VS 2008 - Take A String Of Variables With A Common Delimiter And Break It All Back Out Into Separate Variables

Dec 11, 2011

Last year (2010) I came across a FANTASTIC command that allowed me to take a string of variables with a common delimiter and break it all back out into separate variables (possibly an array) with one statement.

[Code]...

As long as the delimiter was a unique specifiable character, this one-statement command could break it out into elements. my memory and point me in the right direction.

VB - Splitting A String Into 3 Variables

Jul 11, 2011

I need to split one variable into 3 variables. For example I have a variable called Data and it contains AAA00000001. I need to have them be split between the "AAA", "0000000", and "1". I looked at the Split() function but didn't get a clear example for this situation. The reason I need to do this is because I want to store these 3 variables into fields for a MySQL database.

Grouping String Variables With Their Names?

Dec 13, 2010

I am trying to reduce the amount of code I have and make it more maintainable and flexible. (I.E Do it the right way). I have a bunch of (48) Form controls (text boxes) and when I click next on that form I save all their text values to some 48 global string variables. The names of these variables are the same as the Text Boxes but with "_saved" appended to them.

For any given operation instead of having a separate line for each control it's nice to just use a loop. I can easily write some code to operate on each Control (set visibility, enabled etc) by using Me.Controls and a For Each Loop. I can even make collections of fractional groups of the 48 controls. For example, If cntrl.name.startswith("sometext") collection.add or perform some other operation only on that subgroup etc.

I'd like to do something similar with my Saved Public String Variables. For example I would like to do the following loop somehow but don't know how to group Variables together and keep their name in a way where I can define that array or collection on 1 line or just a couple lines.

' But this next line only groups the values
Group_of_string_Variables = {Var1, Var2, Var3, Var4}
For Each Name_of_String_Variable In Group_of_string_variables

[Code].....

But I can not access the name of a variable or find a way to easily group in key/value 48 different ones without needing much more than 50 lines of code to make either a 2-dim array, a collection, or a hash.

I'm sure someone will tell me I should be doing it a completely different way. That would be ok as long as I don't have to change too much of my other code. I thought of making an object of some kind instead of a variable so I could access 2 object properties- name and value then I could group those objects in a collection as I have done before. But that seems like it would be many more lines of code and I'm not sure it would work.

Assigning Variables To A 2 Dimensional String Array?

Feb 21, 2012

I have a form that asks for a name, and a phone number, it has 3 buttons, a add customer button, show list button and an exit button. When the add customer button is clicked, it increments intCustomer variable, formats the phone number, makes sure only the first letters of the name are capitalized and creates an ID that is the first 4 letters of the name plus the customer number, the show list button takes ALL customers added to the array and displays them into a multi-line text box, like so:

ID Num Customer Name Phone Number
JOHN-1 John Harry Peters (111) 111-1111
Paul-2 Paul J Rodgers (111) 111-1111
Etc...

The area where I am completely lost in, is how to add the consecutive customers to the array, in the correct way. here is my code in its entirety

Public Class frmCustomerName
Dim intCustomer As Integer = 1
Dim names(9, 2) As String

Sql - Inserting Variables Into A Query String - It Won't Work

Apr 22, 2010

Basically i have a query string that when i hardcode in the catalogue value its fine. when I try adding it via a variable it just doesn't pick it up.This works:

Dim WaspConnection As New SqlConnection("Data Source=JURA;Initial Catalog=WaspTrackAsset_NROI;User id=" & ConfigurationManager.AppSettings("WASPDBUserName") & ";Password='" & ConfigurationManager.AppSettings("WASPDBPassword").ToString & "';")

This doesn't:

Dim dt As New DataTable()
Dim username As String = HttpContext.Current.User.Identity.Name

When I debug the catalog is empty in the query string but the WASP variable holds the value "WaspTrackAsset_NROI"

String Variables From Random Access File

Nov 17, 2010

I'm tasked with the job of creating a javascript version of a units conversion application written in vb6. I have the source code but I don't have vb 6. The source code uses a dat file to hold a conversion array (unit type, unit, xfactor, plusfactor). Getting the data out of this file would be good to me. I tried creating a little app in vb 2010 to write the data from that dat file to a txt file using essentially the same code as the source code. And that has been somewhat successful (took a while to figure out the fixed string business). Now I can pull the data out as an array. The math elements of this array look fine but the strings are somewhat read-able but too garbled to use. I can't seem to fix that by changing the character set/encoding.

Use Of Variables Across Several Forms In Application - String Manipulation?

May 5, 2010

I am a beginner trying to write code. I am creating an application that is a questionaire with 3 forms that have questions for the user with text boxes, list boxes, and check boxes for response. Some of the text boxes with the user response are on different forms. Will that cause me problems? I would like to write code that will combine a literal string with responses from text boxes and string snippets which are inserted based on check box condition. I think I would like to create the string to be printed to a RichTextBox and then output to peripheral printer. How do I make inserting or not inserting a string based on check box condition? How can I trim the response string to allow a output string without annoying extra spaces and such?

Using String Variables To Point To Text Boxes?

Jun 12, 2011

I was wondering if it is possible to point to a textbox created in the form designer via a string variable. Basically, I'm creating a golf management system with a feature allowing a user to define their own course. Each hole has a corresponding textbox into which a user can input the hole's par and then the system should total up the first 9 pars, the last 9 pars and then all 18 pars; displayed in 3 different textboxes.

The input textboxes have been named txtP1, txtP2, ..., txtP18, so I was wondering if I could simply concatenate a loop control variable onto a constant of "txtP" to point to each input box.

This is what I have at the moment, but it's throwing up errors saying that .text is not a member of string.

Sub UpdatePar()
Dim inpar, outpar, totalpar As Integer
Dim pointer As String
