Enables you to add new methods to test object classes or change the behavior of an existing test object method during a run session.

Sub Copy (edit)
    Edit.Click 3, 3
    Edit.SetSelection 0, Len(Edit.GetROProperty("text"))
    Edit.Type micCtrlDwn + "c" + micCtrlUp
End Sub

One way to call the code above:

Call Copy(Dialog("Login").WinEdit("Agent Name:"))

Using RegisterUserFunc:

RegisterUserFunc "WinEdit", "Copy", "Copy" 

Dialog("Login").WinEdit("Agent Name:").Copy

You’re simply adding a new static method to the test object class.

i have one basic question. Why do we register? What is the need for registerin? When should we register?

Thx,

Your observation is correct. But, it is to be noted that RegisterUserFunc only works for test object classes. Once you add .Object to any test object class, the class is no longer recognized as a QTP test object class. This can be tested by added “.Object” to any test object and trying to retrieve its original test class – won’t work.

Yes Anshoo, DOM object/methods could be used inside overriden function body. However DOM object itself can not call overridden function defined for that test object. Have you came across such scenario and found it working. If not,is there any workaround for such limitation?

Here is the example code where DOM object can not call overridden function:-

‘Needs OR for Google page
Function MySet (obj, sVal)

Dim sPrev

sPrev = obj.GetROProperty(“value”)

Reporter.ReportEvent micDone, “Previous Value was ” & sPrev, sPrev

MySet=obj.Set(sVal)

Reporter.ReportEvent micDone, “Set Value is ” & sVal, sVal

End Function

‘Without using overriden function – Calling default SET
Browser(“Google”).Page(“Google”).WebEdit(“q”).Set “QTP”

set pgObj = Browser(“Google”).Page(“Google”)
set txtObj = pgObj.Object.all.namedItem(“q”)

‘Defined overridden function
RegisterUserFunc “WebEdit”, “Set”, “MySet”

‘With using overridden function – Calling MySet – This will not work with DOM object – Error
txtObj.Set “Inception – Dreaming now…”

‘With using overridden function – Calling MySet – This will work with test object
Browser(“Google”).Page(“Google”).WebEdit(“q”).Set “Inception – In Real World…”

‘Undefined overridden function
UnRegisterUserFunc “WebEdit”, “Set”

Browser(“Google”).CloseAllTabs

For example a link object is formed by DOM and click method executed. It would not call overriden function. The reason thought by him seems appropriate – As we use micclass in registeruserfunc and micclass is not used in DOM, it will not work.

Do you know such limitations of registeruserfunc and is there any workaround?

Thank you very much for your kindness.
