[Windows 10] no graphs in sysinformation Window shown in Tabletmode about systeminformer HOT 12 CLOSED

Have you tried any nightly releases?

I can reproduce this in 2.39 stable. Repo steps:

1. Click the Action center icon in the system tray (right next to the clock).
2. Click the Tabet Mode button.
3. Open Process Hacker and open the System Information window.

The window is blank and closing the window causes a crash.

I run the latest nightly (32Bit) compiled on my own with Vs2015 Upd2

problem is no WM_SHOWWINDOW message sent to PhSipSysInfoDialogProc in sysinfo.c.

if you move PhSipOnShowWindow(...) to WM_INITDIALOG it works, take it or leave it :)

from systeminformer.

Tablet mode should really be sending the WM_SHOWWINDOW message since there are likely thousands of other applications that will have similar issues.

from systeminformer.

ok, I've asked Microsoft and I got the answer, that it is by design, that the Tablet mode doesn't send WM_SHOWWINDOW message. So move it to WM_INITDIALOG. Here it works for me as @tigros figured out.

@MagicAndre1981 Did they tell you why it's "by design"?

from systeminformer.

nope, only that it is by design.

this quote was highlighted:

When a top-level, overlapped window is created with the WS_MAXIMIZE

so Tablet mode seams to activate this.

out of curiosity i looked up what reactos is doing, so for all the dirty details go to line 2426 of https://doxygen.reactos.org/d0/dcd/ntuser_2winpos_8c_source.html

cheers!
