Remember selected directory path.

[Zath]

How do I store a directory path for reuse once selected with SelectdirectoryDialog ?
I found Tinifile after searching here but can only find TIniPropStorage in my components.
The path is stored as drName.
I tried Edit1.text.Savetofile ('drName\myfile.ini');
I tried with a memo and used memo.lines.savetofile ..

Does the file need to exist first or can I create ini or txt files on the fly ?

Thanks for any guidance.

Code: [Select]

uses inifiles, ......
procedure savetoini(const aFileName:string);
var
  vIni : TIniFile;
begin
  vInit := Tinifile.Create(aFilename);
  try
    vini.writestring('Main','CurrentPath',MySelectedPathVar);
  finally
    vini.free;
  end;
end;

Thanks Taazz, that'll help me move on.

So the savetofile method was the wrong route to take ?

[taazz]

not all components have a savetofile method and those that they do they support some specific format ee the memo saves everything to a text file. There is no component that will save to an ini format directly that I'm aware of.

There's no real reason it has to be an ini file I suppose, a text file would work I presume.
I went the ini route as it seemed the correct option.

Tinifile has a format of varname=varvalue a plain text file does not give you that information with out extra coding and if you are going to code the above behavior any way why not use the ini files from the start

Sounds good to me.

Ok, thanks for your help.

A little more info please.

Do I use this line when I want to read in from the file too ?
TInifile.Create(aFilename)

There's no TInifile.Open I presume.

Thanks

Yes, I'm on that now but still struggling to reopen the ini and get the info back.
Currently setting the readstring on my Form Oncreate event but not quite there yet.

Yes the code should be used as it is for reading too just change the writeSTring method call to readString and be aware that the last value is the default value that will be returned in case that the VarNAme is not found in the Main section in the ini file.

Are there more values written into the ini file?

Are there more values written into the ini file?

Eventually there will be.
I'll be adding multiple headings and data lines.
