How To Set Attribute Value Of 'A' Tag In Live HTMLDocument With Quotes Around It
Feb 10, 2012
Bascially, all i'm trying to do is change the value of an attribute (such as the TARGET attribute of an A anchor tag) to "_TOP" if the attribute exists, if it doesn't exist, (if IsNull returns True) then I just create the attribute and set the value to "_TOP".The problem is, it almost always sets it without quotes around it, and even if i try to set it with quotes by setting .value = Chr(34) & "_TOP" & Chr(34) then what it does is it sets SINGLE QUOTES around the quotes I place (it's like a bad joke) and turns up in the HTML as '"_TOP"' (lol), and if I set it normally, its just saved as <a href="..." target=_TOP>some link</a> (without quotes).[code]I've changed the above variable names & turned vars into strings ("target") etc to make it easier to read for anyone reading.
I have wasted heaps of hours on this, MSDN docs are as usual horrid, there is no real documentation or tutorial on this stuff either. I've even tried using .nodeValue instead of .value to do the setting, but makes no difference. Also, I've tried (in the Else section) removing the attribute and re-creating + re-adding it from scratch to see if this would make a difference, but it didn't.Of course, quotes are important because if you try to perform an action (call a method) on this element or use it later, you will get the dreaded "unspecified error". I do this through the WebBrowser Control in VB6, but same principle should apply everywhere... C#/.NET/JavaScript etc as it seems to be DOM related).since posting we realized that if we pass the attribute name in uppercase, then the value is saved with double quotes around it. although this is not a real solution (just a temporary one), i am still looking for answers if anyone has one and accepting any thoughts you may have about this in this post. However, the temporary solution has created another sub question, being a post about the problems that arise from using this temporary solution. The sub question related to this temporary solution is located at the following link for those who may find it useful or interesting to read about, and for those who would like to contribute to this discussion further: Must pass uppercase to set MSHTML element attribute (.setAttribute) correctly, why? And CaseInsensitive .setAttribute doesn't work
Is there any way to use selectnode with the attribute having both single and double quotes? If we are having single quote in the attribute we can use like below,
This should create a desktop shortcut but instead it spits out an error that is because of the quotes inside quotes. They need to be there, I know this is the problem as I have tried without them and it has worked. Another problem though is that it creates the shortcut (when Idon'thave quotes in quotes) but wraps the whole TargetPath in quotes making the shortcut unusable. Here is my code:
Dim input As String Dim s As String = Environment.GetEnvironmentVariable("UserProfile") input = TextBox1.Text
I get an error when I try to build my project.'SSLAccessFiltercannot' be used as an attribute because it does not inherit from 'System.Attribute'. [code]
In my project i want to search a word in 10 different music sites and return all the links on the site, the problem is that i can't convert a string to a htmldocument.[code]
I would like to read a file from disk ( TEMP.HTM ) and convert it to a System.Windows.Forms.HTMLDocument.I know that I can set a WebBrowser control to Navigate to the file and then get its .Document property, but is there a better way, possibly using something in the System.IO.File space?
I want to make a database of all the xbox live arcade arcade games on the xbox live marketplace, I need to parse an xml file and add the needed data from the xml node into a datagridview.Here is the xml file i need to use to grab links and other data about the game:
[URL]
Being the noob I am it took me about 6 hours to figure out how xml works and to write some code for what i need to do.
Here is what i came up with:
'for grabbing the name of the update Public Sub updatename() Dim xmldoc As New XmlDataDocument()
[code]....
That code works fine.Now when i add another column to the datagridview called "update size" i want to know how to add the grabbed data from another sub i made to the new column.What would the code be for adding the strings for the new sub into the seconds column? the first was, DataGridView1.Rows.Add(str)" . So what would the second be ?Also another question i have is how do i put an image in an imagecolumn by a web link, not a local picture.
I have one sample project to automate Internet explorer in VB 6.0. The same thing when I am trying to do with .Net its just hangs my Internet explorer document. I am not able to type or click on any control on the page.
Here is the sample code block.
[Code].....
Even i am not able to fire any htmdoc_focusin or focusout of DOM which was really easily accessible from my VB code.
I'm trying to write a function that can retrieve all the links from a webpage. I'd like to send only a string containing the URL. Basically, given a string of a URL, I'd like to "load" that into an HTMLDocument so I can access the Links collection. I just can't figure out that part.I've already written the function by using the Document in a WebBrowser. But, after selecting a link, I'd like to get its links, and so, and so on....while the user is still browsing the first page.
I'm able to retrieve the source code of a web page and store it in a string variable. I would like to cast that string variable into an HTMLDocument if possible, to make parsing its elements much easier.
This line is throwing the error; Public WithEvents CurrentDoc As mshtml.HTMLDocument Researching the error tells me that HTMLDocument isn't fully qualified. Isn't this fully qualified? If I change it to Microsoft.mshtml.HTMLDocument then it says it's not defined.
I know that I can select an option in a listbox within my HTMLDocument (which refers to a webbrowser control's HTMLDocument) using SetAttribute. For example:
However, I can't figure out how I can select multiple items within the listbox. When I call SetAttribute repeatedly, it always unselects the old one first.
I was trying to use HtmlDocument and a given url to pull in the html contents of a website to use. However there is no constructor for HtmlDocument and it's Url property is readonly. Is there any way to create an object that contains the entire DOM for a given url?
I need to Read a HTML File and retrieve Tag value and attribute value.In HTMLDocument there is no LOAD function to load a html file,but there are methods like getElementByTagName.How to load a html file in htmldocument class?
Is it possible to load HTML content into the HTMLDocument object without having to use the WebBrowser control? I have an html file stored locally that I want to parse in order to find out which checkboxes are on and which are off.
All of the examples I've found use the Webrowser. It just seems convoluted to have to use the WebBrowser in order to get to a DOM object.
I have a page to which i send some variables with the GET method. In my VB back-end i get those variables using Page.Request.QueryString("<name>")If i then use the IsNumeric method to make shure it is an numeric string i get True back as value.
When i then try to transform the string to an Integer using val, cìnt, Integer.Parse or cType I get an error saying that my string could not be converted to a integer.So i made an error page which gives me all the info i need to deal with the problem (view below) Exception Message: Conversion from string "" to type 'Integer' is not valid.
[Code]...
IsNumeric confirms that it is a numeric string and that it should be convertable to an Integer. So why won't it work. I don't think that my code should provide any extra information because it only gets the querystrings, uses IsNumeric and then tries to convert them.
I have a xls file, or a csv without quotes, and using vb.net need to turn it into a csv with quotes around every cell. If I open the xls/csv without quotes in MS Access, set every column to text and then export it, its in the format I need. Is there an easier way? If not, how do I do replicate this in vb.net?
I have a string like this:This <span class="highlight">is</span> a very "nice" day!What should my RegEx-pattern in VB look like, to find the quotes within the tag? I want to replace it with something...This <span class=^highlight^>is</span> a very "nice" day!Something like <(")[^>]+> doesn't work :(
This form works in VB .NET sendMsg = "<CStatus timestamp=""0"" " & _ "type=""login"" " & _ "cid = """ & cID & """ " & _ "key=""" & loginKey & """ />"
But I can't get it work in C# sendMsg = "<CStatus timestamp="0" type="login" cid="" + cID + "" key="" + loginKey + "" />";
It does not give the same effect. I want this as an output: <CStatus timestamp="0" type="login" cid="var_cid" key="var_key"/>; Is there any stringXml command in C# or another way to use double quotes in string? Solved it with XmlTextWriter
EG: i have 5 quotes listed 1 to 5, and i want some code to generate a number 1 to 5 and the label1.text = "chosen number"i cant for the life of me work it out, i think it was dblrnd
ive been working on a little program last days, it''s finished i can get it up and running it does all it has to do. the only thing im running to is that i want to write lines to a text file... which works.but in this text there are double quotes so i''m having this:
Dim folder As String folder = Form1.FolderBrowserDialog1.SelectedPath For Each foundDirectory As String In My.Computer.FileSystem.GetDirectories(folder + "\players\profiles\", FileIO.SearchOption.SearchTopLevelOnly, "*")
I'm using some code to read a text file line by line, the thing is it can contain speech (or double) quotes in the line of text, is the a way of getting rid of them, I've an example line from the text file below.
Suppose I have a text string like this.. <The dog needs to go out "">
In the event the string ends with "">, I would like to isolate it. The end goal is to only write out text that looks like this: <The dog needs to go out "now">, where a value exists between the quotes.
Here's my code: If chk = "" Then I've tried nesting chr(34)'s around it and all kinds of other things. I just cannot seem to interpret the quotes. Basically, I am appending an XML file from a database.
Code: Private Sub AppendFile(ByVal textFileDirectory As String, ByVal textFileFile As String, ByVal textStringToPass As String) Debug.WriteLine("textStringToPass: " & textStringToPass) ' If the last two characters of the string are "" then skip Dim a As Integer = Len(textStringToPass) - 1 [Code] .....
