   Set jobCostingObject = CreateObject("JiwaJobCosting.clsJob")
   Set jobCostingObject.Database = JiwaDatabaseObject
   JobNumber = Left(Trim(FormObject.grdStock.Text("JobNo", Row)), jobCostingObject.LengthJobNo)

JiwaFinancials.Jiwa.JiwaJobCosting.Job is a business logic object in that it implements JiwaFinancials.Jiwa.JiwaApplication.IJiwaBusinessLogic you should use the business logic factory on a manager to create one don't just new one up, the read will fail because it will use the manager and hence the database which are not set.

Thanks Stuart, that could be it - have you got a similar example line that you can throw in here ?

Simple replace

Code: Select all

 JiwaFinancials.Jiwa.JiwaJobCosting.Job oJob = new  JiwaFinancials.Jiwa.JiwaJobCosting.Job();     


with

Code: Select all

JiwaFinancials.Jiwa.JiwaJobCosting.Job oJob = goodsRecdNoteEntryForm.Manager.BusinessLogicFactory.CreateBusinessLogic<JiwaFinancials.Jiwa.JiwaJobCosting.Job>(null);   


Thanks Stuart. This helped.
