Notepad++ release 8.9.9

andrecool-68

If the Notepad++ window is already open, then the file (ANY) does not open at all through the context menu. If the Notepad++ window is closed, open it through the context menu. This appeared only in this new version; if you take any older version of Notepad++, then such a problem was not observed.

I checked ‘Notepad++ Release Candidate 2 v8.9.9’, and it turned out that this version does not have this problem at all, unlike the final version.

At least in the Find dialog, there is a cosmetic change: A thin, solid black horizontal line now sits just below the “Search Mode” and “Transparency” group boxes. Was the change intentional?

Version 8.9.8.1:

Hello, @peter-fb and All,

I did not notice any change at all, even after modifying the new option in Settings > Preferences... General > Dialog Font

@guy038 Your Find dialog is transparent, but it seems to look just like mine does in version 8.9.9. The other ones are fine on my side, too.

@andrecool-68 ,

~~Are you sure? …~~ {deleted my original answer}

see @donho’s answer, below… my memory seems to be wrong; and like Don, when I try to replicate it (rather than going off of memory) with my installed 8.9.9 running in Admin mode, whether I open a protected file or a non-protected file from explorer, Notepad++ opens it just fine. (I was apparently misremembering things)

I am not sure when Notepad++ assigns the font to the various dialogs. It may have already assigned fonts when it created the dialog (maybe even behind the scenes), and not dynamically changed them. If you exit Notepad++ and restart, it should take effect.

When I did:

Open Notepad++
Open FIND, take screenshot, close dialog
Set General > Dialog Font = Comic Sans MS
Open FIND, it’s still original font
Exit Notepad++
Open Notepad++
Open FIND. it’s Comic Sans MS now, take screenshot

Continuing the procedure:
8. Exit Notepad++
9. Run Notepad++
10. Set General > Dialog Font = Segoi UI
11. FIND => still shows comic sans
12. Exit Notepad++
13. Rerun Notepad++
14. FIND => back to normal UI font

It appears that, at least for some dialogs, that option requires restarting Notepad++.

Official released Notepad++ v8.9.9 opened in Administrator mode from C:\Program Files\Notepad++\notepad++.exe,
and I cannot reproduce the bug you reported - File is opened as expected.

One thing you should ensure that the opened Notepad++ path should be the one that NppShell.dll points to (Normally C:\Program Files\Notepad++\notepad++.exe), otherwise the operation will be abandoned for the security reason (harden in v8.9.9).

@peter-fb

The “culprit” is:
https://github.com/notepad-plus-plus/notepad-plus-plus/blame/master/PowerEditor/src/ScintillaComponent/FindReplaceDlg.rc#L93

It was introduced at least 16 years ago for being able to use ALT+y to check/uncheck Transparency checkbox.
So it’s rather a feature, not a bug.

@donho And it somehow only shows up now with version 8.9.9, not with version 8.9.8.1. Do I understand that correctly?

I always have the portable version in which there is no NppShell.dll file at all, and for many years I have added Notepad++ via a batch file. These problems only started in the final version.

REM Open file in Notepad++ (Открыть файл в Notepad++)
Reg.exe add "HKCR\*\shell\Open file in Notepad++" /v "Icon" /t REG_SZ /d "%~dp0notepad++.exe,0" /f
Reg.exe add "HKCR\*\shell\Open file in Notepad++\command" /ve /t REG_SZ /d "\"%~dp0notepad++.exe\" \"%%1\"" /f
