Determining Double_Click Event?
Sep 29, 2011
My current situation is a brain teaser for me, and I wish I could provide code that I have tried but quite frankly - i have no idea how to even start. So this is my situation; I have a tab control, this tab control holds the names of Departments for a Lay-Away manager. The user has the option to click a static tab, "New.." and add a new department. When that happens, the new tab controls name is added to the settings, and a new list-view is created, and named "lst & DepartmentName". The problem is, I have no way of knowing when the Double_Click event of the this list that may, or may not exist happens. I have a method of determining which list is currently active, working with a timer to set a certain value the name of the list, sort of like
Dim lst = GetAllList(TabControl1.SelectedTab)
cList = lst.Item(0)
Considering there is only one listview per tab, it will always be 0. So, question is - How could I determine when that particular listviews Double_Click event happens ? Then I will use it to call a certain Button_Click event?

I have a list of objects, each with several events. I can add an eventhandler to each object, so I can catch each item's events. But I would also like to know the sender's index in the list (ie, was this object the 3rd, 5th, etc, item in the list?) I'm guessing the object doesn't "know" its position.I could give each object an index number property when it is created and added to the list, so that information could be passed. However, I would have to reindex every item everytime I use remove, insert, etc, methods.

I am writing a simple program to perform a task at work. It is an update application that will allow end users to update software themselves.I have come up against a problem though. In order to fully complete the installation, the latest service packs have to be installed. The machines are either running XP or 2000 and need updating to the latest service packs.The problem is I cannot find any code that will let me determine the service pack, all I have is:
HTML
MsgBox("Computer's operating system version: " & _
My.Computer.Info.OSVersion)
This finds the OS version, but I don't seem to be able to determine the SP from it. What I need to do is make a piece of code that will find the OS and SP, and then download the latest SP.The service packs are as follows: 2000 needs SP4 and Rollup 1 and XP needs SP3. I value will need to be returned and then stored to create and IF statemenet, but I am stumped on how to find the SP.

In my code behind I'd like to be able to tell that I'm running my web site project in Visual Studio (either Debug or Release).I was considering testing for "localhost" but that's not perfect because we could be testing it locally on the server.

Is there any easy way to determine the IP address for the computer that an app is running on. I looked through the System.Net namespace and didn't see anything of the sort.
Basically, I want to display the IP address to the user, instead of walking them through how to do an "ipconfig". They then can put that IP address into another app, so the one app can talk to the other via UDP.

I have written simple code to determine country location using the suffix on the url eg..cn, .se, .br etc. even if its possible to determine country or location using urls that end in .com or .net? I was just reading up on something and found online apps that can determine location/country from the ip so how would I determine the ip or look it up using the url? can I do this in .net?
OK
So I have the following code and I get an exception when the url is invalid or faulty, can anyone help me to catch the error and add the url to another list and continue with my loop.
Public Sub getIpAddress(ByVal querylist As ArrayList)
Dim IPList As New ArrayList
Dim badList As New ArrayList[code].....

I'm just asking for suggestions for a secure way of determining what type of application my VB.NET application will load as. For example, I intend to distribute my application to internal and external customers. There are differences in features etc. for internal and external customers. What secure way can I tell the application to load as 'internal' or 'external'? I want to avoid the command line (passing in an argument) or the application settings.

I've got this problem where I'm supposed to be determining whether a string is a word or not. not exactly.Its supposed to just make sure each string has at least 1 vowel, and each vowel is surrounded by consonants. If it meets those requirements it'll be accepted, if not it'll be rejected, but I've already got that part figured out. I think I know a horrible way to do it, that would take a very long time, but I'm thinking there has to be a much easier way..

When trying to determine the Architecture of an OS, I ran across IntPtr.From reading the documentation, I saw this: Quote:The IntPtr type is designed to be an integer whose size is platform-specific. That is, an instance of this type is expected to be 32-bits on 32-bit hardware and operating systems, and 64-bits on 64-bit hardware and operating systems.
Since the size of IntPtr is intended to be the size of the architecture, would it be feasible to test the size and determine the OS by that? Or is there a better way?
I was thinking there might also be a way via WMI, but I don't want to use that for compatibility reason.

I am looking for a method to determine an applicants age from a masked text box(date). Below is what I am using but I wnat to utilize vb.net code instead of inherited datediff from VB6, also this method rounds off the age e.g 44.9 to 45 which is not acceptable.
Below is what I am currently using, looking for a better way.
Private _age As Int32
Private _SixQvar As Int32
'This determines the age of the client and sets the value of _SixQvar

I'm trying to write some generic code in VB.NET that determines whether or not a SQL server database table contains an identity column and, if so, to return the name of that column.I'm working in Visual Basic 2008 Express and have created a SQL database, "MyDatabase" with 1 table called "MyTable". Within that table, I've got 3 columns, "ID", "Column1" and "Column2". I know, I know... inventive names. Under column properties in the Database Explorer, I've set the "ID" column "Identity Specification" to "yes" and have set the "Is Identity" value to "yes"

I have a simple app that just shows the current time for specific locations around the world. I need to have it adjust for daylight savings time. I *THOUGHT* I'd already coded this but....
I thought I would use "Today.IsDaylightSavingTime()" and add 1 hour to the clocks. It isn't working?
If Today.IsDaylightSavingTime() Then
HawaiiOffset = HawaiiOffset + 1
PacificOffset = PacificOffset + 1

In my order program, I need to determine if the quantity ordered is full boxes.For example - all of our parts/products have different box quantities, and when a customer orders a certain quantity, I want it to do nothing when I type in the quantity IF the order quantity is even boxes, If it is not even boxes, I want a pop up form with three radio buttons to come up. The three radio buttons will have the next higher even box quantity, the next lower box quantity, and to keep the current quantity and apply a broken box charge. I have this pop-up form done except for determining if the order quantity is an even number of boxes, and then determining the next higher and next lower.
Just to clarify - let's say a customer orders a part that has 60 pieces per box. If he orders 180 pieces, nothing happens and you can continue to put the order on. If he orders 200 pieces, a pop-up form with 3 selections - "keep current quantity and apply broken box charge", or "Change Quantity to 240", or "Change Quantity to 180" comes up.

What methods are out their for determining how I should add the values up, with a decimal or double? I prefer not to have excel return the actual range for simplicity sake but will do if I need to determine if it is formatted as currency.

I'm running a bunch of automated tasks in a thread I'm creating via the Thread class. So I'm not using a BackgroundWorker.
During parts of the automation, the thread may exit. This is normal. But when the thread completes, I need to finish up some additional tasks. I can anticipate all of the conditions in which the thread closes, but I'd rather not to do the final tasks at each point, as this will create a lot of redundant code.
So instead, I wanted to write an event that is triggered when the thread exits. I looked through the Thread class, but all I could find was the ThreadState property, which has a Stopped property. But, when I try to add a handler to that property, it doesn't allow me.
