hi,

i was trying to read the text/string from an ini file and i want to put it in textBox1->Text
i did some research and tried these

void MarshalString ( System::String^ s, std::string& os )
{   
using namespace System::Runtime::InteropServices;   
const char* chars = (const char*)(Marshal::StringToHGlobalAnsi(s)).ToPointer();   
os = chars;   
Marshal::FreeHGlobal(IntPtr((void*)chars));
}


button1:
.....
string std_string = pt.get<std::string>("Section1.Value1");
String^ str = "";
				 
MarshalString(str, std_string);
textBox1->Text = str;


but it gives me this error:
Additional information: External component has thrown an exception.


any better ways to do it? thank you in advance

This is a conversion std:string to w_char[] to System.String. Could also be a case of a string compiled as non-Unicode. Basically, this is the answer. My 5.

Agree ;)
   
Would you post it as the answer, just to close the question?

Code looks OK, but - probably - textBox1 is throwing an exception.
