I'm trying to analyze web pages for seo. I'm trying to create my own personal tool to extract all the keywords and tags from web pages (a little clearer).I already know how to extract or parse links and text from web pages. The issue is that I tried to implement title tags, body tags or keyword tags in general via using the following code:
Dim theElementCollection As HtmlElementCollection = WebBrowser1.Document.GetElementsByTagName("a")
For Each curElement As HtmlElement In theElementCollection
If curElement.GetAttribute("href").Contains("http://twitter.com/") Then
[code]....
Try to extract all the keywords from the title, body etc. for this page:[URL] and send it to separate textboxes (title keywords in textbox1, meta tags in textbox2 etc.).

View 1 RepliesI was just wondering how to extract or parse any particual tags (whichever I specify) from webpages. I know how to extract text and links from webpages, but I tried to use the same method from the following code for div tags, title tags etcetera and it doesn't seem to work:
[Code]...
Dim abc = WebBrowser1.Document.GetElementById("old_sl")
Dim theElementCollection As HtmlElementCollection = abc.GetElementsByTagName("option")
For Each curElement As HtmlElement In theElementCollection
Dim controlName As String = curElement.GetAttribute("value").ToString
If controlName = shortLang2("a") Then
curElement.SetAttribute("selected", "true") ' pass username from TextBox1
End If
Next
Above is the code I am using and I get null reference was unhandled error. What I want to do is to find first the element with id old_sl which is a <span> then I want to get all the elements into that span with tag <option>.
i have an application that loads a bunch of Mp3 files and then plays them. What I want to do is use a listview to display filename, album, artist and location. Now I can get the information into the listview no problem. BUT, I don't know a simple way to read in the ID3 tags from an Mp3 file.
View 3 RepliesWith my code as I have a trouble with the returned strings that I have extracted from my php source to add the strings in my listview.
I'm reading the tags of mystrings1 and mystrings2 for each paragraph from the php source. I got the returned strings which it looks like this:
PHP
<p id='mystrings1'>my strings</p> | <a href="http://xfvasfasfasfasf">Link</a> </td> | <a href="delete.php?id=0">Delete</a> </td> | <span id="mystrings2">Enabled</td>
I want the returned strings to be like this when I reads the tags of mystrings1 and mystrings2 while ignore the other tags.
PHP
<p id='mystrings1'>my strings</p> | <span id="mystrings2">Enabled</td>
Here's the
Public Sub timer1_Tick(ByVal sender As Object, ByVal e As System.EventArgs)
timer1.Enabled = False
timer1.Stop()
[CODE]...
Do you know how I can ignore the other tags when I get the returned strings of mystrings1 and mystrings2?
I've got a lot of text that I'm pulling into a string, potentially.
In the text - I'm embedding "Tags" or "Labels" for certain sections. These tags will be used so that I can pull text out of this one string and then break it down into parts. How would I go about doing something like this? Each "tag" will begin with the tag name in square parenthesis and end with /name in parenthesis.[code]...
I have a SQL Server table with a list of files (path + filename), and a folder with multiple layers and files in each layer. I'm looking for a way to reconcile the two without having to process the list twice. Currently, I'm doing this:
For Each f as FileInfo In FileListFromDatabase
If f.Exists is False, mark it as deleted in the database
Next
[Code]....
Is there a better way to do this? I'd like to avoid converting all the matching files (of which most will be) to FileInfo objects twice. Since I'm a T-SQL developer first, I'm picturing something like an OUTER JOIN of the two lists where they don't match. Something LINQ-ish?
I am planning to create a system for my case study wherein i can Add tags from images and search for it by "tags" such as photobucket. For example i open an image to my system, and it's file name was "WhiteHouse.jpg" and i added or tagged it as "Building". Once i search on my computer, and type the word/keyword "Building", the image "WhiteHouse.jpg" will be displayed on search results as i tagged it on my system.Is that possible guys? or i can only search by tags using my system/application? and not in the search command in my computer?If it is possible please tell me what to do. or if you have sample vb.net2008(windows Application) files it will be helpful. Or if you have sites related into it. pls send me those links, especially downloadable vb.net files w/ codes for further studying.
View 2 Replieshow I can search a folder of csv files to find out if one of the csv files has a particular name in ?I'm currently searching a folder to bring back all csv files using the code below and this is working fine.
[code]...
But now I want to take it a step further and actually search within the files themselves.
I have come up against another brick wall I have a large number of .csv files which are located within subdirectories of lets say the "c:emp" directory. What I need to do is find all of these csv files, open them individually, perform an operation on each and then close each one.
What I am struggling with is the part where I find all of these csv files. What I would ideally like to do is search through each of the subdirectories, return a filename (including complete path) as a string which I can then use in my code to open the files individually and perform the operations.

I've created a button and textbox which allows me to do an openfiledialog and select multiple files. The problem is, after selecting multiple files, when I run the program it doesn't run through all files selected, just the first file. I know I'm missing an integral part of code here, but not sure what it is.
For testing purposes I've created similar code and output to a textbox shown below. I would expect that each file selected by multiselect would appear in the textbox provided.

I don't know enough about VB.Net (2008, Express Edition) yet, so I wanted to ask if there were a better way to find files with different names but the same contents, ie. duplicates.In the following code, I use GetFiles() to retrieve all the files in a given directory, and for each file, use MD5 to hash its contents, check if this value already lives in a dictionary: If yes, it's a duplicate and I'll delete it; If not, I add this filename/hashvalue into the dictionary for later:[code]Is this a good way to solve the issue of finding duplicates, or is there a better way I should know about?
View 2 RepliesI'm trying to find a good strategy to access data files, image files, etc., that I want to distribute in my VB.NET deployment. The challenge I'm having is to find a place to put the files, and a means for the program to find them, regardless of whether the program is running in the Visual Studio environment as a debug build or release build, or running as an installed application.I've considered using AppDomain.CurrentDomain.BaseDirectory to find the location of the EXE file, then using relative paths to that folder. However, that approach depends on the directory hierarchy imposed by the Visual Studio tools when it separates the binaries of debug and release builds. Both builds would have to navigate upward to reach a common root folder, and the path traversal algorithm must work for the deployed EXE file too.

I'm making a Cleaner for my PC that could delete all files with a specific name.So I have all the names in a .txt file, like:
A
B
C

Now I need somekind of function that would search in a directory ( The user gives the dir. in a textbox ), and its important that it would also search in all sub folders and see if there is a match to any of the names in the .txt file. And it shall not care about in what format the file is. It can be in .exe , .txt or any format.

View 13 RepliesI (through a ton of help from everyone here at stack-o) have created a small WCF which is hosted as a Windows service using TCP..Last question for this little bugger; it's time for deployment. In my solution, there are 3 projects. One is the Windows service, another is the imported WCF, and finally a setup project I added for install.I can install/uninstall the service on my machine by going in the solution directory and finding "Setup.exe" or "Setup.msi". Executing either from explorer will install the service on my development box.Now there are a few directories associated with this solution. I'm betting that simply copying setup.exe or setup.msi to my target server and trying to run it will bomb out. How can I find out exactly which files/folder I will need to copy over for deployment?Or should I just copy the entire solution directory? That will be a little difficult for my coworkers as the setup routines are nested in directories 5 deep.

View 6 RepliesUpon my program startup, I need to see if an Excel 2003 file with a certain name is open and then control it (set a reference to it). Unfortunately, the path of the Excel file is not set; else I could just detect if that file was open. So I guess I need to somehow loop through all open instances of Excel; then once I set an Excel app reference to each instance I could loop through the workbook names... But how would one go about looping through open instances of Excel in VB.net 2008?

I got the computer from my friend named John and the user I have all of my stuff on is john. If I change the username is it possible that things coulds get messed up?

View 5 Repliesso I had an idea today while modding a game I play. I decided to make a mod-manager.In order to start the game with mods, you have to go to the website, log in, click playnow and view the source of the html file. From there you get the sessionID variable and add it to a shortcut on your desktop. I wanted to be able to automate this process by doing the following:
on button1.click: somehow parse the source of the html file to locate the line that looks like chis:
var sessionId = 'random26charSessionID'; and take what is inside of the ' ' and add it to textbox1.text
Any ideas? Not sure if it will be in the same line every time with add banners and stuff...so I wanted to parse the doccument.
