Loading a text file into memory

I was just wondering if I there was a way to load a file into memory where I could perform all file operations on it there and then save it back over the original file when I am ready. Is it possible to load a file to memory in VB and do something like this?
Thanks

you could load the complete file contents into a string:

Dim hfile as Integer
hfile = FreeFile
Dim strInput as string
Dim lLen as Long
Dim strfile as string
strfile = "c:\test.htm"
lLen = FileLen(strfile)
strInput = string(lLen, " ")
Open strfile for binary as #hfile len = lLen
get #hfile, , strInput
Close #hfile
Debug.print strInput



...and manipulate the string contents afterwards

Thanks...
