Back to Methods Reference

Gets a real (double) value from the user.

Signature

VBA : RetVal = object.GetReal([Prompt])

VL : RetVal = (vla-GetReal object Prompt)

(vla-GetReal util "\nEnter Real Number : ")

• Object : Utility
  The object or objects this method applies to.

• Prompt : Variant (string); input-only; optional
  The text used to prompt the user for input.

• RetVal : Double
  The value returned from the user.

Remarks

AutoCAD pauses for user input of a real value, and sets the return value to the value that the user enters. The Prompt parameter specifies a string that AutoCAD displays before it pauses. The prompt is optional.

If a keyword is returned instead of a double, AutoCAD will generate the error message "User input keyword." Use the GetInput method to obtain the keyword from the return value.

Example :

(defun c:al-getreal ()

(vl-load-com)

(setq util (vla-get-utility 
                   (vla-get-activedocument 
                        (vlax-get-acad-object))))
                        
(setq thereal (vla-GetReal util "\nEnter Real Number : "))

(princ thereal)
