Horst...

> which print setup dialog do you mean?

I was talking about the one you get when you call PrintDlg or PrintDlgEx.
That's if you want to be able to change the printer interactively. If you
want to simply change it behind the scenes, then Paul's method is best - use
the WshNetwork object. If you don't have or for some reason can't use that,
give SendKeys a try. If that won't work for some reason or if you just want
to understand what's happening, write the default printer of choice to
win.ini and notify the VEE runtime of the change. See my reply to Paul's
message.

Come to think of it, you can do it with ExecuteProgram too. And no, I don't
mean running another instance of VEE. Geez! that's about the craziest thing
I ever heard. But yeah, I heard it too. Long ago. That's when I quit
listening and started looking at it from a Windows programming point of
view.

Hell, if all those methods don't work for you then get your window handle
and copy the bitmap off of it. Scale it how you want, dither it how you
want, do whatever you want to it and BitBlt it to the printer of your
choice.

In any case, you are most definitely not limited to the printer the VEE
runtime starts out with! This is PROGRAMMING!! You're limited only by your
imagination.

Use the "toFile" object instead of the "toPrinter" object. Then you are able
to send the escape sequences to your printer.

Betreff: [vrf] printer scaling and orientation at runtime?

Hello vrf users,

does anybody know if there is any solution to change orientation and scaling
of a function
panel printout at runtime? Selectable by the user or simply by the program
if appropriate?
Is it possible to get rid of the unwished time stamp on the printout?

Greetings

Hello B. Aufenanger,

thanks for your response. But (hello agilents =:o)this is solid work down to
the roots
of printing. In my opinion it should be possible to print e.g. images
and graphs stored within different panels independent from the orientation
and dimensions of that panel just by scaling and rotating
it programmatically. It seems that at runtime by no means not even changing
of the
printer is possible, its always the standard printer at start up of the
program. Or have I overlooked something?

regards
Horst

Betreff: [vrf] Printer scaling and orientation at runtime?

Hello list,

i did have similar problem in the past and got the following hint from
Agilent:

1. basic problem is windows itself as it uses just one printer during one
session.
With Vee you can declare one printer with orientation and scaling which fits
to your needs.
2. If you need different outputs (print designs), the only chance you have
is to use a new vee program with a different "standard printer design". Then
you can call the Vee-No2 program from Vee-No1 program and so on.

I did try to use some Windows library functions according to the microsoft
help list, but it does not change the standard printer during vee runtime. I
think the solution above is currently the only one i have heard of. I also
hope to get new infos and maybe some update with better support in that area
from Agilent.

My problem was that i wanted to print my data on paper and simultanously as
a pdf file with Acrobat. Now you can get a program for 50 Euro which did it
automatically, but in the past the run of 2 vee sessions was the only
solution for that.

As i am a " rookie " on this list, i apologyse for possible mistakes ;.)

Best regards,
detlef

Shawn...
Seems to be a misunderstanding-

Question is how to change the printer output automatically- without any
mousemovement and clicking the mouse-buttons.

The problem is that Vee uses the standard printer for the whole vee-session
-
a change of the standard printer via windows functions ( which are different
for the different Windows versions) did not change the standard printer for
the started Vee-Program. Thereore the described solution.

To make it clear here one example:

You have a panel which you want to print out on paper via lets say printer1
, and you want to print out the same thing via printer2 which is i my case
the Acrobat distiller.
And you want to do it WITHOUT any additional clicks of checkboxes and
manual change of standard printer device.

I have seen that you currently recommend a Keyboard Macro Program- thats one
possibilty.
Do you see others ?

Best regards,
detlef

WHAT?? That's TOTALLY INSANE. No, that's not the case at all. Use the print
setup dialog. You'll have to change the default printer.

As for producing a PDF file, if I remember correctly that's just selecting a
different printer, right?? What Windows functions did you try to use?

Hello Shawn,

which print setup dialog do you mean? I can change the default
printer within windows or change the current printer within
other programs like winword a.s.f. but while running a VEE
program VEE sticks to the printer set at start up.

That's ok, practical examples keep me on my toes. If that doesn't work out
for you, post again and I'll work up an example of printing graphics from
VEE without using any VEE services what so ever! And probably without using
a custom dll, if I can manage it with VEE 5. GDI programming is a real
hoot - I bet everybody would love it.

Thank you Georg. I wonder how V5 figures out which convention to use if you
don't specify? Maybe I just never ran into the problem. Oh well, I guess I
can just build a few dlls and find out.

Hi Shawn,

this seems to be a powerful function.
I've problems running it in Vee Pro 6.03, since
the 'class name' seems not to be Agilent_VEE,
neither VEE PRO or similar.

How to find such a class name ?

Thanks & cheers,
Werner.
