This really belongs on the Urgent board as others have mentioned.

I have to ask why it's such a problem to include a dll with an exe?

If you plan on statically linking the code that's in the DLL with your application then you need
to rebuild the DLL as a static link library.

Good luck!

Use EnumChildProc.

EnumChildWindows(hwndParent, EnumChildProc, 
                0); 
BOOL CALLBACK EnumChildProc(HWND hwndChild, LPARAM lParam) 
{ 
//here hwndChild is child window handle, and this function will be called for each child of this parent
}

drawing a sin graph in vc++

14-Mar-07 18:39

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...
