Hi folks,
Could really use some guidance to point me in the right direction.
h*tp://mvsoft.com/pub/eqs/eqs57dem.zip
It's a 16bit app, which says its a demo but at least some of the code for the full version seems to be present. It creates an Ini file in c:\windows on installation but this never gets read on loading the demo (it is read in several functions such as 'about' and there is an annoying space for the serial)
There are numerous dll's but only two are read on loading xwmba423.dll & xwmte423.dll.
Save,print,cut & copy are menu disabled and there are limitations on the size of models the demo can produce.
At first I tried to get back to the protection via the 'can't print...' nag but just keep getting lost in the code - the first couple of conditional jumps don't seem to make a difference. I also tried bpxing on enablemenuitem & enable window but no luck.

Modifymenu is called on load from xwmba423.dll but again I kept getting lost in the code.
I tried stepping thru from the ep for the best part of a day but them thar codewoods..

Any help would be welcome

Still no further with this one but I did manage to get back to the print menu select from the 'can't print' dialogbox breaking initially on 'dialogboxparam'.
The sequence of segments/files from the calls in the first part is:

Dmas.exe Seg 1:1301
Dmas.exe Seg 1:34c4
Dmas.exe Seg 15:4baa
Xwmba423 Seg 94:818
Xwmba423 Seg 13:22e
Xwmba423 Seg 94:830
Dmas.exe Seg 15:4bca
Xwmba423 Seg 87:07ac
Xwmba423 Seg 11:0000
Xwmba423 Seg 13:4b6
Xwmba423 Seg 11:0011
Xwmba423 Seg 87:07c9
Dmas.exe Seg 15:4c1b
Xwmba423 Seg 94:8e6
Xwmba423 Seg 13:22e
Xwmba423 Seg 94:8fe
Dmas.exe Seg 15:4c29
Dmas.exe Seg 1:34f1 etc.
I've tried to compare the sequence with the disabled controls like this one with a couple of good ones but can't see it.
