Hey guys,
I'm writing a function that waits for a short time for a file to appear
before timing out. The basic idea is
function WaitForFile(somefile, timeout)
starttime = now()
bFileExists = FileExists(somefile)
loop while not bFileExists and (now - startime) < timeout
Sleep(1000)
bFileExists = FileExists(somefile)
end loop
return bFileExists
end function
Since CF doesn't have a Sleep function, I'm stuck with workarounds. I can
do it either by accessing the java.lang.Thread classes (much thanks to
Christian's Blog at http://www.markme.com/cantrell/archives/002801.cfm), or
by writing a COM object that does effectively the same thing. The question
is: does blocking the currently executing CF thread using the java Sleep()
method differ from blocking it using a synchronous COM method ? In other
words, does anyone know of any internal CF quirks that would make it less
safe to use the java method vs the COM method? Future-proofing is not a
concern at this point, though I'd wager support for the java base classes
isn't being removed from CF any time soon ;)
<CFSCRIPT>
thrd = CreateObject("java", "java.lang.Thread");
thrd.Sleep(javaCast("long", 10000));
</CFSCRIPT>
TIA,
RC Collins
