How can I change the task bar icon of a published game? I've tried numerous methods described in various threads on this forum. All methods have something lacking. The one I have been using is changing the acknex.exe file's icon through a resource editor (ResEdit specifically) and then publishing with the new acknex.exe file. This works perfectly except for one problem: The icon that shows in the Windows task bar comes from acknex.dll, not acknex.exe. Using the same resource-editing method with acknex.dll works, but only with the -nc flag and only when launching directly from WED. If I publish the game, even adding the -nc flag to a shortcut that points to the published exe does not work. The engine returns an error saying that the implementation "has been corrupted" (even though -nc should prevent the engine from looking for corruption). So, how can the icon in the Windows task bar be changed in addition to the exe icon?

Interesting task!
(i don't think conitec will help you with this ) so try this

you can do this using the Windows API SendMessage function.
you'll need to use the engine variable hWndMain
you'll need to read about how to use LoadIcon

here is a Delphi Example from the SDK Samples. This example is loading the new icon from a resource file.

// Uses icon from resource file (.rc) for the A7 Engine window.
SendMessage(ev.hWndMain, WM_SETICON, 1, LoadIcon(MainInstance, 'PROGICON'));

Mercuryus, you are my hero. Your demo app was extremely helpful. I now call the function to change the icon in the first line in my main function, and the icon changes immediately. Unfortunately, I still have the problem of the A6 icon appearing while C-script is being compiled and the splash screen is showing, before the main function actually begins executing. Any ideas for how I could change the acknex.dll icon even before the C-Script has finished compiling? Again, I can't thank you enough for this concise and highly effective demo app.

If you're using an external DLL, you can put the icon switching message call in the DllMain call. It's executed before compiling.

Thanx, I will try this...

Mercuryus, I don't want to ask too much, since your demo and dll have already helped so much, but if you do decide to give the dllmain fix jcl suggested a try, I'd love to get a copy. Otherwise, I'll see if I can create some sort of "proxy dll" that calls your original dll from dllmain. Many thanks again.

download the zip again.
now the icon is changed automatically (DLLMAIN) to ICON.ico if it exists.
Unfortunately the blue A7-Icon is still visible for a moment.
