Hi Chris, Hi Wolfgang,

I have found it!!

See Picture

SqlDB is True !!

but

Do While ! SqlDB:Eof
Server:=SqlDB:FIELDGET(#pgserverip) -> there the crash
ENDDO

will called.
And then this Error. That is only in Release Version is coincidence, because coincidence. I can reproduce this with Debug Version.

Strange. And Intellisense is not more active, again.

Hi Frank,

So what happens when you step over this line, an error message with the exact exception information should pop up.

Btw, there is a possibility that the highlighted in yellow color line of code is not really executed, in some cases the debugger shows one line below or above the actual line (this is in our todo list to fix). Please change the code like this:

Do While ! SqlDB:Eof
local dummy as int
dummy := 1
dummy += dummy
? dummy
Server:=SqlDB:FIELDGET(#pgserverip) -> there the crash
ENDDO

and step over the code again, does it stop again in the fieldget() line, even when SqlDB:Eof == true?

Hi Chris,

the Error after this Call is:

See the different values in Debugger:

Solution is to call SqlDB:gotop() after the Select. I don´t know if this is only with SqlSelect.
