I need to write a file on the HDD something like C:\myFile.txt from VBA (including the creation of the file if it does not exist) and than to read the content of this file from VBA. I know how to do this in other languages like C++ or Java, but I don't know if this can be done from within MS Access. Can you help me, please?

Yes, this can be done as well. I parse data from a txt file into one of my apps. This is a lot of code, but it is showing how to check for the file, then open it for reading, then overwriting it with a blank copy (so data is not imported twice). Try this:

HTH

BTW, I haven't gotten around to moving the connection info off the loop, so it is opened and closed on each loop. That adds time. YOu can move the connection info before the loop to save time.

That sounds much more complicated than something along the lines of:

Thank's a lot.
