replace object property with array value

[jefhal 2]

Is there a way to use an array value in place of an actual property name in a script? I have 10 properties that I want to read and I've stored them in an array called: $Property.

Now I want to loop through a for/next loop and display each of the properties as shown below:

$Property = _ArrayCreate("property1", "property2", "property3")
$oId3 = ObjCreate("CDDBControl.CddbID3Tag")
for $i = 0 to UBound($Property)
    $fld = $oId3.$Property[$i]
    msgbox(1,"Property=",$fld)
next

When I do it now, I get: ERROR: syntax error

$fld = $oId3.$Fields

I also tried $old3. & $Fields[$i] and a few different cases with quotes. Still no luck.

I dont know but I think you might be looking for

$old3.$Fields[$i] = $Property[$i]

Maybe answer? Sorry if it's not I havn't played with COM all that much yet.

Shesh... you're making my head hurt...

How about this:

for $i = 0 to UBound($Property) - 1
    $fld = Eval("$oId3." & $Property[$i])
    msgbox(1,"Property=",$fld)
next

Note the Eval and the "- 1" on the For loop.

My head already hurts. I tried your suggestion, but it appears that $oID. has to be followed by the literal property or method rather than a "stand-in". Maybe someone else out there knows of a "trick" to make it work. I'll keep trying, and I can always do it the long way which results in 12 times as much code...

$old3.$Fields[$i] = $Property[$i]

Well, unfortunately, the values in $Fields are more like "red", "blue", "green". That is, they are not predictable, so they themselves can't be incremented...

I thought I remembered answering this question before -- sorry, it is execute, not eval you want to use. See here: Using variables with COM manipulation?

You got it! That worked great. Thank you...
