There's no need to cast, AnsiString has a char* constructor and a char*
assignment operator. You can assign the char* to the Caption directly:
char* Buffer = "Your string 1";
Caption = Buffer;

Same here.

Of course you can. You have declared a char* pointer and you are assigning
it a hard-coded char* that resides in static memory. That is a perfectly
valid operation, it is not an error.
> You can use strcpy() or strncpy() later to initialize it
Only if you have allocated the memory for the buffer first.
