VS 2010 Check For Element Or Keep Trying Until Element Is Found?
Feb 21, 2012
I have been doing well and also I am a noob I know it and you know it a lot has started making sense and I am evening figuring new things out without using Google but of course I have hit another snag in my program so here goes
I am waiting for an email to arrive (the page automatically refreshes) and then I want to click the link (I do not need to click to open the email or anything like that) I also have the code to click and navigate to the address reason being it was the only way I could figure out how to stop it opening in a new window on IE
So my only problem is I need a way to check every x seconds for the element and then if its there proceed with my code and if its not wait and then check again or however this is done in VB.If this is not the way its done please point me in the right direction the code I am using to find and then navigate to the link is
Dim emailpageelements As HtmlElementCollection = WebBrowser2.Document.GetElementsByTagName("a")
For Each emailver As HtmlElement In emailpageelements
If InStr(emailver.InnerHtml, "https://twitter.com/account/confirm_email/") Then
WebBrowser1.Navigate(emailver.InnerText)
I would like the following function to return Nothing if the element with the specified key is not in the collection. Instead, it returns an error - something to the effect of "no element found"
Public Class MyCollection Inherits System.Collections.ObjectModel.Collection(Of MyType) Public Function FindByActivityKey(ByVal searchValue As Integer) As MyType
I am using NiceEdit to format text in text areas, it displays a toolbar over the specified text area, I created a test page, its working, I Response.Write the content of the text area after being formatted, and its okay, I created a break point to see whats being read, it was all fine.Now I moved to the real page where I should implement this text formatting, it simply did not do anything, the toolbar is shown and its working, but when I submit, nothing is being stored, i created a break point and the content of that text area was nothing, empty "".I went further and put Response.Write(textArea.text) then Response.End() and I got the error:XML Parsing Error: no element foundJust in case, the script I am using for the formatting NiceEdit toolbar, and this is the same script i used in my test page and worked just fine, the script is:
I have a number of rewrite rules for a lot of things that I did in IIS7, like removing trailing slashes, canonnical URLs, lowercase lettering, and such. IIS altered my web.config, and everything works fine on the website, like it should. But in the Visual Studio web.config, the opening < rewrite > statement is underlined in blue, and at the bottom of VS, it says that the element 'system.webServer' has invalid child element 'rewrite'. But this is how IIS made it. I didn't do this manually. Should I be concerned with this VS error, or should I just leave as be, since it's working how it should work? Here's an example of my web.config:
I am having problems finding an named object declared in XAML in my codebehind file.I want to initalize a ViewModel from inside my View. However I also need a reference to the ViewModel in my code behind file (basically for navigation support, handling events, etc. that I cannot do easily from my ViewModel)[code]However I get a null reference exception when I'm trying to access the ViewModel in my code behind:[code]Some more research shows that the FindName call for "ViewModel" in InitalizeComponent returns null. I tried reading up on XAML namescopes etc. but as far as I see, this should be a simple case and just work, no?
Is there a way to control the way a browser behaves such as if I click on this link it doesn't navigate to that link but instead show me the source code behind that button?

[code]...
Is it possible to reference a structures element by the element's name in a similar way to that shown above. The code shown above does not work, as the expression obj(i).[elementName] does not work as hoped.
I want to take a field from a table and place the content into a collection. The collection is not supposed to have any duplicates. This is my code sofar... It does not work.

I'm using HtmlAgilityPack to parse HTML. I want to check if an element has a specific attribute. I want to check whether an <a> tag has the href attribute.
Dim doc As HtmlDocument = New HtmlDocument() doc.Load(New StringReader(content)) Dim root As HtmlNode = doc.DocumentNode Dim anchorTags As New List(Of String) For Each link As HtmlNode In root.SelectNodes("//a") If link.HasAttributes("href") Then doSomething() 'this doesn't work because hasAttributes only checks whether an element has attributes or not Next

I'm using a web browser in my vb forum and it to find a certain element then click it when the element loads. The thing is though i don't want it to use the actual mouse if you understand what im saying. Like a appliation thats clicking certain elements but i can still use my mouse to do stuff that i want. Here's the code i have so far
I haven't managed to find it and it is driving me nuts! If I have a structure such as

If I want to change a single element of one of the elements of the array, for example the DayHi field of the 0th element, then the code ATRList(0).DayHi = 4 causes the error: Error3Expression is a value and therefore cannot be the target of an assignment. Now I could get round this by reading all the items out of the 0th element into newATR, changing the field I'm interested in and then doing a "ATRList(n) = newATR" but there must be an easier way?
I have a webbrowser control with a static HTML page in it, i wanted to loop through each of the DIV items, and look at the class attribute within them. When i run my test, the class attribute is always blank? I know they have a class attribute i checked in my HTML
there are any nifty in-built .net methods that can essentially return either the number of occurrences of each element in an array, or simply return the modal value.
I'm currently learning VB.net and can confidently connect to databases and return results to comboboxes run stored procedures ect to datagrids, However I'm wanting to find an online tutorial for doing loops with data so for example
I want to display each element on a page in a structured format so as to make a visual representation in seperate entities (labels maybe) of the data like so:
Order number
line 1 (includes item and price in plain text on a page i guess using a label) line 2 (same goes)
Subtotal( )
The results and formulae i can do but it's simply how to split off the data from my dataset and display elements as seperates (also how will i dynamically create the lables as obviously i'm not going to know in advance how many order item rows will return )
Obviously this is not urgent but if anyone could point me at a tutorial or even better a few lines of code that will do this for the microsoft northwind data so i can mess about with it and play.
form method="POST" action=""> <input type="hidden" name="formtoken" value="33664efb6d22f84ff9dff62275fbb8a7" /> <input type="text" name="num" value="+97798""/><br/> Enter Message To Be Sent:<br/> <textarea name="msg" rows="8">
I've been trying to use the AutoComplete Extender from the ASP.NET Ajax Control Toolkit, however I've been having tons of trouble getting it to actually work.
