Controls

There are two differences between the controls and the Office ActiveX controls
1) windows form controls are implemented by extensible managed classes. Office controls are unmanaged
2) windows form controls have no concept of their location in relation to the containing workbook or document
You can use this.Controls collection to enumerate through all the controls

(View > Tab Order)

If you set the Font property on a form, prior to adding any controls then all the controls will inherit the font style for the form
You can select all the controls using (Ctrl + "A")
You can lock the controls (Format > Lock Controls). This prevents any of the controls on the form being accidently moved.
(Format > Align)
Aligning controls is made a lot easier by having the grid on the form
The alignments and sizing options

ActiveX Controls

You can easily expand the collection of controls that you have access to by loading ActiveX or COM controls.
When you add an ActiveX control to your Toolbox, Visual Studio displays them with the .NET controls and you can use them on your forms with few limitations. Visual Studio must create a wrapper for the control to enable it to be used in a .NET program.
