Hi

 

I am trying to get my code to work more like some of the built in autocad commands below is the code I have come up with. However if the string returned is not a Keyword or a string that can be converted to a double it is then not acceptable input. How do I jump back to re ask for the input. I could use goto I guess but thats not good practice is there a better way?

 

           

           

'ask the user if they want to accept the sureface level at the lid level or enter a new one

           

Dim acDoc AsDocument = Application.DocumentManager.MdiActiveDocument

           

Dim pKeyOpts AsPromptKeywordOptions = NewPromptKeywordOptions("")

           

Dim CurrentLidLevel AsDouble = oStructure.RimElevation

            pKeyOpts.Message = vbLf &

"Structure Lid Level:" & CurrentLidLevel

            pKeyOpts.Keywords.Add(

"Surface")

            pKeyOpts.Keywords.Add(

"New")

           

'pKeyOpts.Keywords.Default = "New"

            pKeyOpts.AllowNone =

True

           

Dim pKeyRes AsPromptResult = acDoc.Editor.GetKeywords(pKeyOpts)

           

SelectCase pKeyRes.StringResult

               

Case"Surface"

                   

'Do nothing

                    Lidlevel = CurrentLidLevel

               

Case"New"

                   

'ask user for grade to use

                    Lidlevel = acDoc.Editor.GetDouble(vbCrLf &

"Enter New lid level of Structure").Value

               

Case""

                   

'Enter key hit

                    MsgBox(

"using surface level for lid level")

               

Case Else

                   

'Check if input was a number that we can work with

                   

Try

                       

Double.TryParse(pKeyRes.StringResult, Lidlevel)

                   

Catch ex AsException

                   

EndTry

 

 

                   

'enter pressed do nothing

           

EndSelect

Use GetDouble with PromptDoubleOptions and AutoCAD will automatically reprompt if the user enters anything that is not a double or a keyword.  Setting AllowNone = true allows the Enter Key.
