Hi,

I think a regression occured in Pharo VM related to this, for example when I open the dialog

The whole "posixpermission" code seems to be removed from the windows file plugin code (sqWin32Directory.c)
And as the "old" file dialog opens only readable directories it does not show anything because all entries have posix permisson 0 -> not readable.
But it is still possible to list the directoriy contents.
��

MorphicUIManager new fileSave: ''

In old win32 vm (Oct 12 2016) I am placed in the image directory and I see the whole hierarchy
���

but with new VM (Jan 14 2017) I see just an empty tree with only hard drives available


���
My own FileDialog implementation doesn't suffer from this, so maybe the Morphic one is just accessing the data in a weird way?

Peter

I think this could be applied on pharo win32 source as well.
maybe with some small changes

I opened another bug report at mantis - > http://bugs.squeak.org/view.php?id=7841

I can create a patch with the proposed solution.

we have the following bug report
16928 "no disk in the drive" reply to World | Save As (and other places)

"On a clean Pharo4.0 #40618 image, on Windows 7
World Menu | Save As brings up a modal alert window, "There is no disk in the drive. Please insert a disk into drive <etc>"

On my system, it does this 4 times.��

I'm assuming that each instance refers to one of the card-reader drives which are attached, but without a card inserted.

This is a pain to deal with every single time a File Browser or World | Save As dialog is opened.

Could the alerts either be
��- only raised when that specific drive is requested by a user action
or, less preferably
��- given by a non-modal window, and fading away after a period"

I was able to reproduce this error on squeaks and pharos window vm.
(insert a usb card reader, with card, wait some time , remove only the card,
every access on this drive, for example open a FileList and scroll to the drive letter).


The solution I found is to call SetErrorMode(SEM_FAILCRITICALERRORS)

I would like to propose the following change to sqwin32directory.c
wrap the call to FindFirstFileW/FindNextFileW with

UINT prevMode = SetErrorMode(SEM_FAILCRITICALERRORS);
call���� FindFirstFileW/FindNextFileW
SetErrorMode(prevMode);

...

and call this functions in at least dir_lookup()
(the other file/directory methods are save).

Alternative solution, we could call the SetErrorMode function once at program start
but I don't know if there are other "useful" errors message that we don't want to disable.

I tested both solution, both seems to work fine.

What do you think?







Any chance to include this�� ? Or is it already done, if so I can close the issue at pharo.fogbugz���� and bugs.squeak.org
