Help using [FILE] object!

[HelliXSystems]

Hello,

I'm trying to detect some installed codecs with MF2, but first I need to check for some directories.

I'm using %PROGRAMFILES% and %PROGRAMFILES(X86)% in the [FILE] object but nothing happens. :S
How can I load the contents of this variables first or, how to use them properly in MF2? :confused:

Thanks a lot.

One way is to use the OS object (Dev only).

It can get the data with the Environment Variable expression:
for example [color:#000099]GetEnvVar$( "OS", "PROGRAMFILES")[/color] --> C:\Program Files


You can get various system paths with the YASO object you can download
on the right side under Quick File Links here in the Forum.
It's inside the Bonus Pack 1.

Oh. ok.. I'll try.

For now... How did you show a variable contents in screen with
some "dynamic" text or so?

I would like to put some pushbutton (or start frame event) to show in screen the actual path for program files, and if program files (x86) is present.


Thanks a lot.

There are some different objects to show text,
e.g. the String object:

Change alterable string > "path: " + GetEnvVar$( "OS", "PROGRAMFILES")

will result:

path: C:\Program Files

oh Thanks.
Sorry, and how I make that to work?

(I'm noob at MF2dev, I just switch from matchware mediator)

What exactly is your problem?

I always get syntax error.

Correctly. You have to create an OS object in the Frame Editor.

If you want to use the OS object inside a Behavior of an object you have to "connect" it by clicking the Import new objects icon in Behavior Event Editor beside the other objects icons. This Icon only appears if a non-connected object is available in the Frame Editor.
