# Converting exported binary reg values into strings?

## Recommended Posts

I've written a program that automatically converts a registry export file (.reg) into an AutoIT script for easy import into an existing AutoIT program. The exported binary values are listed like ... "hex:31,32,33,34,80,ff" for their string equivalent of "1234" + chr(128) + chr(255). I need to convert this binary data into string.

I'm sure this is a long shot, but ... Does AutoIT have a way to internally convert a binary registry value into its string equivalent? I'm not asking for a bunch of code. I'm just wondering if AutoIT has it built in.

```\$bData = '0x3132333480ff'
MsgBox(0,'test',BinaryToString(\$bData))```

Ok, my next issue ... Due to the fact that the output from my program is saved to a file, and must be user-readable, and that not all binary/expanded binary values are user readable, I've set up my program to create a string of chrs like such:

Binary: chr(49) & chr(50) & chr(51) & chr(52) & chr(128) & chr(255)

MultiString: chr(49) & chr(0) & chr(50) & chr(0) & chr(51) & chr(0) & chr(52) & chr(0) & chr(172) & chr(32) & chr(255) & chr(0) & chr(0) & chr(0) & chr(0) & chr(0)

ExpandedString: chr(49) & chr(0) & chr(50) & chr(0) & chr(51) & chr(0) & chr(52) & chr(0) & chr(172) & chr(32) & chr(255) & chr(0) & chr(0) & chr(0)

I think my Binary conversion is correct. But the Multi and Expanded strings are still problematic, as they have 2 values. For instance, decimal 172 and 32 somehow are calculated to create chr(128). Can someone explain how this is calculated?

Edit: for clarification ...

The values I saved to Registry were "1234" +chr(128)+chr(255).

The data saved in the chr(128) position for Expanded and Multi strings is "AC 20", which when pulled from the registry and converted to decimal are "172 and 32". So I need to understand how I can calculate these values to equal back to 128.

Another edit ...

Here is the function I wrote to convert the information pulled from the registry export file. \$BinaryData is the value data exactly as it was extracted from the file. e.g.:

31,32,33,34,80,ff for Binary (which works fine)

31,00,32,00,33,00,34,00,ac,20,ff,00,00,00 for ExString (which has 2 values for each character).

```func ConvertBinaryToStringOfChrs(\$BinaryData)
\$BinaryValues = stringsplit(\$BinaryData,",")
\$BinaryData = ""
if \$BinaryValues[0] > 0 Then
for \$intA = 1 to \$BinaryValues[0]
\$BinaryData = \$BinaryData & "chr(" & dec(\$BinaryValues[\$intA]) & ") & "
Next
\$BinaryData = stringleft(\$BinaryData,stringlen(\$BinaryData)-3) ;remove trailing " & "
EndIf
return \$BinaryData
EndFunc```

I realize the function is not yet working for multi character conversion, but that's not the issue. I just need to understand how I can combine the 2 characters for ExString into one correct value.

Those binary strings are Unicode UTF-8. Lookup BinaryToString parameters to convert them correctly in all cases.
