Re: Built Server—Best Practices...

[Robert ListMail via 4D_Tech]

Problem solved!  I'd built the server with the latest R3 version while the test 
server was running Hotfix 4. I re-built the server with HF4 and all is right 
with the world.

Re: Built Server—Best Practices...

[Robert ListMail via 4D_Tech]

I know I’ve swapped .4DC files for minor structure updates in the past on 
built-servers; yet, I just swapped out the entire “Server Database” folder in 
the built client and I’m now setting an error that I’ve never seen before. I’m 
sure I could copy over the massive server build and be done with this error but 
I was hoping to better understand why this error came up.

Error: “The database or component “StructureName/4DC” requires the method named 
“SVG_Clear” in the component “4D SVG” to be thread-safe.”

Have you seen that before?

Thanks,

Robert

Re: Form Scaling & Optimal Fonts...

[Robert ListMail via 4D_Tech]

The “Automatic” setting appears to be using Segoe UI 12 as a default. I also 
see “Automatic (Main)” which has a default of 16 point. The sweet spot for this 
Windows interface might be 13 point font; yet, it’s my understanding that any 
font-size over-rides on a particular object drops the dynamic behavior, and key 
benefit, of the automatic style sheet. So, please tell me how you use the 
automatic stylesheet. I didn’t notice originally that there was a “main" and an 
“additional” automatic stylesheets (so 3 in total). In the past I used custom 
stylesheets and never used the automatic. Now, I’d like to understand it better 
so that I can apply this more effectively.

From the manual: "Automatic style sheets manage the font as well as its size 
and color. If you modify one of the properties managed by an automatic style 
sheet in the Form editor, this style sheet no longer works dynamically. 
However, you can apply custom style properties (Bold, Italic or Underline) 
without altering its functioning.”

Thanks,

Robert

Re: Form Scaling & Optimal Fonts...

[Robert ListMail via 4D_Tech]

I showed a scaled up version of a few forms, during a migration to v17 and 
later I decided to move everything to automatic stylesheets as recommended by 
Keisuke that this is best practices now. So, Jefferey, are you using automatic 
stylesheets?  

What determines the font size of automatic style sheets?  In Windows 10, what 
should that size be…?

I have a client that kinda liked the scaled up larger forms…. I moved away from 
that because of the “best practices” suggestions here and because the button 
graphics were also scaled and did not look as sharp. 

This is a screenshot of the current size, it does not look too small to me.

Re: CONVERT PICTURE not seeming to work for me...

[Keisuke Miyako via 4D_Tech]

quicktime is only necessary if you want to convert qti images (v2004 or earlier 
used this format to handle jpeg on windows) you also need to enable quicktime 
with set database parameter.

for pict (quickdraw, not quicktime) you just need 32-bit i.e. altura mac2win

You have to
A be running 32 bit version and
B have QuickTime installed

you could also try the component fro JPR and let that convert for you

CONVERT PICTURE not seeming to work for me...

[Bob Miller via 4D_Tech]

Hi Everyone,

I've recently discovered in my v16 (Windows) database a few rogue records 
that contain PICT images in picture fields.  These, of course, do not 
display in 64 bit 4D, so I need to convert them.

When I run this:

ARRAY TEXT($aPicCodecList;0) 
ARRAY TEXT($aPicCodecNames;0)
PICTURE CODEC LIST($aPicCodecList;$aPicCodecNames)

I see that .jpg is included in the codec list (along iwth png, bmp, gif, 
and others) - but notably, .pict is not there.  Also, if I run 

PICTURE CODEC LIST($aPicCodecList;$aPicCodecNames;*)

to see what codecs can be read, .pict isn't listed, either.  I'm not 
surprised, this is a Windows 10 machine.

When I run:

ARRAY TEXT($aCodecs;0) 
GET PICTURE FORMATS([TextTable]PictureData;$aCodecs)  //` $aCodecs has 1 
element which is .pict

CONVERT PICTURE([TextTable]PictureData;".png")
SAVE RECORD([TextTable])

ARRAY TEXT($aCodecs;0)
GET PICTURE FORMATS([TextTable]PictureData;$aCodecs)  //` $aCodecs has 1 
element which is .pict - so nothing happened!

So nothing is being converted; I start with pict and I end up with pict. 
Maybe this is because I don't have the pict codec on my machine?  (Where 
would I get a pict codec?)  Or could there be another reason?  Thoughts?

Thanks for any advice -

I suppose v17 throws an error because it's less permissive.  
Did you check there is no duplicate names at runtime (FORM GET OBJECTS)?

Re: How to get the current line # in 4D Write Pro

How to get the current line # in 4D Write Pro

Hello,

I used to use the command WR GET CURSOR POSITION in 4D Write.  This would give 
me the current page, column, line# and position of the cursor in my offscreen 
area.  Based on the current line # for example, I could add x number of line 
feeds so that the next section of text would always start on the same line#.  I 
need to do the same thing in 4D Write Pro.  I can’t find any command that will 
tell the the same info.  Any ideas on how to do this in Pro?

Much thanks
