How to handle Run-time errors?

On Error Resume Next : causes execution to continue with the statement immediately following the statement that caused the run-time error, or with the statement immediately following the most recent call out of the procedure containing the On Error Resume Next statement. This allows execution to continue despite a run-time error. You can then build the error-handling routine inline within the procedure.
Using "Err" object msgbox "Error no: " & " " & Err.Number & " " & Err.description & " " & Err.Source & Err.HelpContext

What are the different scripting languages you could use when working with QTP ?

Visual Basic (VB),XML,JavaScript,Java,HTML

How to handle dynamic objects in QTP?

QTP has a unique feature called Smart Object Identification/recognition. QTP generally identifies an object by matching its test object and run time object properties. QTP may fail to recognise the dynamic objects whose properties change during run time. Hence it has an option of enabling Smart Identification, wherein it can identify the objects even if their properties changes during run time. Check this out-
If QuickTest is unable to find any object that matches the recorded object description, or if it finds more than one object that fits the description, then QuickTest ignores the recorded description, and uses the Smart Identification mechanism to try to identify the object. While the Smart Identification mechanism is more complex, it is more flexible, and thus, if configured logically, a Smart Identification definition can probably help QuickTest identify an object, if it is present, even when the recorded description fails.

The Smart Identification mechanism uses two types of properties:
Base filter properties—The most fundamental properties of a particular test object class; those whose values cannot be changed without changing the essence of the original object. For example, if a Web link's tag was changed from to any other value, you could no longer call it the same object. Optional filter properties—Other properties that can help identify objects of a particular class as they are unlikely to change on a regular basis, but which can be ignored if they are no longer applicable.

Explain the keyword createobject with an example.

Creates and returns a reference to an Automation object
syntax: CreateObject(servername.typename [, location])
Arguments
servername:Required. The name of the application providing the object.
typename : Required. The type or class of the object to create.
location : Optional. The name of the network server where the object is to be created.

What is a Run-Time Data Table? Where can I find and view this table?

-In QTP, there is data table used , which is used at runtime.
-In QTP, select the option View->Data tabke.
-This is basically an excel file, which is stored in the folder of the test created, its name is Default.xls by default.

How to do the scripting. Is there any inbuilt functions in QTP as in QTP-S. Whatz the difference between them? how to handle script issues?

Yes, there's an in-built functionality called "Step Generator" in Insert->Step->Step Generator -F7, which will generate the scripts as u enter the appropriate steps.

What is the difference between check point and output value.

An outPut value is a value captured during the test run and entered in the run-time but to a specified location. EX:-Location in Data Table[Global sheet / local sheet]
