Drag-and-Drop with Desktop files
Sub-Subject: Detecting user selected files/folders in Windows and other
OSes.
I like to refer to the last message from -hh (see reference below)
regarding Windows possibility of detecting selected items (folders, files,
icons as such) on the Windows Desktop. The solution -hh already provided
when items are selected in any Windows Explorer. The Desktop is not part of
that and basically a special Windows ListView control.
It is correct that items selected on the Windows Desktop are deselected
when another window is becoming active. So, using LiveCode would not work
this way.
What could work though is a service that is running in Windows OS and
detects selected items of the Windows Desktop and their status of type,
selection and position, etc. The service could be started when opening
LiveCode and shut down when closing it. Data would be saved to a temporary
file.
So, switching focus to the LiveCode window would allow reading the temp
file with the list of selected items that have been selected BEFORE the
user activated the LiveCode window.
It is too much of a hassle at the moment for me writing such a program that
runs in the background. Nevertheless, for C/C++ and C# there are some code
fragments around that are public and doing just that.
For my clients, it is a very good solution to be enabled now to select
files/folders and read their path into LiveCode. For Desktop items in
Windows, I just tell them to move them into a folder and select them within
this folder (which is then an Explorer window). So, that works with scripts
-hh provided.
THIS IS MORE CONVENIENT THAN DRAG-AND-DROP of files/folders even though I
also support drag-and-drop plus the standard file/folders selection window.
Many thanks again. And I hope the same will work on MacOS and Linux as -hh
also provided solutions there, and I saw others providing. (I am not using
both others OSes since my clients are 100% Windows only.)

Re: Drag-and-Drop with Desktop Files
I had drag and drop in my macOS app but … when going with the AppStore, and
sandboxing, there was no way for drag and drop to trigger the sandbox
permission that would allow the app to read that file. I knew which file, but
since it did not go through the dialog box, the permission wasn’t set.
So I took drag and drop out of my app and it passed store app review.

Re: Drag-and-Drop with Desktop Files
Hi,
I use MacOS or linux (on Raspi only), never really worked with windows.
I'm using Windows only to test my stacks/apps on the PC of my youngest son.
Scripting Host-WScript can execute JScript, the MS-extension of ECMAScript. It
has a
lot of features. We probably can use a lot of these features via LC's shell.
I looked into that out of interest the first time last week. It is well
documented:
https://docs.microsoft.com/en-us/windows-server/administration/windows-commands/wscript
And it seems to be better maintained than VBScript.
But there is NO method to get the selectedItems from the virtual desktop folder.
Moreover, as you may notice, the selected items are deelected when you activate
another window (as for example a LC window or an explorer window).
The only workaround I can see (besides using an answer file dialog or dragDrop)
is:
1. launch document specialFolderPath("Desktop") --> open desktop folder in
explorer
2. User should select the files in that window.
3. Use the already working method for explorer windows.
file "wscript1.js" (more compact output)
var shellWindows = new ActiveXObject("Shell.Application").Windows();
for (var i = 0; i < shellWindows.Count; i++) {
var w = shellWindows.Item(i);
var sel = w.Document.SelectedItems();
for (var j = 0; j < sel.Count; j++) {
var item = sel.Item(j);
WScript.StdOut.WriteLine(item.Path);
}
}

Re: Drag-and-Drop with Desktop Files
hh, I have one more question for Windows: Selecting a file through
Microsoft File Explorer on Windows 10 works for all selected files with
your wscript, also when it is a Desktop file accessed through the dialogue.
The problem I have is when the user selects a file _directly_ visible on
the Desktop, wscript will not catch the file. Is there a way to find such
selected files on the Desktop when users just selected files there? I am
not familiar yet with wscript.
And I can not catch this attribute using the
files(specialfolderpath("desktop","detailed")) function in LiveCode.
Thanks, Roland

Regarding MacOS I can not say much, but I use Windows, and IT WORKS.
'hh ' = Hermann's contribution, right? This fantastic. I never expected
anybody to have a solution. I had searched Git and whatever.
Well, first it did not actually work because spaces in the folder- and
filenames are breaking the script. There will be an error message. So, I
have added these script lines to what 'hh' had posted:
-- Button script
on mouseUp
set the hideConsoleWindows to true -- Hide console window
put the effective filename of this stack into p
set the itemdelimiter to slash
put "wscript1.js" into last item of p -- Or construct any other valid
file path
--replace slash with backslash in p -- Not needed, works without
backslash conversion
put quote & p & quote into p -- Required if file- or folder names
contain spaces, and mostly they do
put shell ("wscript ") into msg -- or any field, ...
end mouseUp
Tested:
Operating system: Windows 10, the latest version
OS scripting language: Wscript (Microsoft Windows Script Host File)
Filename of script file: "wscript.js"
Location: Here the call file is placed inside the stack folder (could be
any other location)
Script of the file as given by Hermann:
var shellWindows = new ActiveXObject("Shell.Application").Windows();
for (var i = 0; i < shellWindows.Count; i++) {
var w = shellWindows.Item(i);
WScript.StdOut.WriteLine(w.LocationName);
var sel = w.Document.SelectedItems();
for (var j = 0; j < sel.Count; j++) {
var item = sel.Item(j);
WScript.StdOut.WriteLine(item.Name);
WScript.StdOut.WriteLine(item.Path);
}
}
Biggest THANK YOU. You solved the client request in a very elegant way and
I create this script file "on the fly" from within LiveCode and execute it
on the client's Windows system.
Thanks for all contributions

Drag-and-Drop with Desktop Files
Jacqueline: on dragDrop -- check for file paths get the dragData["files"]... pass dragDrop end dragDrop Jacqueline, thank you. I know this and wrote about it. Here I want to know the filename and path which is user-selected in the OS (on Windows File Explorer) without dragging and dropping it to the LiveCode window. I am looking for a Powershell function that can be invoked in LiveCode. I failed to do this so far even though trying. How do we call Powershell in LiveCode? I can do it with Shell functions and with outdated VBScript. If I get it working myself, I will post it.

Desktop and IDE, mainly Windows 10 (could be any OS), LiveCode lastest version. Drag-and-Drop on Windows works as expected. But I have another request and do not know how to handle it so far.

As far as I know, VBScript is deprecated. How would we call Powershell and receive information in LC back from Powershell? Powershell does not appear in the list of supported scripting languages of the OS when calling "alternateLanguages". ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
