Change the value of other Unit.

Hi,
How can i for example change the value of a variable in Unit1, in the code of Unit2?
Thanks!

Add Unit1 to Unit2 "uses" section. But lookout for circular unit reference. If you use unit2 in unit1 too then you must add unit1 in implementation section in unit2 (add "uses" after implementation if it doesn't exists)

That was what i thought to, but it doesnt seem to work:
In Unit1 the string variable path is set:

Code: [Select]

Unit2.Path:='Kampagne\Tutorial.txt';
Then Form2 is shown, and in the OnShow event of Form2 the code is like this:

Code: [Select]

Form2.Caption:=Path;
But The Caption of Form2 does not change. What have i missed.

Thanks!

If caption doesn't change, maybe your event (onShow?) is not executing?

When you do like this:

Code: [Select]

procedure TForm1.Button1Click(sender: TObject);
begin
  form2.caption:='test';
end;That is exactly the same thing you are after, a reference to another unit. My guess is you are missing a small typo or something.

In Unit1 the string variable path is set:

Where exactly in the Unit1 the variable is set? Is it in an event handler?
