Hi, everybody.
I'm using KOL - Key Objects Library.

Need a dialog to select multiple folders.
This option works for text files.
procedure click button2(dummy: pointer;Slender: Control; var mouse:TMouseEventData);
var s: String;

begin
Dialog: = NewOpenSaveDialog ( " , FileFullPath ('Project1.exe'), [ OSFileMustExist, OSHideReadonly, OSAllowMultiSelect, OSOverwritePrompt, OSPathMustExist ] );
dialog.Filter:= '*.txt/*.txt|all/*.*';
Dialogue.OpenDialog: = true;

 if Dialog.Execute then / / else exit;
s:=Dialog.Filename; k:=-1;
while s < > " do
                  begin
                        inc(k);
                        a[k]:=Trim( Parse( s, #13 ) );
                        s: = Trim( s );
          end;

form.Caption:=inttostr(k);
Forms'.Add2AutoFree (Dialogue);
end;
Q: how to do for multiple folders?

I'm amazed to see people still use Delphi these days.

Maybe this can help : http://www.gtro.com/delphi/gtrocheckshelltreeview_e.php

You can add a TFileOpenDialog with the options...

• fdoPickFolders
• fdoAllowMultiSelect

  with TCustomFileOpenDialog.Create(nil)do
    try
      Options := [fdoPickFolders,fdoAllowMultiSelect];
      if Execute then
        begin
            // Do something
        end;
    finally
      Free;
    end;

How to acsses to info that will be managed by this Tcustom dialog?

Title := 'Some Title';

FileNameLabel := 'Some Label';

OkButtonLabel := 'Some Button Label';

and Files is a TStringList of your selected folders
