Re: Drag & drop a file - what am I missing?

[Jeremy French via 4D_Tech]

Hi Pat,

Take a look at the documentation for "Get file from pasteboard” at:
https://doc.4d.com/4Dv17/4D/17.2/Get-file-from-pasteboard.301-4387094.en.html 


Put the following in the object method of a text variable and drag a file atop 
the text variable. Remember to check-mark the “On Drop” form event.
—
Case of 
: (Form event=On Drop)

OBJECT Get pointer(Object current)->:=Get file from pasteboard(1)

End case 
—
The text object will display the file’s absolute path.


Best regards,
- Jeremy

Re: Drag & drop a file - what am I missing?

[Chip Scheide via 4D_Tech]

Pat,
not using v17 - but yes.

I have never tried picture dropping, but I was unable to get Drag N 
drop to function to a field.

I work around this (and it makes the target easier for the user) by 
using an invisible button which covers a section of the screen so that 
the user can drag n drop anywhere in that area, rather then just on the 
(small?) field.

You can easily place the path into the desired text field after 
validating the drop.

Drag & drop a file - what am I missing?

[Pat Bensky via 4D_Tech]

Using v17 -

Until now I've implemented drag & drop between objects, for example list
boxes. No problem.
But now I want to allow the user to drop a file onto a field and save the
file's pathname in the field. I cannot get this to work and indeed the docs
imply that this should only work with variables and objects:

"For example, it is possible to drag and drop a PNG picture file onto a 4D
picture field. It is also possible to select text in a word processing
application and drop it onto a 4D text variable or a list box."

So you can drop a picture onto a picture FIELD but any other type of file
(eg .txt) only onto a variable?

Re: [Tip]Set Query Destination

[JOHN BAUGHMAN via 4D_Tech]

I use a macro whenever I call SET QUERY DESTINATION…




SET QUERY DESTINATION(;)

SET QUERY DESTINATION(Into current selection)

So if I write…
Query([Patient];[Patient]Dentist_Name="John Baughman")

Then realize I need to a query destination other than the current selection I 
highlight the above line of code and call the macro, I get…

SET QUERY DESTINATION(;)
QUERY([Patient];[Patient]Dentist_Name="John Baughman")
SET QUERY DESTINATION(Into current selection)

Cursor is now right after the first open parenthesis. Never miss putting it 
back to current selection.

Hope someone out there finds this useful.

John

'Clairvoyance' in listBox (v17r5)

[Chris Belanger via 4D_Tech]

I would to:
• click a listbox (to ‘focus’ on it)
• type - and have it automatically search in the list and highlight the closest 
match.

Of course, this is common in ’traditional’ apps.

For many years, I have jury-rigged this by using a ‘quick scroll’ var on a 
form. The user clicks into this var, types, and then I find the match in the 
listBox, highlighting it of course.

I would much prefer doing this by having the user click into the listBox (to 
focus on it) and then just type, with the result of doing the search there. 
Much more natural.

In v17r5, I decided to revisit this to see if it would **finally** work. I 
enabled ‘Before Keystroke’ and ‘After Keystroke’ in the listBox object.
Then in its script, I tried processing these events. However, they do not 
’trigger’ in the listBox. I tried it with the listBox both in ’selection mode: 
single and multiple’.

I understand that there would be no ‘variable’ into which the characters would 
be inserted (as it would be in a comboBox, for example). But I would still like 
to capture and process the keyboard import anyway.

Has anyone been able to achieve this feature?

If not, I would like to put it in as a feature request to 4D.

regards,
Chris Belanger

WP EXPORT VARIABLE does not work Windows Server.

[Luc Devar via 4D_Tech]

4D Server V15.5

I am sending email created in a 4D writes zone that contains images and text. 

wpArea:=WP New([EMAIL_TEMPLATE]TEMPLATE_)
ST SET OPTIONS(wpArea;ST Expressions display mode;ST Values)
WP EXPORT VARIABLE(wpArea;$str;wk mime html)

This worked fine on my Mac ( OSX.13.6), but fail on server (Window Server 
2012r2).  The images are replaced by an interrogation mark ? The rest of the 
email is just fine. 
When I look at the content of the email.  I do not see the image on windows. 

Any idea what is causing this ?

Re: [Tip]Set Query Destination

[Jody Bevan via 4D_Tech]

Doug:

Good practice. I always have the set and reset code within the same method. 
Then when we run our QA method, if one is missing it records the error, and 
places the method with the error description in our listbox to fix.

Good structured coding practices, also makes it much easier to write Quality 
Assurance methods, to ensure the code is correct.

[Tip]Set Query Destination

[Chip Scheide via 4D_Tech]

[Tl;DR] at end

This command is your friend - and - your foe!  :)

Yesterday I spent a significant amount of time trying to track down a 
compiled/built app crash, but did/does not happen interpretedly.

The crash happened only occasionally, after placing alerts and asserts, 
I determined that the crash was happening in a utility method which was 
doing a query. A method which, in the running code, had already been 
called repeatedly - without - issue.
Since the method which was doing the query had been called repeatedly 
-before- the crash, I was perplexed as to what the issue was.
After some more poking and prodding, it appeared that the crashing only 
occurred in the utility method, after a specific method (X) was called. 
Looking at X and watching it execute (interpretedly) provided no 
obvious clue as what the cause was. 
After staring at the code, and running both interpretedly and built 
many more times it finally dawned on me what the issue was...
Set Query Destination

In method X I was doing some work looking for duplicate data, and in so 
doing I was loping over a code that looked like this:
Set Query Destination(Into variable;$Local)
 
Set Query destination(Into current selection)
 
Set Query Destination(Into variable;$Local)

You might see the issue now... 
It turns out I never returned the query destination back to Current 
Selection.
To make the problem even more challenging, the utility method where the 
query was crashing was in a component.

Interpretedly, 4D was happy to create and type the local any time a 
query was executed after query destination was left into a local 
variable but... Needless to say compiled/built 4D DID NOT LIKE 
THAT!  :)

[TL;DR] 
-- always -- reset your query destinations  :)
