I apologize for my ignorance, but...

I have a char array that I need to output to a textbox. I have this now...

     Memo1->AppendText("    Item Name: " + Msg.ItemName8[0].ToString() + "\r\n");

Obviously, this only outputs the ascii value stored in [0] of the array. What is the best way to output the full array in ascii characters???

Code is helpful here :)

Thanks!

Jase...

That is what I had thought too, but I can't get around this compiler error:

error C2228: left of '.ToString' must have class/struct/union type is 'unsigned char [16]'

Tried that too... I get the following:

error C2679: binary '+' : no operator found which takes a right-hand operand of type 'unsigned char *' (or there is no acceptable conversion)
        could be 'built-in C++ operator+(volatile const System::Object ^, volatile const System::String ^)'
        or 'built-in C++ operator+(volatile const System::String ^, volatile const System::Object ^)'
        or 'built-in C++ operator+(volatile const System::String ^, volatile const System::String ^)'
        while trying to match the argument list '(System::String ^, unsigned char *)'

If I try the String( ... ) option, I get:

error C2440: '<function-style-cast>' : cannot convert from 'unsigned char [16]' to 'System::String'
        No constructor could take the source type, or constructor overload resolution was ambiguous

I ended up doing the following and it is working...

unsigned char ItemName[16];

....

std::string cppString;

cppString = (const char *)ItemName;

 Memo1->AppendText(gcnew System::String(cppString.c_str()));  <=====
