Thread: 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

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);

[/EDIT]

yup, correctamundo.
