View 12 RepliesI'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.
View 5 RepliesI'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.
View 4 RepliesI 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?
View 2 RepliesBascially, 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
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.

Even i am not able to fire any htmdoc_focusin or focusout of DOM which was really easily accessible from my VB code.
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:
htDoc.GetElementById("lstCountries").SetAttribute("value", "88")
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?

View 5 RepliesIs 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'd like to convert a string which contains a decimal number into string that contains the binary value, the octal and the hexadecimal value of that decimal number.Afterwards I also like to convert a string containing a binary, octal and hexd. number into a decimal string.Basically I'm looking for the functions:
dec2bin
dec2oct
dec2hex
bin2dec
oct2dec
hex2dec
I'd not prefer to rewrite a function, I'm sure the framework must have these functions already.

I'm also pulling info from the bios, disk drives, video, etc. What I've noticed, is although it runs fine on my pc, it may error out on some pcs since it is hardware dependent.I'm having trouble implementing a check to find if it exists before I convert to a string and add it to my overall string.
I'm working on a mass text replacer program because I'm sick of all the 10-day trial ones out there that aren't very good.The entire program is basically finished (All easy stuff), but now I need to code the actual replace/delete stuff, which I'm stuck on because apparently the way I originally intended to do it is not possible.
The way it works is you load a text file (.txt, .cfg, .ini, .doc, etc.) which opens a StreamReader which writes all the data into a listbox. Then you pick whether you want to replace or delete a string. If you select replace, then you enter the string to search for and in another textbox you enter the string to replace it with.
The way I originally intended to do this was like this:
If o1.Text = "Replace" Then 'The option
Replace(txtfile, str1, a1) 'txtfile is the data, str1 is the string to find and a1 is the replacement
End If
The problem is, I believe this method requires txtfile, str1 and a1 to be strings, but they're all 1-dimensional string arrays, which cannot be converted to strings, or at least I don't know how to convert them.
A friend told me one way I could do this is to open both a StreamReader and StreamWriter and do the replace/delete line by line as they are entered into the memory and write them to a temporary file which is then copied over the original. I can do this kind of, but I still don't know the proper way of doing the actual replace code because the string to find and the string to replace with are still 1-dimensional string arrays rather than strings.

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.
Value of type 'System.Func(Of String, String)' cannot be converted to 'System.Converter(Of String, String)
Why? They are both effectively a function pointer (or delegate?) to a function that accept a string and return a string.
I have 1 string of 12 numbers separated by a ',' "11.11,22.22,33.33" etc coming in my serial port. One number has so far been 5339, but now its changed to 533d, which causes problems, for reasons I am still trying to work out.
The top numbers are all real numbers ie 0.000 or 00.00 or 000.0, whereas the bottom 3 numbers are Hex FFFFF but just happen to show decimal numbers by 'good luck'.[code]....
