Erasing the line drawn using CDC

[lukevprem]

Hi,

I draw a line using CDC's LineTo method. After sometime, I want to erase the line. I dont know how to do it. Is there any method in CDC by which we can erase a line or drawing segment?

Thanks,
Luke.

Draw the line again with the background color.

you can do it to draw a line using XOR brush

Thank you both. It was helpful. I am doing it with the background color.

What do you do if the background is set to transparent?

This is not going to work if you, for example, drew a second line across - you will erase an intersection point.
The only proper way is to redraw everything except for the line you want to erase.
