Ik vind het een beetje lastig om zo uit te leggen, voeg me maar toe op msn: paul @ dumpendiezooi . nl
(zonder spaties of course)
Ik ben ook zelf pas heel even bezig met de win32 api, ik was ook lang met die buttons bezig maar nu is het gelukt.

Andere gebruikers / bezoekers hebben hier misschien ook problemen mee. Het forum is bedoeld voor dit soort zaken, dus ik zie niet in waarom je hier je antwoord / tips / adviezen niet kan plaatsen?

Code:

HWND Button1 = CreateWindowEx(NULL,"BUTTON","De text op de knop",WS_CHILD |WS_VISIBLE | BS_PUSHBUTTON,10,10,200,25,hwnd,NULL,hThisInstance,NULL);

de hwnd (na de 4 getallen) is de pointer naar het scherm waar je het in wilt, hThisInstance snap je wel

MasterNoob · 8 jan 2009

De kleur etc veranderen kan niet zomaar, je kan wel eigen buttons maken (heb ik gehoord) daar heb ik verder ook niet echt veel ervaring mee.

Over 2 schermen dat het 1'ne knopje van scherm wisseld ga ik nu even een voorbeeld code maken, deze zal ik hier zo posten

oke

en wat bedoel je presies dat je knop je evranderd??

ik zal ff duiderlijekr zijn ik heb bijv knoppen waar een cijver op staat en als ik die strax in klik dat dat cijver dan bijv boven de knoppen blijft staan "in ene soort scherpje"
hoop dat ik nu duidelijk ben?? ik begewoon c++ aan het leren voor me zelf
ik heb hellow world gedana en toen een simpele rekenmachine en nu wil ik die rekenmachine knoppen en alles geven om het voor me zelf te leren hoe je zo iets maakt

ik heb alle knoppen onder tussen als ik meot ze ider ngo een functie geeven enzo
dat knopje 1 ook daad in werkelijk 1 in vuld enzovoort maar dan heb ik eerst dat "schermpje nodig" waar ik ze kan zien snappie

uhhm?

hey was ikw eer ff

zijn e rnog ander code worden voor die window text??

SetWindowText

dan maakt hij er ene vast cijver van ... dus als ik dan een 2e button toe voeg met cijfer 2

en de 1 was al ingevuld maakt hij van die 1 een 2 inplaats van die 2 er achter te zetten :S

sorry als ik zoveel vraag

ben blijkbaa rnog neit ver genoeg

MasterNoob · 11 jan 2009
