AutoCAD VBA rubber banding

AutoCAD VBA rubber banding

AutoCAD VBA rubber banding

In a VBA program when I have the user select an area on the screen, I call the GetUserPoint twice (to get both points) and then call the SelectByPoints sub. Doing this, the user does not have rubber banding as they move the mouse from their first selection point to the second. It seems as if it's not working for the user if they don't see the familar rubber banding. How do I get the rubber banding outline to show up? My code is shown below.

Public Sub GetUserPoint()
PointPicked = True
With ThisDrawing.Utility
    On Error GoTo NoInput
    varPick = .GetPoint(, vbCr & "Pick a point: ")
    .Prompt vbCr & varPick(0) & "," & varPick(1)
    On Error GoTo NoInput
End With
Exit Sub
PointPicked = False
End Sub


Public Sub SelectByPoints()
On Error Resume Next
Set objSS = ThisDrawing.SelectionSets.Add("TEMP")
''''objSS.Select 1, Pt1, Pt2, intCodes, varCodeValues '   5 = all, 1 = use Pt1 and Pt2
objSS.Select 1, Pt1, Pt2
End Sub

You've already got the code 95% written.. :)

All you have to do is use Pt1 in a second .getpoint statement, you've been passing the option by..

Pt2 = .GetPoint(Pt1, vbCr & "Pick second point: ")

That's better, but I'm getting a line from the first picked point to the cursor. What I was hoping for is a rectangle like what you get if you invoke the ERASE command.

Ahh... I see what you're trying to do now.

What might be handy for you is to let the user select however they like. That method is simply (.selectonscreen) you user will then be able to select individual entities, or window, or window polygon, etc. You can even apply filters if you like. It looks something like this:

'Return a selectionset of Sprinklers
Public Function GetSprinklers() As AcadSelectionSet
    Dim objSetSprinklers As AcadSelectionSet
    Dim GroupCode(0 To 1) As Integer
    Dim DataValue(0 To 1) As Variant
    Dim FilterType As Variant
    Dim FilterData As Variant

    Set objSetSprinklers = MakeSelectionSet("02810sprinklerss")
    GroupCode(0) = 0:    DataValue(0) = "Insert"
    GroupCode(1) = 8:    DataValue(1) = "02810-sprinkler"
    FilterType = GroupCode: FilterData = DataValue
    ThisDrawing.Utility.Prompt "Select Sprinklers:"
    objSetSprinklers.SelectOnScreen FilterType, FilterData
    Set GetSprinklers = objSetSprinklers
End Function
