Change Icons dynamically

My application has a copy of another application.exe (my own creation) in the resources. With a button click, my application will create a new copy of the .exe in my.resources.

Code:

---

IO.File.WriteAllBytes(path, My.Resources.My.exe)

---

I am also obtaining an .ico from an image:

Code:

---

                Dim Ico As Icon
                Dim bmp As Bitmap = Image.FromFile(DisabledDir & itm.Text & "\icon.png")
                Ico = Icon.FromHandle(bmp.GetHicon)

---

The question is: Is it possible to change the icon of the .exe file either before or after creating the new file.

Thank you for your responses.

That depends on what you mean by "the icon of the EXE". If you have compiled an icon into that executable then no, you can't change that, because it's compiled. If you mean that icon used for a shortcut to that executable then sure, because that shortcut is something that you are creating from scratch.
