Hi all,

I have one windows service made in C#. I want My service to create CSV file every two minutes... but it should overwrite the existing file every two minutes. but whenever I try - it says file is already open - while I am sure that file is processed during those elapsed two minutes.. How do i programmatically close the file or overwrite the same. My file creation is through windows utility CSVDE (so have no control over creation except for the time and name!)

please suggest, thanks,
Jeet

I think you forgot to close the stream or something like that if you send the code, maybe i can have better ideas.

A simple google search [^]gave me these reults.

And the first one [^]seems to answer your questions.

dvs.RowFilter = Name Like '%Book%' AND Name like '%this is%'

Another options is that, use the CopyTo method of the dataview after the fisrt operation and now use this datatable to filter the results for the next datagridview

What you already done for this, if you don't know how to retrieve data from database, just buy a book and go through it.

I just give some hits to retrieve data from database for searching

1.write a sql query for searching
2.Execute with sqldatareader or dataset
3.display the result using grid view.

Use Regular expression like

Hi
If you want to present the graphs online (and this is a .net forum) I would say use ASP.NET. You could preprocess the incoming data, so that not every request triggers the redraw of your graph.
