Hallo,

Ik zou een functie "bewaren" willen schrijven en in die functie een caption van een Edit field aanpassen: bv





void bewaren(void)
{
Edit1->Caption = "Hallo";
}

Wanneer ik dit compileer dan bekom ik een undefined symbol linker error omdat Edit1
niet gekend is binnen de functie.

Op andere plaatsen in de Form kan ik Edit1 wel zonder problemen aanpassen.

Graag een oplossing,

Mvg
 
Je kunt de functie 'bewaren' binnen de scope van de klasse plaatsen. (er zijn nog wel meer mogelijkheden)
 
Hello bedankt, maar kan je misschien meer informatie geven, hierbij mijn Header file:
Helemaal onderaan zie je void bewaren(void) !

met dank,

Zoiets zou moeten werken. :)
