Hi,

 

I'm trying to implement async processing.  I've added Async = 1 to my transaction object and added a comment to the retrieve row event of my inherited datawindow control object.  At execution time, I get the following error on the 8th row(8th time retrievrow is called) every time. 

 

"Only the cancel command is allowed when the rows are pending."

 

based on the error I was thinking Async wasn't actually being enabled.  I tried a using a separate transaction object, checking the Asyc dbparm in the transaction object before retrieve and it looks enabled.  Am I missing something?

 

Thanks!

 

Joel
