NMTBRESTORE structure (commctrl.h)

  • Article

Allows applications to extract the information that was placed in NMTBSAVE when the toolbar state was saved. This structure is passed to applications when they receive a TBN_RESTORE notification code.

Syntax

typedef struct tagNMTBRESTORE {
  NMHDR    hdr;
  DWORD    *pData;
  DWORD    *pCurrent;
  UINT     cbData;
  int      iItem;
  int      cButtons;
  int      cbBytesPerRecord;
  TBBUTTON tbButton;
} NMTBRESTORE, *LPNMTBRESTORE;

Members

hdr

Type: NMHDR

NMHDR structure that contains additional information about the notification.

pData

Type: DWORD*

Pointer to the data stream with the stored save information. It contains Shell-defined blocks of information for each button, alternating with application-defined blocks. Applications may also place a block of global data at the start of pData. The format and length of the application-defined blocks are determined by the application.

pCurrent

Type: DWORD*

Pointer to the current block of application-defined data. After extracting the data, the application must advance pCurrent to the end of the block, so it is pointing to the next block of Shell-defined data.

cbData

Type: UINT

Size of pData.

iItem

Type: int

Value of -1 indicates that the restore is starting, and pCurrent will point to the start of the data stream. Otherwise, it is the zero-based button index, and pCurrent will point to the current button's data.

cButtons

Type: int

Estimate of the number of buttons. Because the estimate is based on the size of the data stream, it might be incorrect. The client should update it as appropriate.

cbBytesPerRecord

Type: int

Number of bytes needed to hold the data for each button. When the restore starts, cbBytesPerRecord will be set to the size of the Shell-defined data structure. You need to increment it by the size of the structure that holds the application-defined data.

tbButton

Type: TBBUTTON

TBBUTTON structure that contains information about the button currently being restored. Applications must modify this structure as necessary before returning.
