I am dragging and dropping a text file into a field using:
Code: Select all
on dragdrop
put dragData["files"]
end dragdrop
Works fine except it does not convert not ascii chars like ö. What is the solution?

Hi Kaveh,
you little script will only put the filename of the file into the message box.
What do you script to get the file into the field?
In any way you will need to -> textdecode("... content of file....","UTF8")
before putting into a field.

You are a genius Klaus!
First of all, apologies. I copied wrongly. This is what I was using:
Code: Select all
on dragdrop
put URL ("file:" & dragData["files"]) into fld "original"
end dragdrop
Now I use this which works.
Code: Select all
on dragdrop
get URL ("file:" & dragData["files"])
put textdecode(it,"UTF8") into fld "original"
end dragdrop
Thanks again.

Hi Kaveh,
to avoid surprises I always use ->
line 1 of the dragdata["files"]
Unless my script(s) exspect more than one file.

You know something? That is exactly what I had! Must have been advice from you years back. I could not understand it so changed it and it worked.
Could you kindly explain what is going on there? Why would there be more than one line and why do we take the first line?

Hi Kaveh,
the dragdata["files"] can contain more than one file per line!
I made a little test with a button and dropped some files on it:
Code: Select all
on dragEnter
set the dragaction to "copy"
end dragEnter
on dragDrop
put the dragdata["files"]
end dragDrop
And ended with this in the msg:
/Users/klaus2/Desktop/Linie 5x ab Hasetor.pdf
/Users/klaus2/Desktop/M1 Vitihof -> City.pdf
/Users/klaus2/Desktop/Neue Filme November 2021.rtf
/Users/klaus2/Desktop/monty.jpg
I think this speaks for itself!
We all know how users are, so this is neccessary in my opinion.

So am I right that you want to ensure only 1 file is acted on, in case user drops more than one file? In that case would it not be better to warn the user rather than take one of the files, namely the first one in the list?

Exactly!

You decide for your app.

What happens when you drop three PDF document icons onto the Adobe Acrobat app icon?

Acrobat will open all three files.
But this is a Livecode forum and not a quiz show, Richard!
I gave some advice since Kavehs script obviouly only exspected ONE file.
So I wrote:
to avoid surprises I always use -> line 1 of the dragdata["files"]
Unless my script(s) exspect more than one file.
I am sure Kaveh now knows that one needs a repeat loop if the user drops
more than one file and the script wants to accept and process all of them.

It's a question of designing apps that work as users are accustomed to seeing.

Yes, Richard.

Hi Richard
The problem here is that I am dragging a file into a field. Allowing multiple files would be confusing. So it is quite logical to say you cannot drag multiple files. I am now using:
Code: Select all
on dragdrop
get dragData["files"]
if the number of lines of it > 1 then
answer "Please drag in only one file"
exit dragdrop
end if
get URL ("file:" & the dragData["files"])
put textdecode(it,"UTF8") into fld "original"
end dragdrop

Hi Kaveh,
hint:
Do not use IT more than neccessary, since IT may change when you least exspect IT!
Use an extra variable, which fortunately does not cost extra money:
Code: Select all
on dragdrop
put the dragData["files"] into tFile
if the number of lines of tFile > 1 then
answer "Please drag in only one file"
exit dragdrop
end if
put URL ("file:" & tFile) into tFileContent
put textdecode(tFileContent,"UTF8") into fld "original"
end dragdrop
