Display a Message Box after running nodes

Hi all,

I’m trying to display a message box after running a set of nodes. However, Dyanmo seems to ignore any nodes before the message box script and displays the message box first and then run the nods. I tried it with Data-shapes and couple of custom python scripts and they all did the same thing. I even tried to force the message box script to wait for the other nodes with the “passing through” node, but still no luck so far!

Am I doing something wrong or this is how Dynamo deals with any UI nodes (Displays all windows first and then run the nodes)?


The python script for the message box:

import clr
from Autodesk.Revit.UI import TaskDialog
msg = IN[0]
msgBox = TaskDialog
OUT = msgBox.Show(“Done!”,msg)

Place a Transaction.End node before your Python Script node. That way the changes to th emodel get committed before the message box is displayed.

You can use Passthrough node from Clockwork package as well :slight_smile:

Thanks a lot. Working perfectly now!

Thanks HozzZam. Without the Transaction.End node, passthrough didn’t do it for me. However, combining these two nodes together allowed me to pop-up multiple windows, which is ultimately what i was looking for!

You can try it.

I wanted to display an instructional message box in some of my Dynamo Player scripts only if needed parameters were missing.

So I started with the python script I found in the above posts (Thanks) and added to it - see: Message Box instruction if parameter missing
