Problem sa WinApi-jem ??????i nikada nisam imao problema,ja ne vidim u cemu je problem,gde gresim,nece ni obican prozor da mi napravi.
Koristim Visual Studio 2005,a i pokusao sam kompajlirati i preko Free Command Line Tools-a,i nece,
prijavljuje gresku oko kastovanja,guglovao sam i nalazio primere neke i tutoriale,ali
code je bukvalno isti ali moj ne radi,a ni code iz tutoriala ne radi,sto je cudno jer je to tutorial,moze li neko da pogleda i da mi kaze gde gresim,hvala unapred.
Code:
#include <windows.h>
const char ClsName[] = "proba";
LRESULT CALLBACK WndProcedure(HWND hWnd, UINT Msg,WPARAM wParam, LPARAM lParam)
{
switch(Msg){
case WM_DESTROY:
PostQuitMessage(WM_QUIT);
break;
default:
return DefWindowProc(hWnd, Msg, wParam, lParam);
}
return 0;
}
INT WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,LPSTR lpCmdLine, int nCmdShow)
{
MSG Msg;

WndClsEx.lpszMenuName = NULL;
WndClsEx.lpszClassName = ClsName; // ovo kad kastujem (LPCWSTR)ClsName kompajler pokazuje jednu gresku manje
WndClsEx.hInstance = hInstance;
WndClsEx.hIconSm = LoadIcon(NULL, IDI_APPLICATION);
RegisterClassEx(&WndClsEx);
// i kod ove f-je mi javlja gresku ali nemogu da je neutralisem :(
hWnd = CreateWindowEx(
