about registry string values

[pipiboy]

Registry content:

Name | Type | Date

=============================

TestKeyA | REG_SZ | 5.5.5.5555

TestKeyB | REG_SZ | 3.3.3.3333

=============================

Code：

$var1 = RegRead("HKEY_LOCAL_MACHINE\SOFTWARE", "TestKeyA")

$var2 = RegRead("HKEY_LOCAL_MACHINE\SOFTWARE", "TestKeyB")

;$Result = Number($var1) - Number($var2)

;MsgBox(4096, "result:",$Result) ; Result = 2.2

=============================

But I need this value(2.2.2.2222):

Var1(5.5.5.5555) - Var2(3.3.3.3333) = Result (2.2.2.2222)

Please kindly help me with this situation,ths!

REG_SZ is a string value - so you can't do a simple arithmetic operation on it. Use StringSplit with "." as separator, do your arithmetic on every item in the returned array and then us a _ArrayToString to create a string again.
