If we are working with QTP, we should use the check points
to validate the functionality is working properly or not,
until unless we use descriptive programming.

Any new suggestions???

it is not 100% correct in our company we are using 
checkpoints only to take the values from a data table by 
using standard chkpoint & that too we are not recording it

It is not mandatory to use standard checkpoints available 
with the automation tool. Most of the checkpoints for 
instance Bitmap check points may fail during runtime. 
Instead you can write code to validate what you intend to 
test and then supply a pass/fail log entry to the test 
result wingow.

EG:
check = cbool(trim(Price)=trim(Total))
If check = "True" Then
  reporter.ReportEvent micpass, Total , "Calculation is 
right" 
else
  reporter.ReportEvent micfail, Total , "Calculation is 
wrong" 
End If

In the example mentioned above if value of Total and Price 
are same there will be a pass entry in the test result page 
and if they are not the same then you will have a failed 
log entry in the test results page.

This way you can code for whatever tests you want to get 
validated. Correct me if i am wrong

I have never done validation of images by writing code.
