If you're dealing with window less controls, take a look at the IOleInPlaceSiteWindowless interface. Query m_spInPlaceSite for IOleInPlaceSiteWindowless, and use the InvalidateRect() function. Not that I've ever written any window less controls, but from what I can tell, this seems to be the correct way to invalidate rectangles.

Dear Jörgen Sigvardsson:
Well I am NOT writing Windowless control. Perhaps you have noticed that regardless it is Window control or not IOleInPlaceSiteWindowless is implemented. Bottom line is it does not work. I will let you know as soon as creak it.
Thank you for your prompt reply.

I don't get it. Didn't you say that the control had no window?

Yep. That's because the code can handle both windowed and windowless controls, and it can even configure itself at runtime. IIRC, there's a member variable called m_bWindowless or similar that controls that behavior.

Hello everybody,
I am creating a dll that contains some
Methods and these methods have some styles like:
#define dw_style 1401
After importing my dll and calling that method I want to
Use this dw_style name instead of 1401.
In another word I want a global #define.
////////////For example/////////////////////////////
//In the Dll file
#define dw_style 1401
..
methods
..
////////////////////////////////////////////////////
//////////In the mfc app and after importing the dll
method(dw_style)
..
..
Best Regards
Thanks.

The answer is also very simple. As we know that define just replaces the actual content what we have defined. It CAN NOT be exported.

YEah you are write but what about ENUM in Com DLL.

enum are more like constants whereas #define are macros that get expanded during compilation time.
I hope you will get what I am saying
Have a great day ahead!

export them is not suitable. you can define them in the header file.
when you use the dll ,you can include the header file first.
Happy new year!

How can I use a timer in my DLL?
Best regards

you can create Hidden window in your dll that will handle the above cause

I'm developing a multithreaded application mix of MFC & STL stuff using MSVC and having so many DLLs integrated in it .
I have very small question. I want to have little structure(about 3 elements ) associated with each thread and needs to be exported to all DLL in system.
So what's the best way to implement by having simplest old way to have a array of structure/class or have list/map template of structure/class.
Can someone please suggest the best way to go ?
thanks
ben

It is such a simple question, perhaps I am not following. You may pass any data to any thread even a whole class or more and inside that class cast to that struct or class. By nature all thread functions are static so you have to cast incoming data to desire class.

howdy all-
My current problem: I've got this ISAPI DLL, which does some stuff and generates XML. It's written in C++, uses MSXML3, and run's inside DLLHOST...
Oh, and it leaks memory.
(1) Is there a good way to debug this?
(2) If I could convert this to a stand-alone exe, I could attach a debug memory manager.... Can this be done -- can I make an ATL/IIS server extension which is also an exe. (is this what's called an out-of-process server?)
Thanks in advance!
Regards
-peter
P.S. I think I do ask some of the more esoteric questions on this site.... I hope someone has some help or direction for me. Thanks

Compile a debug version of your DLL and attach your debugger to DLLHOST.exe. Debug as usual.

oh...
I wish it were that simple....
But tracking memory leaks is the real problem...
and it's not MFC....

I'm not sure I understand what your getting at. You asked "Is there a good way to debug this?". I explained how to do this. Why is it any different to track memory leaks in a dll? What does MFC have to do with anything?

Forgive me for my ignorance in this arena.
It's code that was kinda thrown at me, and finally given all responsibility to figure out.
I'll be more specific. It's an ISAPI DLL which mines data out of our servers, generates some XML and passes it back to IIS for display.
Upon repeated use, it leaks memory...
My attempts to locate the memory leak are failing, and i am flailing 
Maybe you could tell me the best way to detect memory leaks in a situation like this?
Thanks

Thanks for the reference.
I've always wondered where that came from. It's something you get by default using MFC. (that's where my MFC remark came from).
Anyhow -- thanks

Some memory leak tips, start looking for misbehaving BSTRS, unreleased components and unfreed mallocs.
Also you can use the perfmon and taskmanager to monitor the memory as you debug...

I should assert here that I undersand the basics of memory leak issues. But I need "special help" in the area of an IIS addin (ISAPI DLL).
What's special about this kinda of app, is:
* you write a dll
* it get's loaded either directly by IIS (inetinfo.exe)
* or indirectly via DLLHOST
* you don't have much control of the environment
All of the standard memory leak issues are covered.
* balancing a delete for every new
* releasing COM stuff
The unknowns are:
* ISAPI DLL issues
* BSTR's
* MSXML3 memory issues
