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...
Happy New Year...

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?

I tried this in my application but it doesn't seem to work. Did get it to work though by checking the iDispath parameter of the webbrowser with the one fired. But the problem came in certain pages when the top level frame does not fire a documentcomplete. does anyone know how to get over this??
Thanks,
Arun

Greetings,
I am porting existing MFC based ActiveX controls to ATL based ActiveX controls which support MFC internally. I am using Visual Studio 7.1 and in this version MFC has aparently been merged with ATL. However I am getting compilation errors for some of the MFC based functions.
For example,
TranslateColor(), GetBackColor(), and GetForeColor() all give the following error:
"identifier not found, even with arguement-dependent lookup"
If MFC is merged with ATL then why don't these MFC functions get recognised?
Has anybody come such a problem? How does one get the compiler to understand what these functions are, or what the equivelant ATL functions are?
Thanks!
