Re: Window handle in Active-x in ATL

14-Dec-04 14:37

I have a active-x ATL control. Inside my control I want to use InvalidateRect(), but I can not because it is not a window. Even I do I get Assert letting me know that it failed, because it is not a Window or no handle for the Window. What I am looking that how can I get the handle of the container. In my case it is a dialog Box.

Looking help I found this example. (
ATL Library Reference
CComControl::CreateControlWindow
)

RECT rc = {10,10,210,110};
HWND hwndParent, hwndControl;

// get HWND of control's parent window from IOleInPlaceSite interface
m_spInPlaceSite->GetWindow(&hwndParent);
hwndControl = CreateControlWindow(hwndParent, rc);

Here I am lost. How we can use IOleInPlaceSite to get the Window Handle.

Or if you have any other idea.
Your help will be very much appreciated.

Best regards,

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? Confused | :confused:

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.

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.

What's the best way

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.

ATL / IIS / EXE ???

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?
