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

I have been summoned with the task of taking a tab delimited file and converting that file so it can be read by a third-party program. I am trying to think of the best way to do this, but I am having a hard time. Here is a view of the raw data that must be altered:

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 am in need of encrypting a byte array, but my encryption method that I found strictly deals with strings.
Here are the two pieces of code that I am dealing with.:
The byte array (the bytes that need to be sent encrypted)
Code:
Dim outStream As Byte() = System.Text.Encoding.ASCII.GetBytes(TextBox2.Text + "$")
serverStream.Write(outStream, 0, outStream.Length)
serverStream.Flush()

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.
Since I have barely any time, for it is a project at an enrichment course that ends in 2 days, I've been trying everything I could without taking too long.[code]...
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 3 RepliesI was getting weird results when doing multiple splits on a string, so I decided to make a simple test to figure out what was going ontestString "1234567891011121314151617181920"If I wanted to get whats between 10 to 20 in Javascript I would do this:var results = testString.split("10")[1].split("20")[0]Which would return 111213141516171819However when I do this in VB I get 111Split(testString,"10")(1).Split("20")(0)It seems the 2nd split is only recognizing the first character no matter what I put.

working with arrays is not something I am too good at,Currently I have a form with 2 text boxes and a single button. I have two arrays, one populated with user names, the other populated with password. The user names and passwords match up in position in each array. I am thinking I might need to create a multidementional array of these two arrays.
[Code]...
If I do this however, any user name gets matched to any password, pending both exist. I would like to be able to compare the user name and password of a single user. Right now the user names and passwords are stored in separate arrays. Should I merge the two into a single array? If so how? And if so how do I go about matching the text box entries to the array(s) and making sure that the user name and password matches?
How I can make control arrays like vb6? I need for example,
button(1).backcolor=...
button(2). backcolor=... etc.
And I wanna work with it's indexes.
This is my first time posting here although I have been lurking for quite some time. I'm stuck with a problem I have seen before and never solved: I have a long list (~23,000) of alphanumeric strings that I'm reading into a List(of String) from a text file, and then sorting. When I iterate through the list after sorting, it appears to be correctly sorted EXCEPT that the element that was originally at the beginning of the list is now at the end (and it should be somewhere in the middle after the sort)Here is a sample input:
PRE1-PRE2_00015648
PRE1-PRE2_00015649
PRE1-PRE2_00015650

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 am working on a UDP Client/Server, and currently i have them sending back and forth strings, which i convert to bytes, and then open the bytes to read. I want to now send an Object instead of those strings, which includes multiple unsigned integers and strings.
View 39 RepliesI have a list of strings. For each string in that list, I want to prepend another string. I wrote a method to do it, but I was wondering if there was something already in .NET I could use to do this. It seems like something that could be built in, but I was not able to find anything.
Here is the method I wrote:
Private Function PrependToAllInList(ByRef inputList As List(Of String), ByRef prependString As String) As List(Of String)
Dim returnList As List(Of String) = New List(Of String)
For Each inputString As String In inputList
returnList.Add(String.Format("{0}{1}", prependString, inputString))

It works, but I would rather use built in functions whenever possible.
I'm migrating from VB6 to VB.NET, in hence my questions below:
I have to write a function that returns array of strings.
How can I initiate it to empty array? I need it since I have to check if it's empty array after it returns from this function.
Is list of arrays better for this purpose? If I use a list - Is it empty when it firstly defined? How can I check it it's empty?
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;
* * *

Now the first one is fine - Ext_Volume is result of the string between the strings <Volume> and </Volume>. <Volume> and </Volume> are unique so this is straight forward.
However the second one - "^FDExp:" is unique, but "^FS" is not unique. There are occurances of "^FS" before and after "^FDExp:".
How do I get the string to search AFTER the occurrence, not before etc?
