POINT conversion

Hi,

I've been trying to assign the x and y values of POINT structure to a vertex.

Code:

struct vertex
{
	double x, y, z;
	vertex()
	{
		x=0;y=0;z=0;
	}
};

Code:

	POINT MousePt;
	static vertex pointArray[1000];
	static POINT ptArray[1000];

Code:

case WM_LBUTTONDOWN:
		{
			MousePt.x = LOWORD (lParam) ;
			MousePt.y = HIWORD (lParam) ;	
ptArray[numPoints++]=MousePt;


					pointArray[numPoints].x=ptArray[numPoints].x;//??????
					pointArray[numPoints].y=ptArray[numPoints].y;//?????

The last 2 lines do not seem to be assigning values.

I feel like this may have to do with this 'numPoints' character. Where's that rascal defined.

there is nothing wrong with "numpoints".

Code:

int numPoints= 0;

Try making x,y,z to be integers instead of double. I'm totaly guessing, because I'm really tired =(. However, it might work, because you're having implicit casting.

If numPoints is defined inside your windowprocedure then it will be reset to 0 every time it is called (recieves a message), so you will have to define it in some other way like making it static (using the modifier or making it global).
