MyArray:={ {'campo1', 30}, {'campo2', 50}}

for n = 1 to len(MyArray)

// How make it ?
// #define MyArray[n][1] MyArray[n][2]

next n

msginfo(campo2) // need return 50

i maked it

// it´s OK more is define campo2 as 50 only inside this function when i try msginfo(campo2) in other function
// give me erro variable no exist.
&( " "+Alltrim(MyArray[n][1]) +" := " + Alltrim(str(MyArray[n][1])) )

i try make it too.

&( "Public "+Alltrim(MyArray[n][1]) +" := " + Alltrim(str(MyArray[n][1])) )

More give me erro.

Someone can help ?

Sorry, I don't understand what you're trying to do. Can you rephrase your question?

METHOD Events() CLASS MyActiveX
local act, oReg, cTypeLib, aEvents

oReg := TReg32():New( HKEY_CLASSES_ROOT, "CLSID\" + ::cString + "\InprocServer32" )
cTypeLib := oReg:Get( "" )

if ! Empty( cTypeLib ) .and. File( cTypeLib )
aEvents = ActXEvents( cTypeLib, act:hActiveX )
endif
for n = 1 to len(aEvents)
#define aEvents[n][1] aEvents[n][2] // problem aqui :) no stay defined ...
next n

Return nil

other sample

MyArray:={ {'campo1', 30}, {'campo2', 50},{'kakaka',100},{'mouseon',20},{'click',-12} }
// this Array i receive in function ActEvents of fivewin. it´s only sample. no return always same array.

for n = 1 to len(MyArray)

#define MyArray[n][1] MyArray[n][2]
next n

Code: Select all  Expand view
FUNCTION MAIN()

    LOCAL aArray := { { "SYMBOL1", 10 }, { "SYMBOL2", 20 } }

    LOCAL i

    FOR i = 1 TO LEN( aArray )
        &( "M -> " + aArray[ i, 1 ] + " := " + LTRIM( STR( aArray[ i, 2 ] ) ) )
    NEXT

    ? M -> SYMBOL1
    ? M -> SYMBOL2

    RETURN NIL

In order to see data outside the class it has to be defined as data of the class.

Code: Select all  Expand view
class myActiveX
   data aEvents
   ...
endclass

Now you can access aEvents:

MsgInfo( oActiveX:aEvents[1][1] )

MsgInfo( oActiveX:aEvents[1][2])

You cannot use #DEFINE to define data of the class.

Or, if you want to make a class for each type of ActiveX that you are using, then you can define all the event names as data of the class, then you can assign the values to them when the object is initialized. Then you can access each event from outside the class.

Code: Select all  Expand view
// ActiveX calendar class
CLASS calendar from TActiveX
   DATA Campo1
   DATA Campo2
endclass

Method new()
   ...
   aEvents = ActXEvents( cTypeLib, act:hActiveX )
   ::Campo1 := aEvents[1][2]
   ::Campo2 := aEvents[2][2]
   ...
return self

oCalendar := calendar():new()

msgInfo( oCalendar:Campo1 ) // returns value, e.g. 30

Here is another way you could do it. Create a method getEvent() and pass it the name of the event to get the value.

Code: Select all  Expand view
method getEvent( cEvent )
  local uValue, i
  cEvent:= upper(alltrim(cEvent))
  for i=1 to len( ::aEvents )
     if upper(::aEvents[i]) == cEvent
        uValue:= ::aEvents[i][2]
     endif
  next
return uValue

msgInfo( oCalendar:getEvent("campo1") )  // returns 30

If you haven't already read them, there are some articles on writing FW classes on my website at http://www.gointellitech.com.

To get the value 50 on the second element of second sub-element is like this (as I understand your code):

....
LOCAL aX

MyArray:={ {'campo1', 30}, {'campo2', 50}}

FOR EACH aX IN MyArray
IF aX[2] == 50 //second sub element of MyArray var
msginfo( aX[1] ) //as 'campo2'
msgInfo( aX[2] ) //as 50
END
NEXT
.....

Frances,

That may work but assigning value to PUBLICs inside a class is not good OOP practice. It kind of defeats the purpose of having a class. The data should be stored inside the class.

James
