Hi Jim and Bjorn,
You can get this sort of thing to run from Mapbasic, by using 'run
program...'. The only problem is that mapbasic doesn't wait for the DOS
batch file to be executed - if you don't pause your mbx, then your code will
probably try to do something with the output from the batch file before it's
been created.
Clear as mud? Example code below - this creates a DOS batch file to list all
jpegs in str_directory to a file called list.txt:
open file "c:\mapinfo\airphoto\list.bat" for output as #3
print #3,"dir /b "+str_directory+"\*.jpg > c:\mapinfo\airphoto\list.txt"
close file #3
run program "c:\mapinfo\airphoto\list.bat"
note "Click this button to continue" ' this pauses the mbx long enough for
list.bat to run
' (unless you're really fast with the
mouse, or the batch
' file runs really slowly!)
kill "c:\mapinfo\airphoto\list.bat"
- the next stage would be to open list.txt as an ascii file in mapbasic and
do things with its content (oo-er!).
If anyone with more knowledge of DOS and/or mapbasic has a more elegant
solution, then I'd be very interested.
Hope this helps,
