    OK, I'm not sure I'd do that code...  

     

    So... why use "WaitChild" over "FindChild"?  Wait allows you to customize the wait time for TestComplete to wait for the object to be present.  Now, just came to memory, you CAN use FindChildEx.  This combines the search functionality of FindChild with the Wait feature of WaitChild.  

     

    If you use FindChildEx, make sure that you set the "refresh" property to "true".  That might help with the problem that you're originally reporting.  Basically, what's happening is that you're finding the object but after the object is found, it's destroyed and recreated... changing the in-memory handle of the object hence why it says it is destroyed before you are able to act on it.

     

    So... there is something that's happening between when you run your application and when you try to find that child object that is causing that object to be destroyed and recreated.  If I was in your shoes, what I'd do is start doing some investigation around that startup process of your application to see if there is some other property or process or something that will give you an indication that the application is ready for interaction before you go searching for the child object.

It's not that you're waiting for the property of the child... you're waiting for the child itself with those "wait" methods.

 

Looking at your code:

 

So, you're using FindChild to find a process....  I wouldn't do it that way....  I'd use "Sys.WaitProcess" instead...  Then I'd do a WaitChild to wait for the child object of your process to be present...  

 

As for the "Activate"... not sure you need that... what are you hoping to do with "Activate"?

  • Good explanation of the "wait" methods! I would still like to be able to wait for some "CanCallActivate" property on the child object though.
  • Thank you for the suggestion of changing FindChild to WaitProcess / WaitChild! I will try that.
  • Activate is used to ensure that the window is on top.

 

Kind Regards
