A raw toolbar for Dialog and Property page with plenty nice styles

Download source program (version 1.01)

Update information

Only new features and bug-fixed are displayed bellow.
Please visit previous version 1.00 for more information.

FunctionCreate() function has been changed to:
BOOL Create(CWnd*pMum,int iBmpID,int cx,int iBarID=-1,COLORREF clrBkgnd=RGB(192,192,192));
In version 1.00, the function is:
BOOL Create(CWnd*pMum,int iBmpID,int cx,int iBarID=-1);

clrBkgnd : transparent color of bitmap resource, similar to the color in CImageList

I developed 1.00 on Win98, but when I tested on XP, I found the problem: bitmap background is not transparent to COLOR_BTNFACE, this parameter allows to fit the color to COLOR_BTNFACE - automatically done by CImageList.
MessagesA new message is added to the toolbar:
If user right clicks a button, the new message is distribute to parent window.

To process multiple messages in parent widow, a message class has to be used.
Message signature is:
message: WM_COMMAND, wParam: toolbar's ID (same as in version 1.00).
lParam: a pointer to class ToolbarMine::Message.

The inner message class contains following members:
class Message
{
public:

UINT uMessage; //see bellow

int iIndex; //index of the button clicked

CRect rcButton //rectangle of the button clicked
};

uMessage has 2 cases:
1. WM_LBUTTONDOWN
  It is the same as the only message in version 1.00.
  Please note:
  The message is actually distributed at WM_LBUTTONUP for independent buttons.
  It is almost unnecessary to define new message constant, so I simply use this existing Windows constant.
  This is similar to Windows' common buttons, which tell us a button is clicked rather than down or up.
2. WM_RBUTTONDOWN
  The message is distributed when user clicks a button by right-button of mouse.
  Right-clicking a button does not change button situations (checked or pressed) at all.
  
  The message allows us to do some interesting things with it.
  In my application (not sample program), I display a popup menu associated with the message, which contains "Help", "Edit", "Submit" and "Close" menu items, so my application can offer more options with a button.
Please check source program for more.
