stringtobinary - write to txt file

15 posts in this topic

Hi this code uses stringtobinary just fine with the msgbox, but won't write the binary numbers to my txt file (kb.txt)

$read = FileRead(@scriptdir & "\test.txt")
$file = (@ScriptDir & "\kb.txt")

$buffer = StringToBinary($read)
MsgBox(4096, "String() representation" , $buffer)

FileWrite($file, $buffer)

someone knows why? :)

Does it work if you change the last line to:

FileWrite(@ScriptDir & "kb.txt", $buffer)

No, it writes The content from test.txt to kb.txt but stringtobinary, does not have any effect ón it

Of course it's a no-op in this case: you're writing exactly the same content that you just read.

Make $buffer a string before final write:

FileWrite($file, $buffer & '')

Something to take care of: your output file will have the '0x' prefix prepended, which you may want to remove before writing:

FileWrite($file, StringTrimLeft($buffer & '', 2))

EDIT: also take care of selecting the character encoding that will suit your use!

Something like:

FileWrite($file, StringRegExpReplace($buffer & '', '(?:0x)?([[:xdigit:]]{2})', '1 '))

thanks :)

with this:

$read = FileRead(@scriptdir & "test.txt")
$file = (@ScriptDir & "kb.txt")

$buffer = StringToBinary($read)


[code]$read = FileRead(@scriptdir & "test.txt")
$file = (@ScriptDir & "kb.txt")

$buffer = StringToBinary($read)

FileWrite($file, StringTrimLeft($buffer & '', 2))

how would i get it back to normal? I tried to do BinaryToString, instead of StringToBinary

Back to normal? What do you revert back to "normal"?

legend,

Your source file "test.txt" is still there, yes? Is that what you mean by "back to normal"?

FileWrite($file, StringTrimLeft($buffer & '', 2))

legend,

If you are looking for encryp/decrypt routines, there are UDF's for that.
