Difference Between 2 Arrays Declaration?
Jul 21, 2011The Param1 works but param2 failed when passing it to method with object array parameter
Dim param1() As Object = {5, 5}
'And
TextBox2.Text = "5,5"
Dim param2() As Object = TextBox2.Text.Split(","c)
RichTextBox2.Text = CType(InvokeDllMethod(bt, "kayTestDynamicAssembly.KayTestDLL", "Addup",
param1), String)
My main question is that does .NET treat those 2 declarations differently or maybe I am missing something?

.net - Difference Between Declaring And Constructing A Value Type Object?
Oct 2, 2009I've been working in .NET for some time now, but occasionally I still get confused by a disparity between the framework and my prior experience in C++.In .NET, all objects are either value types or reference types. Reference types are allocated on the heap while value types are allocated on the stack (in the current CLR implementation, anyway). I get that. However, at least in VB.NET, you can still define a constructor on a value type.

View 2 RepliesInitializing Object Variables - Difference Between Methods
Jan 20, 2009In VB.Net is there any difference between the following three ways of initializing object variables
Method 1
Dim commandObject As SqlCommand
commandObject = New SqlCommand("MadeUpCommand")
Method 2
Dim commandObject As SqlCommand = New SqlCommand("MadeUpCommand")
Method 3
Dim commandObject As New SqlCommand("MadeUpCommand")
Is one more efficient than the others, or are they effectively all the same?

Application.Settings VB 2005 - Save Arrays Using The Settings System Object
Jan 14, 2009I just wondered if you can or can't save arrays using the settings system object. There seems to be no way of entering it at designtime. It seems implied you cannot create new user settings.subobjects at runtime. I'm looking to find the easiest way to save a populated array of PictureBox's. If the only way is a self/custom made/managed .ini file then I need to know so i can start on that but I was hoping to use some of all this phaff in the new frameworks usefully.

MyApplication_Startup And Module Variable Declarations?
Dec 15, 2009It is my understanding that all modules are initialized and that all their variables are set up prior to MyApplication_Startup. I have code that has worked well for quite some time (XP and Vista).The Myapplication_Startup code references variables and code located in a Module.However, with Windows 7 this does not work.Anny reference to a module (Data, SUB or FUNCTION) throws a Type Initialization error at runtime. How can I correct this behavior in Windows 7?

Variable Declarations In VB 2008 Express
Apr 9, 2010Although I have been programming for many years, successfully, in many different languages, translating my large Word VBA application into VB 2008 Express is driving me crazy. While I understand the theory of OOP and have even been on object-oriented courses, it seems I can't declare my objects correctly and use them in my code. As far as I know, I'm not trying to do more than the "language" is capable of doing, but here goes.
I want to start with "aList" which would be a Collections.Generic.Dictionary(Of String, String) object. Then I want a "bList" which is also a a Collections.Generic.Dictionary object. I would like each bList item to have a few individual simple properties (like a Byte and a String) then an aList instance as well. The application then gets a bList key value from the user, "copies" the corresponding bList item values into a work area, and does the necessary processing using the various bList(aList) / aList(bList) item values from the work area. I say "copies" because I assume that part is simply going to be a pointer copy rather than a long copy of lots of strings. Note that I really don't want to start using arrays here, as the application makes alot of use of Word VBA Dictionaries and I'd like to keep it that way if I can. Incidentally, so far, I have all my global data declarations in a separate Class, not on any of the application's forms.

I want the module to execute first before anything else, and so I call module.main() from the MyApplication startup event. At about the point that program execution gets to the beginning of module-level declarations in the module, it also starts running though the class-level declarations in the thread classes, but long before the threads are declared or the threads are started in the module code. I can't figure out why it happens! Is there some way of supressing that until later (i.e when those classes are actually instantiated)?

VB6 Used Recordsetsor Arrays - .Net Framework In VB2010. Datasets, Dataviews. Tableadapters, Arrays. Enums ?
May 9, 2010In VB6 I load a recordset containg all of the records (6 fields per record)in a table into an XArray and then manipulate the records in the array and then write them back to the original table. The array issorted by the first field (1 to maybe 8000 or more) I need to find records in the array by an ID field and then move them (because of some external criteria that happens many times) from say number 400 to number 375. Then all of the other records between 375 and 399 were renumbered up 1 to fill the gaps left by the move.
The XArray worked well as it could find and also move to a next record easily to facilitate the revisions to each record quickly. Everything is done in VB6 in code and nothing visual needs to be shown to the user until say 2000 of these external changes are complete. What is the best, most efficient way to do this in the .Net framework in VB2010. Datasets, Dataviews. tableadapters, arrays. enums ?
