Nu vil jeg så gerne vide hvordan jeg tilføjer noget tekst og en tekstbox -evt. en Messagebox ved klik på en knap, så jeg lige har noget at gå ud fra.
Hej Søren Nej, det har jeg dog ikke, men vi gøre det!
Men det ville være til stor hjælp hvis lige du gad og tilføje en Button, og når man så klikker på den kommer der en messagebox med Hello World... Det ville hjælpe mig meget på vej!
Hmm jeg bruger Dev-C++! -den kompilere det vel selv? -Hm hvis nu kun jeg skal ha' en "label" indeholdende noget tekst på min kode, ville det være advanceret?
Jeg har fundet du af hvordan kan får en MessageBox frem ved at klikke på selveste formen... Tror du så ikke du kan finde frem til at placere en knap på formen? -forgår det ikke på nogle lunde sammme måde?

Definerer en unik id til vinduet (en knap er pr. definition et vindue):
hMenu Identifies a menu, or specifies a child-window identifier depending on the window style. For an overlapped or pop-up window, hMenu identifies the menu to be used with the window; it can be NULL if the class menu is to be used. For a child window, hMenu specifies the child-window identifier, an integer value used by a dialog box control to notify its parent about events. The application determines the child-window identifier; it must be unique for all child windows with the same parent window.
Jeg satte også denne kode ind: #define ID_DAMN_KNAP 102
Hvilket er i samme stil som indholdet af "resource.h" fra 13:09:25.
