Front end chooser ? anyone ?

SAScooby · 10-10-2005, 12:54 PM

Hi

I am not sure if this has been an idea before

but what about a front end chooser ?
an exe that replaces explorer.exe as the shell
this app then has a few customisable buttons on it

frodo nmc
rr phonecontrol
winamp explorer.exe
centrafuse car amp
media engine obd

so that you can then choose the front end you want, of course if there is no selection, then perhaps a default is done automatically, there may be some times you want to use the pc but not through the front end, and to wiat for the front end to open up and then close
what about it ?

I would use that if someone made it...

I wrote an app that does something similiar to this. Basically because I/we all enable our front ends as the shell sometimes this can limit our abilities to access certian features of our PC's. In my hardware design my front end is stored on an external 2.5" drive. Forseeing myself forgetting to put in the 2.5" drive ocasionally, causing the system to boot with no front end, I devised a plan.

My plan was to have a CF card (in the MII's CF slot) with my frontend on it. The OS on a CF card connected to IDE and a 2.5" External drive capable of mass storage, with my front end on it.

The shell I designed is actually the new windows shell. When loaded it figures out if the primary front end is available (on the 2.5" drive) If its not then looks for the secondary front end (located on the CF card) If thats not available, then is loads explorer.exe... If thats not available it will try to load a "launch file window" (for diagnostics)

The app has an editable XML file where you can chose (Primary,Secondary,Emergency) applications. Also one addition, is that it watches the primary and secondary applications for termination (a crash) if the app crashed, it relaunches it within 5 seconds. Like windows will do to its shell.

I can post some base code OR possibly re-design the app to how you guys want it... Of course I'll do this only if there's enough interest. But when I get home I will at least post the basecode.

Yip, this is getting on to the right track

IntellaWorks · 10-10-2005, 01:23 PM

Someone could easily edit the code to do what you guys wanted. Its all based of XML for one thing so that would really make it easier.

Below is the XML file. In directory tag you put the applications shell path
The priority is self explanitory.
The name tag is for the process name, so launch your app press ctrl + alt + delete and look for the exe of your front end and put that here.

Oh and don't try Explorer.exe if its already as your windows shell, it freaks the machine out... not sure why...

Code:


<settings>

	<application>
		<directory>C:\carinterface.exe</directory>
		<priority>1</priority>
		<name>CarInterface</name>
	</application>

	<application>
		<directory>E:\</directory>
		<priority>2</priority>
		<name>CarInterface</name>
	</application>
	
	<application>
		<directory>C:\</directory>
		<priority>3</priority>
		<name>Emercency</name>
	</application>
	

	

</settings>
