Length of text file

[rewdee]

I have to read a large (10,000 to 40,000 rows) CSV file into a stringGrid (I am using a component that will do the grouping).

I would like to show a progress bar or gauge to show the process of loading. Does anyone know how I can get the total number of rows in the file so I can write a new LoadFromFile procedure?

Thanks,
Rewdee

I've never found a way other than to run through the file and count them, then reset it to the top. Since a text file doesn't have fixed length lines, you basically have to read to all of the CR/LF's before you can know how many lines are in the file.

Hi Rewdee
It might be posible to use the 'filesize' function to get the file lenght and use this to set the limits for your gauge, I don't know how sucessful this would be.
