[DUG] Change the icon of a Delphi EXE file

[Jeremy Coulter]

It might be decreasing the colour depth when its added to the exe. If it is,
then that would account for the loss of bytes.

I've found a resource changer library at
http://www.wilsonc.demon.co.uk/delphi_5.htm
There's a TResourceModule component, which can open an EXE file. The it
lists out all the resources: cursors, icons etc.

And here's where the weird thing starts: let's say I use a 766 byte icon for
a Delphi application, I compile it and place it at C:\demo.exe. Then I use
the TResourceModule component to access the icon. The icon will have
744 bytes! If I extract these 744 bytes to a separate file, it will not be a
valid ICO file. However, if I return them back into the application, then
the application will use that as a valid icon.

On the other hand, if I try to use the original 766 byte icon, the
application will become icon-less.

I have no idea why the icon loses 22 bytes after it is compiled into an exe
file. Maybe the header is stripped?

Anyway, I'm trying various hacks to get over this, because right now I
cannot use regular ICO files, none of them work.
The TResourceModule component seems to work nicely though ;)
