Re: MI MapInfo Compatibility Problems?

2000-06-01 Thread Kazuhiko Yamashita
Hi Adrian,


 so I can't see why MI cannot at least allow some backward compatibility.

I really feel the same. In my office, there are MI4.1Japanese, MI4.5J, MI5.0J
and MI5.5English.
MI5.5E can read every Workspace created by both same and lower Japanese
versions of MI ...though it cannot show Japanese/Chinese characters properly.
MI4.x cannot read Workspaces created/edited by MI5.x(English or Japanese).
We usually do not use newer or complicated features of MapInfo but
collaboration among different versions of MI is not impossible but VERY
FRUSTRATING.
I think there are some tools  released by third parties, to edit "wor files",
such as Workspace Control by an Aussie company. I do not know it can show
difference in different versions.

 I do not see any good reason why in its 'save table as ', and 'save
 workspace as' options they cannot allow users to choose to save files
 as older 4.*  types not simply as version 2. If Adobe and Microsoft
 are able to offer this feature with #350 notes software why can't
 Mapinfo.

An extremely reasonable suggestion! ( sorry for my bad English )
I hope you post it on the wish list of MapInfo.

Regards,
   Hiko

Re: MI MapInfo Compatibility Problems?

2000-05-31 Thread Adrian Walls

Yes you are right and why ???  I often simply edit the header info in 
the tab or wor to downspec the version statement and  I can open many 
new mapinfo files even in 4.1 , 4.1 16 bit  (which we use for a few 
custom mbx's we had built) , 4 for PowerMac and 4.5 so I can't see 
why MI cannot at least allow some backward compatibility.

If you of course are reliant on using some of the more obscure recent 
line styles improvements, thematic mapping additions or need the over 
36,000 node polygons and lines that may fairly well restrict your 
ability. Welcoming the improvements in linestyle sizes and options in 
4.5, we mainly use thematic mapping to alter line styles rather than 
in the basic data to ensure older versions can remain functional. 
Since my department budget for software was cut 60% this year I am 
looking at what maintenance contracts we have, and will be looking at 
sustaining a variety of version for a few another year since I simply 
make a bigger rod for my own back each time I upgrade mapinfo and we 
lose an existing user until this problem is resolved by whatever 
action. This is making this a real issue to me.

I do not see any good reason why in its 'save table as ', and 'save 
workspace as' options they cannot allow users to choose to save files 
as older 4.*  types not simply as version 2. If Adobe and Microsoft 
are able to offer this feature with #350 notes software why can't 
Mapinfo.

Is an answer needed!

Can someone please verify that MI 4.1 and 4.5 versions cannot open MI 5.5
tables and workspaces?  I have a co-worker in another city that says that
4.1 and 4.5 cannot open 5.5 workspaces and that 4.1 and 4.5 can only open
some 5.5 tables.
