Please provide me some insight on mscomctl.ocx and visual basics common controls. I am unable to get the tree loaded (Microsoft Tabstrip Control 6.0 Microsoft Treeview control 6.0) which is needed for a website.
I tried rereg mscomctl.ocx, checking & resetting internet explorer security settings. I was able to get a prompt to allow mscomctl.ocx to install. I clicked allowed to install and the two activeX control now show in manage addons. But, I am still get a red X for the tree. Experts - what can be blocking the controls ? Is there another workaround for this to load? What is the relation of this ocx with office suite? Windows 7, IE 9  ... Please help

    Accepted Solution

    The controls that were provided with VB6 were designed to work in Windows applications compiled in VB6. Microsoft thus did not test them in other environments, and many of these did not work well in browsers or even other Microsoft applications such as Access. The reverse is also true, some controls that worked very well in other environments do not worked well in VB6.

    And since the VB6 controls are not supported in versions of Windows later than XP (see the System Requirements at, you can expect a few of them to give you problems in Windows 7.

    You might want also to search for a control that is not more than a decade old.
