How To Create Variables From Strings In ArcObjects
Jun 30, 2010
If I have a list box or something that has a list of like 4 years (like 2006 through 2009), how do I programmatically make variables of these years with names like pTable2006, pTable2007, etc (as ITable of course). If this isn't possible and I have publicly declared these tables in the declarations (like pTable2006 as ITable, pTable2007 as ITable, etc), how can I programmatically assign these variables based on user choice?
What I'm asking is, if the user wants to choose years 2006 and 2007, how can I write this:
pTable & ListBox.Items.Item(0) = [table path string] & ListBox.Items.Item(0)
(please ignore the syntax of the "listbox", I'm just trying to come up with an example)
Whenever I put something like pTable & "string", I get an error.

I need to pass two variables/strings to a background worker at the same time. he background worker needs to return the first variable, and the time consuming boolean result of the second variable.From what I have read, I can only pass an object that contains multiple variables.This is where I get confused

I have a "if This > That then" statement, that doesn't seem to work, as it triggers regardless that "This" is smaller than "that". Does it matter that these variables are marked as strings vs integers?

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'm trying to create a number of strings based on one long string that i'm passing.
Basically this is an example of my long string
StrMain = AL123456 - PR123456 - RD123456 - LO123456
So in this case I want to create 4 separate strings.
Str1 = AL123456
Str2 = PR123456
Str3 = RD123456
Str4 = LO123456
But there isn't always that many or there may be more so I need to count how many - there are and with that then create the amount strings needed.

We have these xml formatted .config files that come with all our ASP.NET programs. Well they have keys that need to be populated and I am unable to understand how to create a variable in xml and use it. The articles on variables in xml all seem to be talking about some other type of variable than I am familiar with. I am used to working in C or other programming languages.
I want to do something like
MyVariable = "SomeString"
<add key="Key1" value=MyVariable>

I would like to make a program that generates a safe passwords for people to use. I want to make the passwords vary in length, include numbers, letters and upper case letters. I've been able to write code that prints out a random string but it includes unrecognized characters for most passwords. How would I write the code to create a random string that has parameters? (in this case upper case lower case letters and numbers).

I have a page where the page loads with the code as shown below. Pretty much every other sub on the page uses the variables gFilename, gPicType and gPicPath. In every other routine I have to go through the process of recreating gPicPath (as per the if/then block in the code). How do I create these variables ONCE, and then store them so that all the other subs can access them?
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)
' check to see if this is the first time the page is loaded.
If IsPostBack = False Then

I am looking to create a function in which I can pass in an integer (count) and create an amount of picturebox's based on the count.For example if I pass in an integer count, it should do this, only I don't know the correct syntax for it.[code]I am making a huge list of pictureboxes that will scroll on a form, 5 showing at a time.Also, if there are a huge amount of pictureboxes, will I be better off keeping like 7 pictureboxes on the form and keep rotating images throughout? Images are coming from a folderlist in a listbox (so I can easily pull the path of the image from an index).

I want to monitor more than 10 folders on different machines by using SysTemFileWatcher. I create a class called Watcher for doing monitoring. So, for each folder I have to call that class once with a new thread. I want to name each thread with its own name like: T1, T2, T3 ... for easier controlling them. It is not nice if I declare each thread like:
Dim T1 as Thread =new Thread(Address of Watcher.StartWatcher)
Dim T2 as Thread =new Thread(Address of Watcher.StartWatcher)
...
Dim T18 as Thread =new Thread(Address of Watcher.StartWatcher)
How can I declare thread names dynamically with the names just like that. I have tried to use Thread array() but it doesn't work.

Forgive me if this has already been covered in a previous post. I am considering using VB.net for a project but need to know before I dive in if it can perform this particular functionality. The application I wish to develop would need to be able to create html and email templates using variable tokens - what I mean is that users would need to be able to insert into their html or email template previously assigned variables that would send dynamically generated text from the database - so, for example, they could write in their template {title}, or {firstname} {lastname} which would then be replaced by the data from the db.

I put "isolated context" in quotes because I don't know what else you would call it. Basically, in C#, you can do this:
{ int i = 0; }
{ int i = 1; }
The curly braces create an isolated context which allows you to declare two variables with the same name in the same method or property logic. Is this possible in VB.NET? Also, what do you call this aside from an isolated context?

I recieved a gift recently visual studio 2010 ultimate a nice suprise I have been repairing and building PC's and networks for years working in local shops and buisnesses, but always wanted to learn programming so my GF purchased this for me nice suprise. So here is my beginner question. I am making a program that will take check info ( check number, amount, date and person or buisness wrote to). I have no plans on using it just trying to learn variable structures and arrays and thought this type of program was a good start. Now I would like to take the text of a text box in runtime and use that to input a new check number into the variable structure. Just so I am not confusing anyone I will write the basic code
[Code]....
So what I would like to do is use a textox labeled check number to add check numbers into the checkrecord structure instead of having to add them into the code manually is this possible?

I have text file that is saved as comma delimited. There are 3 columns with x number of rows. I cannot seem to figure out how to create an array that will store all three columns with the variable intProductArray as the length of the array. I have been opening the file with only one column and putting it into a textbox and using the lines of the textbox as the variable for length. I cannot figure out the array for all 3 columns.
Private Sub btnChoose_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnChoose.Click

I need a bit of advice. I am working on my project with the listbox. I know how to create a source to get the strings from the text file using ReadLine method, but I have no idea how to split the strings in the text file by on the third commas and ignore the other strings while select with the matched strings on the listbox for each row.Here it is an example listbox Here it is an example items on the listbox
random item 1
random item 2
random item 3
random item 4
random item 5
And here it is an example text file.
example strings one, any strings 1, any random strings 1, other strings 1, final end of strings 1
example strings two, any strings 2, any random strings 2, other strings 2, final end of strings 2
example strings three, any strings 3, any random strings 3, other strings 3, final end of strings 3
example strings four, any strings 4, any random strings 4, other strings 4, final end of strings 4
example strings five, any strings 5, any random strings 5, other strings 5, final end of strings 5
The listbox is display the list of an example items, so if I select the "random item 1" item on the listbox, it read the strings through in the text file on the first line to get the strings on the third commas in the same line which it is (any random strings 1) to split it while ignore the other strings (other strings 1, final end of strings 1) that come fourth and fifth commas. So, if I select the "random item 2" item on the listbox, it read the the strings through in the text file on the second line to get the strings on the third commas in the same line which it is (any random strings 2) to split it while ignore the other strings (other strings 2, final end of strings 2) that come fourth and fifth commas and so on...That is what I am trying to achieve by select the each listbox item to get the correct strings for each line in the text file that come on the third commas while to ignore the other strings.
