Bonus TIPS for Successful Posting

Try a Search First
It is highly recommended that a Search be done on your topic before posting, as many questions have been answered in prior posts. As with any search engine, the shorter the search term, the more "hits" will be returned, but the more specific the search term is, the greater the relevance of those "hits". Searching for "table" might well return every message on the board while "tablesum" would greatly restrict the number of messages returned.

When you do post
First, make sure you are posting your question in the correct forum. For example, if you post an issue regarding Desktop applications on the Mobile & Browser Applications board , not only will your question not be seen by the appropriate audience, it may also be removed or relocated.

The more detail you provide about your problem or question, the more likely someone is to understand your request and be able to help. A sample database with a minimum of records (and its support files, zipped together) will make it much easier to diagnose issues with your application. Screen shots of error messages are especially helpful.

When explaining how to reproduce your problem, please be as detailed as possible. Describe every step, click-by-click and keypress-by-keypress. Otherwise when others try to duplicate your problem, they may do something slightly different and end up with different results.

A note about attachments
You may only attach one file to each message. Attachment file size is limited to 2MB. If you need to include several files, you may do so by zipping them into a single archive.

If you forgot to attach your files to your post, please do NOT create a new thread. Instead, reply to your original message and attach the file there.

When attaching screen shots, it is best to attach an image file (.BMP, .JPG, .GIF, .PNG, etc.) or a zip file of several images, as opposed to a Word document containing the screen shots. Because Word documents are prone to viruses, many message board users will not open your Word file, therefore limiting their ability to help you.

Similarly, if you are uploading a zipped archive, you should simply create a .ZIP file and not a self-extracting .EXE as many users will not run your EXE file.

    Hi Michael,

    I don't see in your function where you are creating the args variable ex: dim args as sql::Arguments

        Thanks all for your help. I found the problem: ndx was returning 0 due to an incorrect pointer and that threw the whole thing off.

          To be more specific I first made this call to get information about a product:
          Code:
          sqlStatement = "SELECT * FROM cart_products WHERE id={prod_id}"
          sqlStatement = evaluate_string(sqlStatement)
          dim arr_prod[0] as p
          cnAbleHire.topropertyarray(sqlStatement,arr_prod)
          In this case (WHERE id={prod_id}) ID was changed in the table so no results were found and I ended up with a NULL property array.
          So when I made this call, it effectively blew up with an unhandled exception c0000005:
          args.add("item_title",arr_prod[1].item_title)

          Once I put the correct ID in the table, the info was found and no errors occured.

          Maybe this Unhandled Exception could be handled in an update to ver11? (hint hint)

            Handled? What is Alpha going to do to stop you from generating an unhandled exception? Always check your data before you try to use it.

            Code:
            if (arr_prod.size() == 0) then 
              OOPS("arr_prod is empty!",e)
              end
            end if
            
            if (ndx < 1 .or. ndx > arr_prod.size()) then
              OOPS("ndx out of bounds",e)
              end
            end if

              An Unhandled Exception means that a runtime error occured in alpha's code and no error handler was written to catch the error. That should never happen.

              I do like:
              if arr_prod.size() = 0

              I hadn't considered that as part of my own error trapping.
