So I have[code]...
It would give me 5 instead 4 results, since <title>My Channel</title> is considered one of the item under channel. I'm just wondering if there is anyway to loop through only the 4 item elements.
I'm creating an application that will be visiting several different sites.Each site will have the same elements but not necessarily in the same order.On a previous post I was told to use the Select Case to choose between the choices.Can Select Case be used to choose between Webpage elements?Let's say that on one site the first web page element is choose button A but on site two it will choose button B.
Dim makeachoice As String
makeachoice = webbrowser1.element button A
Case signin

in VB is there any situation whereby x = Nothing is not the same as x is Nothing?Also, x <> Nothing vs x IsNot Nothing.
View 1 RepliesI created a method and pass the element type, id, and any inner text that instantiates a new html element. The last statement: Me.Controls.Add(element) adds it to the end of the page, but I would like it to be inserted in a specific position (between 2 divs within a form). What I am describing is very similar to this post on SO here, although it was for javascript.

I have this situation: a Form with a System.Timer in it (with AutoReset = False). The form has its main thread and the timer its own thread too (nothing new here). When the user press a button I need to stop the timer, wait until the timer thread has stopped its execution and do something more.
On the other side, the timer updates an item at the form so BeginInvoke is used. The code looks like this:
Button Code: Private Sub ButtonStop_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ButtonStop.Click
[Code]...
The point is that I wait the main thread to let the timer thread to end its work.The problem is that this code deadlocks when the user clicks the button when the BeginInvoke is going to be called. How a simple thing like this one can be done? Looks like I cannot find a good solution to this problem
So, I have an app that uses a SQL Server express db. I have about 80ish tables all with a primary key but no foreign keys. (The reason we have no foreign keys is because of how we do our sql client-to-server replication. It's not true replication but it's a sync system that was in place when we took over the app. We have no guarantee what records are going to make it to the database first when a client syncs to the server so it is possible that a record would make it to the database with a foreign key that points to a nonexistant record). We use a type-per-model convention. For each of our business objects there is a table in the db. We currently use stored procedures for every database transaction. This means for every new class there is at least 4 new stored procedures (crud). We have abstracted out our data access layer from our business objects. Each business object has a corresponding businessObjectDAO.
My question is, is entity framework feasible for me to move to? With no foreign key relationships I'm going to have to set up every association between tables manually.My biggest hang up right now is trying to figure out how I map my DAOs to the EF partial classes. Should I be creating one big .edmx or multiple? A lot of questions I know. This is my first big architectural type decision and I've been given the go ahead to make the change if I think it is beneficial and feasible. Maybe I should try Linq-to-SQL? NHibernate is out because we're not allowed using open source products in production (stupid, I know).
I have a Check Box that the use checks to indicate that a specific situation is present. When the User checks the box he gets a Message Box reminding him that the condition must be fulfilled. This works fine and the database reflectthe fact that the Check Box is filled.
At a later date, if the user calls this record and fills the form, the Check Box is triggered and the message Box appears in the middle of the form fill operation.
Is there a way to prevent this from happening. I want the Check Box checked but don't want the message box if the change is triggered by the fill process.

I need to write a program that requests a high number and a low number from the user, then the program searches the array and finds all elements within the two numbers. The program is used to search for past presidents, so if I type 43 for low number and 44 for high number, the program will display:
George Walker Bush
Barack Hussein Obama
I think I have an idea of how to search up to a certain point, but not to stop at a certain point....Here is the code that I have for that particular sub procedure:

I'd like to know how you can actually select(highlight) a program from a list of programs displayed in a list box in Windows Form. I've done research and most results end up with openFileDialog condition or have to manually type the directory path. But what I have currently is the display of a list of programs in a list box(like Add/Remove Programs) but I'd like to have the user launch it upon double-clicking or clicking on a button(after a program is highlighted).
In short, it's like selecting a program in Add/Remove Program but instead of the Uninstall button, I want it to be a Launch button. I believe I already have the executable path behind the codes with the registry so I just need to know how you can select, and launch.
