Using VS2008 Managed C++ to wrap a dll. The native method takes a series of single const char* values and a collection of char* values. Going to make an example function:

Function1(char * value1, TF_StringList& catList);  

TF_StringList is a dll class with 3 insert methods, the one I want to use is:

TF_StringList::insert(const char* str);  

So I set up a wrapper method of:

WrapperClass::callFunction(String^ mvalue1, ArrayList mcatList);  

mvalue1 is converted to const char* using:

const char* value1 = (char*)(Marshal::StringToHGlobalAnsi(mvalue1)).ToPointer();  

However, when a get to the collection of strings, I iterate over it getting each string using the index:

String^ mstr = mcatList[i];  

Have tried every way of converting String^ to const char* and in every case the TF_StringList::insert(const char* str) method throws a C2663 error which has to do with the const-ness of the value. What is the problem?
