AFAIR, there already is a bug report+patch in the bug tracker onextending TInifiles. At least if it saves (and presumably expects) 0 and 1 it's protected from internationalisation issues e.g. if a template .ini is supplied with an app. I hacked a wrapper some while ago for my own use, which tries to preserve the form of the variable (i.e. if it's currently True then False is written, but if it's yes then no is written). That's obviously massively problematic if multiple languages have to be supported. -- Mark Morgan Lloyd markMLl .AT. telemetry.co .DOT. uk [Opinions above are the author's, not those of his employers or colleagues] ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal

In the case of fpGUI (as as an example), the fpgui/src/build.bat or build.sh builds the fpGUI framework and places the compiled units in a library output directory fpgui/lib/fpctarget The examples/demos of fpGUI doesn't recompile the fpGUI framework, it simply uses the *.ppu and *.o files located in the 'lib/target/' directory. See the extrafpc.cfg files in the demo directories. Here is a snippet: -FUunits -Fu../../../lib/$fpctarget Not the -Fu doesn't reference the fpgui/src/ directory, but rather the lib directory.

Yes, simply create a descendant of TINIFile, override the WriteBool() virtual method and use BoolToStr() instead of BoolToChar() in its implementation. The same then needs to be done for ReadBool() as well.

[fpc-pascal] Syserrormessage, parameter data type
In my programs I use this code quite often:
SysErrorMessage(GetLastError);
But recently my program had a range check
error which let me have a look at the definiton
of the 2 functions GetLastError and SysErrorMessage.
GetLastError is from the WinAPI:
---
function GetLastError:DWORD; external 'kernel32' name 'GetLastError';
---
and SysErrorMessage is from SysUtils:
---
function SysErrorMessage(ErrorCode: Integer): String;
const MaxMsgSize = Format_Message_Max_Width_Mask;
var MsgBuffer: pChar;
begin
GetMem(MsgBuffer, MaxMsgSize);
FillChar(MsgBuffer^, MaxMsgSize, #0);
FormatMessageA(FORMAT_MESSAGE_FROM_SYSTEM,
nil,
ErrorCode, - 3rd Parameter
MakeLangId(LANG_NEUTRAL, SUBLANG_DEFAULT),
MsgBuffer, { This function allocs the memory }
MaxMsgSize, { Maximum message size }
nil);
SysErrorMessage := StrPas(MsgBuffer);
FreeMem(MsgBuffer, MaxMsgSize);
end;
---
GetLastError yields a DWORD but SysErrorMessage expects an INTEGER.
Why? This raises a range check for all error codes 2^31.
A closer look at SysErrorMessage shows that the ERRORCODE will
not be used in this routine but only handed over to
FormatMessageA which expects a DWORD!
---
function FormatMessageA(dwFlags:DWORD;
lpSource:LPCVOID;
dwMessageId:DWORD;- 3rd Parameter
dwLanguageId:DWORD;
lpBuffer:LPSTR;
nSize:DWORD;
Arguments:va_list):DWORD; external 'kernel32' name
'FormatMessageA';
---
So if GetLastError gives a DWORD and FormatMessageA expects a DWORD
shouldn't SysErrorMessage use a DWORD too?
