How do I set up my own message in message map?

[DHunter21]

Hi,

I want to setup my own message (MM_REFRESH), and I don't know what exactly to do. Funny how none of my 5 books say anything on this.. hehe.

Anyways, I thought that I should enter
afx_msg void OnRefreshTerm();
to the message map in the header file. I then thought I should add ON_MM_REFRESH() to the message map in the cpp file.

What am I doing wrong here? I want MM_REFRESH to execute OnRefreshTerm().
Iwould also like to know what the proper way to call the message is. (ie this->SendMessage(MM_REFRESH, ???, ???);

Thanks

In the message map you should put:

ON_MESSAGE(MM_REFRESH, OnRefreshTerm)

HTH,

MFC doesn't know about your message, so it's not going to have a pre-defined macro (#define) called ON_MM_REFRESH. Instead, you have to use ON_MESSAGE in your message map, like this:
ON_MESSAGE(MM_REFRESH, OnRefreshTerm)


If you are sending from the saying object (sending to "this"), then just call SendMessage(MM_REFRESH, ...). The other two parameters depend on what the function that handles the message expects for wParam and lParam.

Hope this helps,
Brad

The first thing you want to do is to place a constant that represents the message in the overall header file:
#define WM_REFRESH (WM_USER+1)
Next connect the message to the handler with the macro in the message map:

BEGIN_MESSAGE_MAP(.. , ..)
ON_MESSAGE(WM_REFRESH,OnRefresh())
END_MESSAGE_MAP()

Lastly, place prototype of OnRefresh in the class header and write the fuction itself.

Enjoy........
