Which accuracy do you need to have ? If you look for an accuracy under 15 msec (approximately), then you can forget about it. Windows is not a real-time operating system and thus, you cannot have precision under 10 or 15 msec (depends of which version of windows you are using). If you don't need a so much precision but still want to have something better than Sleep, you can have a look at GetTickCount[^]. You'll be able to do something with it.

Use Synchronisation techniques instead of Sleep..
several synchronisation techniques are available here
CriticalSecction,
mutex,
semaphors, etc.
Use appropriate for efficiency and performance.

i face a problem
problem is that then i make dialog box in mfc and make its class and also make a menu then i add this menu to the the dailog box . menu contain two commands one for addition and one for updation.
i make second dialog box in mfc then i add some edit controls on it and make a class of this dailog box.
so when i click on addtion command on menu in first dialog box it display second dialog box
and when i click on updation command in menu then it will again display second dialog box but now i want that some edit controls are disabled that is they can not take value
how can i do this
plz help me whoever know this
thanks
ya u give solution but that is not solve my problem
i want to disable it from menu which is on first dailog box and i want to disable edit control on second dailog box so enablewindow demand of object and i declare object of that edit in second dialog box and in first it will not take that one

for disable and enable controls use EnableWindow

We have already provided a solution for your problem. What problem are you still facing

Create the pointer of the Secoend dialog box into first one and access the elements/Objects through that pointer.
Hope i understood your problem.

i made a class of the the first dailog box which contain menu as CAfterone
and made a class of second dialog box which contain edit boxes as CAgaindialog now i declare
CAgaindialog *pop; in the header file of the CAfterone
ass i declare it in CAfterone :: public CDialog (public mode)
////////////can i declare it any where or in the class
CAfterone :: public CDialog (public mode)////////////
then i use to call second dailog box from menu as
void CPasswordDlg::OnDel()
{
d.DoModal();
pop->GetDlgItem(IDC_EDIT)->EnableWindow(FALSE);
}
but it will not do job for me

Try to make the Variable as extern , initialise it properly before invoking the enablewindow api.

as i make variable of edit control of the type CEdit how could i make it extern
d.DoModal();
pop->GetDlgItem(m_nemp)->EnableWindow(FALSE);
i take m_nemp as CEdit type and call it but it will give error that undefind in class one

I mean make extern variable of the second dialog box.
access it after initialisation.

Hi gurus,
what is the difference between following statements
int *p[10];
int (*p)[10];
what is the memory structure for both?
How to access the elements?
Thanks in advance..

int *p[10];
it is a two dimensional array and its elements can be accessed as
p[0][0],p[0][1].....

i think int *p[10] is array of 10 pointers.. am i right?
where we have to allocate the memory for each..

See for int *p[10];
<br />
int *p[2];<br />
memset(&p,0,sizeof(int[2]));<br />
<br />
int b=10;<br />
p[0]=&b;<br />
int c;<br />
c=20;<br />
p[1]=&c;<br />
<br />
int A;<br />
A=*p[0];<br />
A=*p[1];<br />

int *p[10]
is a array of 10 pointers.
and i think second one is pointer to an array of 10 integers.
or you may declare it as int **p
assign memory to *p of 10 blocks so it will be an array
and then **p will be the pointer to array of 10 integers.

Since in operator precedence the "[]" operator has a priority above the "*" operator, the expression "int *p[10]" denotes an array of ten pointers, each pointing to an integer. In "int (*p)[10]" the order of interpretation was changed, and here we have a pointer to an array of ten integers.
In the first case, the size of p is 40 bytes (in our compiler), in the second case, the size is 4 bytes.
In the first case, you can assign new value for each array element like this:
p[2] = &z;
p[7] = new int;
Expression like *p[2] here can be used to change the value of z:
*p[2] = 100;
In the second case, you first have to allocate an array and assign its address to the pointer:
p = (int (*)[10]) new int [10];
Now you can access elements from this array:
(*p)[3] = 100;
(*p)[5] = 200;
Then you can delete the array:
delete [] p;

Viorel wrote: p = (int (*)[10]) new int [10];
Is it necessary to typecast the allocated memory ??
As per my knowledge the new operator returns the appropriate pointer.
or Should we allocate memory as
p = new int [5][10];

I think, with older compilers an assignment like "int (*p)[10] = new int [10]" would work, but today, in VS 2003 or GCC, it is not acceptable. Compiler complains: "cannot convert from 'int *' to 'int (*)[10]'". I suppose this is made to follow standards.
Regarding the second question, yes, you can make the assignment "int (*p)[10] = new int [5][10]" if you are going to interpret p as a pointer to bi-dimensional array. You can refer the elements like p[2][7].
