It'd be crude, but you could experiment with LineTo() (which can draw one-pixel dots) and related functions.

If you are looking for a graph that need to be drawn by yourself, then go for a custom control. It can simply be developed from CStatic.

One way to do it without many difficulties is to walk around.

You can get without difficulties the mouse messages/events in the dialog box. And you have a parameter CPoint point that gives you where the click was made or the pointer is.

then...

Just take the coordinates of the bounding square of your picture and ask if you are inside of it. I mean:

CRect rectPict;
rectPict.top = YourPicture.top;
rectPict.bottom = YourPicture.bottom;
rectPict.left = YourPicture.left;
rectPict.right = YourPicture.right;

if (rectPict.PtInRect (point))
{
//Do whatever you want while over the picture
}
else
{
//Do other things while in the rest of dialog
}

Hope it helps

Greetings.

Which contrasts with your initial "when I let mouse over the PictureBox only" comment. Make up your mind before asking for help. Roll eyes | :rolleyes:

Derive a class from the picture box using the ClassWizard. Then you can manage the messages.

Dr. Stroustrup had nothing to do with C. Furthermore, he was not "one of the founders" of the language; he was the designer and original implementor of it.

From where do you start?

Do you know programming but need to learn syntax and idioms of C++?
What language did you do before?
Are you just starting with programming as a whole?

I used
Nicolai M. Josuttis,"Object oriented Programming in C++", Addison-Wesley
Nicolai M. Josuttis,"The C++ standard library", Addison-Wesley
Richard M. Jones, "Introduction to MFC-programming with Visual C++", Prentice Hall

These are when you know all the basics, but before you developed a personal style:
Scott Myers, "Effective C++", Addison-Wesley
Scott Myers, "More Effective C++", Addison-Wesley
Scott Myers, "Effective STL, Addison-Wesley
