Detecting Internet Explorer Events and Reading Properties...

Using Visual C++, I need help simply detecting a few IE events (NewWindow2, BeforeNavigate2, OnVisible), retrieving a few property values (LocationURL, etc) and calling a couple of methods (Navigate2, Refresh2, Stop, Quit).

I am very familiar with VB and OnEvents, however have no idea how to capture this info in VC++.

I am not looking to include a browser within my app, but retrieve the above info on any instance of IE running on the machine.

I am willing to allocate many more points for an actual VC++ project created that will simply do the above (maybe a messagebox on the events) and emailed to the email account I created just for this: Adrenaline__X@hotmail.com
(Note that there are two underscores in the email addy)

Thanks in advance for the assistance.

It is spelled out here, including plenty of sample code!

DanRollins,

Your first link is one that I have already tried, and it does allow me to "Connect to a Running Instance of Internet Explorer (Q176792)" just as it states. And I can also detect WindowRegistered and WindowRevoked events, but not the events that I wanted (NewWindow2, BeforeNavigate2, etc.)

The second link appear entirely viable (except I was hoping to not have to create the app as a dll and register it) but my VC++ are lacking and I can't get a functional sample from the code given.

Again, if someone were willing to create a working project and email it to the addy above I would be willing to increase the points substantially.

Sorry, I meant a non-BHO/dll working project...not just emailing the code that is given in the above link =)

For a non-DLL solution, I'll chip in a few points too.

Ok, I see that I bit off more than I can chew here...

Dan,
Your second link (the BHO solution) will probably be my best bet, but I can't even compile the code that is provided in the link...

I am running VC++ 6 and the project is converted from the older version as I open it and I receive the following errors when attempting to compile:

Compiling...
EventsDlg.cpp
E:\SSleuth CPP\BHO\EventsDlg.cpp(44) : error C2664: 'unsigned int __thiscall ATL::CWindow::GetDlgItemTextW(int,unsigned short *,int) const' : cannot convert parameter 2 from 'char [260]' to 'unsigned short *'
        Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast
E:\SSleuth CPP\BHO\EventsDlg.cpp(46) : error C2664: 'Navigate' : cannot convert parameter 1 from 'char [260]' to 'unsigned short *'
        Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast
E:\SSleuth CPP\BHO\EventsDlg.cpp(63) : error C2664: 'GetTextExtentPoint32W' : cannot convert parameter 2 from 'const char *' to 'const unsigned short *'
        Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast
IEHelper.cpp
IEHlprObj.cpp

        Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast
Generating Code...
Error executing cl.exe.

IEHelper.dll - 4 error(s), 0 warning(s)

Help me iron out these to produce a working copy of this example and the points (along with more) are yours...

Those errors look to be related to the use of UNICODE.  For instance, GetDlgItemTextW() is aclling the 'Wide' version of the fn.  And strcmp is looking for 'unsigned short' which is an alias for UNICODE character data type.

Check the project settings aand turn off the use of UNICODE then clean and rebuild.
