By chance are you intercepting the WM_QUERYENDSESSION message?

Hi,
I have created an OpenGL window and can draw on it fine in the same thread as the one that created the window and processes the message queue. If I move the gl code to another thread, it does not draw anymore.
Does anyone know if this is possible?
thanks,
Rich

From what I've read in every place I've seen, this doesn't really work, as in drawing from one thread into another thread's hwnd, at least it's not supposed to be done that way. And from my own attempts to do it before I read it windows handles got quite mixed up in the process and nice amount of asserts in MFC code. But as I wrote this was basic MFC app and cannot vouch it is totally true for you.
Basicly what you would do is do the work in a thread and message the window owner to do the drawing with the params you calced.

Hi everybody,
i'm trying to export a variable (integer) from a c++Win32 Dll to VB.
Later on an enum and a class !
Exprting functions is no problem but the rest !???!
Could you explaim what the .def file and the Vb code have to contain (code).
Btw. do you know good books or tuts which cover these problenms ?
I only have heared from this book :
"Professional ATL COM Programming" von Dr. Richard Grimes
thanks very much for your help

classes?
I think you have to go through COM and export interfaces rather than instances of classes.

Hello,
What is the best way to export/save list items from a CListControl to file?
To read list line by line and export to file can be slow if i have many items in list, right?
I expect to have more then 50000 items in list, and there are 24 columns!
Please give some suggestion about this problem!
Thanks for any help!

IMHO, there is something wrong with your design. The list control should be used only to display information, not to store it. Typically the data is stored somewhere in your document class (in case you are doing a SDI application) and is only displayed in the list control.
So if you want to save it, you don't interract with the list control.
If possible, try to separate the 'logic' and data storing from the way it is displayed.

Hi,
thank you for answer, i undersand what you mean!

BTW, if you need to insert so much data in your list control, it will probably be quite slow. I think (I'm not sure because I don't use this control a lot) that you can use a virtual mode. Instead of putting all your data into the control, you let the control ask your program what to display. In this way, only what is currently visible will be 'asked' by the control which should be faster.

You can use of a thread or timer for read and insert values to listctrl and you can use of CFile for save these values.

Some Windows filestore-explorer-type folders have on their left edges a displayed tree of folder and file names. The nodes of this tree can be collapsed and expanded by clicking on the node points.
Please, is there a function that I can call to make such a tree (not necessarily of folders and files) appear in a Windows program that I write?

MFC enabled developer? Go through CTreeCtrl class [^].
No MFC? Use Tree View API [^].

You want to use of CTreeCtrl,and if you search on the codeproject you can find customize treectrl.

In TEST.dll, I've some methods like method1

Many thanks in advance
Hope to hear the help soon.

Hello everyone,
Reading from book Windows Internals, we should use private bytes to monitor memory leak.
1. I think the reason why not using virtual bytes, is because there may be some shared materials counted as a part of virtual bytes -- like shared library and file map;
2. I think the reason why not using working set, is because sometimes working set is trimmed and sometimes not all committed virtual bytes are in working set -- like demand for zero scenario.
Are my understanding for (1) and (2) correct?
thanks in advance,
George

By chance have you asked either Dr. Russinovich or Mr. Solomon if your understanding of their book is correct?

Thanks DavidCrow,
I have read the section of memory management, and it is only mentioned using private byte to monitor memory leak is correct. I want to do further analysis why using other parameters, like virtual bytes and working set to monitor memory leak is not correct to verify we truly understand the points of memory management.
It is appreciated if you could share your points.
have a good weekend,
George

Now do you check private bytes for monitor emmory leak what was result?

Thanks Hamid,
In my limited testing, private bytes keep increasing if there is memory leak, but I am not sure whether the general rule applies for all scenarios. It is appreciated if you could share some of your points.

George

Do you want to find memory leak of your program or all programs?
|

Only my program is ok, Hamid!
Any ideas?
