[GIS] Updating ArcMap Statusbar from AddIn

add-inarcgis-10.0arcobjects

I'm using this statement in an add in to update the first pane of the ArcMap 10 statusbar:

ArcMap.Application.StatusBar.set_Message(0, message);

When the method is called, no exceptions are raised. In my OnClick method, I display a message box and when that occurs, I do see the text of the last message. It seems like the pane needs to be refreshed, but I don't see a method that does that.

I tried:

 ArcMap.Application.RefreshWindow();

but that doesn't help.

Try adding a Application.DoEvents, the STA thread probably don't have time to consume events. An other way would be to create a background worker thread that does your work, that would free the STA thread to process the event loop.

In your code that you gave as an example. In my testing this worked for me.

new Thread(() =>
{
   MessageBox.Show(String.Format("The value '{0}' is not an integer!", currentValue));
}).Start();

Edit To incorporate the great comments, and as Petr pointed out that this way may be dangerous here is the other way of doing this as well:

SynchronizationContext.Current.Post(_ => MessageBox.Show("Message"), null);

Thanks to Kirk and Petr for this!

[GIS] Automatically display related records for selected feature in tablewindow with ArcObjects

Is there a way through ArcObjects to automatically display the related table(s) for the selected feature in ArcMap in the attribute window (tablewindow) without the user having to click on it and select the related table

This is definitely possible - I remember writing a script to do it years ago. In my case I generated a new standalone window and summarised the feature's info along with the related features' info.

Unfortunately I no longer have the code handy, but searching on ArcScripts shows another related script which might give some clues for how to traverse a relationship class programatically.

Hopefully this will give you some clues - sorry I can't be more directly helpful.
