for performance of executable

[ertan]

Dear Friends,

Which of the lines I marked should be used for more application performance?
Is there any difference between them in terms of performance?

Code: Select all  Expand view

#include "Fivewin.ch"

[b]STATIC oDBServer                  <--- for sql[/b]

FUNCTION Main
 LOCAL oApp

 oApp := MyApp():New():Run()

RETURN nil

CLASS MyApp FROM TMdiFrame

[b]DATA oDBServer                    <--- for sql[/b]

ENDCLASS

-----------------------------

CLASS TWindow
.....
[b]DATA oParent                                <---[/b]
.....
ENDCLASS

-------- OR ---------

[b]__objAddData( oMain, "oModule" )  <---[/b]

oMain:oParent := oModule

 

Best regards,
Ertan

Sorry,

Code: Select all  Expand view

oChild:oParent := oModule

oParent wrong variable name. oWnd == oParent

This is correct code.
Which is correct choice for this two state?

They are for different purposes. Module level STATIC (ie. a STATIC defined outside any functions) is a single variable that all the functions in the module can see. DATA instance variable is a variable incapsulated inside an object instance (ie. one different variable with the same name for each object instance). You have to choose the right one for your needs not for its performance.

Thank you so much Enrico
