WTL User Defined Message

[damir_tk]

Hi everybody. Can somebody please help me with this? I have a dialog that I use embedded in the tab control, that is on the main dialog. I want to send a user defined message (or is there a better way?) to notify the parent dialog to hide-show itself. How do I go about this? Thanks.

You send a user defined message using SendMessage() or PostMessage(). You define a message using #define.

Thanks, I know that. But the parent dialog does not intercept the message, as I have REFLECT_NOTIFICATIONS defined, so it doesn't work.

Define a message ID in the WM_APP range, like this:

#define UWM_SHOW_HIDE_MAIN_WINDOW WM_APP

Then in your child dialog:

GetTopLevelParent().SendMessage(WM_APP, show_or_hide_flag);

Or you could break it into two messages, one for showing and one for hiding. Handle UWM_SHOW_HIDE_MAIN_WINDOW in your main dialog's message map and show/hide the window accordingly.

Why don't you get rid of REFLECT_NOTIFICATIONS?

[damir_tk]

I can not, because I am using a derived class to embed my dialog class into the tab control, so I need to reflect the messages. Thanks.

Thanks Mike, you are as helpful as always. I ran through all of your articles about WTL, but couldn't figure this GetTopLevelParent() out. Thank again.
