The 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?
if I created a new object like this Dim sqlconn As New SqlClient.SqlConnection(cs)
and Dim sqlconn = New SqlClient.SqlConnection(cs) Whats the difference?

In 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 ?

I have a VB.net console app and I am opening a function in a dll written in fortran. I am passing 3 arrays through the function by reference. When they come back out the otherside they ahve all tunred to arrays of only one element And that element is 0.I read on the internet somewhere that when doing this kind of thing it is a good idea to only pass the first element of the array into the function.I tried changing my function declaration to accepting single elements rather than single dimensional arrays, and now the arrays are the same length before and after the function call, but they don't seem to be changing at all, so i'm not sure that this is working

I've built a really good narrator, for totally blind people so that they can interface and use the computer in a substantial way. The innovation is a static mouse that controls category input, rather than free mouse movement, and the middle wheel selects items of that category.

I am creating a kind of a "naive" search engine.What I have done is distributed words in files where each file corresponds to the starting letter of the words (i.e. if its English, then 26 files are there)Then when the search system loads I am loading all the words in hash tables (26 hash tables corresponding to 26 alpha-characters) for which I am using an array of structures.The problem is after declaring the variables in a Form load subroutine, the variables are not able to use those values in other subroutines..How do I properly declare them so their values persist?

Should I maybe always specify a value at declaration, even if it's Nothing, and just override that value in the constructor(s) as needed? Or is it situation specific? If so, a really quick rundown of which situations might warrant which treatment would be nice.
