I'm new in ax and have a problem

I have a form with diffrent entries (Id, Name etc..) and a Button.

Click on the button will open a new class to calculate.

Now I want to get the current id, form the form to the class.

click Method:

void clicked()

{

NewClass newclass; ; super();

NewClass ::new("Id123");

newclass.method();

}

The string of "id123" should be the current id from the form, i have selected.

If i use select table.. I will get any id, and not the selected. The class have a parm method with a parameter.

Hey Littleben,

I think you can use the DictClass class for your request.

It gives you the possibility to call classes on a dynamical way.

This example in the link gives you a good start:

msdn.microsoft.com/.../dictclass.callobject.aspx

Greetings,

BTW: A form doesn't have an ID.

So your approach to send a parameter to let the class know what form was used needs to be via a different property.

A form can be called via the ClassFactory.formRunClass method.

The parameter for this method are Arguments which needs to be filled with a formName.

Your clicked() method should look more like this:

void clicked() { NewClass newClass = new Class(); newClass.parmId(CurrentId.text()); newclass.method(); }

The code assumes that the form control is called CurrentId and you've set its AutoDeclaration property to Yes.

But if the control is bound to a data source (as "If i use select table" suggests), you could pass the whole record and maybe avoid any code in clicked() by moving it to main() method of the class. Please tell us whether the control is linked to a database field or not.
