klasse innerhalb ein Form Implementieren

[aboooood86]

Hallo zusammen mein problem ist dass ich eine klasse innerhalb ein form und try nicht Implementieren kann. wenn ich das mach kommt folgende fehlermeldung: "Die Schachtelung ist nicht korrekt: Vor der Anweisung "Class" muss die mit "try" begonnen Kontrollstruktur durch "endtry" abgeschlossen werden " wenn ich try vor dem klasse mach dann riagiert nicht und der fehler bleibt noch. ich würde mich freuen wenn jemand mir damit hilft. so sieht mein code aus:

      CALL METHOD cl_salv_table=>factory

        IMPORTING

You cannot set a CLASS IMPLEMETATION in a TRY // ENDTRY.

You have to close the ENDTRY and to set a CATH before the statement CLASS ... IMPLEMENTATION.

The exception raised during the METHOD set_hotspot have to be catched during the call of this method.

And you have to add to the method set_hotspot_beleg a RAISING with your exception class

im sorry i couldnt understand u, i closed the try before the class statement. the second sentence i couldnt understand it could u please tell me how to do that?

When you create programs, either use subroutines (form ... endform) or methods but not both. Note that subroutines have been obsolete for a long time and should be used only if no other choice.

i did that already and thought i did somthing wrong cuz now the same error but with the FORM

cant i implement the class inside the FORM?
