I have modified your code, now it works fine..
procedure TForm1.Button1Click(Sender: TObject);
Var
StrArray : Array of String;
I :integer;
begin
SetLength(StrArray,20);
Try
For I := 0 to 19 do
begin
{Popoulate array}
Strarray[I]:= IntToStr(I) + 'Data';
{Show what has been populated}
Showmessage(StrArray[I]);
end;
Finally
{Clear array and set to zero}
SetLength(StrArray, 0);
end;
end;

Hello!
I am using Delphi 5. I need to work with Dynamic arrays. Reading in
the help file it says that:
'Once a Dynamic array has been allocated, you can pass it to the
standard functions Length, High and Low. Length returns the number of
elements in the array, ...'
I can't seem to get this to work. When I try to compile I get this
error:
'[Error] Unit1.pas(34): Record, object or class type required'
Here is some sample code I used to try to figure out how to work with
dynamic arrays:
procedure TForm1.Button1Click(Sender: TObject);
Var
StrArray : Array of String;
I :integer;
begin
SetLength(StrArray,20);
For I := 0 to 19 do Strarray[I]:= IntToStr(I) + 'Data';
label1.Caption := IntToStr(Strarray.length); <-----Error here
end;
************ End of code *****************
What am I doing wrong? I realize this code is contrived but I should be
able to derive what the size of an array is via this method, right?
Thanks in advance!
