Description
Returns a pointer to the underlying string data.
data returns a pointer to a null-terminated character array that the AnsiStringT uses to store its value. This is the same value as the one returned by the c_str method, except that data returns a NULL pointer when the value is an empty string.
Note: Because data returns NULL instead of an empty string, it is useful for C++ functions that expect either a valid (non-empty) char* or NULL. The following example assumes that TCHAR mapping is not set to wchar_t:
AnsiString x; ShellExecute(0, static_cast<const char*>(x.data()), "File.txt", NULL, NULL, SW_SHOW);
If TCHAR mapping is set to wchar_t, ShellExecute becomes the wide version, ShellExecuteW. If you want to use the Ansi version of ShellExecute when TCHAR mapping is set to wchar_t, you should specify ShellExecuteA.
