I have a combobox displayed on a toolbar. When I select the dropdown arrow, it ASSERTS in CExtCmdManager::cmd_t::Deliver in the section:

if( bSend )
{
    if( !::SendMessage(
        hWndCmdTarget,
        nMsg,
        m_nCmdID,
        lParam
        )
    )
    {
        ASSERT( FALSE );
        return false;
    }
} // if( bSend )

Also, no matter what I do, I cannot get the vertical scrollbar to appear on the combo box - even though the number of items far outstrips the size of the drop down.

This is a very nice piece of software - and yes, I do have WS_VSCROLL set - however, delving back into my code I found that the problem was down to me overriding the combobox incorrectly. Sorry for any inconvenience caused to you here.

When is version 2.20 being released, and what are the costs associated with it?

Regards

Pete

Dear Peter O’Hanlon,

The new version is to be released by the end of this week. All associcated costs will be significantly less than the cost of the development ;-). As for the price of the commercial version is concerned, it will be less than the price of any UI library known to me.

Dear Peter O’Hanlon,

Thank you for your comment.

I have fixed this bug. Version 2.20 will be free of it.

As for as the scroll bar concerned I have a question. Is your combo box created with the WS_VSCROLL style?
