Use this member function to write data from a buffer to the file associated with the CArchive object.
Specifies a pointer to a buffer containing a null-terminated text string.
The terminating null character ('\0') is not written to the file; nor is a newline automatically written.
WriteString throws an exception in response to several conditions, including the disk-full condition.
Write is also available, but rather than terminating on a null character, it writes the requested number of bytes to the file.
CFile myFile("myfile", CFile::modeCreate | CFile::modeReadWrite); CString str1="String1", str2="String2", str; // Create a storing archive. CArchive arStore(&myFile, CArchive::store); // Write str1 and str2 to the archive arStore.WriteString( str1 ); arStore.WriteString( "\n" ); arStore.WriteString( str2 ); arStore.WriteString( "\n" ); // Close the storing archive arStore.Close(); // Create a loading archive. myFile.SeekToBegin(); CArchive arLoad(&myFile, CArchive::load); // Verify the two strings are in the archive. arLoad.ReadString( str ); ASSERT( str == str1 ); arLoad.ReadString( str ); ASSERT( str == str2 );
