I'm not certain I understand correctly what you want to achieve.
I don't have iTunes in front of me; and I don't see what you mean by "clicks on a button at the right panel".
Me think it's quite moronic to call DoModal() recursively.
If you want to create and display N dialogs M number of times, you'd better
use modeless dialogs and be conscious about managing the memory (when you
create and destroy the dialogs).

No I dont want to use modeless dialogs. I will try with Ian suggestion and get back to you all.
Thanks.

Make the use of LVN_ITEMCHANGED notification.

Please handle LVN_ITEMCHANGED[^] message. When a selection change occurs in the list control, the parent dialog/window will get a LVN_ITEMCHANGED message

Hello,
thanks for answer and i hope its ok if i answer here to naven only??
Yes this works fine, and easy to implement this funktion!
Only one funny thing is now in execution of program, this LVN_ITEMCHANGED is send 3 times?? Also my function i called 3 times??
Here my code:
ON_NOTIFY(LVN_ITEMCHANGED, IDC_LIST, &CMyDialog::OnLvnItemchangedListAll)
void CMyDialog::OnLvnItemchangedListAll(NMHDR *pNMHDR, LRESULT *pResult)
{
LPNMLISTVIEW pNMLV = reinterpret_cast<lpnmlistview>(pNMHDR);
int iCurIndex = m_cListAll.GetSelectionMark();
CString csItemText = m_cListAll.GetItemText(iCurIndex, 1);
TRACE(L"%s\n", csItemText);
PrintData(csItemText);
*pResult = 0;
}
</lpnmlistview>
So is in output the same text 3 times listed  , for example if i have text in my current selection: www.codeproject.com
they is dump three times , any idea how to avoid this(if possible  ), or is this common property??
But this is that what i'm looking for!
Thanks for help!

That is because the notification is sent for different states. You can check the new and old state flags in the "LPNMLISTVIEW pNMLV". And if the new state is selected and old is not selected, then proceed it.

Its ok. I will inform ns.ami cause he is my friend and we both work in same company
termal wrote: Only one funny thing is now in execution of program, this LVN_ITEMCHANGED is send 3 times??
Yes this is because, the LVN_ITEMCHANGED is fired not only for selection change but also for foucs changes. So you should check, whether the current LVN_ITEMCHANGED is for selection change or not.
NM_LISTVIEW* pNMListView = reinterpret_cast<NM_LISTVIEW*>(pNMHDR);
if( LVIF_STATE == (pNMListView->uChanged&LVIF_STATE) )
{
if( LVIS_SELECTED == (LVIS_SELECTED&pNMListView->uNewState) )
{
}
else if( LVIS_SELECTED == (LVIS_SELECTED &pNMListView->uOldState) )
{
}
}

I have an application, where i open the private Queue. This works fine.
But when I run this app as a windows service, it gives an error failed to open the Queue, Access is denied.
I know it has got to do something with the rights.
If the app is run as an exe, it will have the logon credentials. When run as windows service it will run with System credentials, which may not have access to Private Queue.
How do i enable my windows service to have access to the private Queue???
Any help will be great.
Thanks,
Saleem

Did you try setting the Log On Properties for the service to use the same account as the queue?

Hello everybody,
is it possible to determine at realtime the function which has called the current function?
Example
void A(void)
{
DoWork();
}
void B(void)
{
DoWork();
}
void DoWork(void)
{
char *trace = GetTraceOf5LastFunction();
OutputDebugString("DoWork called from function : ");
OutputDebugString(trace);
}
Is it possible?
Big thanks for any help 
Edit:
I have found a fonction called "backtrace" which is placed into execinfo.h
But i don't have a such header-file on my system (Visual Studio)

Can you use of dll's you can load your functions of dll on the current function.

Is there a DLL which executes the work of backtracing?

Hi,
the easiest way may well be the low-tech one: add a string parameter to the function, and pass the caller's name. That works no matter what.
DoWork("A");

This method is the simplest, but i can't write over 100 Debug-Lines into the code
But thanks anyway

Hi baerten,
I agree with Luc. However you may be able to use a pre-defined macro[^] something like below:
VOID FunctionB(int iVal,char *caller,int line)
{
char szBuf[MAX_PATH];
sprintf(szBuf,"I was called by %s on line %d",caller,line);
MessageBoxA(NULL,szBuf,0,0);
}
VOID FunctionA()
{
FunctionB(1,__FUNCTION__,__LINE__);
}

A stack trace is several times more expensive at runtime.

You need a stack walking function. Here are some[^] links[^] that may be useful.
The second is probably best - John Robbins is a well regarded expert on debugging and things like that. His SUPERASSERT code includes stack tracing code - see the dialog screenshot about half way through the article for an example of what you can get. Obviously you only need the last item in the trace.
One last thing - IIRC, without debug symbols, all you're going to get is the address that called you, not a function name.

You can use of CDatabase class and see this[^] example.
