Hi Mike,
Well using your code I get the expected result at the end of the process
but the interim output that I try to capture shows nothing?
So good news - using your method I get the end result and the user is free
to do other things ; / bad news - I can't show the interim output for
feedback.
If I use the following code I get the opposite effect - user cannot do
anything until the process completes but the interim output updates to the
field.
In both cases the process completes with the final results.
So it has to do with the timing of the send and the reading of the process
(I also tried reading lines and have the same result as reading characters
as shown below)
local nM
on mouseUp
startProcess
end mouseUp
command startProcess
put fld dbPathList into nM
open process nM for update
set the cRunning of this card to true
readloop
end startProcess
command readloop
if the the cRunning of this card then
read from process nM for 10
if it is not empty then
put it & cr after fld mergeOut
put the number of lines of fld mergeOut * 16 into sPlace
set the vscroll of fld mergeOut to sPlace
if it contains "dblink disconnecting" then
set the cRunning of this card to false
close process nM
exit to top
end if
send "readloop" to me in 1 tick
end if
end if
end readloop
