AutoLISP Syntax

The recommended convention is passing the control identifier directly:

Copy Code
(Odcl_Grid_ShowComboBox MyControlReference [as Reference] nRowIndex [as Integer] nColIndex [as Integer] nStyle [as Integer] (list sChoiceValue1 [as String] sChoiceValue2 [as String] ... sChoiceValueN [as String] ) )

Copy Code

(Odcl_Grid_ShowComboBox 
		MyControlReference [as Reference]

		nStyle [as Integer]
		(list
			sChoiceValue1 [as String]
			sChoiceValue2 [as String]
			...
			sChoiceValueN [as String]
		)
	)

An alternative convention is to identify the control by providing the project file, the dialog name and the control name:

Copy Code
(Odcl_Grid_ShowComboBox ProjectFile [as String] DialogName [as String] ControlName [as String] nRowIndex [as Integer] nColIndex [as Integer] nStyle [as Integer] (list sChoiceValue1 [as String] sChoiceValue2 [as String] ... sChoiceValueN [as String] ) )

		nRowIndex [as Integer]
		nColIndex [as Integer]
		nStyle [as Integer]
