Good morning!  (Well, in my dusty little corner of the planet, anyway ...)

Have you tried free_console()?

Each window actually has two icons, a "large" icon, and a "small" icon.  At
present,
win32lib.ew only sets one of these, which is why you see the standard
IDI_APPLICATION icon in ALT
+ TAB.  To fix this, be sure to use setIcon() first.  Then:

object xVOID

    xVOID = sendMessage(yourWindow, 127, 0, 0)     -- 127 = WM_GETICON
    xVOID = sendMessage(yourWindow, WM_SETICON, 1, xVOID)

That will synchronize them.


>* Is it possible to embed an icon into an exe?

bindw has a flag -icon, which embeds the icon onto the bound executable.  More
information about
this is in the standard documentation file, bind.htm.

When you go to the .exw file using the prompt, you probably *cd* there, which
makes your exw
file's directory the current directory.  However, when dropping the file onto
the exw shortcut,
more than likely the current directory is then c:\windows.  Thus, if setBitmap()
for the button
uses a relative filename, the file might not be found.

Using the command_line() function, and looking at the path on the running file's
name (the second
element of the sequence returned by command_line()), you can figure out the
running file's home
directory and then use chdir() to make it the current directory.

That happens a lot in win32lib.ew.  Derek, why is this a function, and what is
the return value?
