I'm writing a C++ program which minimizes a batch file to the system tray. I want to add a piece of code which will change the system tray icon if the batch file updates (that is, another line is printed onto the cmd.exe window)
Any ideas on how I could do this?
Thanks

Why not get your program to execute the batch file itself (using CreateProcess). Then it can capture the batch files output directly[^] rather than having to go through some intermediary. Oh, and your program could write the batch file output to a rich edit box or something?

how do we specify two flags for a create file attribute dwFlagsAndAttributes??
|
|
|
|
|
I'm not sure I got your question but if you want to combine two flags into one variable (and that's a general case), you have to use the | operator (OR):
int Flag = FLAG1 | FLAG2;
Does that answer your question ?
|
|
|
|
|
Yeah, but i was really confused with the others. thank you.
|
|
|
|

Use a bit-wise OR to combine them - so, to create a read-only, hidden, system file, you'd specify FILE_ATTRIBUTE_HIDDEN|FILE_ATTRIBUTE_SYSTEM|FILE_ATTRIBUTE_READONLY

BITWISE operator can help!

Hi all,
I have made a Dialog based application in vc 2008. In my application i am opening second dialog box using DoModal() on a button click event of first dialog box. In second dialog box i am starting a worker thread in my OnInitDialog() function.My problem is while my second dialog box is still doing some work, first dialog box can be closed in the back that is it is active.
Please help me in this
Thanks in advance

Are you telling that you are able to close your first dialog while the second one is still active, or are you asking how to get this done?
With DoModal(), the runtime will spawn a Modal dialog, which will need to be dismissed to go back to the parent (the window that spawned it). You must use CDialog::Create[^] if you need a modeless dialog.

No i am telling that i am able to close it and i don't want to close it. I am not getting why a modal dialog is behaving like that
|
|
|
|
|
That cannot happen. Have you checked the return value of the dialog that you spawned with DoModal()? Also, when exactly is your modal dialog returning?

Its returning when i close the dialog box but parent dialog box can be closed and i get the ret_value after child dialog box is closed.
Save obj;
int ret_val = obj.DoModal();

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()?

are you talking about single computer or domain?
