You don't know if you can refresh your controls. If some idle process is consuming all the CPU cycles, it won't affect your process. If a process with a higher priority consumes all the CPU, your program won't even run..
If it's your application which consumes all the CPU, I suggest you find out which loop is running like crazy and fix it. Users generally don't like it when a application takes all the CPU..

I am using VC++ of Visual Studio .NET.
The problem here is When I create two tool bars and add them to a rebar as follows the two toolbars will be at each side. I want them both to be Left Aligned one after the other.
Note: the very same code works as i want in VC++ 6 of Visual Studio 6.
if (!m_wndToolBar.CreateEx(this, TBSTYLE_FLAT, WS_CHILD | WS_VISIBLE | CBRS_TOP
| CBRS_TOOLTIPS | CBRS_FLYBY | CBRS_SIZE_DYNAMIC) ||
!m_wndToolBar.LoadToolBar(IDR_MAINFRAME))
{
TRACE0("Failed to create toolbar\n");
return -1;
}
if (!m_wndClientToolBar.CreateEx(this, TBSTYLE_FLAT, WS_CHILD | WS_VISIBLE | CBRS_TOP
| CBRS_TOOLTIPS | CBRS_FLYBY | CBRS_SIZE_DYNAMIC) ||
!m_wndClientToolBar.LoadToolBar(IDR_CLIENTTOOLBAR))
{
TRACE0("Failed to create toolbar\n");
return -1;
}
if (!m_wndReBar.Create(this) ||
!m_wndReBar.AddBar(&m_wndToolBar) ||
!m_wndReBar.AddBar(&m_wndClientToolBar))
{
TRACE0("Failed to create rebar\n");
return -1;
}
if (!m_wndStatusBar.Create(this) ||
!m_wndStatusBar.SetIndicators(indicators,
sizeof(indicators)/sizeof(UINT)))
{
TRACE0("Failed to create status bar\n");
return -1;
}
Thanks.

You tried to access some memory location which is denied for your Program.. Where do u get this Violation i.e. calling which api or function... if function is your own... show the snippet.

But why that memeory is denied for I m or my pgm is using the memory which is being assigned to use for it...
I was trying to assign one address to void pointer.
Chalo now bye

Well, you can't arbitrarily assign an address to a pointer and expect it to work. Did you do something like
void *p = (void *)0x003261b6; ?
Let me try explaining why it doesn't work in the simplest way possible.
Every program has something called a virtual address space allocated to it, to prevent one program from trampling over another program's memory. Now whenever you try to access memory, the OS and the CPU conspire to translate the virtual address to the actual physical address. To do this, the OS has to maintain a mapping between virtual and physical addresses and has to know which virtual addresses have been allocated by the program and which have not.
In your case, you're trying to access an address which has not been allocated to the program and that's why you're getting the access violation error. You must consider yourself lucky it crashed straightaway. Imagine the consequences if it worked on your PC, because by some coincidence that memory *was* allocated somewhere else (by the OS or by you), and it crashed right in front a 100 people when you are giving a demo.
Bottom line : Never do the above unless you are dead sure that address has been allocated.

no I was not doing that...
well, I was doing following thing,
//asign the address to a void PTR
Base = &(FileVersionInfo->dwProductVersionMS);
Before above code I m writing this,
dwVerInfoSize = GetFileVersionInfoSize( szAppName, &dwVerHnd );
cout << dwVerInfoSize << "\n";
if I comment cout stmt my pgm gives me that error.If I uncomment it it works fine.why is that so...I was really confused...
anyways bye. In betwn are U same Senthil who helped me in my final year engineering for XML parser.
thanks

It's possible that FileVersionInfo instance went out of scope and consequently got destroyed, but you're still having a pointer to it's swProductVersionMS member. Could you paste the whole function where the problem is happening?

In Yahoo Programming chat rooms? Then yes.

There is another issue if the code is crashing somewhere after the assign. Do you actually access the pointer at some point in time or does it crash when you leave the fn.

Small Logic:-
void main()
{
int i,j;
bool bPrime=true;
cout<<"enter the number ( greater and equal to 2 ) : ";
cin>>i;
for(j=2;j<i-1;j++)
{
if(i%j==0)
{
bPrime=false;
break;
}
}
if(bPrime)
cout<<endl<<i<<" Number is prime";
else
cout<<endl<<i<<" Number isnot prime";
}

A prime number, by definition, is divisible only by 1 and itself. Your program finds an integer that, multiplied by itself, is equal to the user's number.

First you have to know what a prime number is. The rest is just symantics here.
In other words, write some code and post it with your question. The odds are that while you are writing it, you'll get your see answer.

I want to have an array of objects for an object horse.
horse oHorse[3];
horse Jabo;
horse DarbyDan;
horse BigRed;
How would I set a horse named Jabo using the array?
I've tried oHorse[0] Jabo; but I get that Jabo is an undeclared identifier. I'm a newb so please explain any concepts if you feel they need explained.
Thanks

what do you mean by "name" ? does the horse object have a name member variable ?

No, Jabo, BigRed would be the name of the horse object itself. horse BigRed; is a horse named BigRed. From there I could say BigRed.ShowStatistics();
Thanks

Instead of set I meant declare, sorry.

i still don't know exactly what it is you're trying to do... but, it sounds like you want an array where eac element in the array has a unique variable name. ... ?
if that's true, then you can do it in a couple of ways. here is the basic code:
horse horsearray[3];
horsearray[1].SomeMemberFunction(...whatever...);
if you want to give them names, in a way, you can do something like this:
enum {Jabo = 0, DarbyDan = 1, BigRed = 2};
horse horsearray[3];
horsearray[DarbyDan].SomeMemberFunction(...whatever...);
or, if you want to make your code confusing:
horse horsearray[3];
horse *Jabo = &horsearray[0];
horse *DarbyDan = &horsearray[1];
horse *BigRed = &horsearray[2];
DarbyDan->SomeMemberFunction(...whatever...);
