    MadGrb Since none of the suggested solutions worked, this issue definitely requires deeper investigation. Please contact our Support Team and describe it as minutely as possible.

     

    Our Support Team and Dev Team would need to reproduce it in their lab, so please send them a sample app and a sample TC project for this. 

     

    Please post the solution you get from them here, thank you🙂

Hi,

 

OnUnexpectedWindow event is triggered in TestComplete when some modal window (application or system) prevents your test code to interact with UI elements out of this modal window. Examples of such interactions are clicks, setting focus and sending keys sequences. Exactly like it looks like for the human user.

Note, that if your test code does not interact with UI but operates on tested application's methods/properties, then modal window will not block such interactions and thus the OnUnexpectedWindow event will not be triggered.

For example, <inputField>.SetText('blah') will always succeed as it uses direct property assignment and does not interact with the <inputField> element via GUI. On the contrary, <inputField>.Keys('blah') will trigger the OnUnexpectedWindow event if the form with the field is blocked by some other modal message window.

The good approach to get a reliable test code in the cases like this is to use .Activate for forms/windows and .Focus methods for controls before interaction with them to ensure that forms/controls are not blocked.

E.g.:

<form>.Activate;

<form>.<inputField>.Keys('blah');

<form>.<inputField2>.Keys('blah')
