Hello,
I wrote a com object in C++.ATL.
I did a small header file for general definitions.
When I include that file in other classes I got error such as missing ; etc
example of the header file:
#ifndef __LIC_T_H
#define __LIC_T_H
#include
using namespace std;
#define FILE_BUFFER_SIZE 100
#define ENCRYPT_ELEMENT_NUM 4
struct Lic_t
{
};
#endif
thanks

include stdafx.h as the first #include statement int he header file or disable using porecompiled header file in the project settings.
cheers...milton kb.

I need to marshall an interface to a apartment threaded component.The component has type library marshalled interface(oleautomation).
I plan to use CoMarshalInterThreadInterfaceInStream/CoGetInterfaceAndReleaseStream(IStream) based marshalling ,but it cannot be sent across as void*(not automation-compatible datatype).
Is there some way to marshall this interface without using GIT?

What does this mean? 
"across" what?
If you mean across apartment boundaries it doesn't matter whether the interface is automation compatible or not.
If it's an interface method that takes an interface pointer it should be passed as an IDispatch* if the interface is automation compatible which means it should not be cast into a void*.
What are you trying to do/call that requires a void*?

Sure, CoMarshalInterThreadInterfaceInStream/CoGetInterfaceAndReleaseStream is the way to do it.
It's supposed to be hard, otherwise anybody could do it!

Hi all,
I have customized controls for button(ownerdrawn), listbox, listctrls, etc. They were intended for MFC applications. They are working fine in MFC dialogs in ATL.
But when they put directly in ATL composite control, there are many painting problems. Button is not getting painted (a gray rectangle can be seen). List box and list control are painted as default.
What could be wrong? Or is there any limitation between ATL and MFC connectivity?

Have you tried the REFLECT_NOTIFICATIONS() macro in your message map?

Yesterday there were some progress... Yes, I used REFLECT_NOTIFICATIONS() macro. I read in MSDN that there is some changes in messages. For eg., instead WM_DRAWITEM there is OCM_DRAWITEM, etc. So I tried to map this message to drawing function in Button class. Then the button worked fine.
Now my doubt is that,can I map all these OCM_ functions permanently? I need to use the controls in both MFC and ATL based applications without changing the code.
Thank you.

Can't you just have two handlers (eg. for WM_DRAWITEM and OCM_DRAWITEM) that point to the same function?
You can dig around atlwin.h to see how the reflections are done.
OCM_DRAWITEM = WM_DRAWITEM + OCM__BASE

OK. I understood. I have to try it. Thank you.

How do I find out which version of ATL and WTL is installed on a System? Is there a way?

WTL can't be installed, it's just header files.
For ATL, you can look at the version of atl.dll. But apps can be compiled with ATL code staticly linked, so again there's nothing that is installed.

Oh, you mean when compiling. Ok, the versions are in the _ATL_VER and _WTL_VER symbols.
Use the MinDependency build targets to staticly link ATL.

If you use ATL control containment you need "ATL.dll" even if your statically linking.

How to add Timer in activex ?
BEGIN_MSG_MAP(ClistSample)
MESSAGE_HANDLER(WM_TIMER, OnTimer)
END_MSG_MAP()
LRESULT OnTimer(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled)
{
return 0;
}

I believe you will need a Window to get timer messages. It doesn't work in window-less controls.
1- You could use the Multimedia timer.
2- Or you could just create a hidden window that would receive the timer messages.
3- Or create a thread that sleeps for the specified amount of time, and calls a function of your program. (quite inaccurate timing).
this is this.

You need to start the timer.
UINT nMilliseconds = 1000;
::SetTimer(hWnd,ID_TIMER,nMilliseconds,NULL);
when finish stop it with
::KillTimer(hWnd,ID_TIMER);

hi,
i've a view on which i have some CComboBox, and 1 CComboBoxEx (class extending CComboBox with some cool things).
i'm setting the background color and the text color of the CComboBox by handling WM_CTLCOLOR messages, and here is some code:
LRESULT MyView::onCtlColor(UINT , WPARAM wParam, LPARAM , BOOL& ) {<br />
HDC hDC = (HDC)wParam;<br />
<br />
::SetBkColor(hDC, WinUtil::bgColor);<br />
::SetTextColor(hDC, WinUtil::textColor);<br />
<br />
return (LRESULT)WinUtil::bgBrush;<br />
};
this does color all the controls of my view succesfully, except the CComboBoxEx ! For this control, the background is set on the whole control except behind texts; moreover, the texts don't get colored. Here is my problem, if anyone has some clues, it would be great  ! (since Google didn't have any  )

Hi All,
I want to create a button on a HTML page. When I am clicking the button, it should trigger the Browser Helper Object event, and should execute the code written inside the BHO event. BHO events written in VC++ ATL.
Expecting your valuble suggestion.
