Call value from form to class using args

put following code on class method


 void initFromArgs(Args args)  
 {  
 ;  
 if (args && args.dataset() == tablenum(abcform))  
 {  
 abcForm = args.record();  
 salesOrder = abcForm.SalesId;  
 qty = abcForm.Qty;  
 }  
 }  
then you can call this method to main method.
