Re: transparent PNG for toolbar

here's how it's done using GDI+

// somewhere after CreateSimpleToolBarCtrl is called...
Gdiplus::Bitmap* gbm = Gdiplus::Bitmap::FromFile(L"res\\test.png");
Gdiplus::Color clr(Gdiplus::Color::Transparent);
HIMAGELIST hImageList = ::ImageList_Create(16, 16, ILC_COLOR32, 5, 1);
HBITMAP inner = 0;
gbm->GetHBITMAP(clr, &inner); // this must be destroyed
::ImageList_Add(hImageList, inner, 0);
::SendMessage(hWndToolBar, TB_SETIMAGELIST, 0, (LPARAM)hImageList);
delete gbm;

so the idea is to create a new imagelist from the png and set it to the toolbar. It works from windows XP onwards
