Adjust Display Scale of Lineweight Settings dialog... again

Me again, with my Display Scale Adjusting quiz...

The question was - how do I programatically, by any means, change the value of Adjust Display Scale slider in Lineweight Settings dialog?

Bill and Tony replied that there's a registry entry:
HKEY_CURRENT_USER/Autodesk/AutoCAD/VERSION/FLAVOUR/Profiles/PROFILE/General/LineWeightDisplayScale
that keeps track of the value. Alas, I tried to set it up in various ways, but the lineweight display scale stays the same on the screen (regen doesn't help). I even tried to set it (to DWORD 4) and then create new ACAD profile using existing settings, but the newly created profile just somehow continues to keep the original settings.

As far as I see, I'll have to implement VBA sub that launches Lineweight Settings dialog, then searches for the dialog via API, finds the slider control inside it moving it to desired value somehow... (setting focus and playing a sendkey sequence)... Oh no...

Thanks for any tip on this.

You must be doing something wrong.

AutoCAD reads the registry for that value
before displaying the dialog box.

What I haven't checked is if the value is kept
and updated in memory during the acad session
but I doubt it.

Jorge,

This is what I tried till now:

First check for existance of LineWeightDisplayScale registry value of "General" key within current profile. If there's no such value (originally there's none), I create it and set it to DWORD 4 (only that value works for me). So, here's what I did then...

1) If reg. key exists, I change the registry value from hex 1C (original setting) to 4 (DWORD). Nothing happens within drawing, display scale stays the same. It's still 1C when I open the dialog again using "lweight". Regen doesn't help. When I recheck the registry value, it's 4 (as it should be). Dialog simply ignores my manual registry setting.

2) Change registry value, shut down the ACAD. When I reopen ACAD, nothing happens (!) - even when there's correct value stored in registry.

My conclusion - there must be some other (registry or .ini based) value that also keeps track of LineWeightDisplayScale setting. BTW, there're no code flaws and explicit + debugging are on.

Please help, it drives me nuts.

Maksim Sestic

Have you tried doing that manually ???

If you shut down AutoCAD and change
the registry value to 2, then open
AutoCAD, you should get the lowest
value on the displayscale bar. If you don't
then you're changing the wrong key.
A value of 4 should display the second notch
on the displayscale bar.

Like I said before I haven't tested if the
value is cached and not read until the
next session, but if you're changing the
value while AutoCAD is running and nothing
happens, then ACAD reads the value only
once, and writes the final value when closing
the session.

There are temporary values that are added to
the registry when this dialog box is open and
closed. When the acad session is closed, those
values are deleted. You should check to see if
one of those values is a temporary storage
for the displayscale.

Jorge,

It was so obvious and you're right - ACAD reads the display scale setting at the moment it's fired up for the first time. Then it keeps the slider's setting in some temp variable and writes it back to the registry as the user either shuts down the ACAD or switches to some other profile.

Funny thing is that I coded the registry checkup/change as the ACAD is already up and running (though it's invisible to the user and in zero document state). Alas, at that point the registry value is already "read" and stored to that nasty temporary var. I just re-coded the part "what happens when" and it's working fine now

Thanks again,
