OK - I see what you're doing.
I'm not familiar with BHOs - but would guess they don't get much vote - on the basis that since the hosting environment is customizable through IInternetSecurityManager, it implies you're pretty blocked-out from anywhere else - as you've found out by being on the wrong side of the ProcessURLAction method.
Maybe setting the zone as a whole when the toolbar is active will give you what you want - the zone is customizable and can be published to the Registry I believe. Using IInternetSecurityManager::SetZoneMapping ?
Even more hacky, would be to trap DWebBrowserEvents2::BeforeNavigate2 and cancel the navigation (...I'm going to wash my mouth out immediately for saying that...).

Hi,
My question is really two-fold, I'm more looking for direction that actual code answers!
First, I want to use display a clock in my applicatio that uses an atomic clock to sync its time with. What is the recommended way to do this/links to useful info?
Second, I also need to display the time of other timezones, say I'm in LA, and want to diplay the time for London and NY. Does any body have links to information on how one would go about determing the time in other timezones,area. My biggest issue is with how the user can pick his location and how the software knows the timezone/etc at that location?
Many thanks in advance,
Mark

Hi
I'll only comment on the second part of your question. You'll have to enumerate the time zones and their offsets from a reference zone (eg. US Pacific time is -8 hours from GMT) and then apply that to what you believe the time to be in the reference zone - eg. if it's thought to be 10:23am in London (GMT being your reference zone for example), assume it to be 10:23am - 8 hours in California, and so forth.
Roughly it means that if you change the time on the London machine, the times in all the other zones change.

At the moment I have a Menu Resource with a "Languages" so when a user clicks it, it will change the language to whatever they select, However its all typed in the resource.
What i've been trying to do is get it to scan the /languages/ folder and add item's to the menu acordingly..
I'm not sure if this is possible with WTL or not? and if it is how would handle the clicks?
Thanks..

I Have two buttons on a form, when i click one i want the other one's style to change to WS_EX_STATICEDGE
I've tryed using:
CButton m_Ok;
m_Ok.Attach( GetDlgItem(IDC_TEST) );
m_Ok.ModifyStyleEx(0,WS_EX_STATICEDGE, 1);
m_Ok.Detach();
On the click of the first button, but it doesn't work.. How would you do this (if you can?)
Any Help would be greatly appreciated, Thanks.

Hi,
I am building a simple deskbar.
The deskbar consists of a toolbar as its main window.
On this toolbar is a edit box window, and next to that a toolbar with a single button with the combo-box drop-down style.
The toolbar window class is:
class CMyBar: public CWindowImpl<cmybar>
{
public:
DECLARE_WND_SUPERCLASS(TEXT("MYBAR"), TOOLBARCLASSNAME)
...
}
The problem is when the mose is not hovering over this toolbar button, its background is always rendering black. In practice of course I want it transparent, so one sees the toolbar below it.
I tried applying the style
DWORD dwStyle =
/*Window styles:*/ WS_CHILDWINDOW | WS_CLIPSIBLINGS | WS_VISIBLE | WS_CLIPCHILDREN | WS_TABSTOP |
/*Toolbar styles:*/ TBSTYLE_TOOLTIPS | TBSTYLE_FLAT | TBSTYLE_TRANSPARENT | TBSTYLE_LIST | //TBSTYLE_CUSTOMERASE |
/*Common Control styles:*/ CCS_TOP | CCS_NODIVIDER | CCS_NOPARENTALIGN | CCS_NORESIZE ;
but this makes no difference what so ever.
Does anybody have any ideas how I could stop this from happening?
Thanks in advance,
Mark

Can somebody explain the following construct and when would you use it?
GetSize().foo = NULL;
thanks...

When GetSize() returns a reference to an object, and .foo is a pointer?

Thank your Jorgen,
Could you show me a sample of how you would set that in a class and its use...
Thanks again...

Hi all,
I have developed a ATL in-proc server (dll) that exposes some COM objects, and these have some events. I have to fire events in a separate working thread I spin when the library is loaded. So the event consumer is serviced in another thread. When I use this in a VB6.0 application all works well but if I attempt to debug the event, placing a breakpoint in the event sub, the breakpoint is hit, but then the VB IDE crashes and suddenly disappear.
I registered the COM object apartment as BOTH.
So what is the problem?
Could you please help me?
Many thanks and HAPPY NEW YEAR !!!!
Regars,
Andrea

In short : The interface pointer used by your worker thread to fire the events is not valid for the worker thread.
In length (there are numerous resources on the web that discusses this problem):
http://www.mvps.org/vcfaq/com/1.htm[^]
It's doesn't matter that the object is martked 'Both'. VB instansiates it in an STA.
In detail: When you fire the event in your worker thread that thread executes native VB code. VB assumues that the thread that calls it is always the same thread (the same requirement as for the STA). VB tries to get data in the TLS but since it is the wrong thread that calls VB, VB will sometimes throw access violation (if you're lucky).
If the object would've been marked 'Free' (an MTA object) then VB (or rather the COM-runtime) is forced to instansiate the COM object in the MTA. If the worker thread then also enters the MTA (by calling CoInitializeEx with argument COINIT_MULTITHREADED) then it's legal for the worker thread to fire the events in the way the VC 6 wizard generates the event-firing code. In this case COM will automatically put up proxy/stub pairs between the VB and your object ensuring that it's the correct thread that calls the VB code.
The drawbacks are:
1. Performance (every call is marshalled and will force a thread switch, few calls = no problem, many calls = large performance hit)
2. You must secure your object for concurrent access (but since it was marked 'Both' it should've been secure already
3. An MTA object _can not_ be an ActiveX object (that is a COM object with UI)
A peculiar detail is:
1. When the VB code calls your object the COM runtime will pump the message loop.

1. If I load a web page that contains frames then the OnDocumentComplete() is hit for each frame. How can I recognize that the page is completely loaded (no more frames missing)?
2. How to recognize that web page is redirecting?
