In a v15.6 client/server application for Windows, I have a license for 4D Write
attached to the 4D Server license.
I just moved all of the 4D server components to a new machine, including the
licenses. They are definitely in the right Licenses folder.
When I launch 4D Server and go to Update Lice
Are you sure you moved plug ins and not alias/shortcuts to them
You are always better off re-licensing as opposed to moving. If you ever
need to uphgrade number of clients, I think you will need to re-license
then.
I would also try re-license

In a multi-process 4D, less then version v16, environment (not
multi-threaded),
4D stand alone (single user) or C/S (client side),

a process var (x) is set to value "A"
- In process 2 the component i
Each component has it’s own namespace for it’s variables. They behave exactly
as they would as per 4D Rules. Interprocess vars have a scope across all
processes, process vars only have scope with the specific process.
So in your example, that process var in process 1 would be “A” and in process
Further you need to use pointers into the compnent to get value. That is a

In host db you have a variable named Version_txt which is set to “10.5 4D
version x.x”
You can have a variable named Version_txt in the component with a different

IP vars inside a component does that make any reference to the
component code (or at least methods that use/reference the IPVars) NOT
thread safe? or is the component 'walled off' for this consideration?

IP vars are not thread safe, so the component method could not be marked as

How about?
- Using the TS syntax as described here:

- Using CAST to cast the TEXT as a Timestamp:

Tim,
Thanks...
I already tried using CAST, but that made no difference. I'll check out the
other link, and revisit the CAST link.

I tried the following with no success:

There may be multiple things wrong here;
First, is your field actually named TimeStamp?
If so, this is a SQL Reserved word and shouldn’t be used as a field identifier.
Let's start with that first.

Tim,
This is a MS SQL server database and it queries just fine using a static
timestamp value, as shown below:
Begin SQL
SELECT RecordID, Mach_ID, Energy_1, Energy_2, Energy_3
FROM DMM_TTX_HISTORIAN
WHERE TimeStamp >= '04/06/2018 07:58:00 AM'
AND TimeStamp <= '04/06/2018 09:0
figured as much...
Thanks

Hi Steve,
First can you do a sql call and add timestamp to return. Use cast as VARCHAR
Begin SQL
SELECT RecordID, Mach_ID, Energy_1, Energy_2, Energy_3, TimeStamp
FROM DMM_TTX_HISTORIAN
WHERE cast(TimeStamp as VARCHAR) >= '04/06/2018 07:58:00 AM'

Try removing the single quotes in your text variable assignment and retry your
initial example.

That looks like the field is just plain text; have you tried just removing the
extra single quotes from the text variable in your initial example (Justin Will
also suggested this)?

I've done that multiple times and nada. The error being returned by the driver
is that it says you can't convert an "ntext" to "timestamp":

Tim,
See my response to Justin, I simply get an error back:
Error Desc = Error #206 (Operand type clash: ntext is incompatible with
datetim)
How the heck do we query a timestamp field dynamically, this just seems much
more difficult than it should be.

Tim & Anyone Else,
I got it working using the following:

I love the concept of tables in 4D Write Pro.
You can only add or change them by code, which is fine by me for the moment.
But what to do if a table has been created, and, in the 4D Write Pro document,
you would want to add a column, or a row? Or change the width, the borders etc?

You don't need to use sets.
Follow Keith's scheme, but without using 4D objects (which were not available
until v14.)

The 510 bytes data does not contain anything useful for you.
