Error Messages when debugging

[Ukemi72]

Hello,

when i'm debugging a new code the are sometimes error-messages like "eInvalidInput". And so are there more of these messages.
Is there a list / explanation of waht these messages mean and where to look where the mistake is in the code?

Greeting,

I am unsure of a single (presumably up-to-date) list of all possible Exceptions; it's more likely that you use Object Browser to diagnose the calling Methods used in your project, and use either try + catch [+ finally] block with an appropriate user notification, or simply logic in your code.

Since you haven't posted any code, one cannot know for sure, but the Exception you listed suggests that you called a Method with an invalid parameter. More information is needed.

Those types of messages are ObjectARX constants. The .Net api just provides wrappers for many arx methods. For any particular method, see ObjectArx.chm in the sdk. Most likely, you supplied the wrong type to an argument, like BlackBox mentioned. For example, the method called for you to pass it an ObjectID, and you supplied it as a System.String.

Hi susan.lee
Welcome on board
One possible and easy way is to use boolean variable
for final information at the end of program, you may want to
use instead other variables say one for particular action
within your program, but then you have to display al of then
in the screen or in the command line
(I'm personally still avoid to use MsgBox)
Give this a try:

       <CommandMethod("tex")> _
        Public Shared Sub TestForExceptionMessages()
            'create variable to inform user about exception
            Dim what As Boolean = True
            ' create variable for informative string
            Dim result As String = String.Empty
            Dim doc As Document = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument
            Dim db As Database = doc.Database
            Dim ed As Editor = doc.Editor

            Dim peo As New PromptEntityOptions(vbLf & "Please, select a line: ")
            peo.SetRejectMessage(vbLf & "Not a line...")
            peo.AllowNone = False
            peo.AddAllowedClass(GetType(Line), True)
            Dim per As PromptEntityResult = ed.GetEntity(peo)

            If per.Status <> PromptStatus.OK Then
                Return
            End If

            Dim ppo As New PromptPointOptions(vbLf & "Please, specify a point: ")
            ppo.AllowNone = True
            Dim tm As Autodesk.AutoCAD.ApplicationServices.TransactionManager = doc.TransactionManager
            'to force draw entity on screen
            tm.EnableGraphicsFlush(True)
            Using tr As Transaction = tm.StartTransaction()
                'cast selected objec as line
                Dim ln As Line = DirectCast(tr.GetObject(per.ObjectId, OpenMode.ForRead), Line)
                Dim btr As BlockTableRecord = DirectCast(tr.GetObject(db.CurrentSpaceId, OpenMode.ForWrite), BlockTableRecord)
                'create variable to count picked points
                Dim pcount As Integer = 0
                Dim id As ObjectId = ObjectId.Null
                Try
                    While True
                        Dim ppr As PromptPointResult = ed.GetPoint(ppo)
                        If ppr.Status <> PromptStatus.OK Then
                            ed.WriteMessage(vbLf & "Inerrupted by user.")
                            Exit While
                        ElseIf ppr.Status = PromptStatus.OK Then
                            'count picked points
                            pcount += 1
                        End If

                        ppo.Message = vbLf & "Specify next point: "

                        Dim pt As Point3d = ppr.Value

                        Dim nl As New Line(pt, ln.EndPoint)
                        id = btr.AppendEntity(nl)
                        tm.AddNewlyCreatedDBObject(nl, True)
                        ' force to draw entity
                        tm.QueueForGraphicsFlush()
                        ' confirm force
                        tm.FlushGraphics()
                        ed.UpdateScreen()
                       
                    End While
                    ed.WriteMessage(vbLf & "Number of oints: {0}: " & vbLf, pcount)
                    ' gather all possible exceptions
                    If pcount < 1 Then what = False
                    ' build informative string, e.g.:
                    result = IIf(what = True, "Success", "Fail")
                    'catch autocad based exception
                Catch ex As Autodesk.AutoCAD.Runtime.Exception
                    what = False
                    ed.WriteMessage(vbLf & ex.Message & vbLf & ex.StackTrace & vbLf)
                    'catch high level exception
                Catch exsys As System.Exception
                    what = False
                    ed.WriteMessage(vbLf & exsys.Message & vbLf & exsys.StackTrace & vbLf)
                Finally
                    ' commit transaction
                    tr.Commit()
                    ' inform user about how to program ended up with
                    ed.WriteMessage(vbLf & "Program ended up with result of ""{0}""" & vbLf, result)
                End Try
            End Using
        End Sub

So my recommendation is necessary to check each user input and each execution of individual commands
in your program and report these results to the command line, then after a thorough check of this program
you have remove some of them
