MSH Object Viewer

Fuction to see/Change members of Objects in a Gui.
(a bit as get-member does on the Commandline)

it is a great help exploring MSH for me

some examples of usage :

ov (gi test.txt) -> file properties

ov(new-object system.management.managementclass)<- you can change class from GUI so this is giving you a WMI browser. Look at the difference between the following commands !: (in the latter you don't see the methods, and MSH is taking the instance already) ov(new-object system.management.managementclass("win32_operatingsystem")) ov (get-wmiObject win32_operatingSystem) ov(gps[0]) -> info of first process
ov ($var) -> Info on variable.
ov(dir) -> dir in GUI

# will show an Object in a PropertyGrid (propertywindow in Visual Studio)
# this is an easy way to look at MSH objects.
# you can read / write the object properties.
# and it has some nice editors for some properties
# eg. ov (gi test.txt)will let you change the date by a calendarview

$form.text = "$args"

Nice script. Just one question: shouldn't you set the scope of the function to global? And i think that you also need to set the scope for the set-alias cmdlet. am i wrong here? thanks.

you can also start the script dotsourced, like this :

. .\Objectviewer.msh

I did think I mentioned somewhere but not in this post.

this loads the whole script in the Global scope,thats the way I have it in my profile.

but you can also set the scope of the function to global as you mentioned.

the way I use often also, is just pasting the code in the MSH Console, this will get the function in the global scope also.

I mostly leave it to the user, but in this case only declaring a function in a subscope makes not much sense indeed, but if you use it as a subfunction in a script, loading global would not be wanted.

I think it's better to fail and than think, oops I have to dot-source this, as messing up your global scope without realising.

for more info try searching my blog for "tuning profile"

thanks for the Comment
