TBREPLACEBITMAP structure

Used with the TB_REPLACEBITMAP message to replace one toolbar bitmap with another.

Syntax


typedef struct {
  HINSTANCE hInstOld;
  UINT_PTR  nIDOld;
  HINSTANCE hInstNew;
  UINT_PTR  nIDNew;
  int       nButtons;
} TBREPLACEBITMAP, *LPTBREPLACEBITMAP;

Members

hInstOld

Type: HINSTANCE

Module instance handle to the bitmap resource being replaced. Set this member to NULL to instead use a bitmap handle.

nIDOld

Type: UINT_PTR

If hInstOld is NULL, set this member to the bitmap handle of the bitmap that is being replaced. Otherwise, set it to the resource identifier of the bitmap being replaced.

hInstNew

Type: HINSTANCE

Module instance handle that contains the new bitmap resource. Set this member to NULL to instead use a bitmap handle.

nIDNew

Type: UINT_PTR

If hInstNew is NULL, set this member to the bitmap handle of the bitmap with the new button images. Otherwise, set it to the resource identifier of the bitmap with the new button images.

nButtons

Type: int

Number of button images contained in the new bitmap. The number of new images should be the same as the number of replaced images.

Remarks

If nIDNew holds a bitmap handle, rather than a resource ID, do not destroy the bitmap until it has been replaced with TB_REPLACEBITMAP, or the toolbar is destroyed.
