Adding a new Column from Shell Properties

Directory Opus has script support for Windows shell properties, making it easy for a script to enumerate properties in the system and retrieve the properties for a file.

• Use FSUtil.GetShellPropertyList to retrieve a list of properties (optionally matching a wildcard pattern).
• Use FSUtil.GetShellProperty to get the value of one or more properties for a file.
• Use Item.ShellProp to get the value of a single property for the item.

Below is an example script add-in that adds columns to Opus that show the value of shell properties for DWG (AutoCAD) files added by a third party tool.

Function OnInit(initData)
    initData.name = "DWG Columns"
    initData.desc = "Adds DWG Columns from the JTB World extension"
    initData.copyright = "(c) 2016 jpotter"
    initData.version = "1.0"
    initData.default_enable = true
    initData.min_version = "12.0.8"

    Dim props, prop, col
    Set props = DOpus.FSUtil.GetShellPropertyList("dwg.*", "r")

    for each prop in props

        Set col = initData.AddColumn
        col.name = prop.raw_name
        col.method = "OnDWGColumn"
        col.label = prop.display_name
        col.justify = "left"
        col.autogroup = true
        col.userdata = prop.pkey

    next

End Function

Function OnDWGColumn(scriptColData)

    scriptColData.value = scriptColData.item.shellprop(scriptColData.userdata)

End Function
