Error when escaping GetPoint

[NickBrege]

I am using the GetPoint function to prompt the user to select a point on screen.  However if the user changes their mind & presses escape, my code throws an exception.  I know I can use a Try/Catch to handle it, but I was wondering if there was a better way, as Try/Catch is not very elegant.  The pertinent code is below....

            Dim origin As Double() = CType(acadDoc.Utility.GetPoint(, "Select part origin: "), Double())
            xOrigin = origin(0)
            yOrigin = origin(1)

BTW ... I am using the COM/Interop API & VB.Net

Thanks...

Do you have to use the COM API for a particular reason? The following is a quick snippet for prompting the user for a point using the managed API. 

Dim aDoc As Document = Application.DocumentManager.MdiActiveDocument
Dim ed As Editor = aDoc.Editor
Dim opt As New PromptPointOptions(vbCrLf & "Select Part Origin: ")
Dim res As PromptPointResult = ed.GetPoint(opt)
If res.Status <> PromptStatus.OK Then Exit Sub
Dim selPoint As Point3d = res.Value

After selecting the point you can check the 'status' of the PromptPointResult.  If the status is okay you can then get the point using the result value.

Addition to what @hippe013 said:

It is what the COM API was designed: press ESC with AcadUtility.GetXxxxx() method raises exception. It is your responsibility to handle it. So, yes, you need to "Try...Catch..." it. If you are doing .NET API add-in, then there is no reason to use this COM API method at all.
