I'm trying to make an app that will scrape numbers off of a webpage. What I want to do is have it read the Game Name and then Views (for statistics keeping). The WebPage is set up like
<tr class="odd">
here are 7 <td> tags that display different things
</tr>
[Code]....
I'd like the app to check the second TD tag to see if it's innertext says, lets say, 'GAME', and then if it does, it adds the innertext of the 7th TD tag (which is a number), to the total sum, and it scrapes all of that info off the page.
I can understand the logic of how to process the info, but I have no clue as to reading the correct tags.
Im trying to scrape some text on a webpage, I asked in the regex section and they recommended to use HtmlAgilityPack with Xpath to scrape the info I want.
I am *VERY* new to web-scraping and am trying to scrape some information off of a webpage that is heavily javascript enabled. An example of the page I am trying to scrape from is: [URL] I am trying to scrape the property links such as "322 E 98th St" The text appears on the webpage and I can find the link myself, but it doesn't appear in the page source code.
I am trying to scrape it using the webbrowser control using the WebBrowser1.DocumentText property, but it doesn't even show the links simply when I view the source in ie. I am sure this has something to do with the javascript it uses to load up the page or maybe iFrames,
Ok so basically heres what i need to do: Extract text from the webpage that meets a certain criteria. There will be a ton of these on 1 page and i would like to add them to a rich textbox on sperate lines.
I know that it needs to be in a loop and its needs to Parse the wepage(Dim web1 As String = Me.WebBrowser1.Document.Body.InnerText)
The criteria is: Starts with 1 to 4(random) integers, Followed by "my" then 13(random) numbers and letters. Or if it starts with "167my" + 6(random) number and letters.
Edit: Also im going to try to make it loop through a list of webpages to do this.
I'm trying to make a small scraper can't figure out how what i want to do is scrape the <a href over the webpage I just navigated with webbrowser1.navigate now there are many <a href over the page i need to scrape all the <a href only this ones:
i need the code between "<a href=" and "><img is there a command to find a string in html after <a href=" and before "><img ? scrape all of them there are many and save it over txt file how can i do that?
I'm just starting working on a program and the amount of pages I'm trying to screen scrape take over 20 minutes, so I was hoping I could run like 4 or 5 threads to cut that down??? I'm pretty much still a novice, so be easy on me. I understand good, though.
I am developing a web program using asp.net(vb) that scrapes data of a certain website. I am using System.Net.HttpWebRequest and System.Net.HttpWebResponse.My problem is I can not retrieve the codes of certain frame/container where the data that I needed is located. I mean, when I view the source code of the website, I can not find the data but I can see it on the web page. When I view source it, it is under the
I am using a for next loop to scrape through some html code. I am testing elements for a certain string, and when it hits that, I need to get the string that resides 2 elements earlier.When going through a for...next loop (I know you can loop completely backwards with step -1), is there a way to 'go back' 2 loops? Ex)for each'lets say we are 5 loops in and our if returns true'can i go back to loop 3, perform an action, then return to loop 5 and continue the real loops?

I just got VB and I am having a hard time learning this stuff. but I am not giving up.I am looking to make a web text scraper, so I can scrape words off of webpages and put them into a text file.I couldnt find a whole lot of help in the search function. bare with me, I am new here and new to programing also.
see this codes scrapes all href links and check if it contains "/file/" to save it but I get duplicate links saved so If i can change this code to work some how with Innertext("More") I will have no duplicatestried to configure it to work with innertext it just doesn't fit the way I think it should ;/and if anyone can add how can I remove duplicated urls on my txt file that would be really nice I might need it
Dim links As System.Windows.Forms.HtmlElementCollection Dim b As String links = WebBrowser1.Document.Links
I have used Web Browser in VB to get the HTML source code of a web page and put it in a richtextbox. I need to take that HTML and extract the data needed from it. I have searched and cant find an example that I can understand being new to VB.Net I am trying eventually import the data into excel.
i have an aspx page with vb.net back end. in that page i get names and url's from the database depending on different conditions. My requirement is that when i get the url, the code should then use that url and have that webpage in a small preview form on my existing aspx page. so basically i have a table as follows -
I making a webpage with the help visual basic. I wanted to put a flv video in it and i used flash control for asp.net [URL]. I made the player in flash told it to download the video from the sever. Now when i put the player on the webpage and put the webpage on the sever it cant play the video. But when i just pres the the player which is in swf format it works. It can download the video. But when i put the player on my webpage it cant.
I have six textboxes, and upon button press it randomly generates six numbers, one in eact text box e.g. [43] [85] [93] [1] [0] [17]..i create another six textboxes and at the same time allocate these numbers in ascending/descending numbers.I am not looking for any codes whatsoever, as i love the challenge of VB.Net.
1.The average of the four numbers. This answer will be placed into a text box reserved for that value. This text box cannot be changed by the user.
2.The maximum and minimum values. These will be denoted by changing the color of the largest number green and the smallest number red.
3.The range of the numbers. The range is defined as the difference between the largest and smallest numbers. The range will be placed into its own text box, labeled as such. This text box cannot be changed by the user."
Im using visual studio 2008 and it has to be written in VB
So how would I use .next (random numbers) to randomly select something from a list of numbers but it can't repeat the number?I could do:
dim num as integer dim r as new random num = r.next(1,5) if num = 1 then elseif num = 2 then etc.
That wouldn't work because it would repeat.If I donwload someone's game can I disect it in VS? :0 I tried going to open project, then I went to the folder and clicked open. It brought me inside of the folder so I tried to open the game but there is no form1 there. It says the games name then .exe in the explorer-like thing in the top right?Also, how would I have a value or something in a label and access it from a button.
Example:This is in a label.
Dim number as Integer number = 0
Then in the button do
Label.number = 0
How would I do something like that? I want to use that a lot as I did in a different language.
I have a program that allows a user to input numbers from an inputbox and it displays the Total numbers entered, the sum of the numbers entered, and the average of the numbers entered. What I can not seem to find it how to have it display the largest number entered. The code I have so far is,
I am making a program, where the user enters 6 numbers in 6 different text boxes, and it displays the larger of those 6 numbers. But I also want to make it where if the user enters a string value (like S for instance) in the text boxes, it gives an message and says "please enter the numbers again" and the user gets to enter the 6 numbers again. But when I do try to do that, it gives an error message saying conversion from "w/e the user entered" to Double is not valid. If the user just enters the numbers, it works fine. However, I am trying to make it if the user does enter non numeric value, it gives a message window and the user can reenter the numbers again.
Here is my code Example
CODE:
This is where I am trying to use IsNumeric to show a message if a user does not enter a string so the user can renter the numbers again, but when the user does enter a string value (say in textbox 1) it gives me an error message saying conversion from "S" to 'double' is not valid.
CODE:
Then right here this is where I have my series of ifs statements, this part works fine, it displays the largest numbers of the 6 textboxes every time. Error free.
CODE:
And do this with variable number 2, 3, 4, 5.
I know there are easier ways to do these with arrays and stuff. But I am not there yet. I am still learning about ifs and stuff.
I have just about completed a .NET project to write a program to randomly select numbers for a Bingo caller. Over the last month or so Ive learned a lot about .NET but heres something that I consider to be odd and maybe one of you guys can offer an opinion.
One of the features of calling Bingo in a small local club is that callers often use little sayings to accompany certain numbers, I expect youve all heard of (say) All the sixes, clickety click for 66 or 5 and 9 the Brighton line for 59 etc. My little program gives an option to incorporate these with a prompt for the caller that can be edited outside of the program. One of these conventional sayings is used when a number is reversed 12 followed by 21 or 45 followed by 54 for example, when the caller might call (say) 1 and 2, one dozen, number 12 And the other way round 2 and 1, twenty one.
So, I programmed in a bit of code to detect this and to over-ride whatever might otherwise have been the quote with And the other way round and set about testing it. Ive been through literally dozens of full 90 calls watching for the occurrence of a reversed number, spent a few hours doing it, and not once has it occurred which is to say the least, unusual.
So, Im wondering about the Rand Function, could it be that it isnt possible for a reversed number to be selected? Just so you know, I randomly pre-select the order of all 90 numbers, I fill each of the 90 elements of an array with a random number first checking that the number selected hasnt already been stored, if it has, I just get the next random number (and check that too of course), but I cant see how that could prevent reversed numbers being selected, especially in light of the fact that frequently it's not the 'next' number that's used.
am writing an system application for a company that must generate inquiry id and order id automatically. Whenever a customer makes a new inquiry or new order by clicking the add button, an automatic number should be displayed in the text box and when it's saved, it should be saved in the database access.
I am working on an assignment that will display the forst 10 fibonacci numbers in sequence. However when my results are displayed, the numbers are all stacked on top of each other like this: 011235813213455. I have tried to play with it but i can't seem to get my numbeers to space out or even maybe have a comma "," betweeen each number.[code]
