As you saw, this won't work: the only way I found to set an iconbitmap on a 
window is using the '@/path/to/file' syntax. Why not keep the data for your 
image in the code and generate a temporary file from this data? Then you can use 
the '@...' stuff without having to carry an external file everywhere. Just don't 
forget to delete the file when your application exits. We do that all the time 
and it works quite fine.
