## _delete

Hi,

I am very new to C/C++ Programming...

Please let me explain what the following code will do.

#define Check(CN,VC) \

static void CN ## _save(WSDserialize*,void* ){} \

class CN ## _init \
{ \
public: \
CN ## _init() \
{ \
WSCbase::setCreateHandler(#CN, CN::createInstance); \
} \
~CN ## _init() \
{
WSCbase::setCreateHandler(#CN, NULL); \
} \
}; \



For this they are passing two class name as follow

Check(One,Two)

In my directory i have both One.cpp and Two.cpp

I am not aware of ##.

Regards

Udhaya

re: ## _delete

Thanks..One more doubt is

I understood that..

Some places they are using just #CN ...

I understand this is as Converting CN to some data type..

am i right..?
