, String
In one thread I'll be adding items to List1(Of Object1), and processing them, and adding the results to List2(Of Object2), however I need to be able from other threads to look at the list and say only give me the items where Integer = (my thread ID), is this possible? Any help, or even links to information that would be relevant to this request would be helpful?
Objects To Interface With The GUI Instead Of List(Of T)?
Mar 9, 2010I have started using BindingList(Of T) for my generic collections whenever I need the objects to interface with the GUI instead of List(Of T). This has worked well for me so far but a few of my collections are stored in Dictionary(Of TKey, TValue) and there doesn't appear to be a corresponding BindingDictionary(Of T).
Has anyone else come across the necessity to use this, and how did they achieve it? Should I implement this myself? (How?) or is there a better solution already available?

View 4 RepliesCount Different Objects In A List That All Share The Same Interface?
May 26, 2011I have an object (MyObj) that itself will hold a List of other objects of various types and I want to count them as they are added to MyObj.That's the simple explanation, anyways...I have an Interface (MyInterface) that all sub-objects agree to. MyObj has a List(Of MyInterface) property that all the sub-objects are added to. MyInterface will expose a property that lets me figure out what subtype each object is (the sub-objects do not inherit from MyObj at all).
But I want to count these sub-objects as they are added to the list, and I'm trying to find a good way to do it. I don't need to worry about decrementing the count, as I am going to mimic the behavior of String and just create a new instance of MyObj if it ever changes, so all my counts will start from 0. This'll hit the garbage collector a bit, but I think this will allow for simpler (and safer) code. The only sane way I can think of to count objects is a very large structure in MyObj that uses bytes to hold the count (I will never have more than 255 of any given sub-object in the list in MyObj). But, even using bytes, this structure will be about 100-200 bytes big in memory (I have that many sub-objects), and I anticipate having a fair amount of MyObj copies running around, too.
I'll also need a large Select Case to know which count property to increment when a new sub-object is added. This seems to be a bit ugly, though I've used this approach several times already.What I am wondering is, instead of counting each object as it is added to the list, is there some way to query the list and count only the objects of a specific type? I wouldn't need to store this anywhere, since it would be dynamic, like querying a database and asking for a count of a specific column or type of record.I suspect Linq can do this, but Linq is also quite slow. Are there other approaches? Perhaps a predicate of some kind?VB (I am not a C# guy):
From i in MyObj.MyList Group i by i.GetType into g Let c as Int32 = g.Count() And that's it so far. I am still googling, but I am getting way too many C# and SQL references.
Interface And Graphics :: Popup Selection From Dynamic List?
Aug 8, 2008Is the ContextMenu control strictly to offer choices when the user right-clicks some object, or can it be used to offer choices in general?
In my situation, when a user opens a certain type of file, I want to offer a selection of specific subfiles (line ranges) within said file as choices. The presence of subfiles and their number is variable, so this would be a dynamic situation. (No subfiles: use the whole file; three subfiles: present three choices ...)Would ContextMenu be appropriate, or should I offer a list box or combo box or frame of radio buttons instead?
Unable To Cast From List(of Object) To IList(of Interface)?
Apr 19, 2011I'm new to generics and am having some issues when using with interfaces.I'm developing with VS2008 - .NET 3.5 Ultimately, I'd like to create an interface that inherits the IList(Of T) interface and add a function definition to the derived interface that adds a new element of type T to the list and returns the index of the newly added item.

List Of New Custom Object?
Sep 2, 2010I created a simple (for now) custom object:
VB
Public Class Form1
Dim AllPartFiles As List(Of Part)
[code]....
As I search a folder for files, it returns FilePath as a string for each file in the folder, then assigns a new Part.FullFilePath to the current returned FilePath, then add the Part to AllPartFiles list. So I can retrieve each Part from AllPartFiles later. But everything I try doesnt work.I know below is wrong, but might show what Im trying to do:
VB
Dim Files() As String
Files = System.IO.Directory.GetFiles(RootFolder, "*.ipt")
Dim k As String

Create a New Part, change its values, and then add it to AllPartFiles list for later, then repeat?

Searching The Custom List?
Feb 12, 2010I want to use a System.Collections.Generic.List<Of T> and store custom objects in the list. I then want to filter the list by my own custom defined criteria and return a System.Collections.Generic.List<Of T> of all the objects in the list matching my search criteria. For searching in Java, you would create an object that implements the comparator interface. The object would then be passed as an argument to the list's sort method. Is there an equivalent VB way to do this BUT when searching for items in the list?I have looked at using delegate functions, but these pass EVERY item of the collection into the function, which is not efficient in any way.
