are you opening your second dialog from some worker/secondary thread.
IMHO, you can never operate on firt dialog if second dialog is open as model dialog!

What happens if, in the second dialog, you comment out the thread-creation code? In other words, you have one modal dialog opening another.

Hi everybody
I am having a small querry
int * p = new int(10);
int a = 10;
int * q = &a;
then to delete pointer p
delete * p;
Whether pointer q is also created on the heap.
If so how to delete it?
Is q = NULL is correct?

It's like:
delete p;
Deepu Antony wrote: Whether pointer q is also created on the heap.
Nope, heap allocation occurs only when you use any of the heap allocation functions (new, calloc, malloc, etc.,)
Deepu Antony wrote: Is q = NULL is correct?
No. q has the address of the variable a. And can be pointing to some random value if you hadn't assigned it like that.

No, q is not allocated on the heap. It just contains the address of a, you didn't allocate anything for it. Keep in mind a very simple rule: for each call to new, you should have a matching delete. No more, no less. In this case, you have one single new (for the p pointer), so you have to call delete on this pointer, and that's it.

If the momory pointed by q (pointers are ususally created on the stack) is created on the heap then you must use delete.
Deepu Antony wrote: Is q = NULL is correct?
Again, when q points heap-allocated memory you've to delete it. Invalidating the pointer afterward is a good pactice (for instance):
int * q;
q = new int[10];
if (q) delete [] q;
q = NULL;

If you delete memory, which you didn't allocate dynamically, you surly putting yourself in trouble.
Remember simple rule, you only need to delete the memory, which is you allocate to the program!

Hello!
There are LsaEnumerateLogonSessions and LsaGetLogonSessionData functions which can be used to get information about the logon sessions.
But is there a way to enumerate the users that are NOT logged on?
Thanks in advance!

Thinking about what you're asking...
There's local users...
There's users of domain AAAA - which would require lots of traffic...
There's users of domain BBBB - which would require lots of traffic...
There's users of domain CCCC - which would require lots of traffic... oh, and this domain server is in Mongolia. Their head office guy is visiting this week.
And so on.
So, I strongly doubt it!

Such as NetUserEnum()?

Hi,

But if call IsThemeActive() on XP I get always "TRUE", what do I wrong?

See GetModuleFileName()[^]
Usage:
TCHAR szPath[_MAX_PATH];
GetModuleFileName(NULL, szPath, _MAX_PATH);
AfxMessageBox(szPath);
