4D server 12.6 as a service on a windows server 2016

[Miguel Gonzalez via 4D_Tech]

Hi All,

Has anyone is running 4D server12.6 as a service on a windows server
2016 machine?

When I start the service it tells me that the start parameter is wrong.
I've never used start parameters before.
Which parameter I need to supply to the service?

Thank you very much in advance.

Re: v17 conundrum in design

[Jim Hays via 4D_Tech]

Chuck,

I've seen some cases where I put a break point in a method that was called
repeatedly.  I would click on the break point to remove it in the debugger,
but it would still stop there.
I solved it by:
- click to remove the break point
- click again, adding it back
- click again to remove it

Odd, but it worked and I didn't feel like figuring out why that happened.

4D Write Pro-Creating Paragraphs

[Mitchell Shiller via 4D_Tech]

Hi,

Banging my head against the wall on this one.
Obviously a simple answer but it seems to be eluding me.

I want to programmatically create a series of paragraphs in WP,
Different paragraphs would have different attributes - e.g. font and margins 
etc.

I cannot find any examples in the KB or in the blog. Documentation seems a bit 
sparse on this.

Any hints?
Are there any example db’s out there?

Thanks

Mitch

While the general consensus is that DIALOG is the way forward, I’ll try this 
for now since it should work with the code as it is.  In more user-oriented 
parts of the system, I am building more dynamic interfaces with subforms and 
such but for a quick “let me search and display data in this table” admin view 
this is convenient and easy.

This works exactly as I wanted. Thanks!

Error 30 When Using HTTP Get or HTTP Request

[4dinug via 4D_Tech]

I am using v17R3 on Windows 10, and attempting to retrieve some 
resources from the web using HTTP Get() and HTTP Request() functions. 
Every attempt fails with an Error 30. Here is the contents of the arrays 
returned by GET LAST ERROR STACK:


*Code*  *Int Comp**
*   *Error description**
*
49
srvr
	SSL internal error : error:14077102:SSL 
routines:SSL23_GET_SERVER_HELLO:unsupported protocol

5
xbox
Access denied {path}
30  4DRT
Error #30

Attempting to retrieve the same resource from a web browser (e.g., 
Chrome) on the same machine is successful, so the problem is in 4D, not 
at the machine level.


Quitting 4D and restarting the database application had no effect.

There's  a thread from November where Bruno LeGay reported the same 
problem, but using v15.5 with  4D running as a service. Keisuke Miyako 
replied, saying something about DNS, but that can't be the issue here, 
since presumably 4D is using the same resolver that my web browser uses. 
Plus the error message returned says nothing about DNS, but rather 
indicates SSL issues as the source of the problem.


Any suggestions would be greatly appreciated.

Thanks.

Document-Management Solution for 4D

[Klaus Droeder via 4D_Tech]

Although I have used 4th Dimension for the last 25 years for my projects,
this is my first post (but hopefully not my last) in this forum.

My company specializes in medical database applications. In addition to
several 4D apps (mostly combined with SQL databases), we have developed a
professional DMS (Document Management System), which I would like to offer
here If you are interested in that kind of stuff read on, otherwise 
The target group for our software, simply called "MacPacs" are 4D
developers, who are looking for a performant and scalable option for saving
lots and lots of documents. Integration into any 4D application is done with
minimal effort, that is to say in less than half a day (seriously!).
If you only have to save a few thousand documents, you certainly do not need
such a software. Most of the time we used it to store medical reports (4D
Write, Word), scanned documents or sonography images. Because sometimes the
customer requirement was to store several million documents, we did not want
to save them either in the database or in the file system.

You can find all the technical details in a compact documentation here
(http://download.macdoc.biz/download.php?file=432). Any feedback or
questions are welcome.

If this (sub-)forum is not the right place for such content, I would like to
apologize in advance.

Thanks

Klaus Dröder

Re: Error 30 When Using HTTP Get or HTTP Request

[Bruno LEGAY via 4D_Tech]

Hi,

Could be there that the SSL/TLS version of your server is not supported (too 
old or too new).

You can use nmap or online tools to check the configuration of the server...

This will give you a list of ciphers

[off] Project Request

[David Ringsmuth via 4D_Tech]

A customer of mine asked me to post this.

He has a project request using 4D’s REST API or Wakanda in front of 4D, 
creating a web-site that can replace an existing web site that is partially 
generated from Active4D.

If you are interested, and familiar with these tools, please contact me.

Thanks!

RE: Error 30 When Using HTTP Get or HTTP Request

[Timothy Penner via 4D_Tech]

I agree with Bruno; the most likely answer is that the server does not support 
TLS 1,2 - use the site Bruno mentioned in order to test the server to see what 
TLS versions it supports.

Check out the blog post from October 2017 describing the change in 4D where we 
no longer allow connections to servers that do not support TLS 1.2:
https://blog.4d.com/more-security-for-your-4d-server/

You can handle this on the 4D Side by lowering the minimum TLS version (shown 
in the tech tip below) but it's not recommended:
https://kb.4d.com/assetid=78102

Honestly, you should ask the provider to update their software so that it 
supports TLS 1.2 as the older algorithms have vulnerabilities in them and you 
shouldn't enable them if you are concerned about security.

-Tim

[off] Project Request

[Tom DeMeo via 4D_Tech]

Hi David,

I've worked extensively with Active4D for over a decade, and also did a 2 year 
full time stint building an app with Wakanda, so I should have the skills your 
client is looking for. 

Let me know if they have any interest in discussing this project.

Re: Error 30 When Using HTTP Get or HTTP Request

[4dinug via 4D_Tech]

Thanks, Tim and Bruno. You are both correct. This particular 
organization's server uses SSL3 and supports only TLS 1.0.


Given that the site in question belongs to one of the five largest 
museums in the world, I would rate my chances at getting them to 
re-deploy their server platform at my request are between zero and nil.


Thanks again.

in case you missed it, the blog link that Tim posted
does explain how you can lower your TLS threshold on the 4D side
with SET DATABASE PARAMETER.
