i want to add WPF Control to my windows forms application so i need to use element host but i couldn't find WPF Interoperability tab so i tried to add the reference and then add the control but i got this error why? and btw i tried also in C# and i got the same problem
View 8 RepliesI want to get the absolute host name from a URL that's in the format of a string. So far I have done it like this:[code]I need the host without the www for comparision purposes.If I have two strings "url...m" and "url...m" I'm interested in only seeing that they are both on the domain "url...m". Is there some fairly simple way to do this?

View 5 RepliesDoes someone know what api funtion to use for getting remote host name right now i use System.Net.Dns.GetHostName and the nbtstat -a function, but still have some computers that i dont get their host name but i do get their mac with send arp...so how cna i get their host names with an API call..
This is my code for dns.hostname ..
vb.net Dim myIPs3 As System.Net.IPHostEntry = Dns.GetHostEntry(hello)
Dim newhost3 As String = myIPs3.HostName
I have been trying to trace a list of urls by using the url to get the ip and then use that to assign it a country. When using DNS.gethostentry or even DNS.gethostbyname I get the following error:
SocketExceptionwascaught: No such host is known
Now I even tried fetching the url first using httpwebrequest to ensure the url is valid but the error keeps showing up regardless. I know there are a few urls that don't work but I thought my code would catch and continue.
Try
For Each prod In querylist
If myfetcher.getHtml(prod, userAgent, page) Then
prod = Regex.Replace(prod, "http://", "")

I am working on an addin/plugin for CAD software called Solidworks. I use it to batch process files (print, save, etc). One thing I'd like to add is a form that contains a stop button to stop the loop. The problem is that even if I use a background worker like I normally would for a standalone application, it still locks up when Solidworks is processing files. That's just normal operation for the program, the UI freezes when doing a cpu intensive operation such as loading or saving files, regardless of how I write my plugin. So my limited attempts at threading to get a form that won't freeze have been unsuccessful so far.
View 1 RepliesI have a (very) simple WCF written in VB which I can build and publish locally to IIS. Works great.
What I need to do is (somehow) deploy it to a different server which does not have IIS. It's supposed to be run as a windows service.
how to do this. All directions on MSDN seem to be for VS 2010 (we're using 2008).
I read some posts in the vb.net forum for how to modify your host file on your computer adding the domain website to block. this worked great. Then i went to a website such as vtunnel.com and was able to view the blocked website through it. So to still block it I need to add [url]... to the host site as well as any others?

View 2 RepliesI'm building an Expandable Groupbox control (source will be available in the codebank if I finish it), which is basically a groupbox with a [-] or [+] button to the left which allows the user to expand/contract it.
I've got it working pretty well, but now I want the user to be able to click the button in the designer to expand/contract the groupbox, rather than having to find the Expanded property in the property list every time. The ExpandableGroupbox control is just a UserControl with two panels (header and container), with an actual Button and a label for the text in the header panel. I know how to enable the user to click the button, even in the designer (this is done using WndMsg's and stuff, don't really understand that but it works!).
Now, there is one problem. When the button is clicked during design-time, the control is contracted (it's size changes), but the designer is not notified of this change. The selection rectangle remains as if the control size never changed, which is very confusing to the user. It only changes to the correct size after I select something else, and then select it again: At the moment, when the button is clicked it raises an event called Expand. I thought I could have my Designer class listen for that event, and refresh the selection service when it fires. I can get the control the designer is designing simply with the "Control" member.
Now here's the problem: Obviously I need to attach the Expand event using AddHandler, and I can see only one time to do that: in the constructor of the Designer.
So I tried it:
vb.net
Public Class ExpandableGroupboxDesigner
Inherits System.Windows.Forms.Design.ParentControlDesigner
Public Sub New()
[Code].....
1. Can you see any other way to listen for the event? There is no 'control initialized' event or something I can use where I can attach the event as far as I know.
2. How do I refresh the selection service in the first place??
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 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

I want to be able to reference an element in an array of structures by the name of the element in a visual basic 2010 function. For example
Public Structure myStruct
Public element1 as string
Public element2 as integer
Public element3 as boolean
[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.
HTML
<input type="text" id="id1" name="id1" value="myvalue" title="id1" >
How would I get "myvalue"? I've tried using .InnerText/.InnerHTML, but neither work. Instead of "myvalue" it will return "".

When I click button 1 for the first time I recieve the error "Object reference not set to an instance of an object." but when I click it the second time it returns the elements text perfectly.
I thought the wb.document element might not be instantiated so I've tried navigating to a page (google's homepage) before loading the page I want put with no success.
I also thought that maybe it wasn't giving the page time to load so I added the sub to deal with the documentCompleted event but this also returns nothing (though wb.document.url is set correctly to the webpage I want)
I was looking at a previous post and the poster was talking about htmlelement, so what I want to know is if you can use this function to find a html element on a wb page.I'm trying to make a program that will find the img src url for an image on a website and then return that url to the imagelocation of a picturebox.

View 3 RepliesI have the following code that adds the elements from between the <movie></movie> elements to a listview box.Private Sub ParseMovie(ByVal reader As XmlReader)
[Code]...
What I would like to do is make sure that it reads everything instead of using ReadToFollowing. I might add something else to the xml file, such as <release_date></release_date> and I want to make sure I don't have to edit the ParseMovie sub routine. I looked at the members of XmlReader, but I can't seem to get the right methods to do this efficiently. How should I parse every element between <movie></movie>.
Im trying to create an empty element in an xml file but still want to be able to close other elements without changing the empty element.What XMLTextWrite does to empty elements:
<Data>
<Feed>
<EmptyElement />
</Feed>
<Data>
When i use the text writer i cant use <writer>.StartEndElement() it starts to screw with my empty element. When im still having my program write inside feed. Here some code your you to drool over.
My example
Dim Settings As New XmlWriterSettings()
Settings.Indent = True

How do I check if an HTML element exists? This element will only "show" on a certain event. ex: numbers in a non-number textbox or something. I tried
If WebBrowser1.Document.GetElementsByName("ElementName")
But that won't work, because the element "is in" the HTML, even though the page doesn't show it yet.
Just like the title says, I have a webbrowser and I need to determine if the element exists or not before I invoke it.

Using VS 2008 and creating a style sheet in the Studio I noticed that when I wrote the word filter, it was not recognised by intellisence. Is there a bug in VS 2008? How can I make my app recognise filter? I really need to use this command word in order to render my transparency correctly
