issue reading "default key" from registry with WMI

[ripdad]

A direct approach might be better than that dirty work-around.

If $sSearchValue == '' Then
    Local $str
    Local $err = $objReg.GetStringValue($nHKEY, $sRegKeyPath, '', $str)
    If $err Or Not StringLen($str) Then Return ''
    Return $str
EndIf

BrewManNH,

hmm, on that last one I get:

-1.#IND

Hi ripdad,

already thought to this kind of approach,

but it's a "brute force" reading with the hope that the default key contains a value of type "REG_SZ"

.... unluckily it could also be "REG_BINARY" or "REG_DWORD" or "REG_EXPAND_SZ" or "REG_MULTI_SZ" or "REG_QWORD"

and for any of this types, a specific reading method should be used..... better not risk reading wrong values using the blind brute force....

however, thanks for your proposed solution.

BrewManNH,

hmm, on that last one I get:

-1.#IND

Which is what you get when you divide zero by zero (e.g. 0 / 0), dividing a number that's not zero by zero you get 1.#INF (or -1.#INF if it's a negative number).

unluckily it could also be "REG_BINARY" or "REG_DWORD" or "REG_EXPAND_SZ" or

"REG_MULTI_SZ" or "REG_QWORD"...

99% of the time -- (Default), usually is REG_SZ.

Interesting ... didn't know that.

Chimp,

I kinda hijacked your thread - too much coffee. Sorry about that!

Good luck on your script.

ok... but the Murphy's law can always be around the corner...
