#Log Error Dialogs#

*My application can potentially display a dialog containing an error message during test execution. The dialog can appear multiple times and will not always appear at the same point in the test, therefore I cannot use a standard Dialog Handler step.
 
I want to capture these error messages and automatically handle these dialogs if they appear.*

##Solution##

This is possible with a coded solution. The stipulation is that the dialog is displayed the same way and has the same title in each browser:

![Dialog][1]

1.Add an Assembly Reference to *System.Windows.Forms*.
2.Add a <a href="/https/raw.githubusercontent.com/code-in-test/features-in-code#Coded-Step" target="_blank">coded step</a> to the beginning of the test that creates a dialog monitor.
3.Define a custom dialog handler that is referenced in the coded step.
4.Override the *OnAfterTestCompleted* method to log whatever text the dialog handler captured.
5.Auto reset the dialog handler in case of multiple dialogs.

Here is the full code-behind file, excluding the standard *using/Imports* statements and the Dynamic Pages Reference region:
