Radio Button Query.

[cagespear]

I have an MFC Dialog which houses 3 radio buttons. I want to take some action only when user selects radio button which is not selected already so that I don't perform the same set of actions if a user RE-Selects a radio button. Can someone advise me what's the best way to achieve this ? Thanks Cage

Hi, You mean when clicking the same radio button again and again or when selecting a button and change to other again come back to previous button? In second case, you can set a static variable like static bool bAlreadySelected = true when the button clicked already it will be true. Otherwise perform the set of options. Set the above variable to false at startup of dialog. This is one way. There may be some other way too. Thanks, Suman

No Suman, that doesnt solve my problem. I want to take a certain action everytime the control is transferred from the other radio button, not just for the first time. Let me be more clear. Example - Three radio buttons be A, B and C. I want to perform certain operations everytime user has selected A or B and then he clicks C, but I don't want to take any action if user re-selects C.

That's not very complicated: in your class declare an integer variable (e.g. m_currentSelected). On each of your radio button handler functions, assign a value to this variable (e.g. 1 for the first radio button, 2 for the second, ...). It is easier with code:

void CMyClass::OnRadio1Clicked()
{
if(m_currentSelected==1)
return;

// Do stuff....

m_currentSelected = 1;
}

Thanks Cedric. This helps, I was thinking on these lines but felt that may be if through MFC we can achieve this ?
