copying text box entry to char array

[raydona]

Hi, How do I assign the characters entered into a text box to a c-style character array? I have to do this because the library I'm using contains many functions whose parameters are c-style character arrays. I wish to say something like:
char* x = new char[20];
strcpy(x, textbox->text);

Well you should find out the size of textbox->text first by using the strlen() function and allocate that size + 1.
But I'd rather use std::string or std::vector<char> rather than a char array. You can still pass a c-style string to those functions with a std::string (with the c_str() member) or std::vector<char> (by making sure it's nul terminated and passing v[0] to it).
