I have noticed that a sample form I have seen will not allow any field to be modified unless the edit button or add button is pressed. I realize that individual fields have the enable function but how does one get all the fields enabled or disabled based on a command button?

Typically you can do it like this:

* editbutton.click()
thisform.SetAll("Enabled", .t., "Textbox") && or set to .F. to disable them.

Another way is to set some logical property, like form.lEditMode

* editbutton.click()
thisform.lEditMode = .t.
thisform.refresh()

and check the state of the property in yourcontrol.Refresh()

* somecontrol.Refresh()
this.enabled = thisform.lEditMode

Typically this code should go into .Refresh() of your control(s) class so it will be inherited by all instances.
