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

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...

Dear all,
In my project I woyld like to send data step by step, so now I want to put timer in this source to delay for each step, for example:
send data 1
delay 2 seconds thend
send data 2
delay 2seconds
...
Anyone who have experence with timer in VC+ please help me solve this problem. Many thak for your help. As below is my source code:
void DlgComputing::OnButtonSendtorobot() <br />
{<br />
int rowData, rowOutput;<br />
int tmpi[3];<br />
<br />
rowData = m_grid2.GetRow();<br />
<br />
for (int i=1; i<= rowData; i++)<br />
{<br />
for (int j=5;j < 8; j++)<br />
{<br />
m_grid2.SetRow(i);<br />
m_grid2.SetCol(j);<br />
CString tmp = m_grid2.GetText(); <br />
tmpi[j-5] = atoi(tmp);<br />
}<br />
SendtoKuka (tmpi[0],tmpi[1],tmpi[2],m_iA,m_iB,m_iC);<br />
}<br />
SendtoKuka(0, 0, 0, 0, 0, 0);

WinAPI Sleep(...) could give u help on delaying 2 seconds.
