Director did not give me feedback when it couldn't open a file. I got around this by using the DLLGlue xobject. It seems to need less memory to perform actions and it returns error-specific codes.
Here is the code I use:
on CallProgram WhichFile
if not(ObjectP(factory("DLLGlue"))) then
openxlib "DLLGlue" -- if xobject not available, program halts automatically
end if
-- Send windows call...
set Starter to DLLGlue(mNew,"KRNL386.EXE","WinExec","W","SW")
if not (objectP(Starter)) then -- If object not formed, trip off error later
set CallResult to 1
else
set CallResult to Starter(mCall,WhichFile,2)
Starter(mDispose) -- Tidy, tidy, tidy...
end if
-- Error trapping
if CallResult < 33 then -- If not valid result
if CallResult = 0 or CallResult = 8 then -- Not enough memory?
alert "Installer does not have enough memory. Please close other applications and restart the installer." & return & return & "Installation incomplete."
halt
else -- Blame it on someone else.
alert "KRNL386.EXE will not accept installer WinExec call." & return & return & "Error code:" && CallResult
halt
end if
end if
return CallResult
end CallProgram
It is like fishing with dynamite. Gets the job done very well but has the
potential of being very messy.
