Trim

[Henry Olive 5]

I wish everyone a healthy day

 

Edit1.Text := 'AA BB'

MyVar := Trim(Edit1.Text);  // MyVar is still AA BB,  i was expecting to get AABB

 

Thank You

You may want to look at the online documentation of Trim(..), emphasis by me:

Quote

Trims leading and trailing spaces and control characters from a string

Source: System.SysUtils.Trim - RAD Studio API Documentation (embarcadero.com)

 

You don't want to remove leading and trailing spaces, you apparently want to remove all spaces.

Do this by "replacing" the spaces with an empty string, like 

myString := myString.Replace(' ', '');

Are you looking for something like this?

{! <summary>
Remove all characters in aSet from the passed string and return the
resulting string</summary>}
function RemoveCharsInSet(const S: string; const aSet: TSysCharset):string;
var
  I: Integer;
begin
  Result := S;
  for I := Length(S) downto 1 do
    if S[I] in aSet then
      Delete(Result, I, 1);
end;

{! <summary>
 Remove all characters considered whitespace from the passed string
 and return the resulting string</summary>}
function RemoveWhitespace(const S: string):string;
const
  Whitespace = [#0..' '];
begin
  Result := RemoveCharsInSet(S, Whitespace);
end;
