Branden, Most of what you need are included in Access, such as text boxes, labels, combo boxes, etc. These appear in the default set of controls in the 'tool box'. The 'other' controls are developed by third part vendors and are referred to as 'ActiveX'. These types of controls may require additional effort in order to deploy. For instance, you have to make sure the file that contains the control accompanies the database and is registered, etc in order to work properly...
In short, my answer to your original question would be that there are simply too many ActiveX controls out there to consider. My suggestion would be that if you have a special need, one that falls outside the capabilities of the native Access controls, that you may want to look on the net to see if anyone makes a control like you need...
Also worth noting is that the popularity of ActiveX controls is in part because they can be used in any development platform, such as c+, vba, etc, that supports them, which is almost all these days...
Hope all that helps. (And I hope I got all of that close enough to right…)...)
