[Tim Mulholland]

How can i (using Managed C++) convert a System::String object containing
basic text into a char* object?

Thanks in advance,

Tim

Here's one way :-

String* s1 = S"............" ;
const __wchar_t __pin* pstr = PtrToStringChar s(s1);

I think he meant a char*, as in single byte char*... Here's one way :

String foo= "Hello";
IntPtr ptr = Marshal::String ToCoTaskMemAnsi (foo);
char *singleByteFoo= (char*)ptr.ToPo inter();
// do stuff with singleByteFoo
Marshal::FreeCo TaskMem(ptr);
// here, singleByteFoo is not valid anymore
