Re: Pasting tabs into Excel

[Matthias Rebbe via use-livecode]

Hi,

i cannot reproduce that here on Mac OS X and Excel 2016 (V 15.30).
I executed your sample code in the messagebox and was able to paste 
successfully the clipboard to Excel.
I even tried with alpha numeric values.

But what i noticed is the following:
When i just click on a cell, so that it is selected without showing the 
blinking write cursor in the cell, then pasting is working w/o problems.

When i double click a cell, so that it is selected and the blinking write 
cursor is shown, then i cannot paste it correctly.

Tried with LC 8.19RC2 and LC9DP11.

Will try on Windows later this day.


Regards,
Matthias

Re: Pasting tabs into Excel

[Mike Bonner via use-livecode]

It's strange. If you paste into excel, then select the cell and use the
text to columns tool, using Space as delimiter, poof. Columns.  Also, in
libreoffice, paste special can be used to choose "unformatted text" and
that works also.  Surely there is a way to pop a simple tab delimited
string into the clipboard and have it just work..

Pasting tabs into Excel

[J. Landman Gay via use-livecode]

Someone asked me this and I don't have an answer:

Before LC 8, you could put tabbed strings into the clipboard, paste into 
Excel or Google Sheets, and each tabbed item would go into a separate 
cell. After LC 8, the tabbed items go into a single cell as one string.


How can we make Excel recognize the tabs?

For example:

put 1 & 2 & 3 into temp
set the clipboardData["text"] to temp

You may (or may not; it was years ago) need to enclose the command  in
parenthesis, which makes the whole parenthetical a block.  You might also
need to redirect output.

 so

shell ( "(domycommand > myoutput &)"  )

or something like that, and come back later to check myoutput

Re: FormattedHeight of a field and its contents

[David Epstein via use-livecode]

Thanks for the responses on this.  I used Bernd’s tool and did some more tests, 
and found some things that may be helpful to others.

While the left and right margins of a field are meant literally (a 5 pixel left 
margin leaves 5 white pixels to the left of the text), the top margin is more 
complicated, no doubt owing to the variety of textHeights that need to be 
accommodated.  For example, a margin of "0" will often clip the top of the 
text--as if "0" meant a "negative margin".

6 seems to be a magic default value for a field's top margin, which avoids 
clipping the content.  With horizontal gridlines visible, a 6 pixel buffer 
makes the top row the same height as the other rows.  And with a 6 pixel buffer 
the formattedHeight of the field will exactly match the formattedHeight of the 
field's content (although a non-zero borderwidth or a horizontal scrollbar 
changes this).

Thus--what I wondered about in my original post--with a margin less than 6 the 
formattedHeight of the field is less than the formattedHeight of the content; 
the content is in effect clipped.  At smaller textHeights this will be visible, 
while at larger textHeights only white space above the characters is clipped.

I was trying to answer two questions, and I think I'm pretty close.

1. How do I make sure that the field's contents are all visible if I set the 
field's height to the formattedHeight?  Answer: Set the top and bottom margins 
to 6. For the left and right margins, even 1 pixel should be enough to keep 
everything visible.

2. What margins will provide a symmetrical look for a text box?
A top margin of 6 doesn’t look like a 6 pixel margin; how it looks depends on 
the textHeight.  I estimate that its apparent height is one fourth of the 
effective textHeight, and I use this to size the other margins in the 
“tightMargins” handler below.
While the top margin of 6 looks good with horizontal gridlines, without them 
(and especially if you show a text baseline) it looks too small compared to the 
space between subsequent lines.  To match that larger space, in effect doubling 
the apparent top margin, add one third of the effective textHeight.  See 
“niceMargins” handler below.

Example of usage:
set the margins of fld 1 to the niceMargins of fld 1
set the height of fld 1 to the formattedHeight of fld 1

getProp niceMargins
   put the effective textHeight of the target into t
   put round(t*7/12) into m1
   put round(t/3) into m2
   return m1,6+m2,m1,m1
end niceMargins

getProp tightMargins
   put round(.25*the effective textHeight of the target) into m
   return m,6,m,max(6,m)
end tightMargins

Improvements to these are welcomed.

Belay that. Openstack happens first no matter what. I think at this point I 
will use it only as a utility for resizing windows when things have been

Re: RevQueryDatabase error in standalone

[Bob Sneidar via use-livecode]

pCardID contains the long ID of the card that called it. Remember it works 
perfectly in the IDE, so it's doubtful there are any syntactical errors. I am 
vaguely remembering that there are times when openCard is triggered first and 
openstack at other times. If openCard gets triggered first when opening the 
mainstack, none of the libraries (like the utilities backscript containing 
virtually EVERYTHING that makes the stack work) will get loaded. 

A while back I posted there was a difference between Windows and Mac as to when 
certain messages were sent first, but I think now it may actually be a 
difference between IDE and Standalone. 

I will investigate further, now I know where to look.

Correction, I wasn't speaking of 'overhead' as CPU overhead, but as
other things you may need to do as a developer. For example, shell()
nicely runs the app specified and returns any return value, where as
with 'open process' you need to also read from the process to get
returned data, close the process. Any helper app you install that you
call via open process (i.e. some app that is not already part of the OS
or installed software), you really need to code sign (a good practice
anyway) otherwise, assorted 3rd party security tools (mostly on Windows
like McAfee or Norton) are likely to interfere with your launching of
the app via open process by treating it as suspicious activity.

There are probably a few other detail I have forgotten as I wrote this.
We just went through this for a couple of HyperRESEARCH (our app) helper
apps (also LC standalones) that 4.0 of HyperRESEARCH communicates with.

FYI we found that interapp communication via sockets is more reliable
cross-platform that via interprocess communication, but at some real
world customer sites, security setting can prohibit socket communication
even to the same computer where as IPC still works, so an app that need
to be really really robust for real world installs may wish to include
code for both and swap from one to the other if one means of
communication fails.

This is non-blocking:

put tCommandLineUtility && q(tGeneratedFile) into p0
open process p0 for neither -- no need to close that

Don't use quotes for the utility.
You have no feedback with that. That's the advantage of shell.

What additional overhead is incurred by running a process via "open

Re: RevQueryDatabase error in standalone

[Bob Sneidar via use-livecode]

Okay I found the issue with the standalone not building properly. I wrote a new 
handler to size a window based on the min/max left, top,right,bottoms of every 
visible object, so that the "air" or empty space is consistent for every stack 
opened. It *sorta* works, as long as the topmost and leftmost of the most 
extreme top left objects are where you want them to be. But that is neither 
here nor there. 

To do this more easily, I gather the rects of every object, along with a few 
other properties into an array, then convert the array to a memory database, 
where I can query it for the rect,visible and owner properties, excluding 
simple groups (not datagrids) and the menu group. The result is a text variable 
containing these properties of every object on a card that I queried for, and I 
can sort the lines by item 2,3,4 or 5 of each to get the min left and top, and 
the max right and bottom of all the objects. Good so far? 

All that works a peach in development mode. But in a standalone, something 
fails when the app launches AS A STANDALONE. If I open the mainstack in the 
standalone folder in the IDE, it ALSO runs fine, so it isn't that something is 
going wrong in the build process!!! Just not as a STANDALONE! 

Here is the code. After commenting out all the calls to this handler, the 
standalone works fine again. I am completely befuddled by this. If anyone can 
find fault in this code, which would ONLY cause a problem with a standalone, 
I'd love to hear it: 

on setWindowRect pCardID
   lock screen
   put the short name of pCardID into tCardName
   if not there is a card tCardName then return "ERROR: No Card ID supplied."
   put getParentStack(pCardID) into pStackID
   put the left of pStackID into tOldLeft
   put the top of pStackID into tOldTop
   put tOldLeft into item 1 of tOldTopLeft
   put tOldTop into item 2 of tOldTopLeft

Standalone Building

[Bob Sneidar via use-livecode]

Hi all. 

On the issue of Standalone Building with a call to open stacks modally in a 
script, I noted that I can suppress messages and then build the standalone 
without issue. I am wondering if this doesn't cause problems for the standalone 
builder, why not have the standalone builder save the current setting and 
suppress messages before it begins the build brocess, then restore the prior 
setting when it's done?

Bob S

Re: discrepancy between official device metric and LC stack size

[J. Landman Gay via use-livecode]

I test my mobile stacks on a Nexus 5, and, in portrait orientation, many
bottom pixels are offscreen, even though for width and height I follow
exactly the numbers given in dp at the website Device Metrics
 .

Why is it cut off? And how can I avoid this? Is there an LC keyword, like
"effective" or "working", that I should be including if so, how?


Probably the area occupied by the status bar is pushing the stack down. 
Get "the working screenrect" to find out the actual screen dimensions 
your stack can use.


Since every Android device is different, it's usually easier to set the 
fullscreenMode to "showAll" and let the LC engine adjust the size.
