In C++ I have a char[256] variable that is populated by a call to an external DLL which fills it with data. From there I would like to add the char[] as a ComboBox item.

char name[256];
name[0] = "76";
comboBox1->Items->Add(name);

This creates a build error because char[] is not a type of System::Object. Any ideas on converting the char[] to something I can add as an Item to a ComboBox control? Converting to a string would be just fine but I'm not sure quite how to do that. Plus if I try to create a variable such as:

string strName;

also creates an error for missing ';' before identifier 'strName'. I'm a beginner to C++ and am still getting my brain wrapped around it so thanks for any help provided!

string strName;

First, you need to #include <string> in order to use std::string. Secondly, you need to add using namespace std; to your unit in order to refer to a std::stringas string. Alternatively, use the plain std::string strName instead. It's a matter of taste. Using the fully qualified form avoids polluting your namespace with all the identifiers from std.

To the main question:

gcnew String( text.c_str() );

This should do the conversion. text is your std::string instance and the result of the expression is the string object you need to pass to Add.

your second problem sounds like your missing the include for the string class, so just add #include <string> to the top of your file, you may also need to add using namespace std; or use 'std::string' depending on your system

Try string strName(name); (on the assumption you have your includes and namespaces right...)

UPDATE: It looks like it's System::String you need to use, not the STL string.
