The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

PowerBuilder App Exec Error (R0002) - Null object reference

Asked by P_Robinson in Sybase Database

Tags: , , , ,

We have a customer who is using an older version of PowerBuilder (5.0).

There current application was written for them by a company they are no longer able to approach and they have asked me to try and resolve a couple of errors that they are getting.  My exposure to PowerBuilder is very limited (to be generous!) but I was hoping to be able to help them out of a hole.

One of these is the above error, with the message "Error:  Null object reference at line 6 in clicked event of object cb_10 of w_prop_maint."

The code for this is:

1.   str_chosen_address a
2.  
3.   Open(w_postcode_browse)
4.
5.   a = Message.PowerObjectParm
6.   if a.Postcode <> '' then
7.        // User has chosen an address
8.        dwc_prop.Object.property_t_address_1[1] = a.addr1      
9.        dwc_prop.Object.property_t_address_2[1] = a.addr2      
10.        dwc_prop.Object.property_town[1] = a.town      
11.       dwc_prop.Object.property_county[1] = a.county      
12.       dwc_prop.Object.property_t_postcode[1] = a.postcode
13. end if

Can anyone help me identify the cause?

Cheers
