Changing button name MFC Visual Studio

I just started the GUI development, i had started on C++Builder but i switched to Visual Studio for differents reasons. But in Visual Studio, i've got a big problem :

In the GUI development interface (rc file) i can create buttons and place it, but i can't change there names. The name for all of MFC components i placed is initialize to a default name which i can't call and i can't change the property by the properties interface, i can change the Text, for change the Label of the Button, but not the name... It's very incomfortable because by that i can't call my buttons for do anything, i have the same problem for Listboxs, so i can't modify my list because i can't call there

I just want to modify access my component by my c++ code for modifying this component

enter image description here

Thank for your help !

The MFC way of doing event handling is a bit more elaborate. After the control is created on the form in the designer, an ID is generated ("IDC_BUTTON1" in the attached screenshot). This is the ID that will be used for accessing this UI control from the code.

All this can be done via the designer also as shown in this article.

Basically, in the background this generated ID is put in a 'message map' (more about message maps here). In short 'message map' is used to specify what action needs to be performed when a certain type of action is done on the UI control by the user. For, example if the button click is to be handled then in code: the message map would look like:

BEGIN_MESSAGE_MAP(CSurface3DView, CView)
  ON_BN_CLICKED(IDC_BUTTON1, CallMyFunction)
END_MESSAGE_MAP()

'ON_BN_CLICKED' is a predefined event macro.

The 'CallMyFunction()' function has to be declared with 'afx_msg' in the class. Besides please, have a look at data exchange mechanism as well. This know-how about data exchange will come in handy going forward.
