Buttons of toolbar

[andriasoa]

How I can disable, enable or gray a button of a toolbar
during the program?
(I can do it during creation of the toolbar).

I have (T_TBBUTTON) TBbutton(21)

I try to use type SendMessage with one of the three following parameters :
TB_ENABLEBUTTON
TB_SETSTATE
TB_INDETERMINATE
No result

for example : to disable the button 2 of a toolbar

iret = SendMessage(hWndTB, TB_ENABLEBUTTON, 2, FALSE)

to gray the button 2 of a toolbar

iret = SendMessage(hwndTB, TB_INDETERMINATE, 2, TRUE)

iret = SendMessage(hWndTB, TB_SETSTATE , 2, MAKELONG(TBSTATE_INDETERMINATE, 0))

Thanks,

wParam of TB_ENABLEBUTTON should be button ID (the same value you put in T_TBBUTTON.idCommand), not its index.
