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
