[DUG] Windows 10 issues

[John Bird]

Some progress:

Delphi 2007 now working again, and the fix was simple - run the install again and take the repair option.  Was quick, and just needed some setup files into some of the .NET folders I am guessing.


Windows setting (right click desktop/Display settings)
"Change the size of text, apps and other items: 100% (Recommended)"

The settings of the "Make Text and other objects larger"  to 125% is quite a puzzle.   Windows 10 does it by not by increasing the DPI - it reduces the size of the screen.

I have a program to display many of the screen parameters that Delphi can use - here are interesting results - compiled under XE8

With  text size at 100%  then  screen.width and screen.height are 1920 x 1080
When text size is 125% then screen.width and screen.height are 1536 x 864

This means it is effectively setting the screen to not its native resolution.

Similarly screen.pixelsperInch remains at 96  (on Windows 7/8 it altered to 120DPI for text size at 125% I recall).

TOSVersion.tostring  reports Windows 8 (version 6.2 Build xxxx)   so to report that the OS is Windows 10 requires extras in building the program.   I would rather like to get better information on this.

If others are interested I have screenshots of the program running under different settings, and the smudging of fonts at the higher text size is obvious.

I also noticed some quite basic things like when set at text size 125% then with the mouse over a window close button the red flickers on and off.    The impression is that Windows 10  is really only designed to be set at text size 100%.   This means that with a HD screen icons and default text are small but sharp.


As far as Network and Wireless drivers for Windows 10 - no progress after 2 hour long calls to HP support.   I have seen googling that problems with network and wireless drivers is common with HP laptops in the last day.   Looks like they were just not ready with the drivers so be cautious.
