Windows 10 - Freaky Scaling issues (in non-SetupBuilder application)

[NewsArchive]

We have a few customers that have been complaining about a problem
with window scaling of our app on their Windows 10 machines.

When a particular window would open in our app, the entire app would
shrink down, including all fonts, etc. This makes the app almost
unusable.

I haven't narrowed down the exact cause in our app that makes it
shrink yet, but at least I can duplicate the problem now - thanks to
our support staff. This one really had me befuddled.

Here is the page to look at if you see anything similar.

Is the window in question so large that Windows needs to reduce it to
fit the device and therefore shrinks the entire APP?

No. Disabling Scaling at High DPI on the compatability tab of the
shortcut "fixed" it.

My guess is that a com object that I call is calling
SetProcessDPIAware() or something like that.

Maybe we can fix it in the app manifest. I don't see anything in SB
about that.

Thanks. I guess SB should do that for me, if it checks for app version
anyway.

SB supports it. Add the "#embed UAC manifest..." and the DPI-aware is
in the lower right corner.

However: I tested the manifest setting on my laptop (NOT from SB, just
my own) and it never made any difference no matter if I followed the
recipe to the letter. So, I don't know if the manifest setting actually
helps with the problem.

Best regards,

For my particular problem. Setting the DPI-Aware thing solved it.
Wonder when Friedrich did that and if anyone else went through my same
fun.

Awesome! It was added last summer:

SetupBuilder 2016 Version 10.0 Build 5203 (July 07, 2016)
----------------------------------------------------------------------------

NEW : IDE: Add 'DPI-aware' element option to the "#embed UAC
manifest..." compiler directive.
