Delphi counter help

procedure TForm1.Button1Click(Sender: TObject);
begin
i := 0;
Edit1.Text := (i + 1);

When i click the button i want it to count "score", so everytime i click it will go 1,2,3... so on

when i try to compile it says [Pascal Error] Unit1.pas(32): E2010 Incompatible types: 'string' and 'Integer'

Well, read the error. It is telling you you are mixing types.

ToString

Try

procedure TForm1.Button1Click(Sender: TObject);
begin
i := 0;
Edit1.Text := (i + 1).ToString;

Furthermore, every time Button1 (very good naming convention) is clicked the variable i will be reset to one.

Declare it outside of your procedure.

I believe the function to convert int to string in delphi is IntToStr(),

so that would be

procedure TForm1.Button1Click(Sender: TObject);
begin
i := 0;
Edit1.Text := IntToStr(i + 1);
end;

Well, the variable is still a Integer, we just need to convince the textbox that the value is okay to be assigned.

Also you cannot do string = string + 1. Well perhaps you can but that is more like a concatenate.

How do i do that?

i'm very new to this

[bfsog]

You do it after any type definitions and before implementation.

You do it after any type definitions and before implementation.

so i make i := 0; after:

var
  Form1: TForm1;
  i : integer;

so it should look like this

var
  Form1: TForm1;
  i : integer;
  i := 0;

but when i try to run, it says

[Pascal Error] Unit1.pas(25): E2004 Identifier redeclared: 'i'

[bfsog]

Is that on the initial run or when you click the button?

Take out the i:= 0 line in the button click event so your procedure will be something like

procedure TForm1.Button1Click(Sender: TObject);
begin
i := i + 1
Edit1.Text := (i).ToString;
