Clear Checkbox??

[Aoife]

I have two checkboxes. The second becomes enabled when the first is checked and disabled when the first is unchecked, but I also need the second to be unchecked automatically when the first is unchecked by the user. The following code disables the second but doesn't clear it. *********************************************************** void CTab3_SMS::OnSaveToPCcb() { //Get the current values from the screen UpdateData(TRUE); //Is the "FIRST" checkbox checked? if (m_bSaveToPC == TRUE) { //Enable the "SECOND" checkbox GetDlgItem(IDC_DELETEFROMSIMCB)->EnableWindow(TRUE); } else { //No; clear and disable the "SECOND" checkbox GetDlgItem(IDC_DELETEFROMSIMCB)->EnableWindow(FALSE); } } *********************************************************** What other command goes into the else{} statement? Thanks, Aoife

CheckDlgButton (IDC_FOO, FALSE);

You're absolutely right. It should be CheckDlgButton (IDC_FOO, BST_UNCHECKED). /ravi "There is always one more bug..." http://www.ravib.com ravib@ravib.com
