I need to return values from open window to user object without close current window

I have user object hold datawindow , i need to open other window to search on it and make some operation then insert in开发者_开发问答 datawindow on user object without close window.

I think of two possibilities :

Direct access (quick and dirty) :

• You could open the second window with OpenWithParm() and give the datawindow as argument.
• In the open() event of that second window, you can get that datawindow via Message.PowerobjectParm
• insert what you need to in the given DW.

Better way (decoupling the process and the GUI) :

• add a dedicated method to the first window that accesses directly the DW
• use OpenWithParm() with this as argument to let the second window who is calling it
• get the caller with the Message.PowerobjectParm
• call the dedicated method of the caller to add data into the DW
