Hello, P& A.

Would you please translate what is written on this error message into English?

Try replacing DoMessageBox() function with asynchronous ShowMessageBox().

If you have created a new infobase in 8.3.6, you have prohibited of using modal dialogs. This option is set in the configuration tree root.

Hi Timofey.
Message : Prohibit use the Status window mode at this !
I used in thin client --> it's ok, 1C Enterprise it error
how can i do it ?

And i can't debug functon &AtServer when i put debug.

You can set modality usage mode in properties of configuration tree root: Properties -> Compatibility -> Modality usage mode

You also need to start 1C:Enterprise 8.3 Server Agent with -debug param to allow debug at server:
Control Panel -> Administrative tools -> Services -> 1C:Enterprise 8.3 Server Agent properties and change command line for it. For example
Before:
""C:\Program Files (x86)\1cv8\8.3.4.317\bin\ragent.exe" -srvc -agent -regport 1541 -port 1540 -range 1560:1591 -d "C:\Program Files (x86)\1cv8\srvinfo""
After:
""C:\Program Files (x86)\1cv8\8.3.4.317\bin\ragent.exe" -srvc -agent -regport 1541 -port 1540 -range 1560:1591 -d "C:\Program Files (x86)\1cv8\srvinfo" -debug"

Or you can do this with regedit
Find [HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\services\1C:Enterprise 8.3 Server Agent\]
Find property "ImagePath"= , and add "-debug".
You need stop 1C:Enterprise 8.3 Server Agent before this changes and start after it

Hi all.
Thanks, i can do it.
