I wrote a Windows Form Application which should read a log text file, while it is being written from other application ¿ This other application in every 10-100 sec. add a row to this text file. I have no idea what access mode this other application use with the file, but I guess it open the file with add mode, wrote new lines info and then close the file open pointer. It is on C++ or Deplhi
So I’m wondering what is my best tactics? I guess it is better I to read all the file at once, to close it and then to start cycle between its line and add my logic.
Or it will be better first to copy the file on other direction on HDD and then to read this copied file?
The text file I should read is with 200-2000 lines, not so good as every day it create a new one.
Second question – I plan to use StreamReader , this is the right choice? I need .NET library which read the text files without being locked it at all. I wrote in my DB which is the last row I have been read, so my only problem is to NOT block the other application access.
