That's true. BUT... $strA will now ALSO have the value "Hello World!" Great tutorial, tho! What you want is $strC = $strA + $strB. Additional comment:

You say that
$strC = $strA += $strB
will cause $strC to have the value “Hello World!”

That’s true.

BUT… $strA will now ALSO have the value “Hello World!”

Great tutorial, tho!
What you want is $strC = $strA + $strB.

In your string concatenation example of $strC = $strA += $strB, you correctly state that the value of $strC is the concatenation of strings $strA and $strB. However, the += operator is not the same as the + operator. The += operator will concatenate the operand on the left side with the operand on the right and store the result in the operand on the left. A += B is shorthand for A = A + B. So in this example, after the operation, $strA also contains the concatenation of $strA and $strB. Similarly, A -= B is shorthand for A = A - B.

only comes out equal to 6 if you declare the variable as an integer
[int]$x = …

otherwise you get:

$x = 5.66666666666667

Good catch Lawson. I am launching WMI part 3 tutorial tomorrow 3/19. I am looking to start ADSI next week, so look for it. Ooooppps! Good catch Lawson.

You left of the double-quotes. When do you plan to post the ADSI training session? Keep up the good work. In your answers you have $strComputer = FSrv01 should it not be $strComputer = “FSrv01″.
