Inventor commandmanager.Pick method problem

[Anonymous]

I have some problem using the inventor commandmanager.pick method. Below is the code. (Attached my VBA userform). When the userform run, I will pick the QTY from the userform, then I have used pick method to pick the dimension). the 'Pick" method does not work well. Sometimes I could able to pick the dimension, but many times no. Also attached the class function also, if anything wrong in below code, please advice.

Option Explicit
Public txtQTY As String
Public Sub Add_PrefixQTY_To_Dim()
Dim oSelect As New clsSelect
On Error GoTo finish:
' Declare a variable and create a new instance of the select class.

frmAddPrefix.Show
txtQTY = frmAddPrefix.txtQTY

Do
Dim oDrawDoc As DrawingDocument
Dim oRefDoc As Document
Set oDrawDoc = thisapplication.ActiveDocument
' Call the Pick method of the clsSelect object and set the filter to pick any dimension.
Dim oDrawDim As DrawingDimension
'Filter out anything that is not a dimension
Set oDrawDim = oSelect.PickDim(kDrawingDimensionFilter)
Dim oStr As String
'Check to see if the text is already there
If InStr(oDrawDim.Text.FormattedText, "X") = 0 Then
' If "TYP" has not been added already, add it
oStr = txtQTY + " " + oDrawDim.Text.FormattedText
oDrawDim.Text.FormattedText = oStr
' If "TYP" has been added already, skip this dimension and continue selecting
ElseIf InStr(oDrawDim.Text.FormattedText, "X") <> 0 Then
Dim i As Integer
Dim Pos As Integer
Dim FindChar As String
Dim SearchString As String
SearchString = oDrawDim.Text.FormattedText
FindChar = "X"

For i = 1 To Len(SearchString)
If Mid(SearchString, i, 1) = FindChar Then
Pos = i
End If
Next i

Dim FindXPos As String
FindXPos = Replace(oDrawDim.Text.FormattedText, Mid(oDrawDim.Text.FormattedText, 1, Pos), txtQTY)
oStr = FindXPos
oDrawDim.Text.FormattedText = oStr
End If
Loop
finish:
Unload frmAddPrefix

End Sub

You mention the CommandManager.Pick, but this is not used on the sample code you provided on the post....can you clarify?

I could not find any previous report on this. There are some samples at our help file, such as

>>>>>>>>>>

Public Sub GetSingleSelection()

    ' Get a feature selection from the user
    Dim oObject As Object
    Set oObject = ThisApplication.CommandManager.Pick(kPartFeatureFilter, "Pick a feature")

    MsgBox "Picked: " & oObject.Name

End Sub

Sorry. it was not commandmanager issue, it is thisapplication.userinterfacemanager.doevents issue.
