I'm working on a .NET application (VB 2008) that gets all of its data from a web-based Django application.I'm using Linq-to-XML and Linq-to-objects in the app.One API call is giving me XML data in the following format that I am loading into an XDocument.
[Code]...
I have a program, and a string is generated. something like:
TAG POS=1 TYPE=INPUT:TEXT FORM=NAME:NoFormName ATTR=NAME:movie_imdb CONTENT= [URL]
TAG POS=1 TYPE=INPUT:TEXT FORM=NAME:NoFormName ATTR=NAME:movie_urls[] CONTENT=[URL]
Now I need this to be:
TAG POS=1 TYPE=INPUT:TEXT FORM=NAME:NoFormName ATTR=NAME:movie_imdb CONTENT=[URL]
TAG POS=1 TYPE=INPUT:TEXT FORM=NAME:NoFormName ATTR=NAME:movie_urls[] CONTENT=[URL]
v=ACFXQPGT
I know this might look easy, but I already trid so much but it doesn't work.
Now I was trying a regex:
Dim pattern As String = "CONTENT=|?http"
For Each m As Match In Regex.Matches(Data, pattern)
MsgBox(m)
Next
But I don't know what the "|?" or pattern should be.
some of the xelements within the query were calling for tags that didn't exist in the original xml, heres a simple example of what i mean.
element = _
<xml>
<object>
<string>someString</string>
[code]....
So how do i change the querry so that it wont produce a null error if the tags asked for are not present.
I've become undone when trying to convert xml linq query result to a datagridview (see code below), needing some pointers,.

How can i replace selected cells in a datagridview by using copy and paste or some other method. I want to highlight a Row or Column and then replace all the highlighted cells with one value
View 3 RepliesLet's say I have regular string called tempstring, and I want to change a specific item in that string. Like if tempstring = ";1;2;3" and I want to change the "2" to "Baboon." Here's my best solution on how to do it:
vb
Tempstring = ";1;2;3"
'Datasplit tempstring
Dim datasplit As String() = Tempstring.Split(New Char() {";"c})
[Code]....
This works, however, it feels a little heavy. Is there an easier way to do this? Perhaps a way to directly replace datasplits without readding them all to another string one by one using a loop?
I am needing to open up a file, it is a kml file, and I am wanting to search for a particular line and the replace some of the lines following that.
Dim file As New System.IO.FileStream(kmlFileName, FileMode.Open, FileAccess.ReadWrite)But I don't see any means in which to actually go through the file line by line in order to search for my criteria.
I need to add some information to a PDF (Trim Box proporties, actually replace Media Box proporties with Media Box and Trim Box proporties), and I dont have the support in my PDF-motor. So I found out that I can use Notepad++ to open the PDF as a text file and simply add the Trim Box properties as a string and save it. Now I want to do it automatically with vb.net. When I use Stream Reader/Writer the PDF gets destroyed and loses information (Stream Reader dont read all the NUL, SOH, STX etc. I guess). I tried to read the PDF using ReadAllBytes/WriteAllBytes and then it works good, but then I don't know how to replace "Media Box ..." with "Media Box.Trim Box.". I try to use IndexOf but I can only search for single Byte not the whole string. I'm not good in binary and thats perhaps the problem :-). Does anyone have a better way doing it or how do I search for my string "Media Box" in binary?

It is easy for me do in database table, This is run time and i need to work in RAM. how i can build the array and pull the data accordingly.
how to search XML trees with LINQ using VB.net. I've found some very helpful posts for C#, but none for VB.net?How would I use LINQ to XML to get the value from example XML Getting a set of elements using linq How to get elements value with Linq To XML I want to get the inputlocation for the process where name = "MyProcess1" Based on the example links above, I have been trying code like this:
Dim inputLocation As String = xdocument.Descendants("Configurations").Descendants("process").First(Function(c) c.Element("name").Value = "MyProcess1").Element("inputLocation").Value
But the code is not returning any values. here is the xml
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

I would like to get the first N groups elements with Linq of a ObservableCollection, an example trying to get the first 2 groups:

I have this XML
<?xml version="1.0" encoding="utf-8"?>
<root>
<xsd:schema id="root" xmlns="" xmlns:xsd="[URL]" xmlns:msdata="urn:schemas-microsoft-com:xml-msdata">
<xsd:import namespace="[URL]" />

And I also have this method, where I take two files and take some values from them, and then I merge all the values into an object in the second query:
Public Shared Function RetrieveTranslation(ByVal filefrom As String, ByVal fileto As String) As List(Of clsTranslation)
Dim valuefrom = (From l In XElement.Load(fileto).Elements("data") Select l.Element("value").Value).FirstOrDefault
[Code] .....
So, the problem is that when I run the code, there is an "Sequence contains no elements" error in the first query(valuefrom). I debugged and it says that there is nothing in the query, but I don't understand why? I'm curious to know if it is well done to do something like I did, create an object from two queries, putting the first value in the second query.

I want to create a file upload client for uploading.com and I wanted to know if it is possible to make an application that lets you select a file from your hard drive, press an upload button and then the app will process it just like the website processes the file when you use a browser.Also I want the app to display the progress bar that the website displays when you upload, and when it's done, it has to get the URL for the uploaded file and display it in a textbox.Why not just use the website you ask? Well, I'm planning to make this into a bigger app but nothing will really work unless I get this to work first, so I have to start here.
View 1 RepliesI've been working on this RegEx for the past day or so and I think I have it worked out so that it returns the data I want. First a little background.I have a content editor that users will be able to edit web pages. They can format text, add links, etc.. standard content editor stuff. When they click save, the editor provides the ability to get the content (editor.Content) and put it into a string. What I want to do is get any links (<a> tags) and find out if they are internal or external links and if they are PDF files.
Here is the Expression I've come up with:
<a[^<>]*hrefs*=s*[""'](?<domain>https?://[^/s'""]*)*/?(?<path>/?[^s""]+?)?[[>""']
With this, I am able to separate the domain (if it has one) and the path out. Then, I loop through the matches...
dim matchColl as MatchCollection = Regex.Matches(editorContent, regExString)
For Each m as Match in matchColl
If m.Groups("domain").value <> myInternalDomain and m.Groups("domain").value <> "" then
'this is an external domain... do some stuff
[code]....
My question is this... the parts where I 'do some stuff' to the values, what would be the best way to get that back into my 'editorContent' string? I could probably put the editorContent into a StringBuilder and do a whole bunch of replaces on it, but is that very efficient?So, for example, with the PDF, I want to specify that it open in a new window (target="_blank") and for the external URL, add some javascript code into the onclick attribute.
Is there any way to use a LINQ to XML to query an XML document like the one below to create new (anonymous or strongly typed) objects from the child elements of a descendant? Here is my XML document:

I've been seeing a lot of people reference getting HTML elements using the web browser control. And it seems to be something I may want to utilize in a program of mine.
a program which will get the html of an imageboard and check for updates, without loading any content other than the html (thus saving bandwidth). I've checked and this is not against any TOS.
But here's the thing, I don't want to actually navigate to the web page, because that'll load everything anyways. Is there a way I can search for HTML elements (and get their content) without actually "running" the page (for lack of a better word).
I am attempting to consume my Zenfolio RSS feed so that i can display the images in the feed. How can i access the url value of the media:thumbnail and media:content elements in my RSS feed?

Is it possible to replace the selected NumericUpDown controls with ComboBoxes?
I understand that not all properties can be conserved but the only properties I need are the location and the size. The workflow I have in mind is as follows:
Select certain NumericUpDowns Click replace with... and then select ComboBoxes (or any other approach) Where the NumericUpDowns were, there are now ComboBoxes of the same size
The reason I want to do this is that I have to put together a GUI with multiple tabs. Each tab page has a list of Labels with either NumericUpDowns or ControlBoxes next to it. The order of the controls changes per tab. I just want to copy the items on the first tab and paste them on the other tabs. Then per tab I only have to change certain NumericUpDowns into ComboBoxes.
Replacing selected ONLY text in a string
View 3 RepliesI am selecting text using SelectText method in my string.I want to replace this text but only the selected area. When I use Replace method, it replaces all words in the string. (e.g This Computer is a good Computer. I only selected last Computer and want to say, This computer is a goods machine.)
