I have a website with product pages that are created dynamically depending on the itemws in my database. The site works fine with no errors. I now would like to add Meta Tags to the header.
When the pages are created I would like to dynamically/programmically set the meta tags for that page - Keywords, etc.
How can I add them using VB.Net in Visual Studio 2008. I am using a masterpage for the overall layout if that affects anything.
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.).
I have this code.
Code:
Public Class Form1
Dim NPB As Button
Dim x As Integer
[code]....
As you can see, when I open a program from my menu, a new button will be created with text similar to this, "C:Program ". The button it self will not do anything. How can I create the method at the same time the button it is for is created? Also how can I change the text do that it gives me, for example, CCleaner.exe instead of the whole target path?

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:

When in VS 2008 if a developer hits the ''' it generates the XML comment tags for you, but this only works when the project setting for "Generate XML documentation file" is checked. Is there a way to tell VS to generate the XML Comment tags, regardless of the project setting? I think it is possible that someone may want comments but not create a XML documentation file. In this case I am exceeding the current Team Settings, yet other developers don't want me to change this project setting. This forces me to flip this back before checking in the project. I have the same problem with other Project settings like "code Analysis". This is only a problem for VB.NET projects.
View 4 RepliesI have a multithreaded app that is throwing the following error.Collection was modified; enumeration operation might not execute.[code]I'm pretty sure the collection is being modified by another thread. I attempted to fix the problem with the SyncLock's but clearly I'm missing something here.I thought I could lock the object by properly using SyncLocks, am I just not locking the right object(s)? Or am I completely missing something here.Besides using SyncLocks what other options do I have to prevent this error. I was thinking perhaps a global variable to keep track critical code sections so that no 2 threads enter.I'm also a little confused about what collection is being modified my first guess was CLResultsDataTable. ResultsDataTable, but I'm not sure.This is an older project I just recently picked back up so I'm still stepping through a lot of code to try to figure out how/why this is happening

View 4 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

View 1 RepliesI am working on a simple windows app that will take our TripleDESCryptoServiceProvider Key and IV from a file and use it to Encrypt and Decrypt strings, etc...This works great and has for years in a utility program, but I want an easy app that can read the Key and IV...following format in the txt file:
[KEY] {123,123,123,123,132,132,123,...}
[IV] {23,23,23,23,23,...}
And then create the Encryption Pair...Currently I have the following
clientDESCryptoServiceProvider = New _
TripleDESCryptoServiceProvider
clientDESCryptoServiceProvider.Key = New Byte() {111, 222, 333,...}
clientDESCryptoServiceProvider.IV = New Byte() {1,2,3,...}
Is there any way to pull the {111,222,333,...} and {1,2,3,...} from a text file and create the Byte() that is required?I can read the info from the text file, but cannot seem to create the right format for generating the Byte()?

View 2 RepliesI would like to dynamically create an object (in my case a thread) and then be able reference that object. Simplistically put, I would like to read from a text file and then process each item using a thread (so that I don't have to wait for each item before starting the next). The problem is that I cannot think of a way to create a new thread dynamically ie. thread name so that I can then wait for all created threads before doing something else.

View 5 RepliesWe use a common web.config file to store all of our database connection strings.
I would like to have a way to read in all of them, somehow create a property or type so that they become dynamically available.
So when I want to create a new sql connection my my class can show the connections strings available.
Dim myconn as new MySqlOps.Connection(MySqlOps.ConnectionString)
so when the user types MySqlOps.ConnectionString. it will give a list of the connection strings read in from the config file.
Not sure how to approach making the connectionstrings available like above.

This may be simple, but im having a tough go at it. I'm trying to make a "review" section in a step through form, where the user can see everything that has been entered and if they choose go back and "edit" that information again. One section only has to show the information that has been added by the user, basically if they don't select a certain checkbox there is no reason to display the info for that box.I want to to dynamically create labels in a Panel (Panel7) on a TabPage (TabPage3), only for the checkbox information that was selected. This is what I have right now, and I am unable to see anything on the page, I have also tried without the panel and straight onto the tabpage itself to no avail.

Obviously, this isn't how I started out. But I've been trying everything I can to get it to actually display. If I have a PictureBox with exactly the same properties, it displays when I tell it to. This way, it doesn't. I even created an entire class and used that - nothing. I'm guessing it may be the fact that I used a Dim statement, but I'm still a teensy bit novice-y to certain aspects of VB (in particular, Image handling).
