Ruby latest stable (v2_5_5) - 0 notes - Class: WIN32OLE_VARIANT

new(*args) public

Returns Ruby object wrapping OLE variant. The first argument specifies Ruby object to convert OLE variant variable. The second argument specifies VARIANT type. In some situation, you need the WIN32OLE_VARIANT object to pass OLE method

shell = WIN32OLE.new("Shell.Application")
folder = shell.NameSpace("C:\\Windows")
item = folder.ParseName("tmp.txt")
# You can't use Ruby String object to call FolderItem.InvokeVerb.
# Instead, you have to use WIN32OLE_VARIANT object to call the method.
shortcut = WIN32OLE_VARIANT.new("Create Shortcut(\&S)")
item.invokeVerb(shortcut)
