Getting a std string into a String^

[ac251404]

Hi, I am trying to set the text of a textbox but textboxes only take String^ not std::string. I have a function to change a String^ into a std::string but not vice versa. According to this you can simply do: String^ s = somestring.c_str(). Here is my code followed by the error.

String ^rd;
std::string read;

read = "abcd";
rd = read.c_str();

error:

c:\documents and settings\ac251404\my documents\visual studio 2005\projects\project1\project1\Form1.h(590) : error C2440: '=' : cannot convert from 'const char *' to 'System::String ^'
        No user-defined-conversion operator available, or
        Cannot convert an unmanaged type to a managed type

PS - using visual c++ 2005 express

Thanks!

You could try the following, although I haven't tested:

rd = Marshal::PtrToStringAnsi(read.c_str());

I got it working with the following:

rd = gcnew String(read.c_str());
