Selection Set Filter with more than two object filters

jdaltonAWVZ3 — Mon, 28 Jul 2025 11:21:12 GMT

I am writing a program that allows the user to select the following objects: MTEXT, TEXT, and MLEADER, and iteratively go through them and edit the text. The problem arises when I try to put all three object types in the selection filter. Below is what I have currently:

Dim peo As New PromptSelectionOptions With { .MessageForAdding = vbLf & "Select Text, Mtext, or MLeader to adjust text: ", .MessageForRemoval = vbLf & "Select to Remove: " } Dim filterList As New List(Of TypedValue) filterList.Add(New TypedValue(DxfCode.Operator, "<OR")) filterList.Add(New TypedValue(DxfCode.Start, "MTEXT")) filterList.Add(New TypedValue(DxfCode.Operator, "<OR")) filterList.Add(New TypedValue(DxfCode.Start, "TEXT")) filterList.Add(New TypedValue(DxfCode.Start, "MLEADER")) Dim acSelFtr As SelectionFilter = New SelectionFilter(filterList.ToArray()) Dim selectedResult As PromptSelectionResult = acEd.GetSelection(peo, acSelFtr) If selectedResult.Status <> PromptStatus.OK Then Exit Sub

When I run it in the current configuration is the program stops before it actually gets the selection, making me think that my filter is set up incorrectly. I could not find any examples online of a filter containing three objects or more.

Much help would be appreciated! Thanks!

Hi,

Try like this:

Dim filterList As New List(Of TypedValue) filterList.Add(New TypedValue(DxfCode.Operator, "<OR")) filterList.Add(New TypedValue(DxfCode.Start, "MTEXT")) filterList.Add(New TypedValue(DxfCode.Start, "TEXT")) filterList.Add(New TypedValue(DxfCode.Start, "MLEADER")) filterList.Add(New TypedValue(DxfCode.Operator, "OR>"))

Or simply:

filterList.Add(New TypedValue(DxfCode.Start, "TEXT,MTEXT,MLEADER"))

use a comma, and wildcards

(Db.DxfCode.kDxfStart, "*TEXT,*LEADER")
