Hello,

What is the equivalen in Visual COBOL to this fragment of code in C#?
        [Category("Data")]
        [Description("Alert Message")]
        public string Message
        {
            get { return message; }
            set { message = value; }
        }

Thanks!

You can do this in a couple of ways.
You will have to add the following namespace import directive to the top of the program or in the project Properties:

$set ilusing"System.ComponentModel"

Since it is defining a simple property that only sets or gets the value of a field you could do this as follows:


01 wsmessage string property as "Message"
       attribute Category("Data")
       attribute Description("Alert Message").


This automatically generates the get and set methods for you.

Or if you needed to change the get or set methods of the property to do something more advanced then you could specify as follows:


01 wsmessage string.
...
method-id set property wsMessage as "Message"
     attribute Category("Data")
     attribute Description("Alert Message").
procedure division using by value the-value as string.
     set wsmessage to the-value
end method.
       
method-id get property wsMessage as "Message"
     attribute Category("Data")
     attribute Description("Alert Message").
procedure division returning the-value as string.
     set the-value to wsmessage
end method.


This is covered in the two example programs under C:\\Users\\Public\\Documents\\Micro Focus\\Visual COBOL 2010\\Samples\\COBOL for .NET\\ called:
CustomAttributes
Properties

You can also find these by opening the Visual COBOL Samples Browser from Start Menu-->All Programs-->Micro Focus Visual COBOL 2010-->Visual COBOL Samples under the COBOL for .NET category.

I have found another issue. After setting the base class and the interface for the new custom user control, I cannot see anymore the design pane. The page says "Unable to show the design pane due to any of these classes cannot be designed" (it is a translation from spanish). If I do the same in C#, the page is shown with no problems.

This is the final code for my user control (it is only a simple test, as you can imagine):

      $set ilusing"System.ComponentModel"
       class-id TestUserControl.cntlCOBOLText is partial
                 inherits type UserControl
                 implements type IDisposable.

       method-id NEW.
       procedure division.
           invoke self::InitializeComponent
           set txtMessage::Text to wsmessage.
           goback.
       end method.

     
       method-id set property wsMessage as "Message"
           attribute Category("Data")
           attribute Description("Alert Message").
       procedure division using by value the-value as string.
           set wsmessage to the-value.
           set txtMessage::Text to wsmessage.
       end method.

       method-id get property wsMessage as "Message"
           attribute Category("Data")
           attribute Description("Alert Message").
       procedure division returning the-value as string.
           set the-value to wsmessage
       end method.
                   
       end class.

       end method.

It looks to me like you lost the following clause on the class-id for the designer class:

inherits type System.Windows.Forms.UserControl.


I created a test user control which looks like yours and when I remove this clause and rebuild the solution and try to display the control in design view I get the same error that you are seeing.

Try adding this clause back and see if it solves the problem for you.

Yes, it works like a charm.

It is strange that C# does not complain about that...

Thank you
