Use EnumChildProc.
EnumChildWindows(hwndParent, EnumChildProc,
0);
BOOL CALLBACK EnumChildProc(HWND hwndChild, LPARAM lParam)
{
}

See MSDN for EnumChildWindows it has a good example

can u tell me how to plot a sin graph in vc++ with y=sin(x).
here where x is from 1 to 100
is the following correct
for(int i=0;i<100;i++)
double y= sin(i);
dc.LineTo(i,y);
using this i am not getting curve
please tell me

To get a curce you have to make the x-axis visible.
Before startting the for loop move the starting drawing point visible.
dc.MoveTo(0, nVerticalCenteroftheWindow);

with addition to my above reply...
we know that sin(90) is 1.
for all the i value less than 90 we will get y < 1 or y < 0.
So you have to map the small values to some high value, that is, the value of 1 will be some 50 or 100. So that the y values should be converted to the new high value and plot the line.

sin(x) gives sine of x where x is in radians. Your plot would be sampling sin(x) about 3 times per cycle so you would be getting a very spikey graph. If you want to plot sin(x) with x in degrees, use
y = sin(pi*x/180);
Alternatively plot y = sin(x) with x going from 0 to 2*pi in say 100 steps - should give you a nice plot.

We can't use the 'y' value as such. It will draw a straight line, because for the x value from 0 - 90 the y value will be from 0 to 1. That is you will draw lines with varing x but the y vakue will be 0 untill 90. you can get 1, while x = 90.
So to plot, we have to map the y value to some larger value...

You're right - guess we have given enough hints for the homework

CDialog* pTest=(CMyParent*)GetParent();
pTest->EndDialog(0);
will close the parent dialog from the child dialog
Somethings seem HARD to do, until we know how to do them.

No the parent dialog closes anyways.

before trying to do this, i'd lie to know why you would want such a thing ?
a modal child dialog cannot be orphaned...
