This code is supposed to check if an item already exists in a ListView, and if not, add it. But it still adds it even if it was already there. All variables are set and fully working. The addable string is in an array.

I'm creating a twitter account manager using the Twitter API. I have multiple accounts, over 10 of them. I want to automate all 10 of these accounts to do certain things, now the way I started to code the program was so that it would accommodate only one account, and all the codes worked perfectly and were managed by individual timers for individual processes that I wanted done. i could tweet between certain intervals, follow people who tweet certain things without me being on top of it.
Now the problem is that I've been trying to create new instances of subs that I've already created so that I dont have to create 10 new subs with the exact same procedures. I'm pretty sure it's impossible to create copies of subs dynamically or within a loop but it didn't stop me from trying. So question is how can I edit a program that was designed to accommodate and automate only one account, to potentially accommodate over a 100? I don't need codes or anything I need ideas so I can try them, but right now I'm completely blank.
I am porting an app from VB6 and I run into problems with references to functions and subs. Basically, let's say I have 2 classes added to the project, like this.
Public Class OOOOO
Public Shared Sub BBBBBBB(ByVal FileName As String)
...
Call CCCCCC()
Call DDDDDD()
etc.
...
End Sub
[Code] .....
I had to make the BBBB() shared to be able to call it from another function AAAAAA() from another class PPPPP. However, I get error on the references in the BBBBB(), that CCCC() and DDDD() have to be made also shared (so instead of 1 error I got number of errors).
When I tried to make them shared as well, I got tens and tens of errors due to other references of both variables and functions.
When I use a For loop in a For loop the Contains Statement dosen't work! Even my custom one! I even tested mine and it works 100% And neither that or the String.Contains function work inside of For Loops And, I know both of them use loops to search through a string.
My function(It will atleast search once):
Function RealContains(ByVal load As String, ByVal needle As String) As Boolean
load = load.ToLower

I have a sub which creates an XML file but the thing is, all the parameters are 'hardcoded', so I decided to give some inputs so each data in each node is customizable. Now, I would like a loop to read the text in textbox1 and assign that to variable one, do the same for textbox2, write the node, loop again (using the same variable) and assign that variable a value in textbox3 and write the node.
I can while loop to write nodes, but only for fixed data or data with 500000 variables for each loop. Is there any way to do this such that on each loop it dynamically sources the variables data from the 'next text box'. i.e. One first loop uses textbox1, second loop it knows it has used textbox1 .'. it uses textbox2 etc... Is there a way to do the same thing but write back to text boxes in an order, knowing what was previously written.
I have a bunch of XML's that need to be put into an SQL database. One XML represents all orders for a certain department of a store. The problem (for me) is that in one XML there can be (and are) multiple orders (called distributions in my case.) The XML looks as follows (truncated):
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<order><process_id>322867</process_id>
<key1>RET</key1>
<key2>40_134985</key2>
[code]....
So in this example I have two 'distributions'. Now I can get all data out of the XML fine, which I do like this:
get xml data
awsFeed = XDocument.Load(fileName)
Dim orders = From order In awsFeed...<order> _
[code]....
However, in this case my SQL input would have to result in 2 entries, because there are 2 orders. Both entries would have the same data, except for different entries. I know how to post to SQL, that's not the problem. My real problem is, how do I 'loop' it through the XML. I think i'm looking for something like:For each 'distribution' in orders -> put into array.Or something like that. After that I could query the array and put it in the database.
I have an array of approximately 1000 classes. All of these classes must have one of their properties changed to the same value. I need this to be as optimized and fast as possible.
Would LINQ be faster than a for-loop? Any other ideas for faster execution?
So I am writing a program that uses ArrayA(10) and ArrayB(10) and uses Do loops to output the sum of ArrayA(1) + ArrayB(1) in one column then the difference in the next column, then the product in the next column, then the quotient in column 4 of a Matrix(10, 4) in a listbox. And continues doing this until there are 10 rows of 4 columns. I was wondering for tips on how I can get this done.
View 6 RepliesI've wrote this code to accomplish what the image below looks like. This works fine for anything that is around 40x40 but if I try to do 100x100 it takes forever and sometimes errors out with a window handle error. Once it gets around the 40th column the labels start adding slower and slower. Is there anything I can do to make this more efficient? I added the backgroundworker routine in there to see if it would speed things up at all but it doesn't.

Been given an assignment to create a space invaders game. Although there's a long way around, is there a way to make my code smarter.Here's the section to make a row of invaders so far:

Dim numberofinvaders As Integer = 11
'set of invaders (vertical)

So what I want to do more precisely is have the value of setofinvaders to change how many rows of invaders vertically in a loop.

I've previously posted with regards to searching for a string within Excel, although the replies were enough to get my application 'working' the solution was riddled with over-complicated methods.Therefore I bought some books and figured it out for myself and came up with the below (which works like a charm may I add).
Dim oExcel As New Microsoft.Office.Interop.Excel.Application
Dim oBook As Microsoft.Office.Interop.Excel.Workbook
Dim oSheet As Microsoft.Office.Interop.Excel.Worksheet

None of these (even if combined) make ANY effect whatsoever.I have also saved the workbook on exit, again to no avail.
Trying to exit an application but can't seem to kill it without an error."An error occurred creating the form. See Exception.InnerException for details. The error is: The form referred to itself during construction from a default instance, which led to infinite recursion. Within the Form's constructor refer to the form using 'Me.'"The form hasn't loaded yet, it is still in the process of looking for a file to load, if the user doesn't want to specify a working directory, that is their choice, but I need to close the app since it can't continue without it.I'm stuck in a class and can't get back to the main form without it continuing to load everything up. I wan't to force a shut down. [code] I was trying to get back to the main form without loading any more from the class to kill it there. [code]

View 1 RepliesI find myself frequently turning off Intellisense because it adds wrong choices to my code. For example if I try to type "i " (without the quotes) it causes "int " to be put into my code. If I type "for " it may put "form " into my text.
Reaching for the ESC key constantly slows down my typing. (It's such a long way to reach for small hands). Is there an alternative way to exit out of intellisense without the highlighted choice being placed into my code, or is a way I can define a different key for this purpose?

View 4 RepliesI have a simple for loop with the following code
For i As Integer = 0 To 4
Snake(i).X = (120 - 20 * i)
Snake(i).Y = 120
SnakeBody(i).Location = New Point(Snake(i).X, Snake(i).Y)
Snake(i).Facing = 3
Next i
But for some reason I unable to debug it. I place a breakpoint on the line Snake(i).X = (120 - 20 * i) and When I try to see what the values are the second time the loop iterates it simply exits the loop.
the application I am developing does not exit completely. i.e. the process can be seen in the Task manager. This happens only when I click on the [X] button on the title bar of the window of my MDI form. If I use the File >> Exit in the menu of my application, it exits without leaving any traces. I have used the "End" method there. But the process stays when I click the [X] on the control box on the title bar.

View 2 RepliesWe have an application that works well on XP/Pro, Vista, Windows 7, Windows 2003 Server, Windows 2008 Server (32 bit) but is problematic on Windows 2008 Server (64 bit). The application uses an unsigned activeX control which may or may not be related to the problem. To install we need to add the program name and regsvr32 as DEP exceptions. Once that is done the application installs correctly and operates normally except when the application closes.
If a user clicks the 'exit' button our code basically says 'unload me' (where me = the main form of the application) and there is no code in the form_unload section of the program.
Everything works well on every Windows platform except Win 2008 64 bit where we get

I know I can exit a program by using the End statement.
But i was wanting to know how to check to see if the data has been changed since it was loaded and bring up a diaglog box up saying the data has been changed or not saved, would you like to save the data before exiting?
I will have a form that will have a yes, no, and cancel buttons.
