Functions providing process-information

[dabus]

Ok, since someone told me he used pv.exe for getting more informations about a process, I made a simple udf to get things done for me.

You need this little one to work: http://www.teamcti.com/pview/pv_5_2_2.zip

I works as expected on a WinXP pro SP1.

Since I think it's quite usefull, I post it here.

I hope you find it usefull too.

    Script function: Functions that provide process-information
    
    Changes:
    0.0.1   - a simple bunch of stdout-functions, but it works
    0.0.2   - added some calltips
    0.0.5   - added documentation
    0.0.6   - added @error-feedback
    0.0.7   - _ProcessGetTime returns an array now (closer to standards)
    0.0.8   - Use a Generic template 

    Note: Replace this sting >>E:\Programme\Smallstuff\ProcessViewer\pv.exe<< with the correct location!!!

    Please paste this into your calltips.api:
