Date entry

[Robert McKeever via 4D_Tech]

4D V15.4, Mac OS 10.13.4

A site that uses 4D Server. Mostly mini’s as clients. Has been working fine for 
years. Then growth, so someone brought in some PC’s. Then they scrounged around 
and now all minis. But, since we are in Canada, sometimes when the OS is loaded 
anew, this select Canadian English keyboard instead of US. So, date entry gets 
set to -MM-DD instead of MM-DD-.

Dates display fine, regardless of format. But, on a couple of machines, you can 
not enter dates. I take my record, place the cursor in the field, and type - it 
moves the cursor along the character string, but nothing changes. So, they just 
go to another machine that ‘works’ and does the entry there. Started a couple 
of weeks ago.

So, why, and how to fix it?

Changing the date format in the system preferences changes the way it is 
displayed, but still no entry.

I hope you continue developing it even if there is something 4D did.

4D won't launch - Windows 10

[David Rose via 4D_Tech]

I have been using 4D v12, 15, 16 on my Windows 10 computer for years, no 
problems until today. When I try to launch any of these programs (4D Developer 
Standard), the 4D window opens with the Help menu visible, the spinning cursor 
appears, but the programs just hang. I have made no changes to my computer in 
the last 48 hours, and I don't believe that Windows has done a system update. 
All other programs on this computer launch with no problems. Here's what I have 
tried, with no success:
* I trashed the AppData/4D folder
* I uninstalled my virus protection software
* I turned off Windows Firewall
* I moved the Licenses folder to the desktop (just to see if I could launch any 
of the programs in Demo mode.)
* I checked the Windows DEP setting and confirmed that it is set to apply only 
to Windows essential programs and services.
* I rebooted the computer
* I downloaded and installed a fresh version of one of the 4D programs - it 
won't launch.

I have lots of RAM and hard drive space.

Any other ideas anyone?
David

4D Write Pro using 4D Write-Like Toolbar

[JOHN BAUGHMAN via 4D_Tech]

I finally got  this resolved with some help from tech support.

FYI, if you are having trouble getting 4D Write Pro to work in an old database 
form, try replacing the form with a newly created one.

In my case the form was an input form that was probably created in v6 (2003). 
The main issue was that 4D was not recognizing the initialized 4D WRite Pro 
variable as a 4D Write Pro Object. Replacing the existing input form with a 
newly created from fixed the problem. I just copied everything from the not 
working form to the new form and it worked.

 See my original post below for.a more detailed description of the problems I 
ran into.

For the record, ObjectTools itself might be not leaking, rather there might 
have been places in your code where you didn’t clear an object when finished 
with it.

Having said that, using C_OBJECT is of course preferable because you never have 
to worry about memory leaks. I wrote ObjectTools in 1991. It only took 4D 25 
years to implement the equivalent.  :-)

Re: How does one detect that Cookies are disabled?

[Jim Labos - infobase via 4D_Tech]

Hi John,

I just saw this and will check it out. I knew there are Javascripts to check
for Cookies but was resisting going that route. I will give it a try.

Thanks to you and Danny Beaubien.

Cheers

Have you tested with creating a new database instead of opening an existing

4D "metrics?"

[David Eddy via 4D_Tech]

Folks -

At the 4D Summit in 2001 in Orlando, someone—Lincoln Stoller?  Paul 
Carnine?—presented a metrics utility.

Anyone have documentation from that?  Or remember who it was?
