MText entity causes loop

[mblewis]

the following code is based on suggestion by R. Robert Bell
to get attribute tagstrings from BlockDef:

Public Sub Stdz_Malform_Tagnames2()
' BlockDefinition objects
' this Sub selects & modifies BlockDefinition objects, _
not BlockReference objects

On Error GoTo ERR_HAND
Dim oMyBlock As AcadBlock

Set oMyBlock = ThisDrawing.Blocks.Item(myTBlock)
Dim oEnt As AcadEntity

For Each oEnt In oMyBlock
If TypeOf oEnt Is AcadAttribute Then
oEnt.TagString = "MyNewTag"
End If ' AcadAttribute
Next oEnt
Exit Sub
ERR_HAND:
Resume
End Sub

PROBLEM: when oEnt is MText entity, endless loop results when "Next oEnt" is processed; execution causes error which triggers On Error which executes Resume which returns to "Next oEnt" which......
have set Watch on oEnt and when this trap occurs, oEnt Type=AcadEntity/lAcadMText in Watches box.

any suggestions for avoiding this debilitating loop?

Click on the word "Resume" in the code window and press the F1 key on your keyboard.

nice touch, fantum.

will add "Next" after Resume to break outta loop.

duh, why didn't i think of that? sometimes it takes others to correctly align the mirror for us to see the obvious.

What purpose do you have the error handler in there for anyway?

<hint> Look at your function description. Ask yourself "Is it doing too
much?" </hint>

back from vacating....
purpose for ErrorHandler?
during code trials, to catch any anomalies i didn't thinkof. usually eliminate after code proven.
in this specific case, it helped me to see endless loop caused by this Sub.
