Pointers On Doing A Multi-website Search From Within App?
May 19, 2011
have an app where the user can select to search websites I have "Hard-Coded" into the app and select categories and sub-categories to search within those websites.What i need is to figure out how to take a user defined search query (Example: The Holy Bible King James Version), then search the relevant websites (behind the scenes) then output the results something like a google or bing search, then allowing the user to download directly their search query

What I am trying to do here is search a multi-line textbox that contains the source of a particular website.what I would like is something like this but i do not know how to right it like i need
Dim MyString, FirstWord, LastWord, MidWords As String MyString = "Mid Function Demo" ' would be the textbox FirstWord = Mid(MyString, 1, 3) ' Returns "Mid". LastWord = Mid(MyString, 14, 4) ' Returns "Demo". MidWords = Mid(MyString, 5) ' Returns "Function Demo".
this function works fine only when you define len.what I need is a function that will do something like this, "note obviously interpreted code"
Dim text, A,B,C as string text = textbox1 A = "<body>" B = "information between A and C being of variable len" C = "</body>" textbox2 = B
I do not want anything like,
remove "<>?|?()}{][" etc.

Currently i have this code:
If InStr(1, UCase(TextBox3.Text), TextBox2.Text) <> 0 Then
End If
which sees if text from textbox2 is in textbox3, but if there are multiple lines in textbox3 then it wont search.

I have a listbox populated with dates in the format of dd/mm/yyyy e.g. 12/03/1983, 06/07/1987 etc.. Could someone please post the code that I could use so that I could search the listbox to multi-select the dates that fall within a specific month (not year or day). So for example I might want to highlight all the dates that contain the month **/10/** (october). I'm really struggling with this.

Regarding multi column search, i want to clear you the situation where one column contains say FirstName and the another column contains LastName for the 'Contacts Combo box', then when user types either FirstName or LastName for the person, combo box should search for the appropriate value into both columns.
for my fifth question consider the same combo box with FirstName, LastName all typed together shows in one column only then, by default combo box searches only for strings that 'Start' with the string typed in the textbox portion, insted of which i need a feature which allows me to let set the behavior of combo box search system tobe able to search for the typed strings within any part of record.i.e. If user types 'Ja' in textbox portion, the the list should show following maches

Im using wikipedia and want related searches to pop in a listbox that the user can look at as well. If anyone has some insight of where to start that would be awesome. I tried getting the heading of the main searched topic by referencing the titles of the website but that ended quickly with many boundaries.

I am hoping to implement search in my asp.net website. I have been searching the web, but I am not sure which way to go. Here is what I am looking for:
ability to search the text in static pages on my site exclude pages or folders that I don't want to search code must be in vb.net or c# must be something I can quickly implement .net 2.0 or later preferred
The best example that I have found so far is [URL]
I like it. I am just hoping to find a more modern one. This one is written in .NET 1.0

Not sure if this is possible at all. I was hoping somebody could help point me in the right direction. Right now im not quite sure what to search for or what this would be called. Basicly I was wondering if it is possible to design a application in vb.net 2008 that could search a website for specific information.

I've just started developing web applications for the first time. Im developing an ASP.Net Website. Ive started transferring code over from my windows application and found a few errors. In my windows application I had a search function in a form where on click the text in a text box would search the first list box and print any matches in the second list box. [code] In my website an error pops up highlighting the line "words = lstSearch1.Items.Item(a)" and says that the value of the list item cannot be converted to string. How do I go about fixing this or is there a different way of implementing a search function in an Asp.Net website?

I need to perform search against multiple user properties in memory - I'm not using SQL.What's the most performant way to implement a 'user search' against multiple properties?

Id'like to pass some variables (string and integers) to a class, and when I call a method of that class, it has to change the original variable.I know it was not impossible in C#, but I'm using VB2010, I made a C# project into my solution, but methods using pointers are hidden into VB. How can I make that kind of change?
An example:
Sub ChangeValues()
Dim A As Integer = 1, Str As String = "Start String"
Dim X As MyClass(A, Str)
X.ChangeInt(2)

have a 2d array of structures that holds about 5 or 6 details on each cell. The array size will not be known at compile time so I am using ReDim to resize it. I also have a list (think I have it as an arraylist actually but shouldn't matter really) that I would like to hold a pointer to one of the 2d array elements (as well as some other info). The list is a much smaller subset of the 2d array. The reason I am doing this is that the list needs to be sorted based on some data in the 2d array that will be changing. I don't want to have to search through the list each time to update the values as these lists and arrays can potentially be very large.
Maybe there is a better way to handle this but even if there is I would like to know how to simulate pointers in VB.Net. I know there are IntPtr's and references that I could probably use but I have no idea how to do it with dynamic arrays of structures. I'm familair with pointers from C++ but this is the first time I have tried to use (or simulate since there seems to be no real support for them) in VB.Net.
Not sure how clear that was so here are some snippets of the data types involved and some initialization.
Code:

I'm looking for something similar to using vectors and pointers that I've used before in C++; unfortunately, it doesn't seem like there's an equivalent function in VB.net.What I have is a copy of the array behind a multi-line Rich Text Box, and I need to separate the words from each line (or element of the array) so I can analyze each one separately.In C++ I would do something like this, so I could continuously expand as needed:

i am new to commercial programing (and this site) I am currently studding Computer science at a university and i have hit my First roadblock.I am currently developing an application that displays a Table on one Form1 in a Read-Only format and a second Form2 which will only be displayed if after selecting a row on the Grid-View of Form1 you press an Edit button.We are doing that to avoid the User editing the DB in large. The Form2 is populated by a details view of the Table with no controls to change row on the table.What i am trying to accomplish is passing the information of which row was selected in Form1 to Form2 thus making it the current row and subsequently the only one been edited. Currently most things work but as soon as Form2 shows (Form2.show()) it will only display the first row of the database.I want to know if there is a way to "sync" the two indexes.

I'm looking to make a simple web traffic sniffer that will automatically reply toauthentication requests from a predefined source, but I'm not entirely sure how tostart/what I am looking at my self here.I guess it's easier to explain if you have a short backstory;I use WebDAV, but Windows does NOT have good support for this (lacking Basic auth support, and Digest support being flawed at best), so you are forced to manuallyauthenticate with a username and password every time you open a file, when you start your computer or a word document (for example) loads resource such as images (imagine writing yoru username and password for every image in a powerpoint!).

Since vb doesnt support pointers but c# does. I am using a wrapper dll that requires a pointer to some singles to be passed within the method. I get an error that the method has some parameter types that are not supported. How can i pass a pointer to this method if vb .net doesnt support pointers.

I am in the process of writing a tool to manage DHCP servers using the DHCP Server API. Its an unmanaged DLL so using it is a PITA at least for me it has been.Currently I am stuck trying to enumerate the IP ranges in a particular IP subnet. I am able to access an array of structures but I have only been able to access the first structure in the array of strucutres.Using this I can sucessfully access the first structure in the array.
Dim element_info_array As DHCP_SUBNET_ELEMENT_INFO_ARRAY
Dim element_data_ptr As LPDHCP_SUBNET_ELEMENT_DATA
...
element_data_ptr = DirectCast(element_info_array.Elements, LPDHCP_SUBNET_ELEMENT_DATA)
However when I use this to try and loop through them one at a time it does not work. The ptr returns 0 is null.
Dim element_info_array As DHCP_SUBNET_ELEMENT_INFO_ARRAY
Dim element_data_ptr As LPDHCP_SUBNET_ELEMENT_DATA
For i = 0 To size
[code]....
The sizeof for DHCP_SUBNET_ELEMENT_DATA could be off due incorrectly setting up the union structure for it. I was not sure how it define it so that only the first ElementType and one of the other components is avalible at any given time. It wont even read the first pointer though so that has not even come into play yet.

I'm trying to call C code in the form of DLL's from Visual Basic. When I do everything passed by value I have no issues. But what I really need is to return multiple pointers to arrays of sizes I don't know at compile time (so I'd have to dynamically allocate that memory). For instance
[Code]...
Here the array sizes are hardcoded but that's for the simple fact I didn't want to copy my whole algorithm over, in my actual code I wont know the array sizes at compile time. So my questions are these:How do I make the function declaration in Visual Basic 2008? How do I free up the memory in Visual Basic that these pointers point to?
