Re: How does one detect that Cookies are disabled?
First of in my testing I am not involving 4D at all. I was simply using Xojo to test what you said in your post. After a bit more testing, I realize now that I misunderstood your post entirely. > I don't know anything about Xojo, but from the code you posted all it seems > to do is set a value on the server and immediately read it back. There is no > way for the browser to have it yet. The code I quoted is Xojo code (not 4D) and it sets the cookie in the browser from a Xojo web app. With Chrome’s developer’s console I can watch the cookie being set when cookies are not being blocked. What I should have understood in your post was that any web app or web server can only determine if a cookie is set by what is passed from the browser in the http header. So if my Xojo web app sets a cookie in the browser, that would not be reflected in the header until the header was updated, which would only happen the next time an exchange occurred between the web app or web server and the browser. Xojo is adding the cookies it set since receiving the current header to my test. For my idea to work in Xojo or 4D Web Server, there would have to be a way to refresh the http header without refreshing the whole browser window. Perhaps not possible.??. I noticed that eventually the header is updated after the user has invoked a request or 2 to 4D (4d Web Server only talks to the Xojo web app not the browser). Not sure when or what causes the header update during those exchanges.

Re: How does one detect that Cookies are disabled?
I don't know anything about Xojo, but from the code you posted all it seems to do is set a value on the server and immediately read it back. There is no way for the browser to have it yet. The browser only sets a local cookie from a HTTP response containing a "Set-Cookie" header. If cookies are enabled, the *next* request to the same server (with conditions related to the url) will have a "Cookie" header with the value from the previous request. If you wanted to do this in what *appears* to be a single page request, your initial request to the server could return some Javascript that immediately calls back to the server with the cookie value (or reports it not found). Of course, via Javascript, you could also check for the cookie and complain to the user directly that cookies are off without ever reporting the status back to the server.

Re: How does one detect that Cookies are disabled?
Thanks John. This was my finding as well although I was not using Xojo (if Xojo code is running from within the HTML form than if it programmed to send message to server you may be able to detect it). Essentially the browser does not see anything until 4D ends the code. I have not checked if it does work right after the WEB Send Blob or WEB Send File but before Web Process ends execution.

Re: Flexible SVG ID Strategy
SVG is XML, so you can have as many namespaces as you like. in all of my SVG editors I define a private namespace, which contains extended information such as group ID. it also helps to store transform values (rotate, scale, translate) as individual attributes in said namespace, so much easier than to extract via regex or whatever each time. https://github.com/miyako/4d-widget-svg-area-v3 https://github.com/miyako/4d-widget-svg-area-v2 > 2018/06/06 5:22、John J Foster via 4D_Tech <4d_tech@lists.4d.com> のメール： > So wondering if anyone has decided on a strategy for managing SVG OD’s and > how to best handle moving things around? ** 4D Internet Users Group (4D iNUG) FAQ: http://lists.4d.com/faqnug.html Archive: http://lists.4d.com/archives.html Options: https://lists.4d.com/mailman/options/4d_tech Unsub: mailto:4d_tech-unsubscr...@lists.4d.com **
4D Write Pro using 4D Write-Like Toolbar
I am struggling trying to get the 4D Write-Like Toolbar to work…
http://download.4d.com/4DBlog/Tips/4DWriteLikeToolbarDemo.zip
I am trying to create a transition from 4D Write to 4D Write Pro so I have
added a second page to the input from and moved the 4D Write area to the this
new second page. On the first page I have put the 4D Write Pro area and the
Write-Like sub form. To make it simple I have named the 4D Write Pro the same
name used in the Write-Like Demo... WP_WriteProArea
I am working in my templates table. When an existing template record is opened,
in the on load event of the input form, I am initializing …
C_OBJECT(WP_Information;WP_WriteProArea)
WP_WriteProArea:=WP New("")
WP_Information:=New object("IsNewDocument";True)
WP_Information.DocumentInfo:=New
object("FilePath";"";"Modification";False)
FORM GOTO PAGE(2)
In the demo all of the above is done before the form is opened. When the form
is opened in the On Load phase of the main window, the window title is set as
is the focus set to the 4D Write Pro area. Nothing more in the main window.
That leaves the sub form On load event. Just to make sure that the subform is
working, I would normally to to page 2, but I am leaving the user on page 1 and
have confirmed that all of the On Load code has run in the subform. At this
point the 4D Write Pro area is blank, exactly like it is in the Demo.
The problem is that unlike the demo, nearly all of the menu items in the
subform are disabled.
The load document icon works, so I loaded a wp4 document from disk. That
worked. If I select some text, then select a font from the font popup list, 4D
throws an error on this line…
$wpRange:=WP Get selection(WP_WriteProArea) //“form object not found
or form object is not a 4D Write Pro Form Object"
This is in the method GetSelectionInfo which I have not touched.
The only difference that I can see between what I have done and what is in the
demo is that I have ca;lled WP_WriteProArea:=WP New("") in the on load phase of
the input form and the demo calls it before the form is opened. I hope that is
not the problem.
Any help would be greatly appreciated.

Re: High Sierra - Export Text in 4D v13.6

Re: How does one detect that Cookies are disabled?
John DeSol just pointed out that my idea would not work.. I just did some
testing to see what John was talking about.
Using Firefox and Xojo I ran the following test with cookies enabled…
session.Cookies.Set("testing","test")
if Session.Cookies.Value("testing") = "test" then
MsgBox "Cookies are NOT disabled: "+Session.Cookies.Value("testing")
else
MsgBox "Cookies are MAY BE disabled: "+Session.Cookies.Value("testing")
end if
As expected it reported that cookies were NOT disabled. Watching cookies in the
Web Developer Storage tab in Firefox. however, I could not see the cookie until
I refreshed the browser.
Then I ran the same thing with cookies disabled and surprisingly I got that
cookies were still NOT disabled. In the storage tab as before I could not see
the cookie, only this time when I refreshed the browser, I still did not see
the cookie.
After a bit of more testing, I have concluded that as John stated cookies are
not in fact set until the browser receives a request subsequent to the one that
sets the cookie.
I will be exploring further why Xojo is seeing the cookie when in fact it has
not been set. I suspect that it is not really reading the cookie from the
browser but instead storing the cookie value for the duration of the current
request. Perhaps it has to, since it really cannot be read from the browser yet.
In any event, I do not think that testing for a test cookie is going to work.
At least it will not work using a Xojo web app.

Re: Flexible SVG ID Strategy
The easiest way I've found to move the objects in a group is to
SVG_SET_TRANSFORM_TRANSLATE the group when the mouse is moving.
Later if you UNGROUP, the translation needs to be spread out over the group's
children so they don't jump to new locations.
You can use SVG_Get_root_reference in a loop to find the topmost group of the
clicked object (the last one whose TYPE is not "svg").
Unless an ID needs to be meaningful, I've been letting the 4D SVG Engine set
the ID (SVG_SET_OPTIONS), or setting the ID to GENERATE UUID.

High Sierra - Export Text in 4D v13.6
Came across a weird behavior and want to know if anyone else has encountered this and how to solve this (mac & V13.6 & v15) I use a document (“StoreHere.txt") in the Resources folder to store some data in it, to be used later. After using the command Export Text, the document is ‘updated’ allright BUT there is a .temp file with a long filename (“07B29AA87F90481387491D4EEF206BB6.temp”) ALSO created in that Resource folder. But this is not wanted because every time the export is performed a new file with long name is created !! It does this ONLY with High Sierra (10.13.4), none of the previous mac os X has this (I tested this). (fyi: 4D v15 & up do not exhibit this behavior with os 10.13.4 ) Have a test db V13.6 with 1 table and 1 or 2 fields (doesn’t matter how many) and 2 or more records. I use one LongInt and one Text field. then make a method that I can call using a button on the layout. this is the method: C_TEXT($sDocName) $sDocName:=Get 4D folder(Current Resources folder)+"StoreHere.txt” ALL RECORDS([Table_1]) ORDER BY([Table_1];[Table_1]seqNo;>) FORM SET OUTPUT([Table_1];"export") EXPORT TEXT([Table_1];$sDocName) FORM SET OUTPUT([Table_1];"output") Any input on this is very welcome.

SVG Area and sizing monitor issues
Hi All,
{I sent this yesterday & and again earlier today and it never made it through?}
Another issue that is becoming a challenge is managing for monitors that can be
retina or not or large screens or not.
I am currently studying the best way to manage this. I am starting with
allowing the user to set a portrait or landscape size for the 4D SVG area they
will manage within. The user will be able to drag and drop objects onto the
area and move them to specific coordinates. This will be saved as a template
and be able to be reused.
The SVG area on the screen will map to a portrait or landscape form that will
print. (that seems like the easier part).
My current work environment is to plug my Retina MacBook Pro 15” into a BENQ
PD3200Q 32” 3840x2160 4K. I can work in a very large area on this monitor (very
easy on the eyes) and about half or less when it goes back to my MacBook Pro.
And of course then I have to concern myself with laptops and other monitors my
users will work off of windows and Macs.
With an SVG area there are several possibilities. One of them is to scale the
size of the image to scale with the monitor dimensions. Not sure if I like it
(rather manually zoom in/out) but I’ll likely test it as an option. Or I could
define the SVG work area (portrait/landscape) and adjust size but maintain the
same dimensions. Seems like a better option. And who knows at this point …
So is anyone dealing with this issue? How have you managed it? What do your
users prefer?
BTW I am running in 4D v16 r6 and will be moving to v17. It is a standalone
cross platform application.
Appreciate,
John…

Flexible SVG ID Strategy
Hi All,
{I sent this yesterday & and again earlier today and it never made it through?}
I am trying to create an interface built using SVG. The sag image will include
many different kinds of complex objects. Bu complex I mean that each object is
itself a complex object built by SVG and added into the main SVG image.
I want to be able to identify any part of an image I click on even if it’s part
of a group. But I also want to be able to move the object around to different
coords in the image.
I am using SVG_SET_ID (domSvg;”id_name...”) set each part of the objects ID.
when I click on them I see the ID and this works great. BUT...
But when I move an object I want the entire object to move not just the part of
it.
So wondering if anyone has decided on a strategy for managing SVG OD’s and how
to best handle moving things around?
If this doesn’t make sense please ask questions.
BTW I am running in 4D v16 r6 and will be moving to v17.
Appreciate,
John…

Re: How does one detect that Cookies are disabled?
Not know what you are using to set and read cookies I really do no have an answer for you With whatever you are using, can you… Set Cookie: “test=Test" testCookie := Read Cookie “test” If testCookie = “Test” Then Remove Cookie: “test” // cookies are not disabled Else //cookies are probably disabled, alert the user End If John > On Jun 5, 2018, at 7:28 AM, Jim Labos - infobase via 4D_Tech > <4d_tech@lists.4d.com> wrote: > > So I cannot assume that the Cookie was created because of not being able to > read it on same connection, and I cannot assume it wasn't created due to > Cookies being disabled. ** 4D Internet Users Group (4D iNUG) FAQ: http://lists.4d.com/faqnug.html Archive: http://lists.4d.com/archives.html Options: https://lists.4d.com/mailman/options/4d_tech Unsub: mailto:4d_tech-unsubscr...@lists.4d.com **
Re: How does one detect that Cookies are disabled?
Yes but I am trying to detect if Cookies are "Disabled". If I can read the Cookie it exists and there is no problem. If I cannot read a Cookie then I will create it and that is where the problem lies as one cannot know if it was or not. At least not immediately. That is the predicament.

Re: How does one detect that Cookies are disabled?
I am creating the cookie and immediately after that checking if cookie exists. We handle our own session so no we do not use 4D Session method. So by session I mean the initial call on the server. Using v13 in this application. 1: User hits server with a URL. 2: Server analyzes URL and if it passes checks for presence of cookie. If Cookie does not exist we create it. So at this point if the Cookie gets created all is fine but if user's browser has Cookies disabled 4D does not get an error or any indication of that. If I try and read Cookie on same connection/session the Cookie can indeed exist but it will come back as blank value. If Cookie had previously existed then there is no need to check of course. We only want to check when we create the Cookie. I think that it's a question of the Browser not actually creating the Cookie until 4D ends the connection/method. If one traces the browser's actions one only sees the Cookie existing only after 4D sends the response but not before that. Upon the next connection there is no problem reading the Cookie. So I cannot assume that the Cookie was created because of not being able to read it on same connection, and I cannot assume it wasn't created due to Cookies being disabled.

Re: How does one detect that Cookies are disabled?
you may never be able to detect such a cookie on this configuration.

Re: How does one detect that Cookies are disabled?
Jim, Hard to help here without some additional information. By "session" do you mean you are using 4D's automatic session management? What version? You might also show a bit of your code. So you are sending your first response with a "Set-Cookie" header and the *next* request from the browser does not have the value in the "Cookie" header?

Re: OK to Create V12 Built Server for OS X on OS X 10.13
Hey Doug, I don't have much to offer but thought I'd chime in at least. We haven't deployed v12.6 server on Mac for a while, but we do have some _clients_ running v12.6 on macOS. One user in our office runs on macOS 10.12 everyday - generally works OK. However, for development we found that v12.6 (client) was crashing a lot, so we just don't do it on our new Macs. And we typically do a new build for Mac about once every 3 years. Happily moved on to 16R6.

Re: How does one detect that Cookies are disabled?
Hi, Don't take this the wrong way but other then telling me what you do on your computer to the cache from browser I don't know what this has to do with the subject matter. I just want to be able to "detect" if cookies are enabled or not. It is not my business what the person connecting to the server why or what he does. I just need to know so I can re-act accordingly. The connection is not with a website but it is to surveys that are mandated by the organization they belong to. So it is in no way an attempt to intrude into their browser history if that is what you are implying. Being able to detect that cookies are disabled can allow us to alert them that they will not be able to participate. It then becomes their choice.

Re: How does one detect that Cookies are disabled?
regardless of what other info you get back there is one more thing to consider... People like me :) I go into the (on Mac) Library folder and locate cookie, history, cache, and other web related directories. I empty them, the lock them, i.e. the soft are can NOT write into that/those directories. This stops persistent cookies etc from functioning. Stops web sites from downloading "stuff". Once the browser has been exited, there is nothing left from previous web sessions. All of this is in addition to ad blockers, and often indirection through TOR.
