How to draw a graphical object independently?

[sunkingac]

Hai all,

I am doing a project involving graphical drawings.

In my project, I add every drawn elements in a pointer list.
And, while drawing a new element ie on every mouse move, i redraw all the elements in the pointer list and draw the current elements with the new coordinates.

This slows down my application.
I tried Double buffering and XOR techniques but in vain.

Is there any other way to draw an element without disturbing other drawn elements?

Please help me.

With Thanks,
Arun Chakaravarthy

Do you by any chance handle WM_ERASEBKGND. May be you want to trap that and do nothing.

When windows needs to paint, it may send a WM_ERASEBKGND and if you don't handle this, the default window proc will erase the whole bkgnd with the bkgnd color. This could result in a flicker.
