[Solved] Variable returning unexpected result (Can't append value to variable)

[EmilyLove]

So here's the script

$sBinaryVideoPath = RegRead("HKEY_CURRENT_USER\SOFTWARE\NVIDIA Corporation\Global\ShadowPlay\NVSPCAPS", "DefaultPathW") ;Value = 0x43003A005C00550073006500720073005C0062006500740061006C005C004F006E006500440072006900760065005C0044006F00630075006D0065006E00740073005C0056006900640065006F0073000000
$sVideoPath = BinaryToString($sBinaryVideoPath, 2)
$sVideoPath &= "\TEST"
InputBox("","",$sVideoPath)

This gets the folder that Nvidia ShadowPlay saves its videos to. Don't worry if you don't have ShadowPlay Installed, just replace $sBinaryVideoPath with the commented value.

Then it converts the binary string to a regular string so we can read and use it.

Then I append "\TEST" to the end of that string.

Finally I display the variable.

 

The problem is it won't append anything to the end of the variable once it is assigned. I can prepend something to this string but appending fails for some reason. Can someone help me figure out this issue?

BinaryToString is leaving the null character on the end of the path, you'll have to strip it away.
 

$sBinaryVideoPath = RegRead("HKEY_CURRENT_USER\SOFTWARE\NVIDIA Corporation\Global\ShadowPlay\NVSPCAPS", "DefaultPathW")
$sVideoPath = BinaryToString($sBinaryVideoPath, 2)
$sVideoPath = StringStripWS($sVideoPath, 2)
$sVideoPath &= "\TEST"
InputBox("","",$sVideoPath)

The last character is the string is Hex 00, so you need to strip that:

$sBinaryVideoPath = Binary("0x43003A005C00550073006500720073005C0062006500740061006C005C004F006E006500440072006900760065005C0044006F00630075006D0065006E00740073005C0056006900640065006F0073000000")
$sVideoPath = BinaryToString($sBinaryVideoPath, 2)
$sVideoPath = StringTrimRight($sVideoPath, 1)
$sVideoPath &= "\TEST"
ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') : $sVideoPath = ' & $sVideoPath & @CRLF & '>Error code: ' & @error & @CRLF) ;### Debug Console

Got it. Thanks everyone.
