open a child form and display specifics base on another child form

[icookiprog]

can some help me out with this problem. I am using VB.NET 2005 and SQL 2K.
i have a frmParent which is an MDI form. frmClients and frmCases are the children of frmParent. I have a toolbar on frmParent from which I can open and close the children. What I would like to achieve is when I have the frmClients opens and I am displaying a clientno = 1234 (an identity field) details, I would also like for frmCases to open and go directly to the current client's cases when I click on the open frmCases icon on the toolbar. frmClients will not be visible while I view the cases. It will be visible again when I closed out of frmCases. On the other hand, if frmClients is not open, I would just want frmCases to open and load all the cases ordered by caseno (also an identity field). I am able to do this part. It is opening frmClients, storing the current clientno, passing current clientno to frmContainer (or should it be frmCases? not sure) and opening frmCases to display current clientno cases part that I have no idea how to do. Any help on this is greatly appreciated.
