Vb .net - To Read Big Text File (1gb)

[loopz123]

HI ALL,

I AM DOING A PROJECT IN SEARCHING A STRING IN A BIG TEXT FILE(ie. 1GB). IT IS TAKING TOO MUCH TIME TO SEARCH AND WRITE IT INTO ANOTHER TEXT FILE.

I AM READING LINE BY LINE. I HAVE TO SEARCH FIVE STRING.

you can open the TXT file as Binary. then you put it into multi part (string) this means you should work with new functions... after all you join them in a string.
if you make the

Textbox.Visible = False

it'll be faster. after it opened it make it visible. ;)

The fastest code is:

FileOpen(1, "C:\test.txt", OpenMode.Input)
TextBox1.Text = InputString(1, FileLen("C:\test.txt"))
FileClose(1)
