CToolBarCtrl::AddBitmap 

Adds one or more button images to the list of button images stored in the toolbar control.


int AddBitmap(
   int nNumButtons,
   UINT nBitmapID 
);
int AddBitmap(
   int nNumButtons,
   CBitmap* pBitmap 
);

Parameters

nNumButtons

Number of button images in the bitmap.

nBitmapID

Resource identifier of the bitmap that contains the button image or images to add.

pBitmap

Pointer to the CBitmap object that contains the button image or images to add.

Zero-based index of the first new image if successful; otherwise – 1.

You can use the Windows API CreateMappedBitmap to map colors before adding the bitmap to the toolbar. If you pass a pointer to a CBitMap object, you must ensure that the bitmap is not destroyed until after the toolbar is destroyed.
