use structs which also contains structs and many other items, so it would look like this:


void func( MyStruct mystruct=MyStruct(MyStruct2(),MyStruct3(),2,3,4,"anystring" ) );

Am i right?? I think so.

AND another problem is, that if i want to check it in the function, if it is a default, so i have to provide an additional variable:

void func( MyStruct mystruct=MyStruct(MyStruct2(),MyStruct3(),2,3,4,"anystring",1 ) );...void func(MyStruct mystruct=MyStruct(MyStruct2(),MyStruct3(),2,3,4,"anystring",1 ) ){if(mystruct.isDefault==1)//isDefault->last parameter {...}else {...}}

if ( mistruct == MyStruct() )

Maybe i am totaly wrong, but i think, i got the error because setting a default value for a struct can not be done so easy.

and here is the console based application code -
Foo.h

class __declspec (dllimport) CFoo
{
public:	
    CFoo();	
    int foo1();	
    int foo2();
};

__declspec (dllimport) CFoo foo; 

test.cpp
#include "foo.h"
int main()
{	
    int i = foo.foo1();	
    i = foo.foo2();	
    return 0;
}

Don't forget to set the dependency to Foo.lib file in the test project settings.
Hope this will help.
