Creating An Array From A CSV Text File And Selecting Certain Parts Of The Array?

Mar 20, 2011

I have a Comma Separated value file in .txt format... simply put, its a bunch of data delimited by commas and text qualifier is separated with ""For example:

"So and so","1234","Blah Blah", "Foo","Bar","","","",""
"foofoo","barbar","etc.."

Where ever there is a carriage return it signifies a new row and every comma separates a new column from another.My next step is to go into VB.net and create an array using these values and having the commas serve as the delimeter and somehow making the array into a table where the text files' format matches the array After that array has been created, I need to select only certain parts of that array and store the value into a variable for later use.... how to make the array and selecting the certain info out of it..

Object Creating Code & Passing Values To SR?

Mar 29, 2011

This code works, as is, on my system. Problem lines are commented out. The last three commented lines are the problem.It creates the objects alright but a line that should send a message into the list box doesn't work. I am almost sure that the problem is in passing information into the sub routine. Forgive my use of ALL CAPS as it helps to see my comments on comments. A few comments in passing information to SRs would be helpful.

Also, how it is that I can comment out the .Name option and it still works?(I hope that this shows up properly. If it ends up as a big useless paragraph, I will repost it after learning how to do it properly.

Here is my

Creating An Array Of Controls?

May 19, 2009

I need to be able to refer to a set of controls on a Windows form using an array, but I'm having a few difficulties.

The Windows form (WForm.vb) contains two textboxes (TextBox1 and TextBox2).

In Module1.vb I have created an array reference to the textboxes thus:

Public wf As New WForm
Public ReadOnly TB() As Control = {wf.TextBox1, wf.TextBox2}

Then, in WForm.vb I have tried to refer to the textboxes via the array:

eg.

TB(0).Text = "Change text to this"

I know that the array is referring to the textboxes, because when I hover the cursor over the line 'TB(0).Text = "Change text to this" ' in debug mode, I get the following:

(0)|{Text = "Change text to this"}
(1)|{Text = ""}

but for some reason, the text in TextBox1 on the form isn't actually being changed!
(There is obviously no problem with change the textbox's text at this point in the code, because I've tried substituting the array reference 'TB(0)' with a direct reference to the textbox 'TextBox1', and the problem disappears.

Creating An Array With A Variable Value?

Mar 22, 2010

i want to declare an array with a name that is the value of a variable. I need to do this because i want to create arrays from a text file that i'm reading.Basically, if someone could make this work then i should be able to change it to fit my use.

Dim var1 As String = howdy

Dim var1() as Integer

In this case i'd like to be declaring an array with the name 'howdy' that stores integers. In reality i'm looping a bunch of read names and would like to create an array for each name i read- but i'm quite capable of sorting the rest.

Creating A Routine To Decode A 0-255 Number Into Specific Values?

Oct 22, 2011

This is kind of a brain twister. First, what it involves. I'm writing an application that is working with values sent to and received from an 8 bit micro-controller. There are 8 bits of specified values. Here they are. bit1 = 1, bit2 = 2, bit3 = 4, bit4 = 8, bit5 = 16, bit6 = 32, bit7 = 64 and bit8 = 128.I made a routine that uses 8 checkboxes to add the values for sending them to the micro-controller. That wasn't too hard. In my appp there are 8 checkboxes. Each checkbox assigns one of the specific bit values to a variable (or subtracts it when unchecked). The total of the variable is then displayed in a textbox and ready to send.Now the hard part that ed to take any number between 0 and 255 apart in values that will be a combination of the numbers (1,2,4,8,16,32,64,128) above and show each checkbox which is assigned those numbers to be checked.

Correct Way Of Creating An Associative Array?

Aug 18, 2011

I'm a PHP guy and in PHP I would do something like the following:$variable = array('0001'=>'value1', '0010'=>'value2');

I'm pretty new to VB.net so I'm wondering how to translate the above code to VB.net

I think I have to use a dictionary:

Dim variable As New Dictionary(Of String, String)
variable.Add("0001", "value1")
variable.Add("0010", "value2")

Is this the correct way of doing it or should I use something else for this?

i am attempting to create and then update data in Labels using VB2005.I create the label when the form is loaded using this for loop

For j As Integer = 1 To count
Dim name As String
Dim m As String
ReDim L(count)

This creates the labels and text boxes in the form. Later in the program I would like to change the text within both the T1310() and T1550() text boxes and I am attempting to do so with the following code.

For j = 1 To count
status = OP930_SelectModule(j - 1)
status = OP930_SetWavelength(1310)

[code]....

I get errors on the Blue lines. Everything compiles fine, but when the software goes through the loop I get the error "NullReferenceException was unhandled"
