How can I get the state of a checkbox? (checked , not checked)?

Hi realcr,

Invoke SendMessage, hWnd, BM_GETCHECK, 0, 0


hWnd = Handle for the check box


It returns BST_CHECKED (1) or BST_UNCHECKED (0) in Register Eax.

Regards,

Ramon

Hi realcr,
Be sure to read up about this topic in the win32.hlp file.  In addition to rsala's method, which works fine you can use The IsDlgButtonChecked function to determines whether a button control has a check mark next to it or whether a three-state button control is grayed, checked, or neither.
