(drawEllipse) draw an Ellipse at mouse position [UNSOLVED]

[vb_elmar]

(I'm using Windows10 @64bit)

Hello,

I'm using the apiguide sample: GetWindowDC

The sample (see attachement) will draw an Ellipse at the mouse position on the active window.

I'm watching a youtube video (using Firefox) and it works fine. But when compiling the *.vbp project
to an *.exe the Ellipse at the mouse position will disappear after an half second.

How can I prevent the ellipse from disappear?

This is because the window is repainted.
The same happens on every window you resize. Or hide and make visible again.

>>This is because the window is repainted
but when the project is NOT compiled the Ellipse at the mouse position will stay.

How can I prevent the ellipse from disappear when the project is compiled?

I have tested it also from the IDE and the circles disappeared when a window was repainted.
I tested it on a browser, on outlook, every form repaint makes the circles disappear, which is logical because the owner of the windows does not know anything about the drawn circles.
I'm using Win7 (32bit)

as the (attached) picture shows, dozens of ellipses are remaining, when the project is NOT compiled (I'm using Firefox, and Windows10 @64bit).

-What must I do to prevent the ellipses from disappearing when the project is compiled?

Before I step out of this discussion, what is your goal?

[vb_elmar]

I want to make a project drawing Ellipses on youtube live streams.

My problem is: when the project is compiled the ellipses at the mouse position will NOT stay. Unfortunately
the ellipses disappear within a half second (when the project is running in the VB-IDE all the ellipses remain).

Now I want to know what I have to do to prevent the ellipses from disappearing at the mouse position
when the project is compiled.

Then you have to store the coordinates of all mouse clicks/movements and draw all circles up until the current moment.

[vb_elmar]

No, I don't have to store the coordinates of all mouse clicks/movements. There must be another (simpler) solution
to be able to draw ellipses on youtube live stream windows. -The youtube shibuya website e.g. is such a live stream window.

My project is working fine so far. But how can I prevent the ellipses from disappearing at the mouse position
when the project is compiled??
