Başlık: vc++ global nesne tanımlama - nasıl ?
Gönderen: magnetron - 23 Temmuz 2013, 19:33:05
merhaba forum,

projemde bir form oluşturdum ve bu forma bir buton ve winsock kontrol ekledim
şimdi başka bir *.cpp dosyasında bu class'ın bir nesnesini oluşturmak istiyorum

mesela aşağıdaki kod örneğinde olduğu gibi

#include "MOCON1.h"  // MOCON clasın tanımlandığı dosya
......
MOCON * winsok ;  // 6.ncı satır


ama aşağıdaki hatayı veriyor

1>Compiling...
1>MyHardware.cpp
1>.\MyHardware.cpp(6) : error C2143: syntax error : missing ';' before '*'
1>.\MyHardware.cpp(6) : error C4430: missing type specifier - int assumed. Note: C++ does not support default-int
1>.\MyHardware.cpp(6) : error C2365: 'MOCON' : redefinition; previous definition was 'namespace'
1>.\MyHardware.cpp(6) : error C4430: missing type specifier - int assumed. Note: C++ does not support default-int


neden hata veriyor ? ne yapmalıyım ? teşekkür

Hocam namespace ile class adı aynı olduğundan hata veriyor. "MOCON" namespace adını değiştirip bir dener misiniz?

hocam class ismini değiştirdim

ve classın tanımlamasına hemen bir nesne tanımladım

bunu compile ettiğimde

1>Compiling...
1>MOTION.cpp
1>c:\documents and settings\xp\belgelerim\visual studio 2008\projects\mocon\mocon\MOTION.h(110) : error C3699: '*' : cannot use this indirection on type 'MOCON::MOTION'
1>        compiler replacing '*' with '^' to continue parsing

1>        may not declare a global or static variable, or a member of a native type that refers to objects in the gc heap


bu hatayı veriyor

eğer

#pragma endregion
} ^winsok;     // burada hemen nesne tanımlanıyor


bu şekilde tanımlarsam

bu C++ ne kadar karışıkmış C gibi güzel dil yok yani

bir yardım , teşekkür
