SHA-2 Certs and 4D v13.5

Hi

Just wanted to check that you can use SHA-2 (ie 256 bit) type SSL Certs with 4D v13.5 Web Server.

I presume you can, but thought I'd better ask.

Best regards

Re: 4D via Terminal Services Intermittently Sluggish

Hi Jim & Julio,

Ref: "How about having the user ping the server from his location."

Yes, that's a possibility.

Ref: "Can you teamview/join.me/vnc into the user's machine when he experiences slowdowns and then check
the quality of his connection?

If it is a local issue, you will not be able to track it for anywhere else..."

Yea, I'm sure something can be setup. Makes sense.

What I've decided on is to log from his computer every minute as he's using the system. I've created a method,
with Execute on Server property set, which is called from within a polling routine, launched when the user
logs in. It will just return the system date and I'll record the time it takes to it. Store in a database
record so I can view them as they occur.

I need to see if it's a 4D thing or a TS thing. So trying to eliminate potential issues.

Thanks for your feedback.

Appreciate,
John...

4D via Terminal Services Intermittently Sluggish

Hi All,

We have a 4D v13 windows based server. We have both internal users in our office and remote access from around
the US. Most remote in to 4D direct without issue. In another case we had to provide access to 4D via Terminal
Services (Remote TS) as straight 4D remote was way too slow. If I recall correctly he's connecting via a
windows computer. Not sure of OS.  Anyway, usually it works great!

BUT...

Occasionally, like the last couple of days, intermittently, the Remote TS connection becomes quite
sluggish. Click a button and wait for seemingly minutes. That kind of thing. Also heard the same thing for
at least another remote Mac user.

Of course when we - IT guy and I - check, everything seems to be in perfect order. When we call the user and do a
local speed test for his internet connection it's quite speedy.

So I am wondering how I can best track this issue down. Is there something I can do on his computer, our
computers, that will help me diagnose it?

Maybe writing a method that periodically test his connection speed by sending something to 4D and seeing
how long it takes to come back. That will only tell me that there's an issue though. Not sure.

Any ideas? Code examples?

Appreciate all help,
John...

Re: DOM EXPORT TO VAR change from v12 to v13

Hi,

yes, it is the UTF-8 BOM…

You need to delete these bytes to produce identical results from v12 (xml without bom).

C_STRING(32;$va_domRef)
$va_domRef:=DOM Create XML Ref("test")
If (ok=1)
C_BLOB($vx_blob)
SET BLOB SIZE($vx_xmlBlob;0)

DOM EXPORT TO VAR($va_domRef;$vx_xmlBlob)

XML_blobEraseBom (->$vx_xmlBlob)

DOM CLOSE XML($va_domRef)
End if

Getting Started with oAuth plugin on v13

Hello,

i am working in a 4Dv13 setup and in need for zip/unzip and md5 functions.
I found miyakos plugin '4d-plugin-oauth' on github.

https://github.com/miyako/4d-plugin-oauth

4d.com lists this plugin as well under: http://sources.4d.com/trac/4d_keisuke/wiki/Plugins/ZIP
This page is referencing v12.

Now i am wondering: 
a) Is the plugin supposed to work with v13 as well? 
b) How to add this plugin to my project?
I tried putting the .4dbase file to my plugin/component folder without success.

Any help is highly appreciated

Best Regards
Florian

DOM EXPORT TO VAR change from v12 to v13

Short Story: in V13,
DOM EXPORT TO VAR (XmlRef;Blob)
... Inserts 3 bytes of data before the opening < tag.

Try this in V12 vs V13

<---------BEGIN------>
$Ref:=DOM Create XML Ref("test")
SET BLOB SIZE($data_x;0)
DOM EXPORT TO VAR($Ref;$Data_x)

`V13 Results
$Pos_0_i:=$Data_x{0}  //239
$Pos_1_i:=$Data_x{1}  //187
$Pos_2_i:=$Data_x{2}  //191
$Pos_3_i:=$Data_x{3}  //60  <

`V12 Results
$Pos_0_i:=$Data_x{0}  //60  <
<---------END------>

I'm curious why that is.  Created a bug in at least one of my systems.

DB4D.DLL

We have had a crash on a windows server (4D v13.4 64bit) in the DB4D.DLL with a null pointer reference. The
windows OS is Windows Server 2008 Enterprise Edition. The computer has 64 GB memory, 4D has 20 GB cache.

Has anyone encountered such a problem? This is the first time that I have seen it.

Scroll bar Missing in Debugger

I am getting frustrated with this. When I put a break point and look to
examine the code - I am not able to view beyond line 40 or so. There is no
scroll bar!

This is 4D v13.4 on Windows.

Use FORM SCREENSHOT inside an error hander?

Is Current form name really defined everywhere in a process?

Put another way, is something about the "context" of a process different
when I'm inside my ON ERROR handler code, so that Current form name isn't
as useful as hoped?

In particular, does it mean that if the current form is temporarily
undefined, I can't capture the screen image for the form?

The code is like this:

*C_TEXT*(form_name_t)

*C_PICTURE*(Screen_Capture_Image_x)

form_name_t:=*Current form name*

*FORM SCREENSHOT*(Screen_Capture_Image_x)

The code works like I expect if I just run a test; I end up with a useful
picture. So my screenshots for documentation and for user-initiated
communication will be fine.

However, the same code inside the error handler results in null string for
the form name and a zero byte image.

Any thoughts, ideas?

Is it possible to Un-Delete a table

Hey All,

This is mostly an academic question - meaning I am not currently in trouble.

Here is the scenario. Let's say, through a mistake, a table is deleted from
my structure.

Is there away to re-create it so that when I send an updated structure to
my clients that they don't lose the data from the table?

Would the .match file be involved in this?
