Question:

I am trying to convert a String to char* but keep receiving
the error:
          \"Cannot cast from System::AnsiString to Char*\". 

Below is my code.  What am I doing wrong?
        String s;
        char* ch;
        s = \"test\";
        ch = PChar(s);

Answer:


What you need to do is use the c_str() member function of
AnsiString. Here are a couple examples:

        String s;
        const char* ch;
        s = \"test\";
        ch = PChar(s.c_str());

You can avoid the PChar completely if you like.

        String s;
        const char* ch;
        s = \"test\";
        ch = s.c_str();

Simpelt ...

FRA ch(char * el. char[]) TIL st(AnsiString):

st = ch;

FRA st(AnsiString) TIL ch(char * el. char[])

strcpy(ch, st.c_str());

Tak skal I have. Det var lige det jeg skulle bruge - I kommer vist til at deles om pointene.
