abhishekpareek

Hi All,
I am new to axapta but I had worked extermely in Navision for 5 years.
I had installed axapta 4.0.I have to develop a connector in Axapta that will call some c# functions.
The scenarion is as follows:
1:Create a Menu Item.

Issue:How to create a menu item in Axapta.
Assumption:should I have to use Application Server i.e AOS?

2:After creating a menu item,I have to put four options in that.Each option will call the functions from c# application.

Issue:
a)How to create buttons in Menu Item.
b)How to call the functions from c# application in menu item.

Assumption:For the third party application I would be having a dll file and that file needs to be place in Axapta folder.
Now how to call the functions from dll file in axapta menu items.

It would be great of anybody if some light can be given over the issues.

Regards,
Abhishek
