I have two strings arrays
Dim sir1() As String = "m1-m2","m1-m3"
Dim sir2() As String = "1-0","0-0"
What I want is this output:
m1-m2 1-0
m1-m3 0-0
Which is the fast method to concatenate them?
I tried
Dim sir3() As String
sir3=sir1&sir2 but with no result

Say I have a List(Of Tag) with Tag being an object. One member of Tag, Tag.Description, is a string, and I want to make a comma-separated concatenation of the Description members.Is there an easier way to do this than to read the Description members into a List(Of String) and then use the Join function?

I have a long string that has been divided into lots of smaller Strings using the following pattern:
Public Class Test
Public Prefix_1 as String = "1 to 100 bytes"
Public Prefix_2 as String = "101 to 200 bytes"
[code]....
And this Test class has been compiled as class library project (i.e. a .dll file) and saved to C:Test.dll note that I have no prior knowledge of how many Prefix_ string existed in the dll file.My question is: How to retrieve all strings that start with Prefix_ via reflection and concatenate it ascending-ly (i.e. Prefix_1 & Prefix_2 ... ) into a single string?
Suppose I have the following data
Key ID Data
A 1 Hello
A 2 World
B 2 Bar
B 1 Foo
I am looking to produce the result
A HelloWorld
B FooBar
I am struggling to get the syntax quite right - I was trying to use Aggregate, but I wasn't sure if I could (or should) use SelectMany
Dim data = result.Rows.
GroupBy(Function(r) r.Key).
Select(Function(g) g.OrderBy(Function(s) s.ID)).

Is there a way to use [string].Join to concatenate html stings including spaces? I want to join html strings with a special character so I can pass them as an array to javascript from the code behind.
Dim Array(100)

String
ArrayString = [String].Join(",", Array)
This works great if each item in Array is one word only, but what if each item in Array contains spaces?

I am toiling with the best way of doing this. So far, I am not having much luck. I have used arrays quite successfully in Java, but I am not sure that this is the best way to go here. I would have to get how many lines there are and read each line. Make the changes, and then go on to the next line. I think scanning the document line by line using a loop is the best way. However, I am not sure.
I was wondering if, perhaps, someone could help me understand why the following code gives me a garbled result? Instead of displaying as it should I get '.Net 2.0 Application Development Foundation Framework Microsoft'.[code]

I'm making a random sentence generator that takes subjects, predicates, etc. from user input, stores them, and then randomly chooses one value from each category and prints it in a textbox. Or at least, that's how it's supposed to work. But I just can't seem to get the text to print in the textbox. Everything compiles fine, but when I click generate, Windows gives an error.

The problem I'm having is I'm not sure how to go about getting the correct ones into the correct arrays. The data is scattered throughout the file. They are not on the same line and some are multiple on a line as well as blank lines, however they are in pairs. As they are not separated by commas or just white space is there a way to load the first string to the first array and every other string to the second array

View 10 RepliesIn 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

Can somebody give me a idea on how to accomplish the following/I need to take the number (which is an integer from a simple math function) and the letter A and create something like "A10" or "A45" or "A123". Can someone please give me a tip on how to accomplish this?The program creates the integer by using the value of a drop down box and a reference number of 9. The maximum value will be 109 and the minimum is 10. It needs to be combined with the letter A, which does not change.
