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?

View 1 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

View 12 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 5 RepliesThis 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.
[Code]...
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.
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.

View 4 RepliesI am trying to create a log file which I am going to use to populate some controls (DataGridView or Treeview). I am trying to figure out if should use text files or XML files to do so. Effectively the log will highlight multiple phases in a client-side app. The log will be written to at various phases when the project is running. The user will always have the options move on to the next phase or save progress and exit the project. As such, I want the log file to highlight how far the user has progressed throught the various phases AND I want the log to highlight varous information from each phase. Whenever the user starts the project, they will be given the option to load existing log files. So the project will have to read these log files and append them where necessary as the user progresses.
I am not sure what the best way to do this is and below is a rudimentary approach using text files. As you can see, the top of the file would have a summary of all the phases and whether or not the user completed each phase. Next each phase would have a data section highlighting what data was stored along the way. I have used a ":" to denote each section. Then within each section I would obviously need to use a delimeter for all my data. So if Phase1 = True, then I would load all the pertinent data from "Phase1:" into the desired control. Can anyone provide an efficient way of doing this and provide some insight as to whether I should use XML instead. The phases my change during development and I am not sure yet which controls I will be using. Does XML provide more flexibility.
In summary I am looking to create, read/write and append log files and populate controls with the data in varous sections of the log file. Example:
Phase1 = True
Phase2 = True
Phase3 = False
Phase4 = False

View 2 RepliesI have to generate an XML file from several database tables. I could use the WriteXml method of the DataSet to do it, but the database tables are really huge and I can't add all those tables in the DataSet at the same time or it may cause a problem because of the big amount of memory used. Then I decided to use the DataTable's WriteXml method and save table after table, but the the generated file only stores the information of the last DataTable.WriteXml's call. How can I preserve the previous XML data when adding all that information?
