1. Re: edita 0.1.6/WM_COPYDATA experts?
Hi there Pete,
First off, Microsoft recommends treating the pointer passed in the
COPYDATA struct to be 'read only' by the called process. Unfortunately
i dont know the reason behind them including this 'fact' in the
documentation so i cant say when it will work otherwise.
Second, the source of the filename problem might be because Eu's
'current_dir()' function does not always work as expected.
I've uploaded a fix for this quite a while back i think it was
called 'GetCurrentDir' but i cant find it now so here's the
file:
--GetStartupDir.ew--------------------------------------
sequence CommandLine,SUDir
CommandLine=command_line()
SUDir=""
if length(CommandLine)>1 then
CommandLine=CommandLine[2]
for k=length(CommandLine) to 1 by -1 do
if CommandLine[k]='\\' then
SUDir=CommandLine[1..k]
exit
end if
end for
end if
global function GetStartupDirectory()
return SUDir
end function
----------------------------------------------
The idea is to:
1. include the file early in the program.
2. call 'GetStartupDirectory()' as soon as the program opens
in place of where you would want to call 'current_dir()'.
I think this will help the XP problem, but even if it doesnt
it's a good idea to use GetStartupDirectory() anyway because
you never know if your user might open the exe with a mouse
drop action.
Take care,
Al
And, good luck with your Euphoria programming!
