How to change icon in .exe (App Wxwidgets with C++)

[wnap]

I build app with Code::Block, C++ and Wxwidgets. I changed icon for frame successfully, but icon at file .EXE is still there.

You'll need to use a resource file (*.rc) on Windows. Read the spec on MSDN how this works, you can inspect the sources of C::B for an example. Make sure you name your icon in a way that it appears at first in the resource list.

As an example, the project I work on uses an rc file for this:
https://raw.githubusercontent.com/raynebc/editor-on-fire/master/src/eof.rc
https://raw.githubusercontent.com/raynebc/editor-on-fire/master/src/eof.ico

The RC file is a simple text file with this content:

Code

allegro_icon ICON myfilename.ico

That's with a carriage return and line feed at the end of the line (Windows style encoding), in case this makes a difference.  The ICO file itself seems to be a pretty standard Windows icon image.  When I open that in GIMP, it appears to have 5 layers, each with the graphic in a different size.
