Description

Hi,
     Iam using CUIT 'FindMatchingControls' on the WPF application topwindow and checking the 'Exists' property before performing action on the control to make sure that iam performing action on the correct instance of the control when there are more than one instance of application.

But FindMatchingControls returning empty list even one/more instances are present and then Exists property returning 'FALSE'.Exists property return false only after using FindMatchingControls API .

We are seeing this issue in VS2010 mainly and we checked in VS2012 also.Here is the MSDN Forum link (http://social.msdn.microsoft.com/Forums/en-US/vstest/thread/78603999-bae4-4d9a-ab16-f8dadb2d23cd)

Hi,

The workaround you suggested is not working as expected.It is giving the count including other technology main windows also.

Hi,

Sorry for the late reply.

In our test method we want to perform action on specific instance of the application if there are more than one running at that moment. To confirm that we get all instances ,compare the ProcessId ,and then perform action on the instance which we want to do


Thanks,
Nagasree.

Hi,
Please also let us know of your scenario here. Why is FindMatchingControls of a top level window important?

Hi,
Commenting out the recorded "HwndWrapper" class name for the WPF window works (Specifically this line of code: "this.SearchProperties.Add(new PropertyExpression(WpfWindow.PropertyNames.ClassName, "HwndWrapper", PropertyExpressionOperator.Contains));" ).

Before we go about fixing this may we know your scenario here?
