E ovako, ja sam programer ali do sada nisam nikada u ovom programu radio, imam iskustva sa C++ ali to je do sada uglavnom bilo u radu sa devc++, e sad da pocnem pricu o problemu, napravim program win32 obican i sad (prvi mi je program hocu da napravim digitron (prosto nesto dvije tekst kutije i 4 dugmeta za operacije)) kliknem desnim klikom na folder Source u "solution explorer"-u>add>windows form i sad, nesto me pita da konvertujem projekt u neku stvar, (mislim da nije vazno pa kliknem na ok) i sad napravim ja to sve i sad ne znam da li ja sad taj header fajl da includujem u glavni cpp fajl ili sta i kad includujem prijavljuje nekih milion gresaka a kad ne includujem (stavim da se klikom prikaze messagebox) prijavi gresku

Citat:1>c:\documents and settings\nenad l\my documents\visual studio 2008\projects\digitron\digitron\forma_digitron.h(144) : error C2065: 'NULL' : undeclared identifier
1>c:\documents and settings\nenad l\my documents\visual studio 2008\projects\digitron\digitron\forma_digitron.h(144) : error C2065: 'MB_OK' : undeclared identifier

Moze li mi neko pomoci i objasniti kako se ovo radi...

Jos kad bi napisao u koju stvar i to sve i sad taj header isto, i to sto include-ujes i sta nije vazno ... mozda bi ti neko i pomogao.

Problema sa kontantama i header-ima u Visual-u ces svakako imati. Ako su ti samo ovo greske, onda definisi sam NULL kao 0,a MB_OK kao neku pozitivnu vrijednost .. mada sumnjam da ce to biti jedine...

Ok

Evo sta mi kaze kad ubacim windows form u source

  1. You are adding a CLR component to a native library. Your project will be converted to have common language runtime support.

E ovako, greska je bila u tome da pri kreiranju treba da izaberem CLR pa Windows form application, i tek onda je sve pravilno linkovano i sredjeno...
