VBscript not UAC and IE7 friendly

Hello Vista heads style_emoticons/ ,

I wanted to post here on vistax64 forums about my findings, related to

VB scripting, with Windows Vista in mind.

Firstly, I consider mysef a self-made power user of Windows products

mostly for multimedia tasks, so I am not sure my voice will be heard,

amongst IT experts and developers.

Also, I need to make something clear : There are still many websites

where one can download VB scripts and the likes. I don't mind that much

that the scripts were not tested with Windows Vista, but if you maintain

such web sites, please make a note stating that the methods of invoking

objects have considerably evolved.

Here is the test I conducted : I ran a simple VB script, with a

createobject internetexplorer.application instruction on a freshly

installed Vista machine. The script ran fine, until I disabled UAC.

Well, I didn't start this thread to fuel the debate whether UAC should

be turned off or not. Turning it on again didn't solve the problem.

I want to point out that Microsoft should warn people about severe

issues with code based on Visual Basic 6. I've read it was difficult for

them to publish Powershell, because of Vista security features. My guess

is that if the VB6 runtime was relying on ONE dll (like VB5 does), may

be things wouldn't be so bad.

Here is my point : If you are still an active script developer you

should turn to Powershell now, but also give a hand to people who have a

hard time running the scripts under Vista (the infamous cannot create

object error). The worst part of the story is that SOME VB scripts under

CERTAIN circumstances, on SOME machine may work fine, even on Vista PCs.

By the way, installing the Service Pack 1 improved things a bit, but not

by much.

For example, I had no problem with scripts made for Media Player. As I

said earlier, my abilities concerning editing scripts are rather

limited, I simply ran a few scripts and took notice of the bugs and

crashes. I have an Intel based computer, so this is not hardware

related.

These scripts had in common the use of createobject methods. I can

safely say that such methods interfere very badly with Vista security

features (Secure Desktop, UAC, virtualization of files & registry...).

At all cost, turn to Powershell if you want to use COM objects in

scripts. Windows Script Host was halted in the early stages of Vista

development.

Again, Powershell 2 is here for your scripting needs, I am not saying

it's perfect but it was made to provide automation features within a

production environment. Quite frankly, its debugging features are miles

away from those used internally, in the good old days of batch files.

Also, you certainly have noticed the job can be done using less

declarations and statements.

It would be a great relief if developers joined hands with IT Pros to

cool down things a bit. More and more people will turn to Vista SP1,

including some of those XP nostalgia driven we all know of. (you don't

want to wait for Vista 11, as it will probably be delayed too) We all

have an opportunity to deal with the issues brought by the extensive use

of deprecated code & components in the past...

I hope no one felt offended, and that I didn't sound too bold. Of

course, misconceptions always come in the way when you're trying to

convince specialists in their respective field. Note that if the scripts

I am talking about weren't useful at all, I wouldn't mind them to slowly

fade away.

As a power user, you should know that createobject internetexplorer.application

in a VB Script uses ActiveX
