Strings are a maximum of 255 bytes long (plus one byte for the length). In memory, they use 256 bytes whatever length is used. You could use a string array to hold a number of records before saving. Each array element would use 256 bytes so there will be a limit to the size of the array (depending on your memory usage). Jim VK7JH MMedit |
