Re: 4D V15 crash

[John DeSoi via 4D_Tech]

Look at the crash log (should be in ~/Library/Logs/DiagnosticReports). It often 
gives helpful clues about what is causing the crash.

4D V15 crash - further info

So, I set the compiled/merged app up here. Runs fine. I even downloaded the 
merged app from our FTP in case a new plug-in might be bothering it.

No such luck.

4D V15 crash

[Robert McKeever via 4D_Tech]

My client (4 time zones away), had been running the single user compiled and 
merged app under windows. Then he purchased a new Mac. It is running 10.14.3, 
I’m running 10.14.4. I have moved the appropriate mac app files to his machine, 
along with the datafile and index file from his PC.

4D crashes on startup.

Then I had him add a printer. Tried again. No  luck.

Any ideas?

Re: Re(2): Window reverse layering issues

if the user clicks on it to bring it forward it has to have received 
the click, and it should generate either or both outside call, activate.

Re(2): Window reverse layering issues

[Don Lapin via 4D_Tech]

Hi Chip,

Does the incorrectly-layered window (the type 8 in this case, supposed to be in 
back of the modal) receive events? I haven't tried that yet.

Thanks,
Don

Re: 4D 17.1 network issues

[John DeSoi via 4D_Tech]

I set the WiFi to "Inactive" using the small popup at the bottom of the list 
and rebooted the computer. That removed it from the ifconfig list and the 
server no longer shows the self assigned IP.

I suspect the 4D 17 networking issues are related to computer sleep and/or the 
new network layer implementation of putting connections to sleep on the server 
after an inactivity timeout (the default is 20 seconds). I tested two changes 
over the past week: 

- Prevent the computer from sleeping when 4D Client is running.

- Disable the connection inactivity timeout - SET DATABASE PARAMETER(Idle 
connections timeout;0).

The logs showed only one client session that was aborted. I also ran a client 
test for over a week that implemented delays on both the client and server side 
ranging from a minute to 2 hours. No issues.

I had previously tried setting Idle connections timeout to 5 minutes. That did 
not help, there were still aborted connections.

If this is not a 4D Server problem, I'm not sure what else could be done to fix 
it. There were no issues like this with 4D 16.4. This is a single switch 
network, no routers are involved. The switch is about 6 months old and has no 
configurable settings.

Re: Window reverse layering issues

[Chip Scheide via 4D_Tech]

how about...
a bit clunky - but should work

when you open the modal dialog on top of the non modal window, you grab 
the modal window's window reference.

then in the form event of the non-modal (I presume larger window)
during either On OUTSIDE CALL and/or ON ACTIVATE:
Hide Window()
Show window()

You have to issue Hide Window, otherwise Show Window does nothing.
This will bring the modal window to the front, removing the double 
square cursor

BTW - the user can also use  to swap window positions if one 
gets hidden.

Side Note: this can be avoided on a Mac by using window type 34 (sheet 
window) then the dialog shows up as a 'pop down' window and is part of 
the main window.

Re(2): Window reverse layering issues

[Don Lapin via 4D_Tech]

Hi Steve,

Right now I do this, which works within the same process, but not coming from 
another process and clicking on the wrong window. Where would I fold in the 
process ID?

Thanks,
Don

case of

: (Form event=On Deactivate) & (bCnDlg=0) & (bOKdlg=0) & (bPrint=0) & 
(bMyCnfmOption=0) 

If (Current process=Frontmost process) 
  BRING TO FRONT(Current process)
End if 

end case
