VS 2010 Unable To Get Information From Field On Webpage
Jul 1, 2011
What I want to do is to get information which has been stored on a webpage in a hidden field.
I have been able to put information on to a web page using the following
WebBrowser1.Document.GetElementById("email").InnerText = email
WebBrowser1.Document.GetElementById("college").InnerText = coll
WebBrowser1.Document.GetElementById("status").InnerText = status
[Code]....
I have tried various lines of code but non of them seem appropriate for what I want to do. The current line I have got is:
'hidfld is the hidden field on the webpage which I want the info from
findword = WebBrowser1.Document.GetElementById("hidfld").OuterText

I need to navigate to a webpage and copy a string of information from it within the shortest possible timeframe. The site has the following written on it:This is the string that you need to apply to your algorithm.
Generated String: 61*76*83*47*69*88*
I want to copy the string from the webbrowser control and place it into a string called "GenString"

I'm trying to pull information from an XML webpage but for some reason it just isn't working. The XML webpage looks a little like
<?xml version="1.0" encoding="UTF-8"?>
<item>
<reqdat>Date and time</reqdate>
<result>Completed</result>
</item>
I want to get the node, but everything I've tried hasn't worked :( I think what I need to do might have something to do with SelectSingleNode but I'm not sure.

I am having a bit of trouble figuring out how to collect a piece of information from a web page. Here is the web page I want to retrieve the information from:
RuneScape - The Number 1 Free Multiplayer Game
I would like to retrieve the first "Price" of the item and collect the price every time I execute the code. I understand how to retrieve the source code of the webpage and split strings but how would I retrieve that price?

I've currently got a service that produces xml files every 10 seconds containing server information. I'm looking for a way to display this on a web page. I have been looking on the web for the best way to do this and it seems that using AJAX would be good as it allows the loading of dynamic content to be done in the background. However how can I use AJAX? Should I add a ASP.NET website to my visual studio project? OR should I look to use javascript & AJAX in something like dreamweaver? I'm very new to programming so i only really have a bit of experience in vb.net.

I am trying to take specific information from a web page and then process that information so that it can be sent to a label or text box.Previously, I had wanted to do this by using Regular Expressions. I've looked around and it seems that using regular expressions to parse information isn't always the best way because website aren't always coded to standards.Regardless, learning regex isn't working out too well for me. So, I was wondering if there was another way to do this?I was thinking that I might be able to use the web browser control. It would be ideal to be able to see the page in the form, select the information, and then be able to display it.

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,

So I have a form that uses a datagrid with checkbox selections for multiple (read as many!) items.When I click a button labeled "Save to file", all the information on the form, to include the values of the selected datagrid items are then saved to a database. It works great most of the time.However, I have found that if I select more than 3 items in the datagrid, I get an error pointing to the data set and data adapter stating "OleDbException was unhandled - The field is too small to accept the amount of data you attempted to add.Try inserting or pasting less data".The code it points to is:
da.update(ds, "TrainingRecords")
In the dataset, I have tried to change the max length of the associated field.It was set at 255, and as long as I stay under that, I seem to be fine. But if I go over it, I get the error. I can change the design I guess to make it less wordy and therefore store less data, but is there an easier way?

I am using bindingsource.find to quirie information, its working so nice but I have a problem when the bindingsource cannot find the information I want it to show me the information that is inside the field, even knowing that the information that am looking for is not there:
I have something like this:
dim findinformatio as string
inputbox=(type the name)
dim findme as intenger=me.bindingsource.find("LastName", FindName)
me.bindingsource.position=findme
if bindingsource.position=findme then
msgbox(Findname)
else
msgbox(me.bindingsource.find("LastName", findName)
I am doing it because if the information that am looking for is not in the record field. I want the bindingsource show me the information that is inside the recordset field(LastName). I used to do it with odbc and works fine but with bindingsource I cannot, Why? And I have a compact database, sdf. I loaded the tables on my project.

If I have this to read from an access database, how could I translate it to read from an oracle database with the same table/field information? I know nothing about oracle but I assume I cannot use the oledbdataadapter that I am used to when connecting with an oracle DB.

I am faced with the prospect of having to completely rewrite the application.I have suddenly started to get this error message all the time - it seemed to start after I added a table to the schema, but deleting the table makes no difference. I can't see anything wrong with the connection string, but as it seems to be entirely undocumented, that doesn't mean much.
The connection string contains DataSource=.SQLEXPRESS;AttachDbFilename=|DataDirectory| est.mdf;Integrated Security=True;User Instance=Trueand certainly the string works when I use "test connection" from the application setting edit box. I am assuming that for some reason it is not evaluating the Data Directory , but can't see any reason why it shouldn't. Any ideas gratefully received! What might be a clue though is that I can't get rid of the table I added. I have deleted it from the database, deleted it from designer and saved the file, but it just keeps reapearing! Even when it is not showing, there is still a
table adapter in the .xsd file. I am reluctant to start editing this manually because of the danger of screwing something else up - I did try but it caused an error somewhere else (VS helpfully didn't say where)

I have been searching a lot online but couldn't find a solution for my problem. I want it to refresh every certain interval of time without this message to display. Now Ican't minimize my program because I'm putting an automatic Sendkeys.send("{Enter}") after the refresh to get rid of that message by clicking on "Retry".And If I minimize it the Enter will be executed on the active Window, which might be any other Window.
I hope that you understand what I mean, If not, I will clarify more.

Basically, I have a Web Browser object on a Visual Basic form. However, about 5 seconds after it finishes loading ANY webpage, the entire program stops responding. I figured the issue was related to internet explorer, so I updated to Internet Explorer 9 Beta and the issue is fixed (this is a very strange fix)!!! However, Internet Explorer 9 is not available for Windows XP.
