Hi experts..
I have a VB.NET application which imports a few csv files into a database nightly..
I need to ascertain if the file has changed from the previous nights import before I decide to import it or not.
I thought the easiest way would be to hash the file and store this hash in a table.
Then, each subsequent nightly import, I would simply hash the file, compare it with the hash of the file uploaded the previous night, if the hash's match, do nothing, if the hash's are different, perform the import..
So, can anyone poiont me in the right direction for hashing a file with VB.NET please??
Thanks in advance.
