Deletion and Creation in Sequence Diagram, i need help

I’m new to UML and to Visual Paradigm.
I’m creating some sequence diagrams.
I don’t know how to simulate creation and destruction of lifeline as in the image at this link :

Is that possible in Visual Parafigm ?
And how to make it ?
I don’t know how to make creation because lifeline always start from the top (and not as in the image at the link above from one point that i can decide).
Same thing for the destruction, i don’t know how to simulate the deletion (for example inserting a black cross as in the image).

PS : Sorry for my english and for my explanation, probably not so clear … :oops:

Hello KingNothing,

There are several ways to create <> and <> message:

Creating a <> message
Resource centric interface

  1. Move the cursor to a lifeline. This shows several icons around the lifeline
  2. Press on the one that allows you to create a <> message
  3. Drag to the desired position to create a new lifeline, or to an existing lifeline to create an existing lifeline
  4. Release the mouse button

From diagram toolbar

  1. Select Create Message from the diagram toolbar
  2. Press on the source lifeline
  3. Drag to the target lifeline
  4. Release the mouse button

Creating a <> message
Resource centric interface

  1. Move the cursor to a lifeline. This shows several icons around the lifeline
  2. Press on the one that allows you to create a message
  3. Drag to the desired position or existing lifeline
  4. Release the mouse button
  5. Right-click on the message and select Destroy
  6. Right-click on the lifeline and select Stopped

From diagram toolbar

  1. Select Message from the diagram toolbar
  2. Press on the source lifeline
  3. Drag to the target lifeline
  4. Release the mouse button
  5. Right-click on the message and select Destroy
  6. Right-click on the lifeline and select Stopped

Thanks for the answer.
Very clear and simple ! :wink:

You are welcome! :smiley: :smiley: :smiley:

Excuse me for another newbie question :oops:
I didin’t open a new topic because i prefer to use this one, even if the argument is not on sequence diagrams.

Now i need to build some collaboration diagram.
Some stuff like this : http://img241.imageshack.us/img241/8596/uml2zv8.jpg
How can i make it in VP-UML ?
I see only Communication or State Machine diagram after sequence diagram.
Is it possible to use those tools to make collaboration diagram ?
Or how to make it ?

Thanks in advance for the answer.
Sorry for my “newbieness” and for my bad english … :oops:

Dear KingNothing,

The image you provided doesn’t look like an Activity Diagram. A typical activity diagram should mainly form by actions. It looks something like the one shows here:
http://www.visual-paradigm.com/VPGallery/diagrams/Activity.html

In fact, the image you provided looks more like a communication diagram. Could you clarify on?

Best regards,

You are too much fast at replying :slight_smile:
I have corrected my post in 1 minute but you have already replied.
In my book, it calls that thing “collaboration diagram”.
Is Communication diagram the same thing ?

Hello KingNothing,

You can treat Communication Diagram as an improved version of Collaboration Diagram. In UML 1.x, we have Collaboration Diagram. Starting from UML 2.0, Collaboration is changed to Communication Diagram.

So I believe that you should not find any difficulty in drawing a Communication Diagram like the one show in your image with VP Suite.

If you have any questions, please feel free to let me know.

Best regards,
Jick
