Compare Operating System Version

Hi Kixtart Community

in our company do we use for a logon script kixtart.

I want make for the Windows 8 and later Users some changes different then the Windows 7 Users.

My Idea was like this.

 Code:
$osversion = @DOS
if $osversion >= 6.2
	? "Do something for Windows 8 and later."
else
	? "Do Something for Windows 7 and earlier."
endif


this compare doesn't work every time is this compare true.

When I set the variable "$osversion" for example
 Code:
$osversion = 5.2


I think the problem is something wrong with the data type that I get from the "@DOS" command.

Can you give me a tip to fix this problem.

regards

christian

Re: Compare Operating System Version

Kixtart is not strongly typed. Try adding in some error checking:

 Code:
if @DOS >= 6.2
   ? @SERROR
   ? "Do Windows 8 stuff"
else
   ? @SERROR
   ? "Do Windows 7 stuff"
endif

See what that gives you.

Try using this:
 Code:
$osversion = ReadValue("HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion","CurrentVersion")

Re: Compare Operating System Version

You can force a numeric compare with $Ver = Val(@DOS), or $Ver = 1.0 * @DOS.

In the second form, Kix sees a decimal number and converts the entire process to that format based on the first item referenced. Multiplying by 1.0 doesn't change the value but forces Kix to use precision math.

@DOS might return a version string, which will throw things off.

Re: Compare Operating System Version

Taking a minute to run "VarTypeName(@DOS)" confirms that it does return a string. This is the reason for inconsistent results. In my Universal Login Script, I have a global var that holds the OS Version as a number, available to other functions that might need it.

Re: Compare Operating System Version

Sorry with val it doesn't work too.

with the "1.0 *" I get just the first digit. i think this is a problem about the "," char. in Switzerland we have comma separated not with a point.

@arend

With your solution i have the same problem with "@DOS"

now I make the check with @PRODUCTTYPE

 Code:
if @PRODUCTTYPE == "Windows 7 Enterprise Edition"
	;? "Do Something for Windows 7"
else
	;? "Do something for other Windows"
endif


in this way I don' t have the flexibility with a numeric variable. but on this way I can make different between the Windows 7 and the others.

thanks for your help

regards

christian

Re: Compare Operating System Version

Please post your code for the 1.0* code, there is probably something amiss.

As for the other code, this will likely cover your bases a bit better.

 Code:
Select 
  Case instr(@producttype,"Windows 7")
    ;do stuff
  Case instr(@producttype,"Windows 8")
    ;do stuff
  Case 1
    ? "OS not covered"
Endselect

Re: Compare Operating System Version

Did you try 1,0 * @DOS? You need to be consistent with the regional settings.

The multiplication by 1 doesn't change the value, and specifying a decimal point forces the value to be a real number, not an integer.

Re: Compare Operating System Version

Personally I use code similar to Allen's:
 Code:
Select 
  Case Left(@ProductType,9) = "Windows 7"
    ;do stuff
  Case Left(@ProductType,9) = "Windows 8"
    ;do stuff
  Case Left(@ProductType,10) = "Windows 10"
    ;do stuff
  Case 1
    ? "OS not covered"
Endselect

Re: Compare Operating System Version

Thank you Alex.

Just so everyone knows, @dos indeed returns 10.0 on windows 10 but after some updates it can also return 6.1

this seems to have to do with windows 10 not guarding the value in:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion

where kix seems to get it. I have only seen this issue once and I believe it was after a .net installation/patch.
