winclass
Parameter winclass (String) may be used, along with winstyle and winstylex, as an alternate way of specifying a control type. Note that this technique is only practical for controls that do not require special processing by A-Shell. (For example, it can be used safely to create a new style of button or static text control, since these do not require any special handling other than to process their click command. But it cannot be used to create a complex control like a spreadsheet, up-down, or property sheet, since in order to be used effectively, these would require integration with other A-Shell operations.)
