About Requesting a Keyword (VBA/ActiveX)

The GetKeyword method prompts the user for input of a keyword at the AutoCAD Command prompt.

This method accepts only one parameter, which is the prompt string. The keywords and input parameters are defined with a call to the InitializeUserInput method.

Get a keyword from the user at the AutoCAD Command prompt

The following example forces the user to enter a keyword by setting the first parameter of InitializeUserInput to 1, which disallows NULL input (pressing Enter). The second parameter establishes the list of valid keywords.

Sub Ch3_KeyWord()
  Dim keyWord As String
  ThisDrawing.Utility.InitializeUserInput 1, "Line Circle Arc"
  keyWord = ThisDrawing.Utility.GetKeyword(vbCrLf & "Enter an option (Line/Circle/Arc): ")
  MsgBox keyWord, , "GetKeyword Example"
End Sub

A more user-friendly keyword prompt is one that provides a default value if the user presses Enter (NULL input). Notice the minor modifications to the following example:

Sub Ch3_KeyWord2()
  Dim keyWord As String
  ThisDrawing.Utility.InitializeUserInput 0, "Line Circle Arc"
  keyWord = ThisDrawing.Utility.GetKeyword(vbCrLf & "Enter an option (Line/Circle/<Arc>): ")
  If keyWord = "" Then keyWord = "Arc"
  MsgBox keyWord, , "GetKeyword Example"
End Sub
