initializing a 100 point array


quote from other post:

Call Graphics.FillPolygon(). You will need a brush rather than a pen and you must put your points into a point array Point[].

The sample code from MSDN is like this:

// Create solid brush.
SolidBrush^ blueBrush = gcnew SolidBrush( Color::Blue );  

// Create points that define polygon.  
Point point1 = Point(50,50);  
Point point2 = Point(100,25);  
Point point3 = Point(200,5);       
Point point4 = Point(250,50);  
Point point5 = Point(300,100);  
Point point6 = Point(350,200);  
Point point7 = Point(250,250);  
array<Point>^ curvePoints = {point1,point2,point3,point4,point5,point6,point7}; 

This is awful! I have to put in a hundred equidistant points!

Draw polygon to screen.

e->Graphics->FillPolygon( blueBrush, curvePoints );

I have tried many things:

array<Point,2>^ aPoints;
//Points tabPoints[10][10];//= new Points[10][10];
Points = gcnew array<Point,2>(10,10);
//init des tableaux 

for (int i = 0;i<10;i++)
{
    for(int j =0;j<10;j++)
    {
    //tabPoints[i][j].pX =i*10;
    //tabPoints[i][j].pY = j * 10;
    // = new Points(i*10,j*10);
    aPoints[i,j]= new Point(i*20,j*20);
    }
}  

None of them work!


Solution

  • A 2-D array isn't necessarily what you want, but you can make your current code work with just one minor change:

    • Get rid of new inside the loop. You want a Point value, not a pointer to one.

    MSDN had that part right already.
