How to create a toolbar within an ActiveX Control

Hi all,

I try to create my own ActiveX Control that is shown as a toolbar. For that I used the VS2010 Wizard to create a MFC ActiveX Control.

After the automatic generation of some classes I add the member

C++

CToolBar m_toolbar

and the message handler for the "WM_CREATE" message which creates the method "OnCreate(...)".

C++

int MyCtrl::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
    if (COleControl::OnCreate(lpCreateStruct) == -1)
	return -1;

    // TODO:  Add your specialized creation code here
    m_toolbar.Create(this, WS_CHILD | WS_VISIBLE, IDC_MYCTRL_TOOLBAR);
    m_toolbar.LoadBitmap(IDB_TEXTCOMPLEMENT_TOOLBAR);
    m_toolbar.SetButtons(NULL, 5);

    m_toolbar.SetButtonInfo(0, IDC_MYCTRL_NEW,	    TBBS_BUTTON, 0);
    m_toolbar.SetButtonInfo(1, IDC_MYCTRL_DELETE,   TBBS_BUTTON, 1);
    m_toolbar.SetButtonInfo(2, IDC_MYCTRL_MODIFY,   TBBS_BUTTON, 2);
    m_toolbar.SetButtonInfo(3, IDC_MYCTRL_PREVIOUS, TBBS_BUTTON, 3);
    m_toolbar.SetButtonInfo(4, IDC_MYCTRL_NEXT,	    TBBS_BUTTON, 4);

    return 0;
}

C++

IDB_TEXTCOMPLEMENT_TOOLBAR

is a bitmap for the 5 buttons.

I do not get any error during compilation or runtime. The Create() and all other function finishing successfully.

Now I create a MFC Project with a Doc/View Architecture (also with the VS 2010 Wizard). To this project I add my control with the class wizard which generates a wrapper.
In the View-class' "OnCreate()" function I do the following:

C++

int CMFC_OCXView::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
    if (CView::OnCreate(lpCreateStruct) == -1)
    	return -1;
    
    // TODO:  Add your specialized creation code here
    m_toolbarCtrl.Create(NULL, WS_CHILD|WS_VISIBLE, CRect(0, 0, 200, 200), this, 1278);
    
    return 0;
}

where m_toolbarCtrl is a member of the type of my control's wrapper.

When I start the MFC application nothing is shown in the view.
I tried already to show other components on the view and they worked fine. E.g. I created some buttons in my ActiveX Control project the same way I did with the CToolBar.

I don't find the mistake why my toolbar is never shown.

Try adding CBRS_TOP to the Create() style mask.

Nope, this did not solve the problem.

your MFX app resources should be a bitmap and a toolbar resource, with your used ID auf 1278.

This did not help either.
Btw: why should I define the toolbar and its bitmap in the MFC app? Should not it be the way that an ActiveX control comes with all stuff it needs?

KarstenK 24-Jan-14 5:49am

it is the way the MFC works. This Create call requires such bitmap (in 16 bit) and a toolbar resource.

Or create it like you did it in the ActiveX-Control

I did not know that I also need a toolbar resource if I dynamically create the toolbar. But let me check it with a clean project. I will set-up everything again since I tried a lot of different approaches. Maybe they are disturbing each other in some way.

So, after playing around with new and clean projects I found the problem.
As described, the creation of my toolbar was always successful but I never was able to see something. The cause of this was that my toolbar was drawn where I could not see it.
You have to add the following bold marked lines to the "OnCreate"-method of the ActiveX Control:

C++

int MyCtrl::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
    if (COleControl::OnCreate(lpCreateStruct) == -1)
	return -1;
 
    // TODO:  Add your specialized creation code here
    m_toolbar.Create(this, WS_CHILD | WS_VISIBLE, IDC_MYCTRL_TOOLBAR);
    m_toolbar.LoadBitmap(IDB_TEXTCOMPLEMENT_TOOLBAR);
    m_toolbar.SetButtons(NULL, 5);
 
    m_toolbar.SetButtonInfo(0, IDC_MYCTRL_NEW,	    TBBS_BUTTON, 0);
    m_toolbar.SetButtonInfo(1, IDC_MYCTRL_DELETE,   TBBS_BUTTON, 1);
    m_toolbar.SetButtonInfo(2, IDC_MYCTRL_MODIFY,   TBBS_BUTTON, 2);
    m_toolbar.SetButtonInfo(3, IDC_MYCTRL_PREVIOUS, TBBS_BUTTON, 3);
    m_toolbar.SetButtonInfo(4, IDC_MYCTRL_NEXT,	    TBBS_BUTTON, 4);

    CRect rc;
    GetClientRect(&rc);
    rc.bottom = rc.top + 30;
    m_toolbar.MoveWindow(&rc);

    return 0;
}

This will move the toolbar down to the viewable area of the CView or whereever you want to add the toolbar.
