question on logiclib
i have:
...
var Var1
var Var2
...
${If} $Var1 <> $Var2
; do action 1...
${Else}
; do action 2...
${EndIf}

When values are different i expect 'action 1' being executed but this never happens. for example:
Var1 = "1.3.1.0"
Var2 = "1.4.1.0"

i'm getting 'action 2' executed. Why ?

thanks.

ps. not yet tried with latest version of logiclib (just downloaded). Now using lib which comes with nsis 2.06.

Please give amore complete example what you do e.g. how do you assign the values to Var1 and 2

surly NOT with :

Var1 = "1.3.4.5"

because that will not work ;)

If you want compare 2 versions use "VersionCompare" scripts. Search for forum and NSIS Archive.
For example this link.

found why
thanks for the two replies: paying more attention at logiclib.nsh description i understood my error was not to use the right comparison command:
<> for signed integer tests (built-in);
!= for string tests (built-in);
S!= for case-sensitive string tests (using System.dll);
S> for case-insensitive string tests (using System.dll)
and so on...

So the right working code becomes:

${If} $Var1 S> $Var2 ; (or $Var1 != $Var2 if i want to check just differences)
; do action 1...
${Else}
; do action 2...
${EndIf}

And about versions compare, specific UDFs maybe fine but logiclib, when used properly, could be just enough in most cases.

thanks.
