How do I put 30 buttons in a Dialogbox with all button presses handled by the same function

[Jason Watson]

I want to put 30 buttons on a Dialog box. I need to know how to create an array of CButtons so that I can access all the controls with the same member variable. I also need to be able to process button presses using the same function

Similar to the way VB does it.

Hi!
1. Put in the 30 buttons on to your dialog box ensuring in the process that the IDs are contiguous.
2. Add the following message map entry in your dialog
ON_CONTROL_RANGE(BN_CLICKED,IDC_BUTTON1,IDC_BUTTON30,HandlerForBtnPress)
3. Add the prototype and the implementation of the BN_CLICKED Handler
//Prototype in the header file
afx_msg void HandlerForBtnPress(int nID);
//Sample implementation in the cpp file
void CTrialDialog::HandlerForBtnPress(int nID)
{
int nButton = nID - IDC_BUTTON1;
CString strMessage;
strMessage.Format("Button %d Clicked !!!",nButton);
AfxMessageBox(strMessage);
}
This ensures that the same function handles all button presses.

Incase you need to create an array of CButtons, here is the code for it :
//Header File
const int nradio_buttons = 30; //Number of buttons
//Class Definition
CButton* m_ButtonArray[nradio_buttons];
//OnInitDialog
for(int i=0;i<30;i++)
{
m_ButtonArray[i] = (CButton*)GetDlgItem(IDC_BUTTON1+i);
}
//Make use of m_ButtonArray[i] for further processing as U need.

Try the following
ON_CONTROL_RANGE( BN_CLICKED,ID_BUTTON_01,ID_BUTTON30,ButtonCatcher )

MyClass::ButtonCatcher()
{
// TODO: add logic (maybe a switch statement)
}
