From 66792cd0244b0845612bf8e1150be024a18e9180 Mon Sep 17 00:00:00 2001 From: Viktor Szakats Date: Mon, 7 Dec 2009 02:17:37 +0000 Subject: [PATCH] 2009-12-07 02:58 UTC+0100 Viktor Szakats (harbour.01 syenar.hu) * include/hbwince.h + Added following macros to help transitioning to new method of CP conversion when interfacing with Windows API (both UNICODE and non-UNICODE): HB_PARSTR( n, h, len ) HB_RETSTR( str ) HB_RETSTRLEN( str, len ) HB_STORSTR( str, n ) HB_STORSTRLEN( str, len, n ) ; The goal is to replace HB_TCHAR_*() macros and hb_osEncodeCP() call with above ones. This will allow to use any CPs (even UTF8) on the .prg level and transparently interface with Windows with proper CP translation. We will probably need a few more macros to store strings in array elements f.e., but this is enough for a start. * contrib/hbwin/wapi_shellapi.c + Experimental: WAPI_SHELLEXECUTE() converted to use above new macros. It results in much cleaner code. Minor incompatibility: 3rd parameter is now passed as-is, so if non-string is passed it gets passed to Windows as NULL, which isn't a valid input parameter. ; NOTE: Probably it will useful to have HB_PARSTRDEF() which also accepts a default value to be used when non-string parameter was passed. (to replace old hb_parcx() calls). Is it possible to add such function or any other ways to solve that? ; TOFIX: I'm getting this warning: warning: implicit declaration of function 'hb_setGetOSCP' and it's probably too late, but I couldn't find a way to include hbset.h without errors or with least side-effects. Przemek, could you help? * contrib/hbwin/win_prn1.c * Formatting. * src/rdd/dbcmd.c * src/rdd/wafunc.c + Moved recently implemented codepage defaulting logic (_SET_DBCODEPAGE) to lower lever functions.
