Re: Strange problem with tsNet external on Windows

[Graham Samuel via use-livecode]

I finally answered my own question - it was simple and I was nearly right in my 
first guess. I forgot to include the ‘Externals’ folder in the files and 
folders encapsulated by the PC installer maker. I suppose I live too much in 
the Mac world. The live program looks for an ‘Externals’ folder in its 
immediate vicinity and if it doesn’t find one, or the contents are wrong, it 
very sensible reports an error. It would be better if the error was “can’t find 
Externals folder” rather than “can’t find tsNet”, but that’s a weak excuse on 
my part.

There you go - deployment stumbling block number 42, I suppose.

RE: Strange problem with tsNet external on Windows

Graham,

Also check tsNet, it's way down at the bottom of the inclusions pane. Or you 
can disable tsNet and use only libURL.

Here are a couple of handlers to find out if is tsNet is enabled. Below that is 
how to explicitly enable/disable tsNet.


function GetNetworkType
   local tLibUrlDriver
   
   try
  put the behavior of stack"revLibUrl" into tLibUrlDriver
   end try
   if tLibUrlDriver is empty then
  return "Sockets"
   else
  return "tsNet"
   end if
   
end GetNetworkType

command NetworkType
   if GetNetworkType() = "Sockets" then
  answer"tsNet is disabled"
   else
  answer "tsNet in use"&"Version==>"& tsNetVersion()
   end if
end NetworkType


To unload:

dispatch "revUnloadLibrary" to stack "tsNetLibUrl"

To load again:

dispatch "revLoadLibrary" to stack "tsNetLibUrl"

Subject: Strange problem with tsNet external on Windows

I have a LiveCode standalone running as PC app (a .exe file, plus some other 
files which are needed when it runs). If I simply run the original standalone 
on Windows 7 (OK, running under Parallels on a Mac), it all just works. If I 
create an installer for the program and its dependent files using Inno Setup, 
the whole thing appears to run smoothly, but when I run the installed version 
of the app (which is exactly the same size as the original standalone, as 
expected), I get an error from the LC engine “Initialization Error: Failed to 
load external: tsNet”. I suppose I have somehow failed to include tsNet, but it 
was specifically included in the standalone (as “internet”) and anyway the 
original standalone works.

Should I somehow be giving my installed app a path to the LC externals? I’m 
confused.
