I'm trying to load in a xml file that was build using another windows form, but when I try the xml document I get the following error: Name cannot begin with the '%' character, hexadecimal value 0x25. Line 10, position 13.[code]
View 3 RepliesI would like to add a XElement into an existing XElement as a child
Dim myDocument As New XDocument
myDocument.Declaration = New XDeclaration("1.0", "utf-8", "no")

What is the best way? There will be at least one rule but there could be as many as 4 total.
I am producing an XML file in my unit test using
Public Sub rssParserTest
Dim Const rssUri as String = "rssTestFile.xml"
Dim xmlFile = <rss version="2.0">

I want to remove the unit test dependency on a physical file and use a stream instead but my efforts so far have come to nought. (Is this best practise?)I am using NMock2 for mocking if I should be doing something with that.
i am downloading data from xml using linq library those data i want to add them on a textblock item
TextBlock1.Text = TextBlock1.Text & result
but it has an error :
Error 1 Operator '&' is not defined for types 'String' and 'System.Xml.Linq.XElement'.
When i am changing this line to :
TextBlock1.Text = TextBlock1.Text & result.Tostring
it works but it adds this data :
"<"data> data <"/data>
instead of :
hello
I'm working with a class that inherits the XElement class.The new class is called MXElement.It adds some new functionality to it for navigating through the XML tree, as well as some more information regarding attributes, but that's not particularly important.My problem is that I have an XML Tree filled with XElement objects.However, when I create a new MXElement object from the XElement object before, it is just a copy of that object. This means that any changes that I make to this object will not effect the original tree.I suppose what I'm asking for is a way to build in the functionality for my MXElement class and keep references to the original XElement objects.If possible, I would really prefer to keep MXElement a child class instead of building a lot of extension methods for XElement.
View 1 RepliesI am using XElement to manipulate my xml file: to find target node and then add child node to it. But now I have one problem. Let's say my xml file looks like this:
<Report xmlns="MY_NAMESPACE"
<Width>100</Width>
<Height>100</Height>
[Code].....
The second <ReportItem> is the newly-added one, but sadly this is not a valid file (my parser is complaining in the further processing of xml file). So how can I make this new item look exactly like the existing one, without any namespace? This has been driving me crazy. I spent a whole day to figure out that I need to add the curly brackets so that it will find the target node (it doesn't work like what the link above says that it adds and searches the default NS automatically), but now it adds something unnecessary?
I'm trying figure out if this is possible. Basically, I need to create an XElement and then add one or more siblings to that XElement, but without a parent. I'll add that list of XElements to a Parent later, but need some flexibility in building this and other lists of XElements before doing so. Is this possible?
So I would have something like:
Public items As XElement = <ItemA>Something</ItemA>
And then I need to add an element so that the result looks like:
<ItemA>Something</ItemA>
<ItemB>Something Else</ItemB>
That result is what I need to pass around as a single object. I've messed arounnd with IEnumerable(Of XElement), but there is no .Add.
I'm building XML based on some data pulled from a database, and thought to try building the XML with LINQ2XML. The data is coming from a few different places, so I've been building the XML by sections, based on what I have populated in DataTable objects. Using the XElements and XAttributes, I can get one or the other, but I was wondering if anyone had insight in how to make the determination of whether to use XElement or XAttribute at the point where the XML is being built.[code]So it's in that LINQ query that I need to determine if ValueToParse, for example, has a valid value (non-empty). If it does, then I can add the node and it's value. If it DOES NOT, I need to add that named node, but with an attribute of 'xsi:nil="true"',The caveats are that that there are some descendants which repeat over different parents (for example, there's an AddressDetails section which contains AddressDetail elements. These AddressDetail elements can contain 0 or 1 Contacts groups of Contact elements, so adding a node to the Contacts node isn't a straightforward option as it would be if there was only ONE Contacts element).I don't usually USE LINQ, but it SEEMED like a good idea at the time XD
View 1 RepliesSo I wanted to check when last a table was changed, and I basically came up with this query:
SELECT DB_name(database_id) as [Database],OBJECT_NAME(object_id ,database_id) AS DatabaseName, last_user_update
FROM sys.dm_db_index_usage_stats
where DB_name(database_id) = 'Database Name'
Now what I want to do is put this in my code using LINQ. I have added the view to my datacontext and all that good stuff, but I don't really know how to do the SQL built in functions DB_Name and OBJECT_Name. I realise that I could do some sort of join to get the values for the id's instead, but I don't know which views I can find the database name and object name in.
Is there a linq equivalent to these functions? Alternatively, what are the system tables/views I need to look at to convert these ID's into their respective names?
I´m gettin the error Calling the fuction GetListItems but is kind weird because it works in Visual Studio 2008 Express but no in Visual Basic 2010 Express:

[code] What I want to know is, if this is the right way to load an XML of a server, If yes, How do I handle exceptions like "Server Error 500" etc.I also want a nice little progress bar to show the user that the XML is being loaded of the server, How do I change the responseTimeOut.If No, How do I load an XML of a server??
View 4 RepliesI am trying to parse incoming data from a serial port that appears to be XML format but an exception is thrown when I switch from a simulated setup to the real deal.My program runs great in a simulated setup but when I try it out on the real device I get: XmlException was unhandled Unexpected end of file has occurred. The following elements are not closed: li840 line 1, position 9.The li840 tag is my root tag and the position never seems to get past 40. I've tried using a try catch block but in my in both my simulated and real setups my values are blank but the program will run without exceptions. Should I take my received data and put it into a file and then read from the file? or is there something else I can do to make this work properly? [code]
View 12 RepliesI need to get the url of the webpage the webbrowser is navigating to, but since the code executes faster than the webbrowser navigates to the webpage, it gets the url of the last page. I cant use DocumentComplete Event because i have a tabbed browser,
and i cant write events because im creating tabs(with webbrowsers) at run-time. So how would i check to see if the webbrowser has loaded a document?
How do i do that ? I want to wait until the webbrowser has loaded the document and then add the document text to a textbox... How do I do that ?

View 4 RepliesI am pretty confused about lambdas. What I am trying to do here is write a function that will return an object from a certain table with a certain criteria. So lets say I can write:
function GetRecord(TableName as string,Criteria as string) as object
'do the linq-stuff
end function
Now I don't care if the parameters are strings or lambdas or whatever, but the end result must be that at runtime I don't know which table and which criteria will be used. As sometimes I need to get a customer record by email and sometimes a product by id etc. If possible I would prefer returning a list of matching objects and then I would just use .firstordefault when I want 1 (such as by id...).

I have "added an existing project" to my solution. This item has been used in several different solutions but I am running into an issue for the 1st time w/ it.
I have 2 applications:
X & Y
I copied the "existing project" from the X folder to the Y folder (so I would not be altering the same "existing project". Then I "added" the project from the new Y location. I also added reference to the DLL file in location Y. However when I debug from program Y it keeps running the code from location X. Everything that I know to look at looks correct. Any ideas on what is causing the issue and how to resolve it?
FYI, To prove the point I changed the folder name for testing in the X folder. When I then debug program Y i get this error:
Source file: C:VB_FIlesYY"ExistingLibrary""Existing".vb
Module: C:VB_FilesYYinRelease"ExistingLibrary".dll
Process: [4416] Y.vshost.exe
The source file is different from when the module was built. Would you like the debugger to use it anyway?
When I start the debugger,there is a message that contain the source file is different from when the module was built. would you like the debugger to use it anyway? how to solve that thing? and also, i can not use the breakpoint there is a sign like triangle and "!" and it says that"the breakpoint will not currently be hit. the source code is different from the original version."

View 2 RepliesI am working on a vb forms application in VS2008.What I am looking to do is have 3 file managers on the form.The top is the source where files can be copied to the 2 other file managers.What I have been looking for is an example of the file explorer so I can modify it.So far I have been unsuccessful in finding a good example so I am here to ask the experts.So the gist is the first file explorer will allow a user to connect to thier local hard drive.The other two file explorers would allow the user to connect to two different servers through entering the path they want to view those file trees.After that the user could click on the file they want to copy and then hit a button for example and the file would be copied from the local to the two other areas.Would it be easier to just use text boxes with a confirmation that the files are being copied?Or can a full file manager be built to drag and drop files?

PS Using Visual Basic 2008 on Vista64.
I have an XML file I need to parse, but only for the text, not the HTML. Here's an example of a node:
<highlights><![CDATA[<ul style="color:#000000;font-size:small;font-family:verdana,geneva,sans-serif"><li>Classy & elegant purse hooks</li><li>Choose from various styles<br></li><li>Stable and reliable</li><li>Makes a great gift! </li></ul> ]]></highlights>
As you can see, the CDATA has HTML code in it, so when I do element.Value I also get the tags. Is there any simple way to get just the text?
Im trying to add a Xelement to an XElement. But when I tried to add this XElement to the empty XElement VB throws "Object reference not set to an instance of an object" The Bold line code throws the exception

I have an XElement and an XPath expression that selects a node from it. It works fine in the original program that I wrote it in but doesnt work if I paste it to another program. I've checked the references and import statements.
I think the problem might be that the original program had the code within the class of a wpf window while it was moved to a abstract class where it doesnt work.[code...]
