I have a problem to read the data of screen resolution.
With the command

nWidth := AppDeskTop():currentSize()[1]

an error is displayed:

oError:args :
-> VALTYPE: U VALUE: NIL
oError:canDefault : N
oError:canRetry : N
oError:canSubstitute: J
oError:cargo : NIL
oError:description : Parameter hat falschen Typ
oError:filename :
oError:genCode : 2
oError:operation : currentSize
oError:osCode : 0
oError:severity : 2
oError:subCode : 1025
oError:subSystem : BASE
oError:thread : 1
oError:tries : 0

Include files are std / xbp / appevent.ch are foreseen.
Has anyone an idea what I have missed?
Thanks in advance
Dieter

This makes no sense.

It appears that AppDeskTop() is not returned an XbpIWindow() object.

Are you compiling and linking in GUI mode?

Hello Roger,
many thanks for your hint. The definitions in the XPJ-file were
GUI=yes
LINK_FLAGS= /PM:PM
but that was not enough.
Following your hint I added at
COMPILE_FLAGS= ../dEXPRESS19 !
And that worked.
Thank You

Dieter
