QUESTION
To handle file uploads on a website we have to use a hidden element.
To find out what file has been selected in the Select File Dialog, we can use the onchangeevent.
But how can we detect if the user has hit the cancel button?
Unfortunately, there is no oncancel event.
There exist a lot of workarounds to detect if the user has hit the cancel button, but due to the problem I described here, none of them worked for me reliably.
...ANSWER
Answered 2022-Mar-11 at 08:26I've invested countless hours looking for a solution. And now I want to share my solution with you.
I use three event handlers:
onchangeevent on the file input: To detect when a file has been selected.onfocusevent onwindow: To detect when the Select File Dialog has been closed.onmousemoveevent ondocument.body: To detect when the interaction is not blocked anymore. Only when this event is called, you can be sure that theonchangeevent of the input element has been called.
The first two points are obvious and you find them in most proposed solutions. But the crucial point is number 3. In other solutions I sometimes faced the problem that I selected a file, but this selected file has not been propagated to the onchange event handler before window's got focus.
To make a long story short, here's my implementation:

QUESTION
I'm trying to print the PDf-file(s) in a certain folder (or alternatively just print the files one-by-one) using for example Micorosft Print to PDF in order to create flattened versions. However when using Microsoft Print to PDF i need to specify the ouput-file's name and path. Is there any way to circumvent this or an alternative virtual printer specialized on such a job?
What I've already tried:
Windows 10 Print to PDF from command-line and Printing PDFs from Windows Command Line
These approches try to use the command prompt (personally favoured by me aswell, as it allows to create a batch-file and automate the process completely), but unfortunately the programs/printers listed in those posts are either not free or show a save-file-dialog aswell. Furthermore they are quite slow (even though this is not my main focus). So far, PDFtoPrinter has been the best solution, though it shows the save-file-dialog aswell...
Another idea I got from this post is to create a (VBA-/PowerShell-)script, but I'm not very experienced at that.
Any way to print just one PDF via the console and then making a loop or maybe even hard-coding the names would suffice aswell. I can easily rename the files for example to 1.pdf, 2.pdf, 3.pdf, ...
At this point I've tried so much but there has to be a way to get this running. Any help would be greatly appreciated!

Answered 2021-Dec-18 at 23:55Microsoft Print to PDF on Windows is not "Free", simply "Leased", however that said you can change the owners designed behavior to a different "port" than "prompt" or use the drivers to print to your desired named file.
To use ONE fixed output filename like %TEMP%OUT.PDF you are best served by cloning/duplicate the "Microsoft Print to PDF" to a printer name of your choice so I call mine "My Print to PDF" as its shorter to type and the Auto printed file goes to MyData folder. For a visual guide see https://stackoverflow.com/a/69169728/10802527 and up vote there if that helps.
The alternative is to use a structure like
QUESTION
Using the simple file dialog on MacOS allows me to use ⌘ + O to open either a file or a folder.
But on Linux (or Windows), I have to use CTRL + K → CTRL + O if I want to open a folder, or just CTRL + O to open a single file. This is frustrating, and I always forget it when I jump from my MacOS work-machine to my personal Linux machine.
On Linux, it looks like this for files:
Since this is a VSCode in-application dialog (not an operating system dialog), there shouldn't be any operating system limitations to it.
Is there any option to enable the MacOS-style combined behavior for it?
...ANSWER
Answered 2021-Dec-19 at 01:57OK, so it was much simpler than I thought.
There is a keybinding for this, it is simply called "File: Open" under "Keyboard shortcuts", and its full name is workbench.action.files.openFileFolder.
It currently has the when-constraint isMacNative && openFolderWorkspaceSupport, but you can simply remove this by right-clicking the binding, and selecting "Edit When Expression".
Then simply bind it to CTRL + O or whatever you desire.

...ANSWER
Answered 2021-Sep-22 at 12:26In an MVVM architecture you would usually find parsers in the Model component. The View Model generally does not process data. Usually it may convert data to meet the constraints of the Model's interface or to prepare data for presentation in the View.
Also from an MVVM point of view the data source and sink is always part of the Model. It does not matter whether data comes from a database or from a file picked by the user.
QUESTION
Goal: using python, I want to open a Powerpoint presentation and print it using the "Microsoft Print to PDF" printer. I do NOT want to export it as PDF, I want to print it using Print to PDF. This is not a duplicate of this question.
Why: I have found that in my use case that Print to PDF gives better image quality, whereas Export as PDF is overly compressing the content. Also I do not have Acrobat Pro, so I have no way other than the Office default to export files to PDF. (For those curious, I have a large .pptx (12Mb, due to some high quality images). Export to PDF generates a PDF that's 1.4Mb large, Print to PDF generates another that's 1.8Mb. The image quality difference is such that one is ok, the other one is not).
What I have done: I've figured out how to Export as PDF with help from this question (but using win32com instead of comtypes).
I then tried to change things around so that I'd print instead of save, something like this:

It turns out that the attempt to use PrintOut was correct (doc here)! However I believe this method behaves asynchronously, so in the snippet below:

Answered 2020-May-13 at 14:07Electron doesn't allow windows with webSecurity: true to load files. You could simply set it to false and get rid of the error but it would make your app unsafe to use.
Instead, what you have to do is to create a custom protocol and then use that for loading files.

I'm following the dialog example for opening files from: https://github.com/electron/electron-api-demos
I copied the code from the example. The open file dialog does in fact work and I'm able to select a file but can't figure out why the arrow function to send the file path back to renderer doesn't work(nothing is logged with console.log).
Can anyone spot what's wrong? The project was started using electron-forge and my OS is linux. Thanks

...ANSWER
Answered 2020-Feb-12 at 16:17The dialog API has been modified with the release of Electron 6.
dialog.showOpenDialog() and other dialog functions now return promises and no longer take callback functions. There also are synchronous counterparts which return the selection result in a blocking fashion, e.g. dialog.showOpenDialogSync().
