Not if you do your operations in a seperate worker thread, and leave the UI thread open to talk to the system. If you're using MFC, it's as simple as AfxBeginThread()...

But if I respond to WM_ENDSESSION the application will end.

I designed a small activex control with a Property page. The property page has a button control.
Suppose if a place this control on a Dialog Box by right clicking on the Control and selecting properties..., it displays the property page with button control. when i click a button the focus will change to ActiveX control window , where i can draw using mouse .
Any help ...
Thank you.

huh???  Are you asking how to do that just telling us you already do? Do you want to draw, like MS-Paint draw, or draw as in an owner-drawn menu?

There is an article here on CP about setting the project to build debug but think it's release.
Otherwise you can use messageboxes to figure out where you are crashing, or a log file.

You may have a stray pointer there. Look at the memory address: 0x0000003c is certainly not a real variable adress.
You are having this error in Debug build also, but it is masked by some of the error-correction mechanisms there. Look for mentions of memory leaks when executing your Debug-build.
You are positively sure that every pointer you are using has been initialised and checked for validity before?
This can only be a starting point, but (as Christian said) there is an article about this on CP

If you cannot recreate in debug mode, perhaps you should throw in some message boxes to see exactly where the error is occurring. Once you narrow it down maybe you can figure out the problem.

How does 'GetVolumeInformation' and
'GetDriveType' sound ?

Hey all, in my view class i have it create a Object of mine that uses a thread to complete it's task, when the thread finishes it users AfxGetMainWnd()->PostMessage(MY_MESSAGE, 0, 0); to post a message. I am trying to catch it in the view class with ON_MESSAGE(MY_MESSAGE, MyFunction) but no luck. tho if I put that in the MainFrame class it catches it. Any ideas on how to get the view class to notice this message?
thanks in advanced.
Luke.

OK, It's something like this, the Message Pumps are associated with a
thread and not a window. Inside this thread the messages are dispatched
to different windows based on the windows handles.
So your code is posting back to the same thread which does not
have a message pump (while(GetMessage(..) {...}) so what ever messages
you post will never be executed!
Now you have two options
1. Post the message to the main thread and have it executed there
by using PostThreadMessage.
2. Provide a message Pump (this will mean you will need to re-tailor
your existing thread function to use the message pump and not
the simple while)
Hope this helps..

Post a user-defined command instead with AfxGetMainWnd()->PostMessage(WM_COMMAND,MAKEWORD(0,ID_YOURCOMMAND,0); and add an ON_COMMAND handler to your view: the MFC framework will properly route the command to the view handler.

hi all,
please tell me how i can change the color of Mainframe,like scrollbars.
thanks

Have a look at GetSysColor/SetSysColors which
change the whole systems colors(which is not
exactly a good idea!)
The next thing is to go in for painting the non-client
areas(ex the title bar is non client area) for
some of the things and for others you need a
custom control.

I have got a desktop app written in VC++ 6.0.(MFC support) Now I have to convert it to an Arabic version. Can somebody help me know what are the steps involed in such a conversion process? I tried to create an Arabic resource using VC resource editor but didn't succeed !! Do I need to have Arabic Windows for that ? Any help on this is highly appreciated.
Thanks in advance.

I wrote an article that might help:-
http://www.codeproject.com/cpp/mult_lang_support.asp
I have always converted to European languages, there is a trick you can use the method is described in the article, basically you would need a copy of Visual C++ tha is in the language you are convering to, or convert all the text in the .rc scripts.
One of my freeware progs was converted to French this tool about a mornings work, but it did not have a lot of text to convert, and neither was teh help file converted.

Besides the usual of putting the application in UNICODE ( with UNICODE and _UNICODE in the settings ).
I don't think you need that, you simply need to set the locale/regional settings to arabic ( of your country if applicable ) in one of the control panels, and you also need to change the keyboard settings tu use the IME ( I only did this for oriental languages ) to type the Arab characters.
When changing the resources, you can't simply copy the files, and type in arabic, you need to change the language section of the RC file. The resources are not UNICODE, they are in code page, that's why you need to change your locale/regionale for it to work.
for example in english we have this :
#if !defined(AFX_RESOURCE_DLL) || defined(AFX_TARG_ENU)<br />
#ifdef _WIN32<br />
LANGUAGE LANG_ENGLISH, SUBLANG_ENGLISH_US<br />
#pragma code_page(1252)<br />
#endif //_WIN32
you'll need to change the language, sublanguage and codepage.
Good luck!

I've set up a server using winsock, and it accepts

I know it must be possible, but I'm new to this
so thanks for any help!

I'm going nuts. Not a particularly arduous trip, given my starting point, but not pleasant in any event. I'm doing a trivial app ( for the rest of you, not me ) to add CDs to a database. As the primary input screen I have a dialog box that allows 16 rows of input, selected because I don't have any CDs that hold more tunes than that. In each row I have a group of radio buttons to indicate whether each track is a solo, a duet, or a group song. The first button of each row has the Group property set; the other two do not. In all other respects every button is identical, and this pattern is consistent for all rows.
When I compile and execute the code, row 8 interacts with row 9, though all other rows behave exactly as I'd planned. Row 8, by itself, works great, but when I select the second button in row 9, the third button in row 8 clears instead of the first button in row 9! Selecting the third button in row 9 clears the first in that row, but the second is unaffected.
I thought I had a clue when I discovered that the numerical order on the defines for the buttons was a bit skewed for these two rows, so I edited them to follow the proper sequence and saved the whole project. But after rebuilding all, the behavior persists! Suggestions would be most welcome - I'm out of ideas!
