Crearing File: Specific byte

Recommended Posts

GajjarTejas

I'm creating file in autoit just 10 byte but FileWrite Function create 40 bytes file.Below is my script.Where is error in my script? Also I can't create 1 or 2 byte file.

FileDelete("File.bin") ;Delete Previous File if Exists
For $i = 1 To 10
$file = FileOpen("File.bin", 19) ;Open File File.bin if Not Exists Then Create It
FileWrite($file, 0x41) ;Write 0x41 (only 1 Byte) To File File.bin
FileClose($file)
Next

@GajjarTejas

Even in notepad it is 40bytes.

And in 0x41 - 4characters. - 4 bytes x 10times = 40 bytes

If you trying another number base system den u need to convert by some function

Why are you opening the file inside the loop?

Also, you need to cast to binary like this:

;FileDelete("File.bin") ;Delete Previous File if Exists
; File is truncated to zero by the 2 flag in FileOpen.
$file = FileOpen("File.bin", 18) ; 2 + 16 = Create empty + Binary mode.
For $i = 1 To 10
    FileWrite($file, Binary('0x41')) ;Write 0x41 (only 1 Byte) To File File.bin
Next
FileClose($file)

Why not look at

AutoIt Code:

_DummyFile(@ScriptDir & "Test.txt", 30)

Func _DummyFile($sFilePath, $iSizeMB)
    Local $hFileOpen = FileOpen($sFilePath, 18)
    If $hFileOpen = -1 Then
        Return SetError(1, 0, 0)
    EndIf
    FileSetPos($hFileOpen, $iSizeMB * 1048576 - 4, 0)
    FileWrite($hFileOpen, 0)
    Return FileClose($hFileOpen)
EndFunc   ;==>_DummyFile
