TPQServer

[Natter]

Hi,

When you create a Postgresql object using TPWServer():New (), you are prompted to confirm that you are accessing the database. Is it possible to avoid automatically opening this query ?

pass all Parameter and it will not ask you

Code: Select all  Expand view  RUN

  oServer   := TPQServer():New( cHost, cDataBase, cUser, cPassword, , cSchema )

I pass all the parameters in, but the confirmation window still opens.

Can there be source code of TPQServer class ?

for me it work ... hm

this is a Test Code from HMG

Can there be source code of TPQServer class ?

are you asking for Source
i have this

PostGreSQL wrapper for MiniGUI (libpq)

Contributed by Viktor Szakats
Arranged for MiniGUI by Mitja Podgornik

Script makelib.bat creates PostgreSQL wrapper lib for Harbour (../Harbour/lib/hbpgsql.lib) and transforms
original libpq.lib in this map (MSVC COFF type) to Borland OMF type (../Harbour/lib/libpq.lib)

All headers and libpq.lib are from PostgreSQL version 8.4

5.5.2011

Mitja Podgornik


Updated:

PostGreSQL wrapper from harbour-core (https://github.com/vszakats/harbour-core)

All headers and libpq.lib are from PostgreSQL version 9.5

Petr Chornyj <myorg63@mail.ru>

but i can't attach (upload) it here so please write a Email to "AUGE_OHR" at WEB.DE

i include Directory 8.4 and 9.5 LIB of PostgreSQL and *.h files

it have buildlib64.bat / tpostgre-64.hbp but IMHO include LIB are for 32 BIT so i had Problem to build 64 Bit LIB
MakeLib.bat is not complete so do NOT run it

you need re-write tpostgre-64.hbp for 32 Bit ( just remove "-64" ) and change Path in buildlib64.bat to FiveWin and BCC
have not try it yet under FiveWin so i don't know if there are more Problem.

Thanks
