Test Complete unable to perform Click TAB Operations on an application developed using .Net & VC++

We are Automating an application developed in .Net, VC++ & below is the issue



Please find the sample set of scripts from Test Complete & QTP:

Test Complete is very slow (takes 5 mins) to perform one Click Tab action, whereas QTP is doing the same in seconds. 



Recording/Spying is done fast, but the issue occurs only during run time



I  need a solution in Test Complete to quickly click & perform the actions..



Test Complete Script: Very Slow(15 mins to execute)

 

Sub Test1

  Dim sysTabControl32

  Set sysTabControl32 = Aliases.tc_client.wndAfx.pageClientPane.page32770.pageSplitterPane1.pagePDVView.SysTabControl32

  Call sysTabControl32.ClickTab("Main      ")

  Call sysTabControl32.ClickTab("Futures Cross      ")

  Call sysTabControl32.ClickTab("Index/Bonds      ")

  Call sysTabControl32.ClickTab("Roll Dates      ")

  Call sysTabControl32.ClickTab("Break      ")

End Sub

 

 

QTP : Just takes 10 seconds
