Hi,
As you have not posted even a small part of the code. It is really hard for me or anyone to understand how exactly you want to draw a rectangle. But as you said its a pictureBox so i assume you are working close to Windows forms.So I have written this code which can help you to manipulate Images. I hope this helps, if not post your code so it is possible to see how you are approaching to solve this problem. :)
System::Drawing::Bitmap^ BM;
System::Drawing::Color C;
BM = (System::Drawing::Bitmap^) Image::FromFile("pic.jpg");
int i,j;
for(j=20;j<=25;j++)
{
for(i = 30;i<=100;i++)
{
BM->SetPixel(i,j,C.White);
}
}
BM->Save("pic2.jpg");
