reading one character from a file at a time

i wish to open a file in binary mode (so i can read each character at a time, including EOF, CR, LF etc) using a Do Until EOF loop.
i think i am supposed to use GET but i am not sure how to read a single character, i can read the whole file at once, but this is not what i want to do. thanks in advance

Reading the whole file then using a string function would be faster i.e.

Code:

---

'LoadFile here
TheFileContents = 'What's in the file
For x = 1 to len(TheFileContent)
TheChr = mid$(TheFileContent,x,1)
'Things you want to do with this character
Next x

---

Hope I helped,

sorry, i didnt explain why i cant do that, i have to do it one byte at a time.. because i will be reading large files (ie > 50 MB) and these will not all fit into one string, they may fit in a variant but i am not willing to use all the ram that way ;)

You could declare a user defined type of one string character

Code:

---

Type OneChar
  OneByte  As    String  * 1
End Type

---

Then you could open the file for random and access it one character at a time:

Code:

---

Dim iChar As OneChar
Dim iFileNum As Integer
Dim iRecLength As Long
Dim iLastRec As Long

iRecLength = Len(iChar)
iFileNum = FreeFile
Open "yourfile.txt" For Random As iFileNum Len = iRecLength
iLastRec = FileLen("yourfile.txt") / iRecLength

---

Then you loop through the records(actually characters) using the Get Statement.

Code:

---

For x = 1 To iLastRec
  Get #iFleNum, x, iChar
Next x

---

Hope that works..

will that method work with binary access? because if i open it with random i will not be able to read EOF, of which there will be several scattered through the file.

tried to do a

Code:

---

Dim MyVar as OneByte

---

didnt work ;P
