VS 2008 - AxWebBrowser And DataGridView - Retrieving A List Of Links From Current Web Page
May 8, 2010
I am currently redeveloping my web browser application using the axWebBrowser component. I have, up to now, managed to port most of the code from my previous application, which used the standard webbrowser component. How would I retrieve a list of links from the current web page displayed in the axWebBrowser and display them in the DataGridView? The following code from my previous application is giving me an error. [Code]

I know this is not the right place for this question but still I would like to create in Visual Studio a small site with related links based on what the current page is displaying, from what I understand it's about MVP/MVC

i want to be able to get all links from the current webpage, and then take the ones that have a certain part of the url. How can i do this. Basically I want to:
1) Get all the links
2) Delete the links that do not contain "/article/"
3) Put those links in a textbox.
I know how to do number 3, but how can I do number 1 and 2?

I am creating a program and have the following code to extract the URL's off of a webpage and put them in a richlistbox. This is only from one page. The problem is that I am only getting one URL into the listbox, instead of all of them off of the page.
Here is what I have so far:
Private Sub Timer3_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer3.Tick
Dim str1 As String = WebBrowser1.DocumentText

I can't figure out how to make my web browser open links in a new page or tab instead of IE. I've tired at least a dozen different sets of code. None of them can be manipulated to fit my browser. When my browser first starts, there's an empty tab control. I put a new webbrowser in it at runtime and set it's dock to fill. I create new instances of the browser for new tabs as well. I just can't find how to make it open links in new windows.

My application is intended to crawl a URL page and extract all possible links from the page.It works fine for a certain URL but with another it keeps causing problems. When the root page is accessed it correctly extracts the different directory links. but when it requests the directory links html page it pulls the main root URL again. someone mentioned about redirection but when debugging I see the url variable containing the directory link correctly.

I am using VB 2008 express and would like to know, If i can Replace a string inside of Javascript on page loaded into axWebBrowser so i can then execScript that function. The specific string i wish to replace is "_new" to "_self" this is so when i call the function it will load in the same page instead of popping into a new web browser. Also, is there a way I can just insert my own javascript function in the DOM as well?

I'm helping the IT department at my school do an audit of all our printers (there are hundreds). They are all networked, so I wrote a vb.net program that sends PJL (printer job language) commands over port 9100 to all the printers to retrieve the page count. @PJL INFO PAGECOUNT actually gets the page count for all the printers, but for color printers we also need to know the color / mono page counts (number of color pages printed, number of black and white pages printed).... the number being returned by the PAGECOUNT command right now seems to be the total pagecount on color printers, so if I can find a command that will give me either the mono or color page count, I'll have the other number. I also need the serial number of every machine (the spreadsheet I'm working off of is unreliable). @PJL INQUIRE SERIALNUMBER actually returns the serial number for about half of the HP printers, and some random non-HP ones, but I can't figure out a way to get the serial number for the other 50%. I sent emails to some of the people who wrote the articles about PJL I was following, and they advised I try using printer spooler functions (from my brief google search it would appear these are windows API's that facilitate communication with a printer).
Does anyone have any experience with working with the Printer Spooler functions or know a PJL command I might have overlooked that will help me get any of the info I'm looking for?here is my program right now. Ignore GetSerialNumber2 and GetSerialNumber3... they don't work (well actually GetSerialNumber2 works on 5 printers... but yea). GetSerialNumber() is the one that gets the serial number successfully for about half of the printers. (edit: I took out those functions in the version I posted, along with some other stuff that wasn't needed for this, to fit the post size limit)

I'm using this code to retrieve the list of files from a FTP server
Dim request As FtpWebRequest = WebRequest.Create("[URL]")
request.Credentials = New NetworkCredential(username, password)
request.Method = WebRequestMethods.Ftp.ListDirectoryDetails
Dim response As FtpWebResponse = request.GetResponse()
Dim responseStream As Stream = response.GetResponseStream()
Dim reader As StreamReader = New StreamReader(responseStream)
messagebox.show (reader.ReadLine)
It gives me alot of information that I dont need, I know that I can use:
request.Method = WebRequestMethods.Ftp.ListDirectory
Which only retrieves the file name but when I try to change it, it gives me an error. Error number 550. ListDirectory so I can only get the file name?

I'm just curious as to how some software programs that I see out there have the ability to extract links & text from thousands of web pages at an extremely high and fast rate. Has anyone here, ever created a link or text extracting program the has the ability to parse many webpages and return data into a textbox? I know how to extract links via the webbrowser control, but it doesn't seem to parse/extract data at a very high & fast rate like many email, link & text extracting programs that I see out there.

how could I get the text of a specific cell in a DataGridView control ? If it matters , in my case , all the cells contain strings or nothing . For example , in order to get the text from the cell on row 2 and column 3 , what code do I have to use ? I have tried the Value property but seems that's not it . I've found some examples on the web ,but they were all for C# ... I guess , though , it has to be easy .

Is it possible to (programmatically) retrieve the current line of code being executed? For example, I have program X that's only 200 lines long. Is it possible to tell a user "The current line of code is: ....."?Mods - Please do not mark my posts as answered. It is extremely rude. You have no idea if you've answered my question.
I WILL come back and mark the ones that are answers, as answers.

I am trying to create a specific aspx page where I display clickable links based on information in a sql database. For example one column could be the anchor tag another column could be the path to the link itself etc. In the past I would pull this information from sql and put it into a non-visible Label (say linkLabel1). Then in the page itself I would insert <%linkLabel1.text%> to insert the link path from the database to the appropriate area.
What I would like to do is set up a way that I could simply enter a new row into a SQL table with link information and a web page automatically displays the new link for me.
I guess I am mostly looking for insight, opinions, or directions of what approach to consider. I can elaborate if I was unclear (wouldn't be awfully surprising if I was not).

So, when someone makes a website, they decide if they want their link opened in a new tab,window, or in the same window. How do I make it by default that it opens in the same window, no matter what its set to on the website? I just don't like internet explorer taking over on those links.

My website is in the root directory, which is [URL]. I am using this:
Dim appPath As String = HttpContext.Current.Request.ApplicationPath
Dim directory As String = appPath & "/upload/" & Left(TableName, 2) & "/"
to get the path and it's working very well. But when I create a new sub-folder and copy some pages from the root directory into the sub-folder, my images are not displayed because the path has changed. This is the link from the page in the root directory:

I am trying to create a program in Visual Basic which will measure the performance of the CPU with every core, one at a time. In this program, I decided to place a couple of text boxes that display the processor speed and the actual processor speed. I need to get the actual processor speed to update and I have tried doing this already using a timer set to tick every second. However, when I load the program it runs really slowly and prevents me form doing anything within the program, including trying to close it down, and all it does is updates the text box every second. I have looked in task manager to find out how much CPU the program is using and it shows that my program is using 0 - 3% CPU.
Here is the code currently use
Private Sub Timer3_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer3.Tick
Dim mSearcher As New ManagementObjectSearcher("SELECT * FROM Win32_Processor")

I've been searching about how to list and remove or create all list of the ports forwarded on the current machine. So I can allow my app to create a port to allow the "chat". Wondering how this is possible. I saw many samples on net, tested most of them and none worked properly. Is there a possible way to edit ports with visual basic 08 or 11?

I tried using it and to get it to work I had to add some code to my project:
Public Enum HRESULT
S_OK = 0
S_FALSE = 1
E_NOTIMPL = &H80004001[code].....
I didn't like the fact that I had to use the MSHTML stuff (cause I think IE uses it also, and we all know that IE sucks :) ) and that I had to add code the make it work.Don't want to start a browser-war thread so neglect my last remark.Is there a different (/better) approach of parsing html-pages in VB.Net.Basically what I'm trying to do is get all the links (<a> tags) and embeds (<object> tag) on a page.

I want to capture the original value and the new value from a cell in the DataGridView control. When leaving the row, I tried:
dgDataEntry.EndEdit()
Dim row As DataRow
row = tbl2.Rows(e.RowIndex)
Dim m_orig, m_curr As Decimal
m_orig = row.Item("amount", DataRowVersion.Original)
m_curr = row.Item("amount", DataRowVersion.Current)
And the values were the same. How can I capture the different values?

I'm working on a project. I want to be able to right click on a webpage and click on my custom context menu item (let's say 'screen'). What this should do is get all the page source from the current web page from where I righ clicked and save it on the disk. Basically, "right click -> view source -> file -> saveAs ", this is what i want to do programmatically.
