Child Objects in QTP scripts with examples

Many at times in Scripting we come across scenarios where we need to count the objects in the application or even highlight a child object like highlighting a text box or check and uncheck check boxes using scripting in QTP.

Below are some of the examples where in you can do different actions. For our example we are using Flight Reservation application as reference.

'Script to count the number of child objects of flight reservation application
Set chd_obj = Dialog("text:=Login").ChildObjects
msgbox chd_obj.count

'Script to highlight all the child objects in Login dialog of flight reservation application
Set chd_obj = Dialog("text:=Login").ChildObjects
For i = 0 to chd_obj.count - 1
chd_obj(i).Highlight
Next

'Script to highlight all the child objects(buttons) in Login dialog of flight reservation application
Set button_obj = Description.Create
button_obj("nativeclass").Value = "Button"

Set chd_obj = Dialog("text:=Login").ChildObjects(button_obj)
For i = 0 to chd_obj.count - 1
chd_obj(i).Highlight
Next

'Script to check and uncheck all the check boxes in open order dialog box of flight reservation application
Set checkbox_obj = Description.Create
checkbox_obj("Class Name").value = "WinCheckBox"

Set chd_obj = Window("text:=Flight Reservation").Dialog("text:=Open Order").ChildObjects(checkbox_obj)
For i = 0 to chd_obj.Count - 1
chd_obj(i).Set "ON"
chd_obj(i).Set "OFF"
Next
