VBA: Filter the datas to export from Data Provider

[Benouche]

Hello,

I'd like to thanks everyone in this helpful forum for providing good advice and help.

my problem is the following:

I want to export periodically new datas from a report to a unique text file (file1).
To achieve this task, I need to control which information have already been exported and which is a new one.
For this I keep in another text file (file2) the summary of present data in file1.

My question is : how can I filter the data I want to export from the Data Provider (filter based on DP infos and file2).

Thanks in advance,

Benouche
