Possible To Split Up File For Readability?
Oct 29, 2010
I'm writing a program in Visual Basic 2010. It's a HMI (Human-Machine Interface) and therefore has a whole whack of buttons that just send commands to other devices. As a result, there are a huge pile of event handlers for clicking buttons that can't really be broken down into modules (unless my understanding of modules is wrong). Essentially, I'd like to be able to move all the event handlers, for, say, button presses to a different file. Can this be done or is it important that they stay in "MainWindow.xaml.vb"? (All my buttons reside in one fullscreen window, some are hidden by tabs).

While working on a project I have come across a way of not having to check if a string isnull or empty
dim sb as new stringbuilder
dim bob as string
sb.append((bob & string.empty).padLeft(10, " "))
Here, bob is not instantiated but doesn't throw a null reference error. In situations like this, is it more readable to do the above code or the below code?
if string.isnullorempty(bob) then
sb.append(string.empty.padleft(10, " ")
else
sb.append(bob.padleft(10," "))
endif
I personally think method #1 is more readable and maintainable.

Since .net 4.0, is the new ettiquette to use syntax such as:
Private Sub Main()
MyMethod(AddressOf AnAction)
End Sub
Private Sub MyMethod(ByVal toDo As Action(Of String, Integer, Boolean))
toDo.Invoke("Tom", 1, True)
End Sub
Private Sub AnAction(ByVal p1 As String, ByVal p2 As Integer, ByVal p3 As Boolean)
End Sub
[Code]...
This goes the same with Tuples/Func too. It is nice to write but feels a bit sloppy in places. Why would anyone want Tuple(Of T, T2, T3, T4) over a nice class type? My actual piece of code has these nested, so it passes the Action along in a chain of methods.
Sorry for the VB example, AddressOf is just VBs way of saying new Action(AnAction). Also I just wrote this into the browser so it might not compile either.How to people feel about reading and using these compiler generic actions as opposed to proper special entities crafted for their exact requirements in the solution?

I just converted the following code from c# to vb.net. It is functional and works correctly with my company's firmware/devices. My next challenge. Previous serialport code used much more readable structs which where then converted (after building a packet) into byte() automatically as part of the serialport encoding. (this is my understanding)How could I
1. morph byte arrays 'ToSocket' and 'ToMTP' below into structs and
2. convert into byte array for Socket.BeginSend(byte(),.....) to stream out to remote devices?
Imports System.ComponentModel
Imports System.Text
Imports System.Net.Sockets

I have a File i need to read and extract a few values from each line in the file. my problem as it stand the file i'm reading has some unconsistatcys as all of the Strings are seprated by " " but the integers are not they are Without any Speech marks to define them. I have thought of a methord to deal with this but i can't for the life of me think how to achive this.
As the file has unconstancys to be used with a standard " " extractor, the only consistancy is that there is allways a " before the integer and after attached to another column. this could be used i thought.
a Sample of the data is only one line:

I am trying to split a long string based on an array of words. For Example:Words: trying, long, array Sentence: "I am trying to split a long string based on an array of words."Resulting string array:Multiple instances of the same word is likely, so having two instances of trying cause a split, or of array, will probably happen.

I have read the contents of a text file that looks like the following lines into vb;
this_date = "1-2-09"
// user input
//user input
this_date = "2-22-2009"
[code]....
(there is no limit to how many "this_date" lines or "//user input lines" there are in the file and additions are made often ) When I read the file in vb I wish to only capture the last "this_date" only as the rest are irrelevant.

I wrote a program for my company and it imports a .csv file i then split it by the ,. My problem that I now see at the end of the project is that 98 out of 1400 items have, in the descriptions that im seperating. This creates a problem when search for items. My question is is there a way to use more then just one char to split it? i was thinking of splitting using ",".

I am reading a text file with mostly alpha characters. the content is not really relevant but the size of each line is very important. The process I will feed this text to will require each line be no more than 50 characters. So I will pre-process the text and add line feeds to make sure that happens.I tried several VB.NET regex like ^.*$ but that doesn't really break up the lines by 50 characters. I would take the result and iterate through each match and then cut it up and write it to an object in memory. Can this be done with a single regex pass?Otherwise I will use a streamreader and on each line check the length and if <=50 write it out with a streamwriter. if >50 cut it up in sections of 50 and then use streamwriter.
A brief example of my text:
