Hi! I just want to ask if how can I retrieve the dwData or the application defined value in a toolbar button clicking of that button, I read about using TB_SETBUTTONINFO and TB_GETBUTTONINFO, but I do not know where will I place those messages. The toolbar buttons that I have, has custom button idCommand values. I'm working on native implementation of toolbar in Windows. Please help. Thank you.

What are you developing in WinForms, WPF ... or, ? C# ? C++ ?

Are you talking about hooking into lower-level Windows OS behavior here ?

Details, please.

Hi,
I'm developing in Windows Form, its C++ code, I got to read MSDN, but I do not know how can I be able to use those. I just want to know how can I get the dwData value, upon click on the toolbar button. Its is not hooking on lower-level Windows. Below is the code I have:
TBBUTTON tbButtons[] =
{
{ count, IDM_BUTTONSTART + count, TBSTATE_ENABLED, BTNS_AUTOSIZE, {0}, "User defined value", att },
};

I have a couple of buttons to add to the toolbar, each has different dwData value

As with most Windows issues this just requires you to send a message to the component in question. So you send the TB_GETBUTTONINFO message to the toolbar, as described in the documentation for this message[^].
