Do Wice support high DPI ?

[Charltsing]

I try 125% dpi , use Wice.Samples.Gallery

[smourier]

Wice kinda support Hi-Dpi in a sense that it doesn't honor it... ie: Windows and content are not resized proportionnally.

I don't have that issue though, here is a screenshot at 175% with a terminal and notepad windows for comparison

[Charltsing]

i try 175% dpi ,use the lastest Wice.Samples.Gallery.exe , Its richtextbox control displays incorrectly

my os is Windows 10 22h2

175dpi.zip

Maybe somthing is wrong in RichTextBox with High DPI.

[smourier]

I really can't reproduce that, here's a screenshot of my screen in 175% (w/o any DPI override applied on Wice):

My windows is also Windows 10 22H2 OS build 19045.3570

[Charltsing]

I know the cause of the problem now，need to modify advanced scaling settings-- Fix scaling for apps

cause.zip

So, how to make the software compatible with this setting?

OS also is Windows 10 22H2 , 19045.3570

[smourier]

That settings still doesn't change anything for me:

on:

off:

[Charltsing]

I found another problem， if i restart windows10 with 100% dpi , then change 100%-->125%, then mofify Fix scaling for apps setting, it is valid if i restart windows10 with 125% dpi ,then mofify Fix scaling for apps setting, it is invalid

Could you please send me the exe file and all dll files and .config file you are currently executing ? so that I can test and see if there are any differences in the file.

send to liucq@163.com or charltsing@gmail.com

thinks a lot

[smourier]

I have updated the Releases section https://github.com/aelyo-softworks/Wice/releases

[Charltsing]

i test windows 10, restart 100~125 dpi, problem is still present. win10 100~125dpi.zip

only restart win10 with 100dpi ,(if change 100% to 125% after started, Fix scaling for apps setting off ), it work fine

[Charltsing]

Why is the width of RTB different?

Fix scaling for apps setting is On or Off

[Charltsing]

https://learn.microsoft.com/zh-cn/dotnet/desktop/winforms/high-dpi-support-in-windows-forms I found that setting DpiAwareness and EnableWindowsFormsHighDpiAutoResizing in app. config has no effect on Wice(Disable app.manifest).

Maybe the winform controls such as RichTextBox should not be used in Wice

[smourier]

RichTextBox is not a Winforms control. Wice has no dependency over Winforms (except in some place for clipboard methods since there's no other way on Windows then use clipboard API, and Winforms wraps them easily).

The Wice RichTextBox visual does have a dependency on Windows' richedit (text services) implemented by msftedit.dll (https://learn.microsoft.com/en-us/windows/win32/api/textserv/nf-textserv-createtextservices). RTF rendering is far from being easy to implement in pure .NET.

it is msftedit.dll in my os msftedit.zip

riched.zip

[smourier]

I've tested with your msftedit (riched*.dll are not used they are legacy binaries) and it sill works:

Could it be the Windows regional settings/language/etc somehow? Maybe you can create a virtual machine (vhd) that reproduces the problem so I can have a look.

[Charltsing]

I install a english Windows10 22H2 (download from microsoft site, 2023.5.5), and insatll all online hotfix in a new PC, but problem is still present.

Start windows with 125% dpi( default Settings for Windows 10), run Wice.Samples.Gallery, after install hotfix finished I didn't do anything except above

so, i think maybe something have been missed

[smourier]

I've made a small change to the code (https://github.com/aelyo-softworks/Wice/commit/1e39a2bf7f5d2f37b75c1261665b6aa1b23b897c), bit of a shot in the dark since I've difficulties to reproduce the problem.

[Charltsing]

it works fine (150%DPI, Fix scaling for apps setting on) in my pc, thanks a lot!
