QuoteOriginally posted by: HansiRealistically SSIS would only be beneficial if this is going to end up in a MSSQL db.You are usually spot on Hansi but this I do not capish. You can use SSIS to write output to just about any database, Excel, or even csv files.

Put "realistically" (not sure if it's the right phrase to use here) because there are generally faster methods to use if you are using other databases. SSIS to MySQL was dead slow when I tried using it last time but that was a few years ago.

Maybe M$ intentionally made their driver slow for that, although I have to say I'm not very impressed by MySQL in general. If you want a free database, PostgreSQL is a far better product, IMHO.

QuoteOriginally posted by: edouardthis is a C++ exercise. i would appreciate hints.let's say i have annual OLHC files for several underyings. the files are the locate in the same directory.cac402008.txt,dji2008.txt,goog2008.txtcac402007.txt,dji2007.txt,goog2007.txt....i want to concatenate the files to get long term time series of each underlyingfor file/path manipulations, some seem to recommend boost.filesystem. is that a good idea ?

Well I'll be the son of a monkey's uncle. Somebody on Wilmott that answers the actual question someone asks. You are my new hero, nosbor.

Here is the C version.perhaps you should make it "static void concatenate()"

Quoteperhaps you should make it "static void concatenate()"Good point. This example shows why C++ is a better C.
