On Msdn enumerators (Enums) are described as: X++ does not support constants but has an enumerable type (Enum), which is a list of literals. You need to create an Enum in the Application Object Tree (AOT) before you can use it. Enum values are...

Exceptions in Dynamics Ax are quite different than exceptions in .Net. Not only because of the type “System.Exception” and the way you are handling exceptions, but because of the different philosophy on handling exceptions, too. First of all I’d like...

3.1 Changing types (converting and casting) C# is an strongly-typed programming language (even if there are different opinions about this, but coding managed, safe code with C# will fit the definition of a strongly-typed programming language). I quote...

In forms that are using the ActiveX-control ExpressionBuilder (like TrvPolicyForm) you might be faced to the following error message: Method 'initialize' in COM object of class 'IDynamicsAXExpressionBuilder' returned error code 0x80131509 (<unknown>...
