Obtaining and Setting a Checkbox State

Does anyone know how to get the Checkbox state, if it is NOT in a dialog box? I have this code, but its not working..

Code:

---

        case WM_COMMAND:
                {
                        switch(LOWORD(wParam))
                        {
                        case IDC_START:
                                {
                                        UINT cLogoff;
                                        cLogoff = IsDlgButtonChecked(hLogoff, IDC_LOGOFF);
                                       
                                        if(cLogoff == BST_CHECKED)
                                        {
                                                CheckDlgButton(hShutdown, IDC_SHUTDOWN, BST_UNCHECKED);
                                                CheckDlgButton(hRestart, IDC_RESTART, BST_UNCHECKED);
                                                bLogoff = true;
                                                bShutdown = false;
                                                bRestart = false;
                                        }
                                }
                                break;
                        }
                }
                break;

I think that BST_CHECKED is a flag that is part of a mask, so doing this:

cLogoff == BST_CHECKED

isn't necessarily going to be true (depends on the rest of the mask).

so try this:

Code:

---

if(cLogoff & BST_CHECKED)
{
  // do stuff
}

good luck
U.

I use that macro, in the way you used it, without problem.

Is that case statement entered if you click the radio button? (are the msg's going to this callback)

>>IsDlgButtonChecked(hLogoff, IDC_LOGOFF);

Is hLogoff the parent HWND (as it should)
or
the buttons HWND (which it shouldn't, but looks like)?



EDIT: This is my 1000 post, do I get a GovtCheese doll or something?

> Is hLogoff the parent HWND (as it should)
Ohhh its the hWnd of the button.

What does the & operator do? check to see if its true?
[EDIT] Nevermind, i think i know what it does, but if im wrong you can still correct me :), does it: Check to see if that flag is part of it?
example:

Code:

---

UINT uInt;
uInt = BLAH_BLAH | HALB_HALB;

if(uInt & BLAH_BLAH)
    MessageBox(NULL, "BLAH_BLAH IS SET", "Information", MB_OK);
