m_toolbarCtrl = 0;

m_toolbarCtrl = new CToolBarCtrl;

CRect rc(0,0,wndRect.right,50);

m_toolbarCtrl->Create(TBSTYLE_TOOLTIPS | WS_CHILD | WS_VISIBLE | CCS_NODIVIDER,rc,this,100);

m_toolbarCtrl->AddBitmap(3,IDB_BITMAP1);

btn[0].iBitmap = 0;

btn[0].idCommand = ID_BLACK;

btn[0].fsState = TBSTATE_ENABLED;

btn[0].fsStyle = TBSTYLE_BUTTON;

btn[0].dwData = 0;

btn[0].iString = 0;

btn[1].iBitmap = 1;

btn[1].idCommand = ID_RED;

btn[1].fsState = TBSTATE_ENABLED;

btn[1].fsStyle = TBSTYLE_BUTTON;

btn[1].dwData = 0;

btn[1].iString = 1;

btn[2].iBitmap = 2;

btn[2].idCommand = ID_BLUE;

btn[2].fsState = TBSTATE_ENABLED;

btn[2].fsStyle = TBSTYLE_BUTTON;

btn[2].dwData = 0;

btn[2].iString = 2;

m_toolbarCtrl->AddButtons(3,btn); //添加一个 TBBUTTON
