I assume your button is on the dialog, so CToolBarCtrl::HideButton isn't of any use. You need to use ShowWindow to hide the button control, something like this: CMyDialog::M1() { ..... GetDlgItem(IDC_BUTTON1)->ShowWindow( SW_HIDE ); Since you need to control this from the invocation, I suggest that you add a boolean public member variable to your dialog class and set it appropriately at the point where you invoke the dialog, then test it in your dialog's OnInitDialog handler and conditionally hide your button.

Create a control variable for your button; then you can write c_MyButton.ShowWindow(show ? SW_SHOW : SW_HIDE); or something like that.
