tagDESKBANDCID enumeration (shobjidl_core.h)

These command IDs can be sent to the band object's container with IOleCommandTarget::Exec.

Syntax

typedef enum tagDESKBANDCID {
  DBID_BANDINFOCHANGED = 0,
  DBID_SHOWONLY = 1,
  DBID_MAXIMIZEBAND = 2,
  DBID_PUSHCHEVRON = 3,
  DBID_DELAYINIT = 4,
  DBID_FINISHINIT = 5,
  DBID_SETWINDOWTHEME = 6,
  DBID_PERMITAUTOHIDE = 7
} ;

Constants

 
DBID_BANDINFOCHANGED
Value: 0
Updates all bands or a specific band.



  • To update all bands: Set pvaIn to NULL.

  • To update a specific band: Set pvaIn->lVal to the ID of the band to be updated, and pvaIn->vt to VT_I4.

DBID_SHOWONLY
Value: 1
Turns other bands in the container on or off. Set pvaIn->vt to VT_UNKNOWN, and set pvaIn->punkVal to one of the following values.




















ValueResult
pUnkA pointer to the band object's IUnknown interface. The desk band pointed to is shown; all other desk bands are hidden.
0Hides all desk bands.
1Shows all desk bands.
DBID_MAXIMIZEBAND
Value: 2
Maximize the band. Set pvaIn->ulVal to the ID of the band to be maximized, and set pvaIn->vt to VT_UI4.
DBID_PUSHCHEVRON
Value: 3
Version 5. Displays a push chevron on a desk band. Set pvaIn->vt to VT_I4, set pvaIn->lVal to the ID of the desk band, and set the IOleCommandTarget::Exec method's nCmdExecOpt parameter to the band identifier received in the most recent call to IDeskBand::GetBandInfo. The container sends an RB_PUSHCHEVRON message, and the band object receives an RBN_CHEVRONPUSHED notification that prompts it to display the chevron. The band ID is passed back to the band object in the lParam parameter of the RBN_CHEVRONPUSHED message.
DBID_DELAYINIT
Value: 4
DBID_FINISHINIT
Value: 5
DBID_SETWINDOWTHEME
Value: 6
DBID_PERMITAUTOHIDE
Value: 7

Remarks

Set the pguidCmdGroup parameter of the IOleCommandTarget::Exec method to CGID_DeskBand, the pvaIn parameter to the value indicated in the command description, and the nCmdID parameter to one of the command values listed above.
