radio button member function access

[reneb]

I am placing a radio button in a dialogue box using the resource editor. I want to check its status when the dialogue box closes. There is method called CButton::GetCheck which returns the status of the radio button, but I can't access it because I don't have an object name to use for the call. I can't do radiobuton.GetCheck(); because all I know about my radio button is its ID. How can I access the GetCheck method? Please help. Thanks in advance.

All you have to do is say<br>your dialogname like this :<br>Cdialog1::GetCheck();<br>or CDialog1.GetCheck();<br><br>I cant remember precisely !<br>I hope it helps!<br>&nbsp;<br>

> when the dialogue box closes

That statement is ambigious. If you mean inside the dialog in the WM_CLOSE handler you would do something like this:

// WM_CLOSE message handler
void MainDlg::OnClose()
{
int iVal = -1;
CButton* pBtn = dynamic_cast<CButton*>(GetDlgItem(IDC_BGREY));
if ( pBtn)
iVal = pBtn->GetCheck();

TRACE(&quot;Radio.getCheck returned: %d\r\n&quot;, iVal);
CDialog::OnClose();
}


If you mean from the caller code that created the dialog you would do something like this:

// public member function
int MainDlg::getRadioCheck(UINT id)
{
int nret = -1; // failed to find control 'id'
CButton* pBtn = dynamic_cast<CButton*>(GetDlgItem(id));
if ( pBtn)
nret = pBtn->GetCheck();

return nret;
}

// now in the callers code
void MyFrame::showTestDlg(){

MainDlg dlg;
if ( IDOK == dlg.DoModal()){
TRACE(&quot;MainDlg.radioValue is %d\r\n&quot;,
dlg.getRadioCheck( IDC_BGREY));
}
}

Hope this helps

void CBUTONDlg::OnButton1()
{
int i;

i = GetCheckedRadioButton(IDC_RADIO1, IDC_RADIO3);

switch(i)
{
case IDC_RADIO1:
strcpy(str1 , &quot;Radio1&quot;
break;
case IDC_RADIO2:
strcpy(str1 , &quot;Radio2&quot;
break;
case IDC_RADIO3:
strcpy(str1 , &quot;Radio3&quot;
break;
default:
strcpy(str1 , &quot;(Seçili öge yok) Nothing Selected!&quot;
break;
}
AfxMessageBox (str1);
}
