Using Env. variables

[GEOSoft]

I am starting to convert some AutoIt 2 scripts to Auto it 3 and I am running into problems. If I use the following example it works.

$VN=RegRead ( "HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion", "versionnumber" )
MsgBox(4096,"" , "The Version Number is: "&$VN)
Exit

I want to declare

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion

as a variable (RegPath), but I can't get it to work right. I have to use that string several times in the script so hard-coding the path is not the greatest answer.

$mykey = "HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion"
$VN = RegRead ($mykey, "versionnumber")

Oh, and they are not Env variables in v3 they are internal AutoIt variables.

And I wouldn't go nuts converting large script, the syntax of v3 is ever changable until I release.

Thanks Jon.

That worked and while I was waiting I tried something else that also worked.

AutoItSetOption("ExpandEnvStrings", 1)
EnvSet ("Key","HKEY_LOCAL_MACHINE\")
EnvSet ( "RP", "Software\Microsoft\Windows\CurrentVersion" )
$VN=RegRead ( "%Key%%RP%", "versionnumber" )
MsgBox(4096,"" , "The Version Number is: "&$VN)
Exit

What are the pro's and con's of the two methods?

Also is it still \n for a new line in a message box?

I can understand that you will be making more changes yet but this at least gives me the practice with the new code and gives me a head start on the files. This particular script is quite long and has many things to convert. The reason I chose it for a starter is because it is the script that I needed a method to set defaults in the InputBoxes and ver.3 allows that. :-) Now I can get on to the part that converts that version number to a string that actually shows the Windows version being used. At one point (maybe in ver.2) I came across the code to return the version but it did not handle sub-versions. Windows 98SE was still reported as Windows 98. I seem to recall having the same problem with XP Pro and XP Home.

AutoItSetOption("ExpandEnvStrings", 1)

EnvSet ("Key","HKEY_LOCAL_MACHINE\")

EnvSet ( "RP", "Software\Microsoft\Windows\CurrentVersion" )

$VN=RegRead ( "%Key%%RP%", "versionnumber" )

MsgBox(4096,"" , "The Version Number is: "&$VN)

Exit

EnvSet seems to be just extra work to me

This should work as well

$Key="HKEY_LOCAL_MACHINE\"
$RP="Software\Microsoft\Windows\CurrentVersion"
$VN=RegRead ( $Key&$RP, "versionnumber" )
MsgBox(4096,"" , "The Version Number is: "&$VN)
Exit

Oh, I use the Line feed @LF

as in:

MsgBox(4096,"" , "The Version Number is: "&$VN & @LF & "Next line")

You can also use CHR(10) or CHR(13)

MsgBox(4096,"" , "The Version Number is: "&$VN & chr(10) & "Next line")

Don't use Env variables at all. Unless you want to retrieve "comspec" or "profile" or something like that.

Thanks scriptkitty, that worked just fine.
