VS 2008 Intellisense, Indexed Properties?
Sep 26, 2010
I've wondered this for a while, when I hover over an object's properties when the program is paused (from a breakpoint) I can see the values of each property but when it comes to a collection it wont list the objects in the collection unless I specify an index, how do I specify an index?Basically I have a form with a ToolStrip that has 12 items in it, I would like to see what the 12th item is but can't because it's an indexed property.

1) How is the Name property hidden for controls for the Properties window yet it is shown in Intellisense?
2) For a System.Windows.Form.SplitterPanel the Name property is not shown in either but you can still Get or Set it.

I came across a DbParameterCollection object, which should have an "Item" property inherited from IList, but IntelliSense does not show this object has the Item property.

When you type sender. IntelliSense lists 5 methods and yet if you type sender.Left or sender.top these will work. Why don't these properties show up as available for use via IntelliSense.

I am writing my first class-library in VB.NET. My idea is to distribute this library so others may use it in their applications.However, perhaps due to my lack of experience in writing and structuring the library and the classes therein, I noted that the methods/properties are ALL being shown in the IntelliSense of Visual Studio.
The thing is that many of them are only used within the library itself and should NOT be used by the developers (could create a disaster) when they incorporate my library in their application - only a few should be visibile i.e. the ones which are needed by the developer.Thus, my question is: is there a way to hide certain methods/properties of my library from Visual Studio's IntelliSense? Maybe something similar to REM?
EDIT: as mentioned - this is my first library and I now understand that my question could be intepreted in two ways:
1) how to hide something from IntelliSense
2) how to prevent a developer from using and calling certain methods/properties
Of course, the end-result that I want is that the developer is not able to access AT ALL certain methods/properties i.e. No. 2 above.

I am primarily a C# developer; however, I am currently working on a project for a client who preferred VB.net. I have managed to switch over fairly well, with one frustrating exception. When editing a C# file in Visual Studio pressing enter will select an item out of the IntelliSense window and keep the cursor at the end of the selected statement.
However, when editing a VB file, pressing enter selects the item out the IntelliSense popup AND moves the cursor to the next line. I realize that this is a small thing, but it drives me crazy, because it makes it really hard to switch between C# and VB projects.
I have searched for everything I can think of in Google and found nothing. Does anyone know of a way to change the IntelliSense selection behavior?

I don't know if it's possible, but i want to change some of the defaults intellisenses. For example when i write try and press enter, the IDE puts the catch ex as exception and the end try, but i want that the finally word it's added too.

I've found the ability to make meaningful Intellisense-enabled comments on my functions and sub routines absolutely priceless.
I'm wondering if I can do the same when an Enum is defined. I'd like for each Enum highlighted in the drop list to have some information associated with it. Can that be done?

I have a TableAdapter I created in the DataSet designer. It contains joined tables and I set it up to automatically generate Insert/Update/Delete commands. I understand that I have to write my own UpdateCommand. I did so, in the DataSet Designer, for this particular TableAdapter.
The issue is that the Update Method is not showing up via IntelliSense, when I attempt to write code like this:
vb.net Dim x as Integer = Me.DPTableAdapter.Update(), IntelliSense does not show the Update Method with the parameters I set up.I created the same exact method with another TableAdapter, in the same manner, and it worked just fine.
I also call EndEdit on the BindingSource, I just did not put it in this post.

If I override a member (e.g AutoSize in the Button Class), then the intellisense no longer appears in the editor, forcing me to re-decorate the property. Is there an option somewhere that I need to check? ETA: Here's a code sample:

The intellisense explaining the AutoSize property doesn't appear.

I'm almost sure that I've seen this somewhere, but I can't find it anymore. Or maybe I'm imagining it, which would'nt be strange either.
When creating a sub or function and adding parameters used when calling it.
-Is it possible to list the parameters that I can enter when using it somewhere in my code?
E.g.
Public Sub MessageMain(ByVal Message As String, ByVal MessageType As String (List of possible values for MessageType)) Same for example as when you have boolean values in a sub/function. As soon as you use that somewhere in your code intellisense will present you with True/False to select.
I'd like the same for parameters in subs or functions I create and calling them from somewhere in my code. Saves me the trouble of remembering which options are available for those parameters.

I have a listbox and I want to loop through each of the items to see if the string im looking for is inside. I know I could do .contains but that wouldnt look at substrings. The code im using looks like this:
While tempInt > Listbox.items.count then
if searchString.contains(listbox(tempInt)) then
end if
tempInt+=1
end while
Everything in the loop is fine but VB gives an error on the listbox(tempInt) part. The error is "class windows.forms.listbox cannot be indexed because it has no default value". get around the default value crap? I tried putting in a blank string but no change.

Public Sub LoadFromFile()
Dim sr As New StreamReader("CoverageArea.dat")
Dim strAreaLine As String[code].....
I have a question about that strAreaInfo()...I left the () with no number in it so that it wouldn't have a set # of values, and then I tried to give it 3 values, but I get the error in the title. Am I doing something wrong when I declare it?

I'm working on a small game that is based on a map of grid squares.I have a class (clsGrid) that stores a few properties for each grid square.The grid square objects are organized into a list(of clsGrid).A loop and stream reader are successfully reading properties from a text file, putting the properties into grid objects, and adding the grid objects to a my list of grids. When retrieving a grid from the list of grids, I'm getting unusual results. Regardless of the index I give the list, I always seem to get the last indexed grid in the list.The debugger seems to suggest that the right numbers are being read into the stream reader and they are being added to gridHolder. However, the message box at the end will always show me the LAST grid.id, regardless of the index I give it.

I have a form with a lot of PictureBoxes. I created an array of these by name, but when I index the array I cant assign an image to the indexed item. In fact all the indexes appear to be nothing. Is there a way to create an array of controls and access them from the array?

I'd like to create a Dictionary that is indexed by Strings: Dictionary(of String, ...). I'd like the Type after the comma to be an Array of MyObject's. If all I do is the following:
Dim D as new Dictionary(of String, Array)
I feel like I'm missing out on some performance very time I access a member:
Dim Object1 as MyObject = MyDictionary("Key1")(4)
Doesn't it have to perform some type of lookup to figure out what type of object the array is holding every time I access it in this manner?

I would like to create a list of integers. The list will be items that I need to index by a key (string) or an index, which I set. For example I have items 1, 2, and 5. I would like to call Array(5) = 1. Where the the 5 is indexing a particular item 5, not the 5th item in the array. Using Array("5") = 1 could work as well. I tried using a List, but the only index is the ordered element of the list. I tried a Collection, but I kept getting errors that the items of the Collection are read only. How can I do this?
To be more specific, I have a simple game application which has a Player class. Each Player is trying to collect hits of say 3 fields {1,2,5}. I need to store how many times a player hits each of the 3 fields. So, I would like to read and write using logic like player(1).field(5) = 5. I want to add an object to the Player class which stores the number of times each of the 3 fields has been hit.

In Visual Basic 6:
[var = ] Point(X,Y) would retrieve the Color in Long from an Individual Point on a Form or Picture Box.
Components(TextBox, etc) were indexable into an array under one name.
Is there any manner to do any of this in Visual Basic Express? (I have the 2005 Edition.)

When writing to an Access file with one of the fields indexed (NO dupes allowed), I am getting the following message in the Immediate Window "A first chance exception of type 'System.Data.OleDb.OleDbException' occurred in System.Data.dll", when I enter a dupe.
I have put in a TRY, CATCH to catch the error and display a msgbox with the error. Is this message in the IMMEDIATE WINDOW just a warning message (generated by access), or is there something wrong with my actual program? My program does not actually crash, it seems to be working great.
