The trick here is to remember that debug asserts are your friend. Let the assert happen and use the debugger to examine the line that asserts. If it's deep in MFC (probably is) there are probably comments in the source explaining what's being asserted and why it might fail. It's those conditions you need to investigate to deal with the assert.

You are thinking of a "wizard", I think.
Look up CPropertyPage / CPropertySheet in MSDN documentation. Or look in the Programmers
Guide section for something like "programming a wizard".

and winzip

that will change accordinly
to what version of windows the user is using like this

You could create a new class for you button and catch the message WM_MOUSEMOVE, setting there a boolean value according to the position of the mouse, and modify the drawing according to this boolean value.
You may find useful info in this article: CButtonST v3.9 (MFC Flat buttons)[^]

To my understanding, a CD has 0's and 1's (binary) written on it, and a laser reads the binary. Then the computer translates it. Please correct me if I am wrong. I am using MFC, and what I am trying to do is get all the binary data off of a CD, and put it to a char. Is this possible? Any help at all is appreciated.

a CD has nothing "written" on it!
there are pits and pats (or whatever they are called... dunno).
a change between pit and pat is a 1, if it doesnt change then it is 0.
to read the binary sectors from a CD you will need IOCTLs or even better SCSI.
IOCTL_CDROM_RAW_READ is the IOCTL, but i dont know if you will find it in MSDN, my doc is part of the DDK.
if you want to use SCSI then have a look at CDex src.

Im makin a program that will respond to system restart and shutdown and i want to know how to idnetify shutdown from restart.
on WM_QUERYENDSESSION:
how do i know if the application is shutting down or making a restart?
What is the value of lParam parameter for shutdown and restart?
be glad if anyone would answer. 
|
|
|
|
|
you cant get this information from WM_QUERYENDSESSION.
it just tells you, that you app will be closed and if it is just the user logging off.
Don't try it, just do it!
|
|
|
|
|
any idea where can i get that information?
|
|
|
|
|
no, why is this information interesting for you?

im makin a program that should react only on user shutdown.
|
|
|
|
|
and what does this program do?
Don't try it, just do it! 
|
|
|
|
|
well its just a simple program. it will just post a messagebox( reminder } on every shutdown and that reminder should not appear during log-off and restart sessions.
got any idea how to do it besides trapping the WM_QUERYENDSESSION message?
|
|
|
|
|
The net result of both a shutdown and a restart is the same (i.e., memory has been flushed, data has been written to disk, programs have been closed). The fact that it came back up with a restart should be irrelevant. However, without more details of what you are after, it's hard to suggest a more elegant solution.

well i have this program that remains hidden and be shown when shutdown is detected. my problem is that it should not appear when the system restarts or logs off.
well logoff and shutdown can be detected on WM_QUERYENDSESSION and WM_ENDSESSION.
in what way or how does windows commands the system to power up again after shutting down ( restart ).
do you have any idea on how to accomplish it?

I have a program where I create various objects in mainframe. The objects are data members of class mainframe. I need to access these objects using member functions in dialog and view.cpp. How can I access objects in mainframe from dialog and view? Right now I am using a Extern to do it, but I dont like doing it that way.
Can someone give me a few ideas?
Thanks.
Jerry

use
CMyMainFrm *pFrm;
pFrm = (CMyMainFrm*)AfxGetMainWnd();
pFrm->{access the member functions or variables}
This space is empty.

I have a cmainframe in my project, but when I do the following:
(cmainframe is derived from cmdiframewnd)
cmainframe *pframe = (cmainframe*)afxgetmainwnd();
in a function that is part of my view.cpp file...
it doesnt recognize cmainframe

What error do you get, if you are getting any?
The Logic should work without any probs.
This space is empty.

I think I know what I did wrong, thanks. The compiler did not recognize the cmainframe object. I needed an include statement.
Thank you very much.
