Hello,
I'm working on a project in which the user will click on a directory, and this app will grab all the files in the directory (and all subs), parse their names, and create a new CList.
Are there any helpful MFC code and/or resources gathering the files in the subdirectores?
thanks!

Check out the CFileFind class.

Perfect! Thanks!
Would you happen to know how to get MP3 information as is built into XP (e.g., encoding rate, etc.)?
thanks!

I would suggest studying the file format. It's available at www.wotsit.org.

Good time of day!
 Please, help me to solve my little problem
I created split window with two views.
<br />
<br />
BOOL CMainFrame::CreateSplitters(int nRows, int nCols, int m_actRow, int m_actCol, CCreateContext* pContext)<br />
{<br />
m_bInitSplitter = FALSE;<br />
my_RightView = RUNTIME_CLASS( CRightHTMLView );<br />
my_LeftView = RUNTIME_CLASS( CMyTree );<br />
CRect cr; <br />
GetClientRect( &cr);<br />
<br />
<br />
.. <br />
if ( !m_wndSplitter.CreateView( 0, 0, my_LeftView, CSize(width/5, cr.Height()), pContext ) || !m_wndSplitter.CreateView( m_actRow, m_actCol, my_RightView, CSize(4*width/5, cr.Height(), pContext ))<br />
{<br />
...<br />
} <br />
...<br />
}<br />
<br />
But I need two create split window dynamically, 'cos later I'll need to destroy it and create another two views (but with gorizontal locating)
Please, help me.

Why not try splitting the OR into two statements? You may be assuming a boolean short-circuit that isn't occurring. So it's calling CreateView twice, not once.

I need to develop a messaging system for my dialog based appication and wanted some pointers on the approach to take. My need is as follows.
1) The main application would be the central control hub of all messages.
2) Plugins would subscribe to messages that they would like to recieve
a) keyboard presses
b) volume up
c) next ( next song event for media player )
d) etc.
3) The subscriber could possibly send a response to the recieved message.
4) Everything would be done as a result to a recieved message.
5) The subscriber should not have to scan for messages just get them and either process it
or ignore it.
Hope that make sense.

What about the Observer pattern ?
I don't know if it can be adapted to be used with plugin.

I am not familiar with the observer pattern. Do you know any of code examples or links
Thanks

Well I researched the Observer Pattern and that is pretty much how I talk to my plugins.
To me it is just more or less interfaces COM style.
What I am more interested in is the actual message passing itself.
The message could be any of the following:
1) Play was pressed. (STATE)
2) Send me the play list (List of strings)
3) etc.
Thanks

I am at an intermediate level in Win32 programming and am looking to master the Win32 API. Do you recommend Petzold's book Programming Windows, or the Newcomer book Win32 Programming?
Thank you for your help.

Never heard of the new one, but Petzold's "Programming Windows" is a must have.

The Newcomer book is a lot of MFC/C++, Petzold deals more directly with the C api's.

Thanks everyone for your input.

Need a bit of help please 
I'm coding a tool that creates iso files from cd/dvd disks, all was going well until I tested on a dvd disk (cd disks work fine) but for some reason the program cannot read direct from the dvd.... I know the code works as it reads direct from the cd in the same dvd drive as I tested the dvd disk in. I also made sure windows was able to read the dvd correctly to rule out a damaged disk.
What I need to know is, is there some kind of extra 'unlocking' routine or something that needs to be performed before I have access to the dvd
I should also mention the dvd in question is not a dvd movie disk, but a dvd data disk created originally with nero.
Any help on this will be appriciated.

I want to show dialog window (with image) for 3 seconds befor my project will start.
I use Timer with aim to destroy dialog window in 3 seconds
<br />
<br />
BOOL CRightHTMLView::PreCreateWindow(CREATESTRUCT& cs)<br />
{<br />
<br />
dlg = new CDialog(IDD_ABOUTBOX, this);
<br />
MSG message;<br />
int i=0;<br />
m_nTimer = SetTimer(1, 100, NULL);
ASSERT(m_nTimer!=0);<br />
if(i==0)<br />
{<br />
dlg->DoModal();<br />
if(::PeekMessage(&message, NULL, 0, 0, PM_REMOVE)) {<br />
::TranslateMessage(&message);<br />
::DispatchMessage(&message);<br />
}<br />
i = 1;<br />
}<br />
return CHtmlView::PreCreateWindow(cs);<br />
}<br />
<br />
void CRightHTMLView::OnTimer(UINT nIDEvent)<br />
{<br />
Sleep(3000);<br />
dlg->DestroyWindow();<br />
KillTimer(1);<br />
<br />
CHtmlView::OnTimer(nIDEvent);<br />
}<br />
<br />
What is wrong in my function(s)? If anybody knows how to display image in other way (not in dialog window), please
share here with your ideas. I would appreciate your co-operation.
Aleksey.

In PreCreateWindow() your window hasn't been created yet (thus the "pre" in the name) so you can't do things like set timers or pump other messages that rely on window handles.

The program find min and max from all numbers in file, but not only from 100.
It must be able to do that with long txt files too, and each 100 numbers is work with number (1. work(for first 100 num), 2. work(for secund 100 num),...)
Where I am doing wrong ? Please, help me !

If there are more than 100 numbers in the file, you'll need to change the value of MAXELEMENTS. A better solution would be to use a dynamic array. That way you do not have to keep changing and compiling code when the size of the input file changes.
