1. Win32 Constants and IShellLink
Greetings Euphorians!
I have been "lurking" about this mailing list for awhile, reading the
previous months' logs and current mail before blurting out something
stupid. Well, now it's time!
I am trying to write a simple software installation program using
Euphoria for Win32 which will allow the user to select his destination
folder, optionally place shortcuts in his Start Menu and on the Desktop,
read from and write to the registry, and perhaps even create an uninstall
routine. At first I was just going to model my program after Euphoria's
Install.ex, but I need to give the user the ability to choose his
destination folder and still create shortcuts, and I need to be able to set
up file associations in the registry.
I quickly decided that I was going to need EXW and Win32lib.ew for dll
access, message boxes, etc. As I proceeded, however, I became increasingly
convinced that my system ("start...") and system ("copy...") calls were
just not going to pan out. Not only is the up-and-down black DOS box
annoying and unprofessional looking, on my computer (Pentium 233MHz,
Windows95b, 48MB RAM), the system() procedure hangs up half of the time
when running a EXW program using Win32lib.ew. Sometimes it carries out the
command asked for and then fails to return to my program until I manually
click anywhere in the black box. Calls like system ("start
c:\\windows\\temp\\help.htm", 2) hang before starting the web browser and
actually require CTRL-ALT-DEL to exit. Starting files this way using other
applications seem to work most of the time -- most of the time -- if they
do not involve DDE (I think).
So... I decided I'd have to wrap Win32 CopyFile, MoveFile, DeleteFile
and ShellExecute as well as some of the Registry functions. No problem...
Oh, wait, problem. All I have to go by, besides David Cuny's Win32lib.ew
(my inspiration!) is the Win32 Programmer's Reference.hlp from Borland's
FTP site. (I went back there yesterday and found a "new" version 23.6MB
vs my old one of 10.7MB). One would think that in all that, the values of
constants such as MOVE_COPY_ALLOWED would be given, but Noooo... The other
problem I seem to be up against involves Shortcuts. How does one access
the IShellLink interface and its associated methods from Euphoria? Can it
even be done?
I spent over three hours going round-about at Megasoft looking for
answers to these questions without success. If anyone knows where to find
the global constants for Win32 and/or how to access IShellLink, please let
me know.
Thanks in advance, and sorry to be so windy...

Hi,
I have two solutions to this problem:
One: Buy an API book. I really like Dan Appleman's "Visual Basic Programmers
Guide to the Win32 API" and have found that it is a great resource. It has a
lot of the constants in there for you.
Two: Email me privately the constant names that you need and I'll see what I
can find for you. It might take me a couple of days to get back to you.
Email is blackdog at cdc.net
Thanks,

P.S. My EuC Homepage (I know a really dead site) is gone. My ISP had a HD
failure and lost all the frontpage server websites. I had planned to rewrite
it anyway and upload a better version of it. It will be out-of-service for a
while.

From the ignorant:
What is a "wrapper"?
What is a "blit" (we won't mention that I use them, whatever they are)?
And, could you mention exactly where this is, please?

didn't see a 10 or 24 meg ver anywhere.
