C# - HTMLAgilityPack And Timeouts On Load
May 3, 2011I'm using HTMLAgilityPack in a parser that I have up on a server, but I'm having issues with one of the websites that I'm parsing: Every day around 6am they tend to shut down their servers for maintenance, which throws off the Load() method for HTMLWeb, and makes my app crash. Do any of you guys have a more secure way of loading a website into HTMLAgilityPack, or maybe some way to do error checking in C# to prevent my app from crashing? (my c# is a little rusty). Here is my code right now:
HtmlWeb webGet = new HtmlWeb();
HtmlDocument document = webGet.Load(dealsiteLink); //The Load() method here stalls the program because it takes 1 or 2 minutes before it realizes the website is down
.net - Using HTMLAgilityPack To Parse An HTML String Not From A URL?
Feb 5, 2012I am trying to take a string that I have marked up through vb.net code and cross-check it with the text file it came from originally. This is for proofreading the html output.To do this, I need to parse an HTML snippet that does not come from a URL.The examples of HTMLAgilityPack I have seen get their input from a URL. Is there a way to parse a string of marked-up text that does not include a header or similar parts of a well-formed webpage?

Parsing - Preventing Errors With HTMLAgilitypack
Dec 26, 2010I'm using the HTMLAgilityPack to parse HTML pages. However at some point I try to parse wrong data (in this specific case an image), which ofc fails for obvious reasons. Code:
How to check whether the content is 'parse-able' before trying to parse it to prevent the error? For now it is an image which makes an error popup however I think it might be just anything which isn't (x)html.

VB 2010 + HTMLAgilityPack + Large Processing = Error?
May 22, 2012I have spent way too much time trying to sort this little issue out. I have narrowed down the issue to the exact procedure that throws the error. Yes, I have used Google..
Try
Dim tempSource as String = Nothing
Console.WriteLine("Loading document...")
[code]....
I am loading a text file, that contains about 1100 lines, and each line is going to be processed with HTML Agility Pack. From what I can tell, when it runs "doc.loadhtml(richtextbox1)", it throws the error. I also have tried to load the file into a string, and load the string with "doc.loadhtml(thestring)". It doesn't make a difference, still errors.
Here are is a sample of how each line looks:
<Site Index="" Name="" Group="" PR="" />
<Site Index="" Name="" Group="" PR="" />
[code]....
I am using HTML Agility Pack, however the above is what is on every line, about 1100 lines! For testing, I have a smaller text file made of about 50 lines before I load up the 1100 line file ;) There aren't any HTML, HEAD, or BODY tags! They aren't needed for my parsing. I am using HTML Agility Pack because it is easy to parse elements with. I can grab each value easily from each line.
I am not sure if maybe the error is because it technically isn't HTML? Meaning since the loaded code doesn't have an HTML or BODY tag, that it errors? I wanted to get this question posted, and while I am waiting on some answers, I am going to parse the document another way. Just curious as to what the deal is and why HTML Agility Pack isn't working. More of a proof of concept then anything, for my own learning and knowledge.
Here is the error I get (btw the on the doc.load() line, is where it throws the exception):
Object reference not set to an instance of an object
Last Note: The routine is on a background thread. I have used multi-threading before, and have delegates created for deeper in the code.

MsgBox Interfering With Array?
Aug 6, 2009I've built a quiz program that uses several arrays to store questions and answers. For debugging purposes I've inserted several msgboxes, when I remove them I get the same question in all of the question slots(same with answers) I spent a lengthy amount of time googling, and decided I needed to post.
Form2_load calls generateQuestion. If the msgbox is inside generateQuestion, the program works, if it is right after generateQuestion it works.

Scripting Is Interfering With Main Application?

Another OPTIMIZING Macro Vba Code For Excel 2007 - The Code Is A Sort Of Transposer For Data
Sep 9, 2011this code was not done by me originally and there are some thigns here i dont quite understand i have altered it a bit from my coworkers code to suit my data and it works. but too slow. and when i have 4000+kb excel files it might freeze altogether. ( I have checked tho that when and after this transposer runs it will still be within the excel row limit, i had done calculations before and made a macro to automatically split excel files based on number of columns and rows to make sure this is so ). This code seems to start out fast then goes slower the longer it runs. at least this is what it seems liek to me.
