Properties Window

The Properties window has two tabs.
The Alphabetic tab displays all the properties in alphabetical order
The Categorized tab displays the properties grouped into logical categories.
Both tabs contain the same properties.
To change a property just click it and specify a new value.
If you select more than one control then the Properties window only displays the properties that are common to both.
The Image control's Picture property is a bit different because you either select a graphic file or you can paste a graphic directly from the clipboard. Using (Ctrl + V).

Tag Property

Every userform and control has a tag property.
This property does not represent anything specific and is empty by default.
You can use this tag to store your own information in.
For example you may have a series of textboxes on a userform.
The user may be required to enter text into some of the textboxes but not all of them.
You could use the tag property to indicate if a textbox is required to be filled in or not.

For Each objControl In UserForms.Controls 
   If TypeName(objControl) = "TextBox" Then 
      If objControl.Tag = "Required" Then 

      End If 
   End If 
Next objControl

All the controls on a userform make up the collection Userform1.Controls.
There is not a collection for each type of control so you must use the TypeName function to determine the type of each control.
