hi to all,

This is regarding chat private messaging.

I have a list of users online on my site, Once I dblclick one of them then the new div window will popup which is I've already done. My problem now is, once I already type a message and enter, how another div window will popup to the pc of the user I was hit. I don't know how to start. I have no idea how to do this. First thing trouble in my mind is, how can I sense that this window should popup to the specific user pc?

Any idea or suggestions

Thanks in advance

You can't force users to have a window pop up on their computer unless they specifically allow you to, since virtually every modern browser has a popup blocker installed on it. The only time popups are allowed is in response to a click these days. Of course, users are allowed to make exceptions to this, but I suspect it is hard to get this to happen.

The solution is to fake a popup with a modal popup (which acts like the well-known "lightbox").

The other problem with the scenario you're describing, is that you can't just ping any user you like without programming their browsers to be constantly listening for a new command. You'll have to make the browsers "listen" for a new window by querying some external page via AJAX inside of a setInterval() function which does a command repeatedly at a set interval.
