$test contains a number but won't Hex

[Morthawt]

I have numbers going into a $test2 variable and I am trying to send it to a 2 byte hex like FF. If I let it run as part of the script it fails and does not return a value. If I manually set the value right before like $test2 = 65 then it works, but even though the value already is supposed to be 65 it does not work.. any idea?

For $a = 1 To StringLen($bitbuffer) Step 8

$base = 128
$chunk = StringMid($bitbuffer, $a, 8)
ConsoleWrite($chunk & @CRLF)
$temp2 = 0
For $b = 1 To 8
If StringMid($chunk, $b, 1) = '1' Then $temp2 += $base
$base /= 2
Next
;~ $temp2 = 65
ConsoleWrite('temp:' & $temp2 & @CRLF)
$binary &= Hex($temp2, 2)
ConsoleWrite('debug:' & Hex($temp2, 2) & @CRLF)
Next

If I uncomment out that line "$temp2 = 65" then every line shows the hex "41" but if I remove it it just shows 00 regardless.

What am I missing?

[Morthawt]

Here is what I see when I try and hex a value of 65 that gets generated. This is what Hex( throws out when I remove the parameter and just only have the variable in there:

4050400000000000

What on earth is causing that?

[BrewManNH]

You'd be better off treating the Hex as a string and using StringLeft/Right/Mid to get what you want from it.

[Morthawt]

I don't know what you mean? I only need to turn numbers like 65 into hex like 41 or 255 to FF etc. I have not had this issue using it before. If I specify $test2 with a value SPECIFICALLY like 65 then it works fine. However since I am doing math it seems to be failing on it even though its the same number ?!

EDIT:

I need this to work already, so I am going to post my whole source code even though its not ready yet. Line 186 should be showing hex like FF AC 41 or what ever but it only ever shows up 00. Even if you remove the ", 2" you see just weird crazy stuff that should not be there. I have tried adding all kinds of debugging code to try and figure it out, consolewrites galore but I cannot figure it out.

Do you know what's the difference between integer and double-precision number?

Local $iInteger = 10
Local $fDouble = 2 * $iInteger / 2

ConsoleWrite("Integer, value = " & $iInteger & ", Hex representation = " & Hex($iInteger) & @CRLF)
ConsoleWrite("Double, value = " & $fDouble & ", Hex representation = " & Hex($fDouble) & @CRLF)

You are seeing just that. Both numbers are 10, but former is integer and latter is not. Your mathematical operation changed the type of the variable. If you want your number to be integer then you have to Int() it. Hex() shows binary representation of the number which is exactly how it's stored in memory of your computer.

ah thanks

Use varGetType to check the type of a variable:

Local $iInteger = 10
Local $fDouble = 2 * $iInteger / 2

ConsoleWrite("Integer, value = " & $iInteger & ", Hex representation = " & Hex($iInteger) & @CRLF)
ConsoleWrite("Double, value = " & $fDouble & ", Hex representation = " & Hex($fDouble) & @CRLF)

ConsoleWrite("VarGetType($iInteger): " & VarGetType($iInteger) & @LF)
ConsoleWrite("VarGetType($fDouble): " & VarGetType($fDouble) & @LF)

[Morthawt]

Thanks, that was driving me crazy. Before I had one line setting the initial value, one line making the change needed and one line dividing the first initial value by 2 so it went smoothly down. After 3 hours of being totally stumped I ended up having a switch that has 8 cases. Is there any benefit with this double-precision? I mean a number is a number, I checked it a million different ways, same string length, is a digit, is a number, it would add and subtract to different values etc. So what is the purpose behind a double-precision ?

[water]

Wikipedia tells you.

[Morthawt]

Thanks, well I dealt with that issue so the only one remaining is this. I am trying to convert typed text or files to base64 and am having some issues with unicode vs ascii or what ever. If I leave the stringtobinary at 1 parameter than I can encode and decode an exe file perfectly. However when I then convert a file containing chinese letters or what ever it messes up.

When I read the file as UTF-8 and encode the file the exe looks wrong right from the start. Even online converters where I have converted exe's always have the encoded part at the start as "TVqQ" and when I encode the exe after swapping to binary UTF mode is "TVrC". So my script is not doing something correctly or something. I figured if I use unicode for everything to do with my conversion that it would just be universal and work with everything. Any chance you could have a quick look at my script and see if anything jumps out at you? For your own testing pick any old exe and put it on the desktop and alter the file name of it at the top of the script so it loads your exe because I am using a 13kb file from www.grc.com because this program is very slow for encoding big files.

Oh and by the way, I included an easy to locate variable near the top which you can 1 or 0 to go back and forth from the normal stringtobinary vs the UTF one.

[Morthawt]

Ok, I rewrote the entire thing and it is a lot cleaner code and I think it works better. My issue is with decoding a previously encoded UTF-8 file.. I can type UTF things into the text area on the GUI and it decodes fine, however when I try and decode a correctly encoded file it ends up missing those UTF characters and instead only seeing "?".

Could someone have a quick look through my code and see if anything jumps out at you? It has to be something to do with the writing to file part because as I said it works fine for text in the box, decode it and boom... you see all the wacky UTF symbols etc perfectly in there.

I got it working. I have been bounding ideas around with a friend. It turned out I needed to treat file encoding differently because there is raw hex bits (binary) to work with. The typing into the box part I have all in UTF-8 now and it works flawlessly. I will paste it here. It is a lot better code than any of the other 4 versions I have coded. I would welcome some feedback on the methodology I have used etc.
