Hi,

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

MorphicUIManager new fileSave: ''

In old win32 vm (Oct 12 2016) I am placed in the image directory and I see the whole hierarchy ​ <oldvm.png>

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

<newvm.png> ​ My own FileDialog implementation doesn't suffer from this, so maybe the Morphic one is just accessing the data in a weird way?

I think is a regression in FilePlugin… no problem with morphic… but now I’m not sure anymore. You made me doubt :)

ps: FilePlugin is having problems anyway… I was expecting to work on it next week.

I can create a patch with the proposed solution.

2015-11-06 8:42 GMT+01:00 Nicolai Hess <nicolaihess@gmail.com mailto:nicolaihess@gmail.com>: we have the following bug report 16928 https://pharo.fogbugz.com/f/cases/16928/no-disk-in-the-drive-reply-to-World-Save-As-and-other-places "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 http://bugs.squeak.org/
