one of the BIG hurdles in my simple project, making a search engine. I don't know how at all. The search engine need only to search in one Directory with its sub directories and txt files for criteria, and display the results, with option open from the results. any basic code or example maybe?

i have been trying to search a specified directory and all sub directories for all files that have the specified file extension. However the inbuilt command is useless as it errors up and dies if you dont have access to a directory.
Private Function dirSearch(ByVal path As String, Optional ByVal searchpattern As String = ".exe") As String()
Dim di As New DirectoryInfo(path)
Dim fi As FileInfo
[code]......
However i get an "System.NullReferenceException: Object reference not set to an instance of an object." when i try to access the data stored inside the filelist string array.
i want to ask that how i can open a search page in my vb.net webbrowser with a separate textbox in a tool bar separate from the url text box

I have a series of text files in multipule diffrent sub directories. I found the following functions on the Internet:

The functions will make a direcotry tree in my debug window, that looks something like this:
CODE:
What I want it to do is to have it return an array of relitive file paths, from the starting direcotry I give the function. Then I will use a loop to cycle though each file in the array to make certain changes.
Something like this:

Any ideas on how to acomplish this?

View 1 RepliesI have a search engine that is supposed to search through descriptions of products and then will display something with a list of products that have whichever word(s) or phrase the user was looking for. I haven't made any kind of list for the products that use the description though.

So everytime i click on 'A', it will go into the database and search for all the stuff that contain 'A' and display on the flash textbox. If i type 'An', i will appear all the stuff in a Flash textbox. Just like yahoo, when you type 'An' there will have a downdrop appearing all the words that starts, end or inbetween have 'An'.
View 6 RepliesI have a system on my webbrowser that allows the user to choose their Search Engine out of a selection I organized. the down point is that I have it set so when they click save it will just hide, because if it closes the settings will be reset and not saved. However I want them to save. Here are my codes to the search button:
Private Sub Search_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Search.Click
If SearchEngines.RadioButton1.Checked Then
CType(TabControl1.SelectedTab.Controls.Item(0), WebBrowser).Navigate("http:www.google.com/search?hl=en&q=" & SearchBar.Text & "&btnG=Google+Search&meta=")
[code]....
This is the code of save:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Me.Hide()
End Sub
I would like it so it saves when the whole program is closed, so when they start up it's automatically set so they can search on their favourite search engine.
provide me source code of search engine?

Is it possible to build a search engine to use on a DVD that contains Word documents, text documents, etc.? Say I wanted to find all documents with the name "James" in them. In the search box I would type "James", and it would return the results of everywhere James is found. Or suppose I wanted to find all Land Deeds where James is found, is that possible? All search engine examples that I have seen on VB Help has to do with databases, and I guess to an extent, my DVD would be the database.

I'm trying to create my own type of spider/search engine thing for fun. I start with a URL, then grab the HTML ...from that I have a REGEX that is supposed to pull out all the links. I figured I would randomly pick one of those and keep going as I save the HTML to my database.[URL]...You can see that I get some real URLS and sometimes I get back some that are not. NOW I return these to a RichTextBox and on the REAL URLs, these get formatted in blue and make a HAND icon when you float over them. This makes me believe that something SOMEWHERE knows that these are good url's. That would be a good thing to tap into so that I could get rid of everything in that box that is not a real URL.
