AppleWin "Unable to capture PrintScreen key"

[Marco Verpelli]

My 2¢ on the argument.

I don't have a GitHub account so I write here:

OneDrive for Win10 "steal" by default the PrintScreen key, then after a (re)installation of Windows, hit that key and simply say no to the application.

Thanks, I've added your comment to the Github issue.

Seems like a common issue:

Not only OneDrive, Dropbox also take over the printscreen key, so maybe need to change the code and let users pick another key such as 'Scroll Lock' or 'End'.

Dropbox was the problem for me. You can turn the feature off in the Dropbox preferences.

One Drive have no option to turn off the printscreen capture, it's better to do it in AppleWin.

You can choose at the first use, or view then screenshot.

Find an image translator if you can!

Thank for the screen capture and I did found the option.

My point is these famous program (DropBox and OneDrive) use this key, and many people did prefer this key to work with DropBox, maybe people really enjoy screen capture goes into Dropbox, then why not AppleWin going flexible and provide a chance to change.

Maybe CTRL-PRINTSCREEN or something like that will be fine.

Rgds,
Johnson.

Since I originally implemented the PrintScreen key capture functionality in 2008 I can shed some additional light on this subject.

Back then DropBox and OneDrive weren't even around so there wasn't an issue of conflicts.

Second, due to Microsoft's inconsistent key handling in Windows we were forced to "register" an event to detect when the PrintScreen key is actually is pressed. Also due to Microsoft's brain-dead design only 1 program can registers this callback instead of properly chaining to ALL listeners. AppleWin detects if someone else has tried to take control of PrintScreen and will inform the user if it is unable to capture the screen -- since someone else already snagged it first. You can disable this via the command line option:

-no-printscreen-dlg

IMHO the proper solution would be to fallback to a "normal" function key -- along with having a menu option to take a screenshot. I'll have to see what function keys (along with Shift, Control, and Alt. options) are available. This would be a good "wishlist" feature to have down the road.

> Maybe CTRL-PRINTSCREEN or something like that will be fine.

Negative (for now.) Currently Ctrl-PrintScreen copies the text screen (it auto detect 40/80 columns) to the clipboard.

Again, ideally the user should be able to configure the two hotkeys they want to use. As noted, currently this is hard-coded. Having custom hotkeys is another "wishlist" feature to have but this will take some time to do properly.

I've amended Git Bug #380 with these feature requests:

Shift-F6 (or Alt-F6, i suppose) seems apropos, as F6 is already
associated with the screen.

[Michael AppleWin Debugger Dev]

That's actually not a bad idea Brian! I _really_ like the (base) mapping too since it is screen related.

We can't use Alt due to the it being used as Open-Apple = Joystick Button #1. We also can't use Ctrl-F6, but these are available:

* Shift-F6, and
* Shift-Ctrl-F6 are available.

I'll add this functionality for the next version:

* Shift-F6 Save 560x384 screenshot
* Ctrl-Shift-F6 Copy text screen to clipboard

Does anyone actually use the 280x192 screenshot functionality? I'm assuming that if you are taking screenshots that you probably also already know how to use GIMP or Photoshop. ;-)

[Michael J. Mahon]

True, but I've used 280x192 to save a step. ;-)

If there's config for the keys, we could have config in the same place for the type saved.

Though I've used Image Magick in the past with switches to automate reducing resolution like that. ; - )
