How do I use Radio Buttons (and checkboxes)?

[Ragnar]

I have added 2 radio buttons on my form. What is the code for checking which radiobuttons are true?
Oh and can you guys please say the code for checking which checkboxes are true?

Thanks.

You can use

IsDlgButtonChecked
The IsDlgButtonChecked function determines whether a button control has a check mark next to it or whether a three-state button control is grayed, checked, or neither.

UINT IsDlgButtonChecked(
HWND hDlg, // handle to dialog box
int nIDButton // button identifier
);

Parameters
hDlg
Handle to the dialog box that contains the button control.
nIDButton
Specifies the integer identifier of the button control.
Return Values
The return value from a button created with the BS_AUTOCHECKBOX, BS_AUTORADIOBUTTON, BS_AUTO3STATE, BS_CHECKBOX, BS_RADIOBUTTON, or BS_3STATE style can be one of the following:

Value Meaning
BST_CHECKED Button is checked.
BST_INDETERMINATE Button is grayed, indicating an indeterminate state (applies only if the button has the BS_3STATE or BS_AUTO3STATE style).
BST_UNCHECKED Button is unchecked


If the button has any other style, the return value is zero.

Remarks
The IsDlgButtonChecked function sends a BM_GETCHECK message to the specified button control.

if( SendMessage(hwndRadio, BM_GETSTATE, 0, 0) == BST_CHECKED)
    // Button is checked
