Problem creating new icons

[taxidimu]

I want to create icons from shell32.dll file.
So I extract the selected icons.
In icofx I see copies of these icons in different resolutions. Which one shoul I process?
I try to modify all of them, save as name-res.ico file (ic1-16.ico, ic1-32.ico... icn-32.ico), but get confused on the result.
It seems to me that the new icons are not saved as I want, but in a casual order.
Where is my error?
Same when I build an icon lib.
Thank you.

Hello,

An icon usually contains more images in different sizes and color depth.
Windows will choose the one that it needs from these images, for example for the desktop the 32x32 image is used.
For more info about the icon format: http://icofx.ro/help/icons.html

The order of the images inside the icon if defined by Microsoft, so you cannot change that.

Best regards,
