Make button on commandbar unclickable

Hi

I have a commandbar and i want to show a bitmap on the commandbar when
a function is enabled.

The only way i know how to do this is to hide or show a button.
I do not want the button to become depressed when it is clicked on by
the user. IS there anyway to do this?

I do not want the button to be grayed, so making it disabled is ruled
out.

In the calendar program that comes with any pocket pc, when someone
clicks on date on the commandbar, it is not depressed, or clicked, or
however u wanna describe the button sinking down.

Is there anyway to replicate this behavior?

Thanks a lot for the help!!!

Regards,
Li

Are you saying that you want to display a bitmap on the toolbar, and have
your program be notified when the user clicks on the bitmap?

I can display a bitmap on the toolbar, but i don't want the user to be
able to click on it. As in i don't want the button to sink when the
user clicks on it.

As for how the program reacts, that i can take care of. I just don't
know how to make the button behave the way i want.

Thanks for the help!

In eVC, you can disable a button by using the TB_SETSTATE message to
set the state of the button to 0 (disabled) or TBSTATE_ENABLED. You
can get the HWND (target for the message) from the SHMENUBARINFO
structure used in SHCreateMenuBar. You will need to provide a bitmap
for the disabled state. I do all but the latter; for my purposes,
having a nice icon for the enabled state and a grey box for the
disabled state is sufficient.

Hi, perhaps a better description of my problem would help.

I've tried using a list of images for the disabled button, but nothing
is
shown when the button is made disabled.

I'm adding images to the toolbar using CommandBar_AddBitmap, and then
adding buttons to the commandbar using CommandBar_AddButtons.

The button i'm concerned with is using image of index 0, meaning it is
the
first image added using CommandBar_AddBitmap. How do i set up the
disabled
image list such that the exact same image i added using
CommandBar_AddBitmap will be displayed when the button is disabled?

I used this code:
But nothing shows up when the button is disabled....

HIMAGELIST himlDisabled = ImageList_Create (16,16, ILC_COLOR, 1,10);

HBITMAP hBmp = (HBITMAP) LoadImage(hInst,
MAKEINTRESOURCE(IDB_PLUS_ONE_ICON), IMAGE_BITMAP, 0, 0,
LR_DEFAULTCOLOR);
ImageList_Add(himlDisabled, hBmp, NULL);
SendMessage(hwndButtonBand, TB_SETDISABLEDIMAGELIST, 0,
MAKELONG(himlDisabled, 0));
