Re: MI-L Stop map redraw (integrated mapping)

[Matt Bolton]

Ash,

I'm using a MI window integrated on the VB form (in a pic box). 

I gather from your post that you've tried set map redraw off, and it 
works sometimes, but not others  - is that right?

Not sure about the echo options - does it work in VB as well as VBA (a 
help search only bought up a reference in Access Help).
I've tried it in my code, but it doesn't work - perhaps because the 
reference to MI is as an object:

   Set mobjMI = CreateObject("Mapinfo.Application")
   MI_Do "Set Application Window " & mlPicHwnd
   mobjMI.Echo False
How do you use it?

Thanks,

Matt

is your map window integrated into a form or is a form controlling the MI

if it's on a form, you could just set the host application echo properties
to false or make the form not visible for a bit.
i know it's annoying though, i think in my apps when there's a lot of
processing to happen on the map, i ended up just making the form invisible.
a decent process, zoom to with long zoom and redraw would usually take about
15 seconds, but i got it down to like 3 by not displaying stuff as it
happened.
as to the map redraw option, i've found it to be hit and miss, so i've
pretty much gotten rid of the command and just use the application.echo
feature on the host app.
dang, huh?

Hi all,

I'm doing some complex MI map & data manipulation via integrated mapping 
using VB  (I know I could do with MapBasic, but I'm more familiar with 
VB).   I want to be able to do all the processing without the map window 
redrawing after each step, but have tried the following without success:

objMI.Do "Set Event Processing Off"
         and
objMI.Do "Set Map Redraw Off"
Neither seems to have any effect.  Can anyone suggest what I need to do 
to get either of these to work?

Thanks,

Matt
