[Solved] Help getting getText() into System::String^

[jimburnettva]

I'm tired and maybe someone else can see something I'm missing.



/* This doesnt work. */
core::stringw pname =txtID->getText();
std::stringstream ss;
ss << pname.c_str() << endl;



/*

*/

cli::array<Byte>^sendBytes = Encoding::ASCII->GetBytes( ss.str() + "," + ship->getPosition().X + "," + ship->getPosition().Y + "," + ship->getPosition().Z );
udpClient->Send( sendBytes, sendBytes->Length );

This puts the pointer address in ss which is probably not what you want.

Code: Select all

core::stringw pname =txtID->getText();
std::stringstream ss; 
ss << pname.c_str() << endl;

this works:

Code: Select all

  IGUIStaticText * text = guienv->addStaticText(L"Test", recti(0,0,0,0));

  std::string a = core::stringc( text->getText() ).c_str();

  std::stringstream ss;

  ss << a.c_str() << std::endl;

  std::cout << ss.str();

I still get the same errors with:


std::string a = core::stringc( txtID->getText() ).c_str();
std::stringstream ss;
ss << a.c_str() << std::endl;
cli::array<Byte>^sendBytes = Encoding::ASCII->GetBytes( ss.str() + "," + ship->getPosition().X + "," + ship->getPosition().Y + "," + ship->getPosition().Z );
udpClient->Send( sendBytes, sendBytes->Length );

i'm trying to convert getText to type "T"

Such as this (but this doesn't worky)


template <class T>
T getName (std::stringstream ss)
{
T result;
result = ss.string();
return (result);
}

[jimburnettva]

Figured it out.


std::string a = core::stringc( txtID->getText() ).c_str();
String^ s = gcnew String(a.c_str());


Works like a charm!
