SplitString

[Henry Olive 5]

I wish everyone a healthy day.

 

Uses System.StrUtils;

var

S, FirstStr, SecStr : String,

begin

  S := SqlQuery1.FieldByName ('RANGE').asString; // it is '5/10'

  FirstStr := SplitString(S, '/')[0];

  SecStr  := SplitString(S, '/')[1];

end;

 

Above code works in Delphi-XE w/o any problem but

i get   Not enough actual parameters err.msg in  Delphi 10.3

What is wrong ?

 

Thank You

I do not get any error here in 10.3:

uses
  Types, StrUtils;

var
  S, FS, SS: String;
  A: TStringDynArray;
begin
  S := '5/10';
  A := SplitString(S, '/');
  if Length(A) >= 2 then begin
    FS := A[0];
    SS := A[1];
  end;
end;

There is nothing wrong with the code you posted, other than the comma instead of semicolon after the "string" in the var section. Perhaps you have another SplitString function closer in scope than StrUtils.SplitString here. If you hover the mouse over SplitString, what does the code insight popup tell you where it's from?

In line #3 the list of variables must me terminated by a semicolon, not by a comma. Beside that your code works as expected (Delphi 11.0).

And because you did not tell in which line the error occours I can only wild guess that there is some other "SplitString" function in reach with uses different parameters.

Where do you land when doing a Ctrl+Click on "SplitString"?

semicolon, not by a comma

Well spotted! My eyesight is not up to that any more.

Thank you so much Alexander, Peter, Achim, Dany

I tested my code in 10.3 in a *new project* and noticed my code works,

then I copied the new project's Uses 

( Windows, Winapi.Messages, System.SysUtils, System.Variants, System.Classes,
 Vcl.Graphics, Controls, Forms, Vcl.Dialogs, Vcl.StdCtrls, System.StrUtils; )

 

I returned to my main project and paste the uses here and delete old uses

and my problem solved. 

 

Regarding the variable semicolon, in my original codes it is semicolon, comma is my wrong typo  

I'm very very sorry for misleading you.
