My colleague, Chris Alechko, has put together a great list of ActiveX controls and their use in SharePoint.
ActiveX Controls that must be allowed in the browser
- MSCAL.OCX (Calendar control – included with Microsoft Office Professional or installed with Microsoft Access)
- MSCOMCTL.OCX (Common Controls)
- MSCOMCT2.OCX (Common Controls2)
- OWSSUPP.DLL (ExportDatabase – To export a list to a Microsoft Office Access database, OpenDocuments – Launch Office applications to open documents)
- STSLIST.DLL (ListNet – Edit list in Datasheet view)
- NAME.DLL (Display presence information for people, integrate with Outlook and OCS)
- OISCTRL.DLL (OISClientLauncher – Integrate with Office Picture Manager)
- INLAUNCH.DLL (OpenXMLDocuments – Launch InfoPath to open forms)
- MSHTMLED.DLL (RTEDialogHelper – Allows use of rich text editor)
- OWSCLT.DLL (SpreadSheet Launcher – Integration with lists and Excel)
- STSUPLD.DLL (Multiple File Upload – Gives the option for multiple files to be uploaded)
Some organizations, like financial institutions and the US Goverment, explicitly control which ActiveX controls are enabled Internet Explorer Add-ons. If you do not allow these ActiveX controls for use on your SharePoint Collaboration sites, you will lose at a minimum the functionality in parentheses following the name of the control in the list above.
Microsoft Office SharePoint Server 2007 Collaboration Requirements
Chris also suggests the following Minimum Requirements for full functionality in MOSS Collaboration Sites:
- Memory: 1 GB Ram
- Operating System: Windows 2000, 2003, XP, Vista
- Web Browsers: IE 6.x/7.x/8.x
- Valid E-Mail Address
- JavaScript enabled
- ActiveX enabled
Reference
Update 10/08/2009: As Chad pointed out in the browser, Microsoft’s Level 1 browser support is for Internet Explorer 6 and above on Windows platforms. I’ve modified the minimum requirements for full functionality above. A functional but sub-optimal experience is provided in other browsers in the following list:
Operating System: Windows 2000, 2003, XP, Vista, 7, Linux/Unix, Mac OSX
Web Browsers: IE 6.x/7.x/8.x, Firefox 3.x, Safari 3.x
