Transformation Error. I can not output a variable in TextBox Read more: http://forum

Thank U. I decided this problem

std::string str;
 
                 const char* temp = (const char*)(System::Runtime::InteropServices::Marshal::StringToHGlobalAnsi(textBox1->Text)).ToPointer();
                 str = temp;
                 System::Runtime::InteropServices::Marshal::FreeHGlobal(IntPtr((void*)temp));
 
                 textBox2->Text = gcnew String(str.c_str() );

(sorry for the smiley overkill... )

This crude mix of managed and native code is by far the creepiest example of that "technique" I've ever seen!

And it's functionally exactly equivalent to this:

textBox2->Text = textBox1->Text;

You'd probably have been much quicker simply looking up the correct C++/CLI syntax for working with reference types like System::String than digging out all that (in this context absolutely counter-productive) interop stuff.
