[SOLVED] Integer/hexadecimal/binary to string

6 posts in this topic

#1 ·  Posted (edited)

Hello everybody,

I have couple characters, they are A, B, C. They are converted to hexadecimal numbers: 41, 42, 43.

ABC(string) = 414243(hex) = 4276803(dec)

I want to convert for example 4276803 to string like ABC and opposite.

Sorry for my bad English. :(

 

EDIT: I found Chr and Asc functions, they are made only for characters, I need functions that would be for strings.

Things aren't that simple. Look at what gives a naive approach:

Local $n = 4276803
ConsoleWrite(BinaryToString($n))
ConsoleWrite(@LF)
Local $s = "ABCdef"
ConsoleWrite(StringToBinary($s) & @LF)

Windows platforms are little-endian, which means that integers (for instance) are stored with low-order bytes first. That's why your 4276803 value gets interpreted as "CBA".

See the difference here:

Local $n = 4276803
ConsoleWrite(Hex($n) & @LF)
ConsoleWrite(Binary($n) & @LF)

If you intend to thusly process random strings then you'll have to process them in a loop, character by character. StringToASCIIArray and StringFromASCIIArray will help then.

Using the AutoIT help tool, you can easily find : BinaryToString() :

Remarks

Unlike String() which returns a hexadecimal representation of binary data, this function will assume the binary data is a string value and convert it appropriately.
See "Unicode Support" for a detailed description.

Maybe you could read my post above to understand why this doesn't work.

@jchd - well, well, well

Maybe have a look on timestamps for your answer and mine to avoid posting such remarks ...

But I agree with you, this is not so simple ...

I closely look and ... see nothing deserving what you say.

Also it isn't too late to edit your misleading advice.
