C / C++ / MFC

1. Is this a debug or release build
2. Are you running the application under VS2005 when you get the 26MB memory usage

1. I would (pretty much always) hold the data separate from the list control (using the LVS_OWNERDATA[^] style). That way you compare data using some container (STL rather than MFC, please, for me) which will be much quicker than by putting the data in the list control.
2. As the second column is sorted, you can search through it using a binary search[^], which the STL has built-in....although you want to use lower_bound[^] rather than the more obvious binary_search[^]

in code there is a msg

"pls input the directory or path where you save the file"

Rather than having numbers in the xml file, I wanted to include the enum symbols itself(strings) which is readable and self explainatery in the xml file.
