Change app icon in Visual Studio 2005?

Question

I'd like to use a different icon for the demo version of my game, and I'm building the demo with a different build config than I do for the full verison, using a preprocessor define to lockout some content, use different graphics, etc. Is there a way that I can make Visual Studio use a different icon for the app Icon in the demo config but continue to use the regular icon for the full version's config?

According to this page you may use preprocessor directives in your *.rc file. You should write something like this

#ifdef _DEMO_VERSION_
IDR_MAINFRAME ICON "demo.ico"
#else
IDR_MAINFRAME ICON "full.ico"
#endif

You can indeed use preprocessor directives in your rc file. I'd say this is the way to do it. +1 – Furey

This is the best solution. I didn't realize that it was working at first because explorer cached my icon, so I also discovered that you can set the conditions via that icon properties in the resource viewer. – Chapell

What I would do is setup a pre-build event (Project properties -> Configuration Properties -> Build Events -> Pre-Build Event). The pre-build event is a command line. I would use this to copy the appropriate icon file to the build icon.

For example, let's say your build icon is 'app.ico'. I would make my fullicon 'app_full.ico' and my demo icon 'app_demo.ico'. Then I would set my pre-build events as follows:

Full mode pre-build event:

del app.ico | copy app_full.ico app.ico

Demo mode pre-build event:

del app.ico | copy app_demo.ico app.ico

I hope that helps!

This will get you halfway there: http://www.codeproject.com/KB/dotnet/embedmultipleiconsdotnet.aspx

Then you need to find the Win32 call which will set the displayed icon from the list of embedded icons.

I don't know a way in visual studio, because the application settings are bound to the hole project. But a simple way is to use a PreBuild event and copy the app.demo.ico to app.ico or the app.release.ico to app.ico demanding on the value of the key $(ConfigurationName) and refer to the app.ico in your project directory.
