ini파일을 이용하여 아래와 같이 파일을 만들었는데

이파일을 open했을때 각 component로 이값을 가져올려니까 잘 안되네요

부탁좀 드립니다



=====ini 파일에 섹션,키, 키값넣기=======================

============ 키값가져오기============================





if opendialog1.Execute then

begin

f_data:=opendialog1.filename;

f:=tinifile.create(f_data);

{form2}

tit:=f.readstring('presentation','title','');

des:=f.readstring('presentation','description','');

f_data:=f.readstring('presentation','inputfile','');

COMF4:=f.readstring('material propeties','COMF4','');

{form4}

TLENGTH:=f.readstring('Geometry','TLENGTH','');

P:=f.readstring('Geometry','P','');

DN:=f.readstring('Geometry','DN','');

f.free;

end;



이렇게 코딩했는데 readstring 의 각 파리미터중 키값파리미터을 어떻게 써야 하는지

위와같이 ''로 하니까 null 값을 가져오드라구요

ini파일에 있는 키값을 가져오도록 하고 싶거든요

부탁좀 드립니다
