i have function named showelp but it is called from control.inc

[tanakian]

in my unit1.pas i have function named ShowHelp, however, when i call it from Form1 method, it calls one from control.inc: procedure TControl.ShowHelp;

is that correct?

That is because you're calling it from the wrong place of code

Rename your function to something else to make it easier.

"ViewHelp" springs to mind

Specify it by prefixing with the unit name

Code: Pascal  [Select][+][-]

1. unit1.ShowHelp()

That way your showhelp will be called instead of the method TControl.ShowHelp().

But as others suggested it may be better to choose a different name, although the above suggestion works fine.

If your ShowHelp is part of the form, i.e. if it is a method, declare it override.
TControl.ShowHelp is virtual.

Code: Pascal  [Select][+][-]

1. type
2.    TForm1 = class(TForm);
3.    private
4. ....
5.    public
6.        procedure showhelp;override;
7.    end;
8. implementation
9.  
10. procedure TForm1.ShowHelp;
11. begin
12.    Showmessage('form1 help');
13. end;

That will also work and probably the best option.
