Recently, in the MFC Ribbon button write function, accidentally added a new button and response function, found that the execution is another function!

=======================================================================

Let me try to reproduce and fix it.

=======================================================================

New MFC Program

The other uses the default settings.

Operating effect:

=======================================================================

The default ribbon:

=======================================================================

Here's what you'll start adding ribbon.

Add a category, default is Category 1, and by default there is a panel of 1. Add button Button1.

Here to see the attribute, found that the ID is actually id_button2. I don't know why, is it my vs problem? But I am also in another virtual machine environment.

=======================================================================

Rename Id_button2 to id_btn_t, and change the title to T. Add the function onbtnt.

void cmainframe::onbtnt (){// TODO: Add Command handler code in this 4 MessageBox (TEXT ("onbtnt")) ; 5}         

Run, normal.

=======================================================================

Back up the project.

=======================================================================

Add 1 new buttons and a separator. But the ID of the button is Id_button2 and the title is Button1.

I changed it to id_btn_wls. Change the title to WLS.

The same add function.

void cmainframe::onbtnwls (){// TODO: Add Command handler code 4 in MessageBox ("onbtnwls" )); 5}         

Run, success. There is no problem with the function response.

=======================================================================

It's starting to build!

=======================================================================

Change Id_btn_wls to Id_btn_tt.

Try right-clicking Add function and find "add Edit" button is available!

Incredibly can add, then add one.

void Cmainframe::onbtntt (){// TODO: Add Command handler code 4 in MessageBox ("onbtntt"  )); 5}         

Now compile the link to run the program and find that the click Is TT, but the response function is onbtntt!

=======================================================================

Watch Resource.h File

Discover the last two IDs are the same! Of course, it must be the same! Because just changed the ID name, and did not delete or add the ID, so MFC just added a macro to map to the corresponding control ID.

But since the second one is newly added, there is no mapping function, so right-click can add the upper function.

To verify this idea, take a look at the mapping macro in MainFrm.cpp.

I'm now going to change the order of the Code in the box.

The result of the execution is correct:

Now it seems that the code should be removed from this situation, i.e. the following code is removed:

#define ID_BTN_WLS                      32772

1 On_command (id_btn_wls, &cmainframe::onbtnwls)

void cmainframe::onbtnwls (){// TODO: Add Command handler code 4 in MessageBox ("onbtnwls" )); 5}         

void Onbtnwls ();

=======================================================================

You think this is over? It's not that simple!

Open the project you just backed up and recreate it once!

=======================================================================

Not to be continued.
