searching a file for a text

[DaZZleD]

Hi.

I'm trying to read the contents of a file (which could have around 2-3Mbs - it's in binary format) and search for a pattern. I have to use Regular expressions so I got a free component that can search a string using regular expressions. How do I get the contents of the file into an WideString or ... if anyone has a better idea...

Thanks

I often load text files into a TRichEdit component, and use its FindText method to locate text. However, I'm not sure whether it would be able to handle a text file as big as yours!

Hope this helps!

i managed to use a TMemoryStream to read the file and replace all #0 characters (this allows me to use all the output as one string). Then using regular expressions I managed to do this in under 0.3 seconds
