structure file=(structure file(*))

its even in the documentation

http://doc.4d.com/4Dv16R4/4D/16-R4/Structure-file.301-3317749.en.html

a notable exception is PROCESS 4D TAGS (apart from plugins)
which is evaluated in the host context even when used in a component
(it's the only way I know to directly access process variables of the host from 
a component)

Re: Base 64 broken in 4DIC 16.x?

[James Bareman via 4D_Tech]

Hi Jeffrey,
I am seeing this as well with build 16R4.216142.
From my testing, it seems that when you specify the default encoding with
SMTP_SetPrefs and with SMTP_Charset(0,0), whatever you pass as the email
body actually gets Base64 encoded. So, if you were already encoding your
message body before adding it with SMTP_Body, what ends up being sent is
doubly encoded.

Obviously I misspoke about the BAT file, you can directly call the cmd.exe

If you only work on Windows (like me) you can take advantage of a Windows DOS 
command by creating a batch file with the following:

 SET ENVIRONMENT VARIABLE("_4D_OPTION_HIDE_CONSOLE";"TRUE")
 LAUNCH EXTERNAL PROCESS("cmd.exe /C rename "+$dir_current+" "+$dir_rename)

You just need to account for any spaces in the path names, since they will need 
to be placed inside double quotes.

Very simply, very fast...

Re: v13 - Renaming a Directory via code.

[Chip Scheide via 4D_Tech]

Thanks Tim,


I wrote code to use MOVE DOCUMENT and CREATE FOLDER to do this.
It works, it is (on my tests, NOT very deep folder structures) quick.

So - Folder_Rename(Old_Folder_Path;New_Folder_Name)
works, no problem.

Then I tried to change the case, rather then rename on a folder and hit 
a wall...
Folder_Rename(Old_Folder_Path;OLD_FOLDER_NAME)

FAIL!
folder already exists of course it does!!! as the OS is case blind, 
unless you are one of the few masochists out there running OSX with 
case sensitivity turned on.

this is where I stopped today...

I will try your code, I suspect that it will work even with a case 
change, as this is occurring at the OS level, rather then 4D.

Thanks again

It is an excessive amount of work. We need a native RENAME FOLDER command or a 
MOVE FOLDER command. I don’t think it makes sense to make the MOVE DOCUMENT 
command also work with folders. It needs to be a separate command.

So I had to write my own RenameFolder command. Here it is Chip:

C_TEXT($destinationFolderPath_t;$command_t;$inputStream_t;$outputStream_t)

$destinationFolderPath_t:=GetParentDirectoryPath

4D Write Pro and SMTP_Body

[Piotr Chabot Stadhouders via 4D_Tech]

Hi,

We use 4D to send HTML emails
Until now we used 4D Write to generate the mail body, and convert it to HTML 
(WR SAVE DOCUMENT ($area;$docpath;wr HTML 4 document))

Now we want to convert this to 4D Write Pro.
In WP there is a command WP EXPORT VARIABLE to convert an area to HTML ("wk 
mime html" or "wk web page html 4D")
Because we don't use SMTP_QuickSend but SMTP_Send with SMTP_Body, we cannot use 
"wk mime html" but have to use "wk web page html 4D"

My questions :

  *   Am I right that we can't use use "wk mime html" but have to use "wk web 
page html 4D"?
  *   Is it true that the use of bullets in HTML is not supported when sending 
by email?

Thanks,

Piotr

Selecting tables in a Write Pro Area

[Piotr Chabot Stadhouders via 4D_Tech]

Hi,

I am experimenting with 4D Write Pro.
Because WP only supports inline pictures I thought to give tables a try, i.e to 
insert a picture in a cell and text in a next cell (what is a "workaround" for 
wrapping text around a picture)

Inserting a table with some cells is no problem, but I have no idea how to 
select a table in an area by programming.
Even more, I find selecting other objects, like pictures, not intuitive as well

Does anybody know how to select a table in an WP area by programming?

Thanks,

Piotr

Re: Ergonomic 4D office...

[Roger Reed – Illus House via 4D_Tech]

I used those “kneeling” chairs for many years, in which some of the weight is 
shifted from your butt to your knees. They’re also backless, and that’s the 
problem — no back support. I ended up hunched over all the time. [And couldn’t 
put any papers on my chair.]

So I got an Aeron chair and it has suited me well for several years. Don’t get 
a foam-y substitute. Recently I elevated my computer so it’s truly at eye 
height. That forces me not to hunch over and it works very well for that.

The third factor is the mouse position. At desk height I found I was raising my 
shoulder all day with painful results. Lowering the mouse down to roughly lap 
level made a huge difference for me.

Feature request : new command : MOVE FOLDER

[Chip Scheide via 4D_Tech]

link to forum request:
http://forums.4d.com/Post//21269476/1/

text of request:
>Product :4D - 4D Server

The command MOVE DOCUMENT chokes (v13, also reported in v11 and v12), 
on trying to move/rename a folder.

According to comments in the original feature request (for v11) MOVE 
DOCUMENT would rename/move a folder, in versions of 4D v2004 and 
before..

We need to have either : 
- MOVE FOLDER, a new command (which would function as Move Document, 
but with Folders)
or
- MOVE DOCUMENT, needs to be fixed to work with folders, as it did in 
v2004 and before.

Though it's pricey, I opted for a chair from Relax the Back
.
It's very adjustable and it has allowed me sit conformably for hours on
end, even with two hips that were, thanks to my then-significant
mass, rapidly deteriorating.

Until a few years ago, I had been using a desk that was custom built a long
time (as in 4D version 2.2). It was a simple design with a 6' desktop, a
modesty panel, and two drawers. The key was that it was made of oak veneer
plywood so it was quite affordable.

My choice this time around was an an adjustable desk

which
allowed me to reduce the pain from my hips. I don't raise/lower it much
these days but I can adjust the desk height to within 0.1" so it's
extremely comfortable.

On the topic of "feed your head", I use gear from Hsu, Schiit, Sennheiser,
Etymotic, Grado, and HiFiMan but that's a *much* longer discussion.

Re: Combine pictures in v15

[Ronnie Teo via 4D_Tech]

Hi,

Your 4D tech-note helped tremendously.  The Transparency transformation was 
exactly what I needed.

I could have sworn I went through the picture commands but somehow missed that….
Thanks again.

Re: Working 4Dv15 Windows

[Ronnie Teo via 4D_Tech]

Hi,

Thanks for your reply, managed to resolve the issue following advice from Armin 
Deeg.

I did the following :

• Change the font for the method editor
• Deleted the 4D folder files inside c:\users\USERNAME\Appdata\Roaming\4D\4D 
Preferencesv15.4dpreferences and 4D Window Bounds v15 

The System font along with some other fonts played havoc with the text display 
in the Method editor.

Regards,
Ronnie

v13 - Renaming a Directory via code.

[Chip Scheide via 4D_Tech]

I want to rename a directory, from say New Folder -> New Folder too
Move Document complains, as neither the source nor the destination are 
documents.

is there another means to rename a folder other than:

- Create new folder with new/changed name
- copy all contents from source folder to destination
- delete original

-repeat for all sub directories of the original source)

seems like an excessive amount of work for a change to a directory 
name.

RE: Working 4Dv15 Windows

[Jim Medlen via 4D_Tech]

We had an issue upgrading from v13 to v15 with the MESSAGE command not
displaying text on Windows clients.

We submitted a bug report and were told it would be fixed in future
versions of 4D.

The resolution was to wrap methods using the MESSAGE command with

SET DATABASE PARAMETER(Direct2D Status;Direct2D Software)  // Enable
Direct2D fixes message bug with Windows client

// previous code or method

SET DATABASE PARAMETER(Direct2D status;Direct2D Hardware)


We were told the issue had to do with the removal of Direct 2D support

I edit and compile using a Mac so I do not know if it effected the Editor.

Components and subforms

[Jim Dorrance via 4D_Tech]

I have component in a subform included on a form in the host database. Is
there a simple way to discover in what context (host DB or component) a
particular method (host DB method or component method) is being executed
when I execute a method on a Call Subform Container call event?

Thanks

Re: Is a package preferred?

[Keith Culotta via 4D_Tech]

I switched back to folders for development.  It's easier to manipulate the 
app's supporting folders and files.  Users get a package, but like Chip said, 
you have to guard against the unintentional use of the datafile within the 
package.

Re: Is a package preferred?

[Chip Scheide via 4D_Tech]

Other issue with package systems:
- data file can be unintentionally replaced/lost during an update to the 
structure/package.
ex: client copies new structure/package to old location overwriting existing 
structure/package -- datafile (other items(?)) LOST!

I understand the idea - but I always move the datafile others the structure 
package

Re: Server Process "Frozen"-ish

[Keith White via 4D_Tech]

Hi

OK, so we think this is due to DELAY PROCESS.

The change to DELAY PROCESS somewhere in 4D v15 was to change from a Longint to 
Real.  But the problems didn't start until v16, I think that's right.

Anyway, I'm wondering if the problem is when either Tickcount, Milliseconds or 
another internal 4D time measure overflows into negative territory.  I have no 
idea internally what measure 4D uses for DELAY PROCESS, nor what data type they 
use internally for it, but what if they aren't taking account of the overflow 
when the measure value goes from a large positive number to a large negative.

That could explain the large time period before the problem reoccurs??

Just throwing an idea out there.  We've only just jumped from v13 to v16R4, 
which means we don't have v16 out in production land yet, so we haven't yet 
seen this problem occur.

Best regards

4D server knows, but a client has to ask, due to other clients inserts or 
deletions. If any client had to be aware at any time, we would have a huge 
traffic. 4D could embed these value in some "stowaway", as I described, but 
it's not the case.
