[d2010]

Hello..
My chinese-exe-program, extract to Unicode'path  ...
C:Q1=How fileExists, inside "Lazarus"as widestring? (is main question).
 
Fist. I try small read wideparamstr(1)
Second. The source of problem, is my win8English contain chinese'path,
             The fileName is englishname as "pp_ddvslide.vlax"
My project1.lpr fileexists('D:....\pp_ddvslide.vlax') result as false.
Please you can use gfnFiles *. from PBuffer.zip as optionally, or
 other function/s from Lazarus4.00
 ..

Code: Pascal  [Select][+][-]

1. //Path...cosldlsp\Y+YYY¡+tY+-ª+ú\CNCNET-ª+ú\
2. Library  widefpat;
3. Uses windows;
4. Function wide_after0next(const aWid:widestring;elsewdef:widechar):widestring;
5. Var cnt,spc,dxf,dwg:integer;
6. Begin
7.  result:=elsewdef;
8.  cnt:=00;
9.  spc:=RTCAN;
10.  dxf:=RTCAN;
11.  for dwg:=01 to length(s098) do
12.     Case (s098[dwg]) of
13. widechar('"'): inc(dxf);
14. Widechar(' '): Begin spc:=dwg;
15.                      if (dxf=2) then break else
16.                         if (dxf<00) then break;
17.                end;
18.   End;
19.  if (spc>00) then result:=copy(aWid,spc+1,length(aWid)-spc);
20. End;
21.  
22. Var s098:widestring='';
23.      wideargw:widestring='';
24. Begin
25.   wideargw:=widestring(GetCommandLine,widechar('0'));
26.   s098:=wide_after0next(wideargw,'0');
27.   if (s098='0') then writeln('Argument 1  of project1.lpr is wrong') else
28.     Begin writeln('Input file1=',s098);
29.     End;
30.         readln;
31. End.

"function gfnsFilePathGet(sFile: WideString): WideString;"
"function gfnbFolderExists(sFolder: WideString): Boolean;"
"function gfnbFileExists(sFile: WideString): Boolean;"

I had found that prefix '\\?\' to file name sometimes help (not only with "max length path" limits).

Example:

Code: Pascal  [Select][+][-]

1.   filename := '\\?\D:....\pp_ddvslide.vlax';
2.
