Re: [development-axapta] Problem with args's class

[Jonathan St-Louis]

Both of your explaination helped me to found a solution to my problem.  The only thing that was missing is because I wanted to use that value in the the form called.  It's because I didn't think that the class was created in the report.  Stupid error from me.  But I wasn't sure if how work classes with contruct and main anyway, so it helped me a lot.
 

Thanks!

Hi!

You can't access variables declared in classDeclaration in static-methods, i.e 
construct and main.
In a static method you need to create an instance of the class that you want to use, 
and then use that classes methods.
If you wabt to use variables from e.g a form, these variables has to be passed to the 
class.
An example:

You have a class CustUpdate, with a classdeclaration, a main(Args _args)- method and a updateCustomer(CustAccount _custAccount)-method.

The class is supposed to update a customer where custAccount equals the value passed from the args-object

If you run this from a menuitem, the main-method is executed:

static void main(Args _args)
{
   CustUpdate custUpdate = new CustUpdate(); // Create instance
   CustAccount custAccount;
   ;
   
   if (custUpdate && _args.parm())
   {
       custAccount = args.parm();
       custUpdate.updateCustomer(custAccount);
   }
}

void updateCustomer(CustAccount _custAccount)
{
   CustTable custTable;
   ;
   
   ttsbegin;    
   if (custAccount)
   {
       custTable = CustTable::find(custAccount, true);
       custTable.Name = "New name"; // Update something
       custTable.update();
   }
   ttscommit;
}

Subject: [development-axapta] Problem with args's class

Hi, I would like to pass value from one form to another.  
Unfortunatly, the value must pass trought classes because the called 
form is called with a menuItem-->Action.  When I pass the value with 
the args.parm() of the menuItem to the class, I lost the value.  I 
can access it in the construct and main method of the class, but 
after that, I lost it.  Also, in the Construct and Main method, I 
can't access variables in the classDeclaration neither the other 
method of the class.  

Can anyone can explain me why?  Help is greatly needed here and if 
you don't understand what I want, please ask me to re-explain.

Thanks!
