Yup. Imagine having a table in a database, where you link the "HowTo" video's to individual keywords. Retrieve the HTML when a page loads and check if it contains any keywords that are in your table. If so, display the videos that go with those keywords.

I developed a Vertical IE Explorerbar using this artical
http://www.codeguru.com/cpp/i-n/ieprogram/article.php/c4395
Now my next assignment is, whenever someone searches for anything in google or yahoo. My application should trap that keyword and display the search result using my websites search engine that explorer bar. How can I accompalish this?
Thanks in Advance

How would they do this, do you mean using IE or your application?

Sorry for the confusion, IE Addin was developed using ATL COM. So by application I mean the Addin. So I want the Addin to capture the keyword that was typed in the searchbar of google, and then my site itself has a search engine.
So it should query that keyword in my site's search and display the result page in the left explorerbar window

I think you may need to talk to the person who developed the addin, it's not clear from your question how it interfaces with the address bar.

Not the address bar, I need to extract the keyword entered in google or yahoo search

Sorry, I've no idea if that is possible, the contents of Google/Yahoo pages are controlled by their respective servers and driven by script within the pages. You might like to try posting this query to the Web Development or ASP.NET forums to see if anyone there has any ideas.

I think I am unable to explain properly. Lets make it simple. Lets say I have that IE Toolbar installed and some user typed 'Silver' in google or yahoo search. Now my IE Toolbar should extract this keyword 'Silver' when the user pressed search button. So I don't think it should be that hard. So can someone tell me how can this be accompalished.

So you need to find some method of intercepting the button press, if that is possible.

Yes. Not really intrcepting that button. Whenever someone press the search button. iHtmldocument2 should have a way to extract the keyboard that was send using http send / post methods. I am not sure though thats why I posted this question

The problem is that pressing these buttons does not trigger a search action within IE, but rather a post back or script action in the web page. This will then send information back to the web site where the actual search takes place. I have no idea how you would capture this action but, as I suggested previously, it has nothing to do with ATL and is more likely to get an answer in the ASP.NET or Web Development forums.

In this case, what will ASP.NET or any other web development do? Its not that I am using or developing my own customized page. I am taking it from google or yahoo

I think perhaps you need to understand how web pages work. What you are trying to do is capture information from a web page when a certain action happens on that page. I have no idea how you could do this, but people with experience of internet tecchnology may be able to suggest something useful.

That might be considered "phishing".
The easy way? Change the HOSTS file to point to your site

Why would you want to do this? Hijacking the users intentions like this seems to be the sort of thing which is best described as malware.

please help, need to access CListBox on ATL Form
CListBox* lb;
HWND w=frm->GetDlgItem(IDC_LIST1);
lb=(CListBox*)w;
lb->AddString(s);
I understand that CWnd and CWindow are quite different things, but still have no better idea (

You cannot cast a HWND to a CListBox* , there is no connection between the two; an HWND is a Win32 handle while a CListBox* is a pointer to an object of type CListBox which is a C++ class. You will need to use some different code to find the pointer to your object; if it's a property of your form then it should be fairly easy to find.

yes it`s property of my form.
I created ATL simple control, then add composite control to it, then drag list-box item from toolbox on it.
I need to access that listbox from static function where i have only pointer on this form
unsigned int __stdcall MyFunction(void* _pEl){
CMyDialog* frm=(CMyDialog*)_pEl;
// ???
myLstBox->AddString(L"whatever");
}
|
|
|
|

Solved:
HWND list =frm->GetDlgItem(IDC_LIST1); //Retrieves the list control from the window
TCHAR* w=L"whatever\0";
SendMessage(list, LB_ADDSTRING, 0, (LPARAM)w); //Should retrieve the data from the specified index
)))

I am moving our project from VS 2005 to VS 2010 and am running up against some linker errors. std::string being multiply defined is one issue, but I will take some more time to look into that one. The one I am really confused about is the std::string constructor.
We have been using
std::string abc(aCharArray, 20);
std::string anotherExample(aStdString.c_str(), 20);
without any problems. Now VS 2010 is giving me an unresolved external during linking. It is thinking I want the constructor std::string(const char*, unsigned int) which IS what I want. It used to be defined, and it does still seem to be defined. For some reason, updating to VS 2010, it is no longer linking, though. Is the implementation for this constructor perhaps missing? Anyone run into this or can anyone confirm the same issue? Thanks.
Resolving these is pretty easy, but I am left confused as to why it gets unresolved external.

I ran into something I don't understand. The following line is producing another unresolved link error. 'buf' is a std::string.
std::getline(stream, buf,'\n');
We have the same line of code in other projects that compile just fine. Below is the link error. To resolve the problem, I changed buf to a char[1024] and am calling stream.getline(buf, sizeof(buf), '\n'). But why am I getting this link error in the first place? The projects which compile fine are REQUIRED projects for the project giving me this problem. I don't know if the chain of links has something to do with this, but I thought I'd at least mention it.

Looks like you're not linking to the library that contains the definition. First thing I'd do is create a new console project and see if it works there. Something like this should do:
#include "stdafx.h"
#include <tchar.h>
#include <string>
#include <sstream>
#include <iostream>
int _tmain(int argc, _TCHAR* argv[])
{
using namespace std;
string source = "First line\nSecond line\n";
istringstream iss(source);
string line;
while (getline(iss, line))
{
cout << line << endl;
}
cout << endl;
return 0;
}

I just compiled this with my copy of VS2010 and it compiles and links fine. There must be something else in your configuration that is causing the problem.

Thanks everyone for the helpful input. It does seem like something strange with the project. I wrote a test console application and got no linker errors. And the same calls link in other projects within the Solution just fine. I compared projects and am unable to find a difference between a project that works and a project that does not work.
I am now trying to clean up code. The pre-compiled headers have includes for a ton of STL includes. I removed the one for string and am converting the headers and CPP files appropriately to see what happens.
Anyway, it does seem to be something odd with this project. Everything worked fine in VS 2005. We never upgraded to 2008 and now I'm converting to 2010.
EDIT: As a result of this exercise, I did run across several headers which were also including string, so I was able to clean those up.

Compare the project files using a diff tool.
