TBN_GETBUTTONINFO
The
TBN_GETBUTTONINFO message retrieves toolbar customization information and
notifies the toolbar s parent window of any changes being made to the toolbar.
This is sent in the form of a WM_NOTIFY message.
TBN_GETBUTTONINFO
ptbn = (TBNOTIFY FAR *) lParam;
Parameters
ptbn
Pointer to a TBNOTIFY structure. The iItem
member specifies a zero-based index that provides a count of the buttons the
customize dialog box displays as both available and present on the toolbar.
The pszText
member specifies the address of the current button text, and cchText
specifies its length in characters. The application should fill the structure
with information about the button.
Return Values
Returns TRUE
if button information was copied to the specified structure or FALSE otherwise.
Remarks
The toolbar
control allocates a buffer, and the receiver (parent window) must copy the text
into that buffer. The cchText member contains the length of the buffer
allocated by the toolbar when TBN_GETBUTTONINFO is sent to the parent window.
