You can retrieve object property values using GetROProperty 
method at runtime.

E.g: retrieves the textbox value into var_Value variable
var_Value = Browser("test").Page("test").WebEdit
("test1").GetROProperty("value")

The question is about the properties in the Object Repository.
So we use "GetTOProperty".

If you want the properties of the object in the application,
then we use "GetROProperty".

RunAction "ActionName",oneiteration,"inputparameter1","input
parameter2","outputparameter"

Note:
1)outputparameter is specified when called action returning 
any value

txt="have a nice day"
t1=ucase(txt)
msgbox(t1)

o/p: HAVE A NICE DAY.

As far as i am aware, there is no keyword for optional 
parameters in VBScripts.

You can achieve this only when you debug the scripts.

Put some break points in your script.
By default the runtime evaluates the variable values upto 
that breakpoint, and from there on to know var. values use 
step in, step out short cut keys.

You can check log file for that.

we should change the object property values in object 
repository

First know which property is changed.
Based on this you need to write descriptive programming to 
identify the object.
Then perform any methods or properties to get the result.

Use "WaitProperty" method for you case.

This method is useful for test run synchronization. Unlike 
the Exist method, the WaitProperty method enables you to 
synchronize the test run based on a specific object 
property. For example, you can instruct QuickTest to wait 
for a particular string to appear in a static text control:
' Wait up to 30 seconds for the string "Ready" to appear in 
the "Status" text control.
Window("Test").Static
("Status:").WaitProperty "text", "Ready", 30000
E.g:

A test scenario is a postulated sequence of possible events.
A test condition is a detailed description of the functional
areas. A Flow may have many variations as per the data
variations. Each flow would be a scenario and each variation
would be a condition.

while u send QTP scripts to ur colleagues send them along
with the object repositories(SAVE THE OBJECT repository and
then send them)

REGRESSION TESTING:
We can check the new functionality of the application have
been incorporated correctly with out failing the existing
functionality.

RETESTING:
We can check the application with difference sets of data is
called.

Re-gression Testing:-which one can perform testing on the
functionality which is already tested before just to make
sure that this functionality is not effected when ever a new
change
(refinement or new addition of the functionality)is added to
the existing funtionality.

Re-testing:-It is conducted on application in order to
ensure the reproducability of an outcome or defect to rule
out environment issues and make to sure that the
fuctionality of an application is rhobust.

When a tester catches a bug he reports it to the 
developer,than after the bug is fixed the retesting is done 
of that new function only.

whereas Regression testing is of the entire system,entire 
system is again tested according to the all conditions used 
at the time of testing.it is done to ensure that the system 
is working fine after the addition of the new function/
corrected bug.

which tells u the object property of that one u have clicked on

object spy is used to view physical or standard properties
of object

Object spy is used to store the properties of objects under 
testing.We can see the physical props like object 
type,name ,..etc in the object description available in 
object spy.

Correct me,if i am wrong

Using descriptive programming, you can set values to the 
textbox with out recording

E.g:
Browser("name:=Google").Page("title:=Google").WebEdit
("name:=Google Serach").Set "Yahoo Groups"

use strrevere.

syntax: strreverse(string name)

Ex: str="Hello Uday"
str1=strreverse(str)
msgbox(str1)

New-->Open-->Fix-->Reopen-->Close.
