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 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:
The Cursor Class Does Not Support Color cursors. Anyone know how to get around this so I can use my custom embedded color cursor? If you want something you've never had, you need to do something you've never done.
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.
I save the bus Information in the two-dimensional array.As follows:
array 0 1 2 3 .............................. 0 106 A B C .............................. 1 102 D A E ..............................
[code]....
Array(x,0) are bus lines,behind its are place.Now I want go to the E form the A(pass 106),but A can't direct to E.But A can pass 102 to E.So line is [106-102].How can I achieve the bus transfer?
Most of our development is done in vb.net (not my choice) and one frequently used code pattern uses an 'On Error GoTo' followed by a 'Resume Next' so that all database fields can be read with a DirectCast() and any DBNull values are just ignored.
The current code would be On Error GoTo error_code oObject.Name = DirectCast(oReader.Item("Name"), String)
I know I'm being quite pedantic here. But, what is the right way to get a true 50/50-chance with a generated random number? Say, to simulate the flip of a coin. [code] I know this difference is close to nothing, but I'm doing some calculations on bell curves, in such a way that it requires true 50/50-chance.
I want a modal screen on startup of the computer, so that user forces to make some action on that screen. Also I want to disabled close button of the screen, It should cover entire Desktop.How to achieve using winform/webform? is parent/child form is the only solution fro this/?
I was wondering how to achieve a list with all possible combinations of letters. Now there are some nice examples on the Internet, however, I'd like to have the following:
Let's assume you have 3 letters (A, B, C), and have a limit length of 3, then it should display this list:
A B C AA
[Code].....
Now, this would be fine with recursive calls I think, but I find it really difficult to think how to code that and how the computer will execute the code. It would be easier if all possibilities had a length of 3, but here that isn't the case.
I have a class that uses a BackGroundWorker to download a single file using HttpWebRequest and HttpWebResponse
Downloading single file works.
But if I make two objects of that class and start downloading 2 different files simultaneously, there is nothing produced. Execution exits after getResponse() without any error or exception.
Is there any way to achieve simultaneous file download?
I am trying to achieve the look of the attached image using string.Format and PadLeft/PadRight but I have no success with it, anyone who could offer some help?
EDIT:The font I used is not mono-spaced and I am not inclined to use a mono-spaced font for this.
I have seen this done in C#, such as here although, I cannot seem to figure out how to do this in VB.NET. For some background, I have created a custom ComboBox control as a .dll, and I need to implement it in another .dll(ArcMap Component)
We have developed a vb.net application using multi-threaded listener concept and a dedicated thread for each folder to monitor. With that we simultaneously keep track of the incoming files in each folder.Currently, we are facing an issue whenever we receive multiple files of bulk volume, parallel processing of the files getting delayed with thread concept or failing sometimes.We need to implement the same logic with some other concept avoiding multi-hreading. Or is it possible to achieve performance tuning with the same thread concept?
Update to my Question the best way to achieve acceptable security is to use ASP.NET Web Site Administration Tool the following is only a demo to use session but it is NOT RECOMMENDED for professional use. follow the advice of PhillFox to achieve better results
When developing ASP.NET websites (using VB.NET web forms) - a lot of my time is spend writing CSS files and they always seem to get messy (code duplication) and very long.
All I want to achieve is to be able to manipulate the CSS using VB.NET code in the following ways:
Use an integer variable to store my "golden" number 7 and use that for width, padding, margin etc where needed Use string variables to store my "golden" hex color codes e.g. "#44C5F2" and use them for color, background-color, border-color etc. where needed Use an integer variable to set the height of an element and have four child elements each with height: mynum / 4
I just want to use basic VB.net number and string manipulation in order to create a CSS file on the fly.
I understand that the end product - the CSS file shouldn't change much - it should at most change on a daily basis otherwise caching couldn't be used.[code]...
I am having a perl script through which i achieve is split or output from text file for each single ID , the output text file will contain data of that ID and the anme of the file will be ID.txt so if i am having one main file containing 100 or 200 ID's and for each ID's may be 10000 or more lines i would like to have 100 or 200 files containing data for each single ID which i am able to achieve from perl but is it possible from vb.net
open(TH,"myfile.txt")|| die print "not open1"; open(THG,">error.txt")|| die print "not open2"; open(INFO,">myfileAll.txt")|| die print "not open3"; $gt='0'; $flag=0;
This is what I would like to achieve:To create a custom messagebox, with varying number of buttons with custom .Text descriptions, and other features. I intended to have a property array that would be redim-ed and have values (.Text values) set by the calling class:
I came across this great article on creating a custom datagridview column which creates a graph-like effect in the cells of a custom datagridview column:[URL]..Does anyone know how you would edit this to format the number in the cell as a percentage? And does anyone know how you would set this up to take 0 values which do not create any graph effects at all.I have been trying to do this but keep getting errors.
I was trying to block the closing of a custom combo box popup window in my custom DataGrid. The popup window comes by pressing F4 or ALT+DOWN keys in my datagrid which is getting closed if I press the down arrow for the first time, after showing the first value in the combo box as selected. Next time onwards, if I press the F4 key and down arrow, I can move to any item in the popup window and select the item using keyboard and in that case, the popup window is not getting closed till I press the ENTER key or selection using the Mouse. Is there any specific reason for this behaviour or something is missing in my code part? [code]...
