Snoop snoops on itself rather than expected app

Sep 14, 2011 at 3:35 PM


I have a .NET 4.0 WPF application that I am trying to snoop upon, however when I select it from the drop-down list or use the crosshair selection the resulting magnifier/snoop dialogue seems to show the SnoopUI rather than my application; i.e. snoop is snooping on itself! Has anyone else encountered this? I've had a quick search through the discussions but couldn't find any similar issue, I've tried running as administrator, etc, same result.

Using v2.7.0

Hi Alex,

Have you tried to press CTRL + Shift over the window you want to snoop? I got this once before, but I was able to snoop the correct window by simply pressing CTRL + Shift over the window I want to Snoop. If you get a chance to try, let me know what happens.

I see the same behavior. It doesn't matter whether I select my app in the drop down menu or I use the crosshair. Snoop keeps hooking itself...

Hitting Ctrl+Shift has no effect.

Is it possible to send a sample application which illustrates the issue?

You could create an issue in the Issue Tracker and from there attach the sample project.

I'm on my way to China, but I'll try take a look at making a repro of this when I get back. I've noticed that if I use the crosshair to select my app, I can at least get the control events to print in Snoop, and from there I can drill into the actual control hierarchy.

Got the same and using CTRL + Shift solve it.
