DLL or Plaintext?

[ina]

Need your advise.

If I have many data (million) and I want to put them in external file. What should it be? A DLL file (the data will store in array) or just store it in plaintext?

I want the program can find the data very fast in external file and of course the memory consumtion is small. I dont want to use Access and so on or any runtime file.

if you don't use a database,you lost many power of searching,inserting and etc.
however if you store data in the array in the dll you need a lot of memory.
if you search on the Internet,you will find lite databases that can work without any driver.

I just need searching operation so I think database in not needed..

btw I found quick sort and binary search to search faster in array, but yes the proble is the memory is still big.

Perhaps you can use CreateFileMapping() and MapViewOfFile() to load it into memory?
