Is there a way to check if an element is in the webbrowser1.document ?
I can click the button fine, IF the element is on the page, but sometimes i get to the end page, where i just have the "back" button, and no forward button.[code]...
How can you find a specific HTML element in a webbrowser.document? I'm making a program that will go to a specified address on the internet and find a html element and get the src link from the element then return the src to the imagelocation of a picturebox. Is this at least possible?
View 8 RepliesI'm writing out an XML file using VB.net. When I try to create another element to be written past the first, it errors out saying:
"Token StartElement in state EndRootElement would result in an invalid XML document. Make sure that the ConformanceLevel setting is set to ConformanceLevel.Fragment or ConformanceLevel.Auto if you want to write an XML fragment."
I'm not sure why it is doing this considering that the previous element has been closed. I tried to look for a writer.WriteEndRootElement, but I didn't see any in there. Any suggestions to get it to work?

The application I support is creating an amalgamted Word document by copying couple of Word documents in one document right after each other. The problem is the format of the some of the fields of the document that gets appended is changed in amalgamated document while the amalgamated document is the copy of AppendDocument (imagine if we have one document to copy in the amalgamated document)

I'm making my own ToDo program, and I need to add the ability for the user to create a ToDo item. When they do this, I need to be able to add in an XML element/section in a list file.My XML file looks like this:
<?xml version="1.0" encoding="utf-8"?>
<list>
<item>[code].....
Say if a user created an item with the name 'papers' and due date 'Tomorrow', I need to be able to make another list element like above and insert it before the </list> tag. Basically I'm asking how can I write to my XML file at a specific position (at the end before the </list> tag)? Is it possible just to go to the end of the file and go back a line?
I need to add some document management functionality into my software. Documents will be grouped by company name and project name. The folders need to be accessed by the application using the id numbers of clients/projects, but also easily browsed by the end user using windows explorer. Clients and Projects will be stored in a database. I am thinking of having the software create the folders using the friendly name and then using a hidden share with the id number for the software to access the files. [Code]
By using the hidden share, if the company name changes or its renamed for some reason it doesn't break the link in the application because its using the hidden shared based on the ID that never changes. Will having hundreds (maybe thousands) or hidden shares on a server provide a huge performance hit? Does any one have any suggestions or alternatives to provide this feature?

View 7 RepliesI have a number of rewrite rules for a lot of things that I did in IIS7, like removing trailing slashes, canonnical URLs, lowercase lettering, and such. IIS altered my web.config, and everything works fine on the website, like it should. But in the Visual Studio web.config, the opening < rewrite > statement is underlined in blue, and at the bottom of VS, it says that the element 'system.webServer' has invalid child element 'rewrite'. But this is how IIS made it. I didn't do this manually. Should I be concerned with this VS error, or should I just leave as be, since it's working how it should work? Here's an example of my web.config:

Is it possible to reference a structures element by the element's name in a similar way to that shown above. The code shown above does not work, as the expression obj(i).[elementName] does not work as hoped.

I have a function on my program that allows a user to load a listbox filled with words that are matched with words inside a databank. The databank is filled with 2 string arrays and file of .jpg Pictures. The Arrays attached to each word inside the listbox are approximately one page. Each page is two paragraphs of Text(string Array) and one Picture(20Kbytes).My problem is this. When the user selects the option print all, the listbox with approximately 10255 words is selected and begins to fill a Microsoft Word Document.Because the alotted amount of space needed for the MS Word Document is approximately 5 Gbytes,I need to open about 10 Documents and insert the String Array's and Pictures into each document one at a time.Is there anyway to check the filesize of the Open Document before saving the document.This way I could check the open document inside the algorithm for 512 Mbytes of memory and save the document before the size gets above 512 Mbytes.[code]
