Copy And Merge 2 Arrays?
Mar 13, 2009
I have 2 arrays, I don't know their length...I wanna copy both arrays into 1 single array.So the length of output array will be sum of my 2 input arrays.I know I should use Array.Copy but don't know how, for my case, it won't merge the contents of 2 arrays into 1.I also used this but won't work:
Code:
ReDim OutputArray(InputArray1.Length + InputArray2.Length - 1)
Array.Copy(InputArray1, OutputArray, InputArray1.Length)
Array.Copy(InputArray2, OutputArray, InputArray2.Length)

I'm editing a vb.net app for a mate and part of the requirements are to copy merge fields from one word document to another. I can copy them across using document.content.text but they come out as text (should've figured this i guess). I think i've got them selected by:

I have 2 byte arrays. I want to merge these two byte array into 1 byte array.Usually, I just create a new byte array with length = byte array #1 + byte array #2. Then copy byte array #1 and #2 to the new byte array.do I have more efficient way to merge 2 byte array using VB.NET and .Net 4?

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

the statement Dim state(49) As String and maintain a list of certain states. The list of states should always be in alphabetical order and occupy consecutive elements of the array. The buttons in the program should give the user the following options: (a) Take the state specified by the user in a text box and insert it into its proper position in the array. If the state is already in the array, so report. (b) Take the state specified by the user in a text box and delete it from the array. If the state is not in the array, so report. (c) Display the states in the array. "
Private Sub states_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
state(0) = "Alabama"

I was wondering if anyone knows a built in method ( LINQ say or a LAMBDA expression or other way ) that you can compare2 arrays - collections that would be valid for an equivalent 3rd array - collection which is a combination of the 1st two.
As an example consider;

I have an application, written in C#, which needs some functionality from VB.NET (better said, something valid in CIL but not provided in C#).
So I have an executable and a library file.
Problem:
It has to be published in one file and may not be split to different assemblies!
But:
It's a WPF application, ILMerge will not work.
What could I do?Is it possible to generate (performant) IL on the fly?

I'm trying to create a program that will merge two data tables (one from a database on a network drive, the other is found in a database on the local machine). Each datatable is identical in structure, only (maybe) differs in content. The structure has a primary key, dateCreated, and dateLastEdited fields (plus other fields). I would like to merge down from the network to the local database. If the primary key does not exist on the local db but does on the network, copy from the network db to the local table. If it does exist, check the dateLastEdited column and copy the latest row to the local table.
How would i set up the code to do this? Any assistance would be great.

I'm trying to merge 2 files - a 'simple' string replace. 2 files - an ini-style data file that has <descriptor>=<value> with about 70 rows created by web-form and database, and a csv template file with 2500 rows that has 12 fields, but the values will either be in fields (4) and (5) OR (6) and (7). The data fields won't always be in the same order. I'm reading a line from the Template file, then looping through the data file looking for a descriptor match then replacing it with the value, but because they are in pairs per line, I have to loop twice; then loop to the next template file and so on. Then cleanup to remove the unused descriptors.
I have been unable to crack this for about a week. I wrote a VBScript version yesterday in about an hour and it worked flawlessly first time taking 2 seconds to produce the csv output file exactly as required.
Tried reading the data file and looping through the template, tried almost every combination of Using/End using; For/next, Do Until, Do while, etc. Used Streamreader, File.ReadAllLines, I've read msdn till I know it by heart, but no use. You name it, I've tried it. Must have missed something or it would work though.
You are my final hope. The problem part of the code is below...
BTW -
srXX = StreamReader
swXX = StreamWriter

I have a GUI that is running for a form, let's call it Class xWindow. It has finished processing data and is simply waiting for the user to press a button, i.e. the main thread has nothing to do. Just before it finished processing, it kicked started something that has a callback function which occurs in a new thread (e.g. a system timer or a Bonjour callback to say that a service has been found on a port). This callback occurs within the xWindow class.

I need to marge two datatable with condition. i table data come from local XML Database and another data come from remote sql data if any update made at remote datatable and then marge with local datatable. i wrote a code below :
Public Sub MargeTwoTable()
Dim SQL As String = ""
Dim RemoteTable As New DataTable
Dim LocalTable As DataTable
[code]....
as you see in my code data come from remote database which update date getter then local database . Both table are same and "ID" is primary key. I code is working well. But problem is that when data more then 1000 updated record so this function take too long in loops.
i write a code like : Dim mm() As DataRow = LocalTable.Select("ID = '" & RemoteTable.Rows(i).Item("ID") & "'"). for finding local datatable id row so when data is more then 1000 it take too long because localtable record more than 100000 records. So I need someone help to modify my code what the best way to write the code.

I need to marge two datatables with condition. I have a datatable where the data comes from a local XML Database and another datatable where the data comes from a remote SQL Server. If any update made in the remote datatable I need to update/merge with the local datatable. Here is what I have so far:
Public Sub MargeTwoTable()
Dim SQL As String = ""
Dim RemoteTable As New DataTable
Dim LocalTable As DataTable
[code]....
In this code data comes from the remote database which updates a date getter then the local database . Both tables have "ID" as the primary key. The code is working well, but the problem is that when more than 1000 records are updated this function takes too long using loops.
